Abstract

The utility model relates to medical equipment, particularly an injector. The utility model is characterized in that a hollow cavity is arranged in a casing, a stainless steel plate is arranged on the bottom face of the hollow cavity, an outlet conduit is arranged on the casing, a fixed interface sleeve is sheathed on the outlet conduit, the interface sleeve is connected according to the requirements, and an epidural catheter on which a plurality of inclined holes are provided is connected with the other end of the fixed interface sleeve. When the utility model is used, the utility model is completely embedded in subcutaneous tissue, the physic liquor transfused by the injector is injected in the hollow cavity so long as the skin at where the utility model is positioned is penetrated by the injector, and the physic liquor can flow out through the epidural catheter to be used at the required position. The utility model has the advantages of reliable performance, convenient operation, long service life and no bad tissue reaction through the clinical experiment.

Description

fully-buried nerve-block infusion device

This utility model relates to a kind of medical apparatus and instruments, especially a kind of infusion device.

At present both at home and abroad to carcinoma patient in late period, take directly to epidural intracavitary administration analgesics, concrete grammar is by routine operation epidural anesthesia method, but plug in conduit will not be pulled out, the long-term reservation,, its shortcoming is that plug in conduit is all drawn the skin outside, and open conduit is dangerous to epidural space, do not note slightly causing infection, cause severe complications.And epidural catheter is very thin, as easy as rolling off a logly extracts slippage, and main is patient's inconvenience in life, and mood also is affected.

The purpose of this utility model be to provide a kind of infusion device can all imbed subcutaneous, easy and simple to handle, the device unobstructed, safe and reliable, can for a long time reusable full embedded type nerve block infusion device.

The technical solution of the utility model is: with medical grade silicone rubber is that material is made a shell, in shell, establish a cavity, on the bottom surface of cavity, put a corrosion resistant plate, the shell right part is established an output duct, output duct communicates with cavity, also be provided with the plurality of fixed aperture on the shell, be nested with a fixed interface cover at the output duct end, socket one epidural catheter in fixed interface cover right-hand member, as change other various sizes and planform conduit, insert different blood vessel as required, tube chamber and other position, can also carry out the arteriovenous chemotherapy, the splanchnocoel chemotherapy, tumor vessel is cloudy to stagnate, high-energy infusion treatment etc., during use, in local anesthesia, get the epidural space of corresponding spinal column according to patient's pain position, insert epidural catheter, inject a small amount of analgesics, when waiting patient's pain obviously to reduce, use hypodermic tunnel guiding draw point, arrive between the preceding thoracic wall at the spinal column point of puncture, pass hypodermic tunnel, the epidural catheter near-end is caused preceding thoracic wall, be inserted into degree of depth 1cm in the defeated syringe output duct mouth, put fixed interface cover (reinforcing ligation together) then with No. 4 lines, infusion device is embedded in the subcutaneous wound of closing, and No. 5 syringe needles generally commonly used thrust, and withdraw from slightly after running into metallic plate, can inject various analgesics, the back that finishes comes liquid to stay filling with rare liver.

The utlity model has esy to use, safe and reliable, characteristics that can life-time service, through clinical experiment, various patients with advanced cancer are imbedded inorganization untoward reaction behind this utility model, inject 300 surplus time ne-leakage phenomenon, postoperative surplus injection in May is still very unobstructed.

Fig. 1 is overall structure figure of the present utility model;

Fig. 2 is an epidural catheter structural representation of the present utility model;

Set forth most preferred embodiment of the present utility model below in conjunction with accompanying drawing: as shown in the figure, by shell (1), corrosion resistant plate (2), conduit (3) is formed, it is characterized in that shell (1) can make the straw hat shape, in shell (1), establish a cavity (4), its volume is 0.35cm, on the bottom surface of cavity (4), put a corrosion resistant plate (2), shell (1) right part is established an output duct (5), output duct (5) communicates with cavity (4), shell (1) is provided with plurality of fixed aperture (6), output duct (5) end is nested with a fixed interface cover (7), socket one epidural catheter (8) in fixed interface cover (7) right-hand member.The structure of epidural catheter (8) can be: the right-hand member sealing, be provided with side direction aperture (9) at left end, and the right-hand member of epidural catheter (8) inserts interface cover (7) right-hand member, its external diameter can be 1.20mm, internal diameter is 0.8mm, long 950mm, and aperture (9) can be 4.

Claims

1, a kind of nerve block infusion device of imbedding entirely, form by shell (1), corrosion resistant plate (2), conduit (3), it is characterized in that establishing in the shell (1) cavity (4), on the bottom surface of cavity (4), put a corrosion resistant plate (2), shell (1) right part is established an output duct (5), and output duct (5) communicates with cavity (4), and shell (1) is provided with plurality of fixed aperture (6), output duct (5) end is nested with a fixed interface (7), socket one conduit (8) in fixed interface cover (7) right-hand member.

2, the nerve block infusion device of imbedding entirely according to claim 1 is characterized in that the structure of conduit (8) can be: the right-hand member sealing, be provided with plurality of side to aperture (9) at left part, and the right-hand member of this epidural catheter inserts and connects cover (7) right-hand member.
