Abstract
The invention provides a novel guide wire of a gastric tube. The novel guide wire comprises a guide wire strip. A plastic reinforcement head is further wrapped on the outside of a head of the guide wire strip, the guide wire is further provided with a handle, and the tail of the guide wire strip is connected with the handle; the lower portion of the handle is a hollow and downwardly open plug, and the plug is matched with a gastric tube joint and is used for being plugged in the gastric tube joint and connecting the handle with the gastric tube joint; and the upper portion of the inside of the handle is an injection cavity, an opening of the injection cavity is sealed by a sealing film, and the injection cavity is communicated with a hollow portion of the plug. The novel guide wire is good in lubricating effect, the plastic reinforcement head has a suspension effect, and friction between the guide wire strip and the wall of the gastric tube is reduced, so that the guide wire strip can be drawn easily; the head of the guide wire strip is effectively prevented from penetrating through an outward open hole at the front end of the gastric tube to destroy gastric and intestinal tissues; and the novel guide wire is doubly sealed under the action of the plug and the action of the sealing film of the injection cavity, and the phenomenon of reverse ejection of contents of the stomach of a patient is stopped.
Description
Technical field
The present invention relates to a kind of stomach tube seal wire.
Background technology
The seal wire of stomach tube helps out when penetrating stomach tube, extract stomach tube and adjusting the stomach tube position, and it is inserted in the tube chamber of stomach tube in use.Present seal wire, its head is formed on the sealing lousiness of steel wire head when being steel wire making seal wire melting consists of bead, when the pull seal wire was adjusted the stomach tube position, conductive filament head might pass the outside through hole of stomach tube front end and destroy gastrointestinal section tissue, forms easily malpractice; When common seal wire is extracted stomach tube out when guiding finishes since excessive being difficult to of resistance extract; And when the stomach hypertonia, gastric content can be regurgitated out stomach tube along seal wire.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Novel ventricular canal seal wire, and its pull in stomach tube easily can not pass stomach tube yet to be caused malpractice, also can not allow gastric content regurgitate out stomach tube along seal wire.For this reason, the present invention by the following technical solutions: it comprises the seal wire bar, and the head of described seal wire bar also is surrounded by plastics outward and strengthens head, and described seal wire also is provided with handle, and the afterbody of described seal wire bar links to each other with handle; The bottom of described handle is boring and the chock plug opened to cephalad direction, and described chock plug and stomach duct connector coincide, and is used for plug and gets lodged in stomach duct connector and handle is connected with stomach duct connector; Top in the described handle is injecting cavity, and the oral area of described injecting cavity is sealed by diaphragm seal, and the hollow part of described injecting cavity and chock plug communicates.
On the basis of adopting technique scheme, the present invention also can adopt following further technical scheme:
The afterbody of described seal wire bar is provided with dop, the dop deck clamping in described dop and the handle, and described dop deck is in the middle part in the handle, and described injecting cavity and chock plug are in respectively the above and below of dop deck.
Described plastics are strengthened the diameter of head greater than the aperture of the outside perforate of stomach tube front end.
Described chock plug is the taper chock plug, and collar or the projection of projection arranged on the chock plug, and described stomach duct connector inwall is provided with the draw-in groove that cooperates with collar or projection.
Scribble hydrophilic coating on the described plastics reinforcement head.Further, scribble hydrophilic coating on the described seal wire bar.
Described chock plug is the taper chock plug.
Owing to adopt technical scheme of the present invention, the present invention can be by to the injecting cavity injecting normal saline, and normal saline enters stomach tube through described hollow part and comes hydrophilic coating on the humidifying stomach tube inwall, strengthens lubricity and is conducive to the pull of seal wire in stomach tube; And, the head of seal wire bar of the present invention is strengthened head for the plastics that strengthen, plastics are strengthened head can play self-lubricating function, and its plastics are strengthened the diameter of head greater than the aperture of the opening of stomach tube front end, and when the pull seal wire was adjusted the stomach tube position, not only lubricant effect was better like this, plastics are strengthened head and are played built on stilts effect, the friction of seal wire bar and stomach tube wall reduces, so that the pull of seal wire bar is lighter, and effectively stops seal wire bar head to pass the outside perforate of stomach tube front end and destroys gastrointestinal section tissue; Simultaneously, the present invention adopts the diaphragm seal dual-plugging of chock plug and injecting cavity, has stopped the phenomenon that gastric content is regurgitated.
Description of drawings
Fig. 1 is the sketch map of seal wire provided by the present invention.
Fig. 2 is the enlarged diagram of seal wire bar head among Fig. 1.
Fig. 3 is the combination sketch map of seal wire shown in Figure 1 when being applied to double-cavity stomach tube.
The specific embodiment
With reference to accompanying drawing.Seal wire provided by the present invention comprises seal wire bar 1, and the head of described seal wire bar also is surrounded by plastics outward and strengthens 2, and described seal wire also is provided with handle 3, and the afterbody of described seal wire bar 1 links to each other with handle 3; The bottom of described handle is boring 40 and opens 42 chock plug 4 to the seal wire cephalad direction, and described chock plug 4 coincide with stomach duct connector 101, is used for plug and gets lodged in stomach duct connector 101 and handle is connected with stomach duct connector; Top in the described handle is injecting cavity 5, and the oral area of described injecting cavity 5 is by diaphragm seal 6 sealings, and the hollow part 40 of described injecting cavity 5 and chock plug communicates.
The afterbody of described seal wire bar 1 is provided with dop 7, dop deck 8 clampings in described dop 7 and the handle, and described dop deck 8 is in the middle part in the handle, and described injecting cavity 5 and chock plug 4 are in respectively the above and below of dop deck 8.
Described plastics are strengthened the aperture of the outside perforate 102 of stomach tube 100 front ends that 2 diameter penetrates greater than seal wire, and when described opening was circular hole, this aperture was its diameter, and when perforate was elliptical aperture, described aperture was the length of its minor axis.
Described chock plug 4 is the taper chock plug.
Collar 41 or the projection of projection are arranged on the chock plug 4, and described stomach duct connector 101 inwalls are provided with the draw-in groove 103 that cooperates with collar or projection.
Described plastics are strengthened on 2 and are scribbled hydrophilic coating.Further, scribble hydrophilic coating on the described seal wire bar 1.
In Fig. 3, drawing reference numeral 100 is stomach tube, and stomach tube adopts double-cavity stomach tube in the present embodiment.In force, stomach tube seal wire provided by the present invention can be applicable to various stomach tubes.
