Definitions
- the present invention relates to syringes and other devices for removing blood from and administering medical fluids to a patient.
- the present invention relates to novel devices which can be used to both collect blood from a patient and administer medicines and other medical fluids to the patient using a single needle insertion.
- Background of the Invention Patients who undergo medical treatment in hospitals frequently require both extraction of blood for blood testing purposes and intravenous administration of medical fluids. Proper treatment of the patient may require that the blood be extracted and the medical fluids administered repeatedly and on a regular basis. In the past, this procedure has required that multiple needle insertions be made in various locations of the patient's body to access veins such as the external or internal jugular, subclavian, cephalic, femoral or saphenous veins.
- a device which facilitates both collection of blood from and administration of medical fluids to a patient on a repeated basis using one, rather than multiple, needle insertions and which prevents premature collapse of a vein by utilizing intrinsic venous blood pressure to collect blood. Disclosure of the Invention The present invention is generally directed to novel devices which can be used to both collect blood samples from and administer medical fluids to a patient on a repeated and continual basis using one rather than multiple needle insertions. The devices are capable of removing blood from one of the patient's veins using the intrinsic venous pressure of the blood and capillary action of the device, thereby preventing vacuum-induced collapse of the vein.
- the devices typically include a main tubing segment confluently connected to a cannula for insertion in the patient's vein.
- the device is used to collect blood by attaching an empty blood collection syringe to the syringe port, inserting the cannula in the patient's vein, allowing passive flow of blood from the main tubing segment into the volumeter under intrinsic venous blood pressure and capillary action, and then facilitating active flow of blood from the volumeter into the blood collection syringe by extending the syringe plunger.
- the blood-filled syringe may be replaced by additional empty blood collection syringes and the procedure repeated, as needed, depending on the quantity of blood to be collected.
- the device may be used to administer medical fluids to the patient by first drawing the residual blood from the main tubing segment and volumeter, flushing the main tubing segment with sterile normal ' saline and administering the fluids to the patient through the main tubing segment from a medical fluid syringe or catheter attached to the syringe port or to an auxiliary port connected to the main tubing segment.
- a membrane permeable to air, but not to liquid is attached distal to the volumeter, which may be a chamber, an elongated folded or coiled tubing, or any other element which is capable of enabling visual estimation of the rate of blood flow toward the membrane.
- the syringe port branches from the main tubing segment and accepts a syringe to collect blood for tests.
- the volumeter may be removed from the device, leaving the syringe port available for accepting a medication-filled syringe for administration of medical fluids to the patient.
- a deformable reservoir is provided in fluid communication with the cannula and volumeter.
- the reservoir may be protected in the barrel of a syringe or other protective covering withNented openings along its barrel. After the blood-drawing procedure is completed using the blood collection syringe, residual blood may be effectively removed from the device by flushing the tubing with sterile normal saline. Removal of the reservoir unit from the device allows the remaining part of the device to be used as an ordinary "Y" tubing.
- a main tubing segment is confluently connected to a cannula for insertion in the patient's vein.
- a syringe port and a device for estimating the rate of blood flow, hereinafter called a volumeter branch separately from the main tubing segment.
- the device is used to collect blood by attaching an empty blood collection syringe to the syringe port, inserting the cannula in the patient's vein, allowing passive flow of blood from the main tubing segment into the volumeter under intrinsic venous blood pressure and capillary action, and then facilitating active flow of blood from the volumeter into the blood collection syringe by extending the syringe plunger.
- the blood-filled syringe may be replaced by additional empty blood collection syringes and the procedure repeated, as needed, depending on the quantity of blood to be collected.

- the device 1 includes a main tubing segment 2 which is typically a flexible material.
- a hub 4 of a cannula 3 is threadibly or otherwise attached to the main tubing segment 2.
- a tubing bifurcation 5 is provided in the end of the main tubing segment 2 which is opposite or distal to the cannula 3, and the tubing bifurcation 5 may be continuous with or a separate element with respect to the main tubing segment 2.
- a tubing clamp 6 is provided on the main tubing segment 2 between the cannula hub 4 and the tubing bifurcation 5.
- the tubing clamp 6 may be any type of clamp which is capable of facilitating selective and reversible blocking of the flow of fluids through the main tubing segment 2.
- the tubing clamp 6 is preferably capable of one-handed operation.
- a syringe tubing segment 9 extends from a syringe tubing leg 5a of the tubing bifurcation 5 and may be continuous with or a separate element with respect to the tubing bifurcation 5.
- a syringe port 10 is provided in the end of the syringe tubing 9 which is opposite the tubing bifurcation 5.
- the syringe port 10 may be a needle-less syringe port such as a female luer-lock connector element or other type of threaded element known by those skilled in the art, or may be any type of threadless connector which is capable of providing reversible and secure fluid communication between a syringe 13 and the syringe tubing segment 9.
- the syringe 13 may be conventional and typically includes a cylindrical syringe barrel 14 having a syringe connector 15 such as a male luer-lock connector element, for example, or other structure which is capable of removably and securely engaging the companion syringe port 10.
- the syringe 13 typically further includes barrel flanges 16 and an extendible and retractable syringe plunger 17.
- a collector tubing segment 19 extends from a collector tubing leg 5b of the tubing bifurcation 5 and may be continuous with or a separate element with respect to the tubing bifurcation 5.
- An indicator unit 18 of the device 1 includes a volumeter tubing segment 20 which is provided in fluid communication with the collector tubing segment 19.
- the indicator unit 18 may be removably attached to the collector tubing segment 19 by a tubing connector 21 , which may include a receiver element 22 provided on the collector tubing 19 and an insertion element 23 provided on the volumeter tubing segment 20, as shown.
- the receiver element 22 may be provided on the volumeter tubing segment 20 and the insertion element 23 may be provided on the collector tubing segment 19.
- the receiver element 22 may be a syringe port adapted for removably receiving a syringe for the administration of medical fluids to a patient, as hereinafter further described. It is understood that the indicator unit 18 may be fixedly rather than removably attached to the collector tubing segment 19.
- a connector 7 may be provided between the clamp 6 and the bifurcation 5 to facilitate disconnecting the syringe tubing segment 9 and syringe port 10, together with the connected indicator unit 18, from the main tubing segment 2, in order to discard the syringe tubing segment 9 and indicator unit 18, as desired.
- the indicator unit 18 may further include a volumeter 26, which is typically a volumeter chamber and made of a transparent material, provided in the volumeter tubing segment 20.
- the volumeter 26 may be an elongated segment of transparent coiled or folded tubing, as hereinafter described with respect to FIGS. 2, 2A and 4.
- Membrane tubing 28 of the indicator unit 18 extends from the volumeter 26, and an air-permeable membrane 29 is provided on the membrane tubing 28.
- the air-permeable membrane 29 is preferably impermeable to liquids and may be any structure which is capable of facilitating bi-directional flow of air in the membrane tubing 28 toward the membrane 29 or bi-directional flow of air between the volumeter chamber 26 and the membrane tubing 28 while preventing the flow of blood out from the membrane tubing 28.
- the device 1 is initially used to remove blood from a subcutaneous vein of a patient 30 for blood sampling purposes. Accordingly, the clamp 6 is adjusted to the closed position to seal the main tubing segment 2 between the cannula 3 and the tubing bifurcation 5.
- the tubing connector 21 is inspected to ensure an airtight and fluid-tight connection between the collector tubing segment 19 and the volumeter tubing segment 20 of the indicator unit
- the cannula 3 With the main tubing segment 2, the syringe tubing segment 9, the collector tubing segment 19 and the indicator unit 18 containing air, the cannula 3 is inserted into the vein of the patient 30 through the skin, as shown. The cannula 3 is typically taped in place to immobilize the device 1 on the patient 30. After the syringe connector 15 of the syringe 13 is attached to the syringe port 10 of the syringe tubing segment 9, the clamp 6 is adjusted to open the main tubing segment 2.
- the syringe plunger 17 is slowly extended from the syringe barrel 14 of the blood collecting syringe 13 to initially draw air from the syringe tubing segment 9 and into the syringe barrel 14 of the syringe 13, thereby inducing a drop in air pressure inside the syringe tubing segment 9 relative to both the pressure in the collector tubing segment 19 and the intrinsic venous pressure in the main tubing segment 2.
- This pressure drop causes blood to flow from the volumeter chamber 26, the volumeter tubing segment 20 and the collector tubing segment 19, respectively, and enter the syringe tubing segment 9 and then the syringe barrel 14 of the syringe 13.
- This extension of the plunger 17 from the syringe barrel 14 at a relatively slow, controlled rate ensures that blood is extracted from the vein of the patient 30 and into the device 1 using the intrinsic flow pressure of the blood in the vein and prevents application of vacuum pressure to the vein which would tend to collapse the vein and hinder further flow of blood therefrom, as well as prevents or minimizes hemolysis of red blood cells in the extracted blood.
- the syringe plunger 17 is pulled from the syringe barrel 14 at a rate which is sufficient to facilitate maintaining a substantially constant volume of blood in the volumeter chamber 26 as blood continues to be obtained from the main tubing segment 2, through the syringe tubing segment 9 and into the blood collection syringe 13.
- the volumeter 26 may be omitted from the indicator unit 18, in which case the indicator unit 18 may be a segment of clear tubing or any other element which is capable of enabling a user of the device 1 to visually inspect the progress of blood flow therethrough and prevent the air/fluid interface from passing beyond the bifurcation 5 to the syringe tubing segment 9 while obtaining the blood sample.
- the tubing clamp 6 is adjusted to block further flow of blood through the main tubing segment 2.
- the syringe plunger 17 of the syringe13 is extended from the syringe barrel 14 until all residual blood has been drawn from the indicator unit 18, the collector tubing segment 19 and the syringe tubing segment 9, and into the syringe barrel 14. Simultaneously, air is drawn through the indicator unit 18 through the membrane 29, the collector tubing segment 19 and the syringe tubing segment 9, respectively, until these elements are filled with air.
- the blood-filled syringe 13 is then removed from the device 1 by disconnecting the syringe connector 15 from the syringe port 10, and the blood collected in the syringe 13 is subjected to blood testing.
- Additional blood samples may be collected in an additional syringe or syringes, as needed, by attaching each additional empty syringe 13 to the syringe tubing segment 9 at the syringe port 10 and collecting the additional samples of blood in the syringe 13 or successive syringes 13, in the manner heretofore described.
- the device 1 may be used to administer medical fluids to the patient 30, as follows.
- a syringe 13, the barrel 14 of which contains a supply of saline flush solution, is initially attached to the syringe port 10.
- the saline solution is ejected therefrom and flows through the syringe tubing segment 9, the collector tubing segment 19, the volumeter tubing segment 20 and into the volumeter chamber 26, respectively.
- the volumeter tubing segment 20 may then be disconnected from the collector tubing segment 19 at the tubing connector 21 and discarded along with the volumeter chamber 26, the membrane tubing 28 and the membrane 29 of the indicator unit 18, as desired.
- the tubing clamp 6 is then again adjusted to the open position and depression of the syringe plunger 17 into the syringe barrel 14 is continued to flush the main tubing segment 2 with saline flush solution.
- a replacement syringe 13 containing a fluid medication or a catheter (not shown) connected to an IV bag (not shown) may then be attached to the syringe port 10 for the administration of medical fluids to the patient 30 through the syringe tubing segment 9, or alternatively, through the syringe port 22, the collector tubing segment 19 and the main tubing segment 2, respectively.
- a replacement syringe 13 containing a fluid medication or a catheter (not shown) connected to an IV bag (not shown) may then be attached to the syringe port 10 for the administration of medical fluids to the patient 30 through the syringe tubing segment 9, or alternatively, through the syringe port 22, the collector tubing segment 19 and the main tubing segment 2, respectively.
- a replacement indicator unit 18 may then be attached to the collector tubing segment 19 at the tubing connector 21.
- the plunger 17 of syringe 13, emptied of the medical fluid contents, is then extended to draw residual medical fluids from the indicator unit 18 and syringe tubing segment 9, and the syringe 13 is removed from the syringe port 10 and discarded.
- the clamp 6 is now opened, allowing fluid frorti main tubing segment 2 to flow toward membrane 29.

- the reservoir 69 is formed typically of a thin plastic material such as SARAN WRAP (trademark) or a rubber material or other easily deformable material that allows the interior volume of the reservoir 69 to be maintained at ambient air pressure.
- the reservoir 69 includes an intake end 69a which is typically secured in the syringe connector 65 and has an intake opening (not shown) which faces the syringe port 60.

- Blood continues to flow from the main tubing segment 32 and collector tubing segment 49, through the tubing connector 51 and volumeter tubing segment 50, respectively, and enters and collects in the volumeter 56.
- this blood is collected in the blood collecting reservoir 69 (FIG. 3) and may later be expelled from the covering syringe 63 as an additional blood sample, as hereinafter further described.
- the syringe plunger 47 of the blood collection syringe 43 is slowly extended from the syringe barrel 44 of the blood collecting syringe 43 to initially draw air from the syringe tubing segment 39 and into the syringe barrel 44 of the syringe 43, thereby inducing a drop in air pressure inside the syringe tubing segment 39 relative to the air pressure in the collector tubing segment 49.
