Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1, a three-way stomach tube of portable, including stomach tube body 1, this stomach tube body is the pipe of polyurethane material, the front end that the stomach tube body is used for stretching out the external is equipped with nipple 2, this nipple is a straight short pipe that an axis is sharp, two ports of nipple, one of them cup joints with the pipe, another forms and is used for washing, get liquid and send into food, medicine in vivo annotates the mouth of food, be equipped with a side direction takeover 3 on the lateral surface of nipple, the side direction takeover link up with the inner chamber of nipple, the side direction takeover is used for the tube coupling with intestines and stomach pressure reducer, the tip that the side direction takeover is used for connecting the intestines and stomach pressure reducer inclines to annotating the mouth of food, the axis that makes the side direction takeover and the axis of annotating the mouth of food the contained angle be the acute angle contained angle, preferably 10 ~ 30, for example be 25 in this embodiment. The inlet for taking liquid, flushing, injecting food and injecting medicine is separated from the inlet for negative pressure drainage by the short connecting pipe with the function of three-way. Meanwhile, the end part of the lateral connecting pipe is obliquely arranged towards the food injection port to form a small acute angle so as to realize a straight channel of the negative pressure drainage pipeline relative to the catheter body as much as possible, and the lateral connecting pipe is prevented from flowing to the negative pressure drainage pipeline when fluid food or liquid medicine is fed to the catheter body to flow adherent.
For realizing annotating the food mouthful sealed under general non-operating condition, tee bend stomach tube still is equipped with and annotates the first stifled cap 4 that food mouthful cooperation was used, it connects two to set up the size to combine stomach tube among the prior art to annotate food mouthful, wherein the osculum is used for sending into liquid medicine, fluid food, the macrostoma is used for sending into paste or ropy material, first stifled cap includes 41 logical chamber stifled cap with the internal diameter adaptation of annotating food mouthful, with the stifled cap head 42 of the internal diameter adaptation of leading to chamber stifled cap, lead to chamber stifled cap and stifled cap head and be connected to on the nipple through first connecting band 43. Can realize the negative pressure drainage when eating the mouth to guarantee to annotate when edible mouthful is sealed, the maximum depth that first stifled cap inserted and annotates edible mouthful is less than or equal to the junction of side direction takeover and nipple to annotate the length of edible mouthful, and when in order to prevent negative pressure drainage, thereby partial flow direction annotates edible mouthful environment is annotated to the pollution of edible mouthful when liquid in the stomach is outwards drawn forth, thereby it equals to select both here, as shown in figure 1, stifled cap head inserts stifled cap logical intracavity, stifled cap leads to the chamber and inserts in annotating edible mouthful, the front end of stifled cap head stretches out stifled cap logical chamber this moment, when first stifled cap inserts and annotates edible mouthful, the front end of stifled cap head is located the junction of side direction takeover and nipple. In order to maintain the sealing performance of the lateral connecting pipe when the lateral connecting pipe is empty, a second plugging cap 5 is arranged on the lateral side of the lateral connecting pipe, and the second plugging cap is connected with the lateral connecting pipe through a second connecting belt 51.
Because need seal the mouth of pipe for 1 hour so that the liquid medicine is digested in the stomach after adding the medicine through annotating the food mouth, also need to close the side direction takeover (also need to close when generally sending into food) that is connected with negative pressure drainage pipeline this moment, this is relatively easy to be operated to disposable stomach and intestine pressure reducer, negative pressure drainage pipeline etc. can buckle, but to non-disposable stomach and intestine pressure reducer, frequent pipeline of buckling causes the pipeline to damage easily, influences stomach and intestine pressure reducer's use, and medical cost also can increase moreover. In order to deal with the situation, as shown in fig. 2, the lateral connecting pipe is composed of a lateral short pipe 31 and an elastic connecting pipe 32, the elastic connecting pipe only needs to be capable of resisting the negative pressure drainage without obvious deformation, the material of the elastic connecting pipe is the same as that of the stomach tube body, and the material of a common hose can be adopted, and the thickness of the pipe wall is made to be a little. The end part of the lateral short pipe is provided with a conical table surface, the port part of one end of the elastic connecting pipe is provided with a conical flaring, the elastic connecting pipe is sleeved with the conical table surface of the short pipe through the flaring, and the other end of the elastic connecting pipe is connected with a negative pressure drainage pipeline of the gastrointestinal pressure reducer. Thus, when the tube needs to be closed, the elastic connecting tube only needs to be clamped by the clamp.
In order to further improve the sealing performance of the elastic connection tube, a conical radial protrusion 32-1 is provided on the inner wall of the elastic connection tube, and as shown in fig. 3, the radial protrusion is located on the radial circular cross section of the elastic connection tube along the radial section of the elastic connection tube. The inner wall of the elastic connection tube is further provided with a fitting groove 32-2 opposite to the radial protrusion so that the radial protrusion can be fitted into the fitting groove when being clamped at a portion corresponding to the radial protrusion by the clip. In the case of the general hose 6, as shown in fig. 4, when the general hose is clamped, the sealing performance is affected by the gaps 62 formed at both ends of the slit 61 due to the deformation and thickening of the general hose to both sides. As shown in fig. 5, by the arrangement of the radial protrusion and the fitting groove, the radial protrusion is inserted into the fitting groove at the time of clamping to absorb a part of the deformation, thereby reducing or eliminating the gap. Of course, in order to facilitate the determination of the clamping positions corresponding to the radial protrusions and the mating grooves, the outer walls corresponding to the radial protrusions and the mating grooves are respectively provided with a clamping groove 32-3, forming a pair of clamping grooves for cooperating with the clip. In order to further enhance the sealing performance during clamping, buffer seams 32-4 are arranged at two ends of the diameter perpendicular to the connecting line of the matching groove and the radial protrusion of the elastic connecting pipe, each buffer seam is a section of V-shaped groove extending on the inner wall of the elastic connecting pipe, and the buffer seams are located at two ends of each clamping seam when the elastic connecting pipe is clamped, so that clamping deformation is further absorbed, and gaps caused by deformation are eliminated.
