Abstract
The utility model relates to a stomach tube with a three-way valve. The utility model can be used for clinical liquid food or medicine feeding through the noses of the patients having no eating capacity. The utility model is characterized in that the utility model is formed by that a flexible medical plastic tube is inserted in the three-way valve which can switch liquid passages, wherein, the three-way valve is positioned at the opening of the stomach tube and can conveniently switch liquid passages; the phenomenon of liquid overflow during the course of liquid food or medicine feeding through noses can be prevented; the utility model is thrown off after the utility model is used for one patient, and thus the cross infection caused by the repeated use of the utility model can be prevented.
Description
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of patient when not having the feed ability, the stomach tube that carries out nasal feeding.
Clinically, when patient does not have the feed ability, need stomach tube is inserted gastric from the nostril, liquid food is injected gastric.This kind feed mode claims nasal feeding.In the nasal feeding process, empty needle or transfusion device are connected with the port that stomach tube exposes, and liquid food is injected into or splashes into gastric, thereby reach the purpose of feed.There is following defective in this stomach tube: the one, after the liquid food of suction empty needle has been annotated, need pull out and suck liquid food again and inject to gastric again, need in this process the stomach tube opisthotonos, and also need the stomach tube opisthotonos to wrap up the mouth of pipe with sterile gauze after each nasal feeding, reuse cover skin or clip are fixed, are operated time-consuming and bother; The 2nd, the stomach tube external port is connected with empty needle or transfusion device and does not tightly cause liquid food excessive during nasal feeding; The 3rd, stomach tube is a rubber, and repeated disinfection is used and caused aging, adhesion, causes pore inaccessible or not smooth.Reuse cross infection also takes place easily.
The purpose of this utility model be to people provide a kind of simple to operate, save time, liquid food is not excessive, and the stomach tube of the band three-way valve of cross infection does not take place.
This utility model is realized by following structure.
The stomach tube that has three-way valve, it is to be that solid plastic tube is as stomach tube by a butt head, the liquid food that the top laterally that communicates with the stomach tube pore of the insertion end termination portion of stomach tube tilts or the inclined hole of medicine, the liquid food that staggers mutually on the close stomach tube tube wall of inclined hole or the cinclides of medicine, the three-way valve that is installed on the stomach tube exposed junction port by grafting constitutes.Three-way valve is by the inner chamber of the truncated cone-shaped spool of packing into of valve casing, truncated cone-shaped, the pipe joint of the grafting stomach tube that becomes overall structure with valve casing and communicate with valve shell cavity on the outer wall of valve casing, is connected two pipe joints of empty needle when injecting liquid food or medicine, screws in the end cap that seals the mouth of pipe respectively by screw thread on two pipe joints.The spool design of truncated cone-shaped has clear opening and side opening relative with the pore of three joints on the valve casing and that communicate, the annular protrusion muscle that has the annular slot on the truncated cone-shaped lumen port inwall with valve casing to match in stub end design is with the spool location and play sealing function.The stub end of spool has the spanner that becomes the switch fluids passage of integral body with spool.
The stomach tube that has three-way valve described in the utility model, when needs are given patient's nasal feeding, an end that stomach tube is had oblique side opening and cinclides injects through gastric from the nostril, the spanner of swivel tee valve communicates two holes of three-way valve core respectively and the end cap on the pipe joint is screwed off with stomach tube and pipe joint, in the mouth of pipe of the empty needle insertion tube joint of suction liquid food, liquid food is injected gastric by stomach tube, also can be connected, continue to splash into nutritional solution to patient with transfusion device.Make the pore of three pipe joints on three through holes and the valve casing on the spool all relative if can move spanner when need injecting medicine, connect empty needle or transfusion device, reach the purpose of injection medicine from another pipe joint.In using operating process, only need the turn spanner to change fluid passage, owing in operating process, do not bend stomach tube, thus the generation that has solved liquid spill.Owing to stomach tube, three-way valve all adopt plastic raw materials to make, with low cost again, to promptly abandoning after patient's use, stopped the generation of cross infection.
Below in conjunction with embodiment and accompanying drawing in detail this utility model is described in detail.
