Abstract
The utility model relates to a catheter for intraperitoneal chemotherapy, and mainly solves the problem of non-uniform administration. The front end of the body of the catheter for intraperitoneal chemotherapy is a cone; multiple liquid injection holes are staggered on the cone and the side wall of the catheter body connected with the cone; and the outer wall of the catheter body corresponding to each liquid injection hole is correspondingly covered with a hole cap, so that the fluid can flow out of the catheter body only from the inside of the catheter body. The catheter can uniformly disperse the liquid medicine and is favorable for the early rehabilitation of the diseased region; and the catheter prevents internal blockage and avoids the side effect caused by multiple times of injection of heparin normal saline..
Description
Technical field
This utility model relates to when the intraperitoneal tumor carried out chemotherapy employed a kind of intraperitoneal chemotherapy and uses conduit.
Background technology
The belly cavity tumor patient is when carrying out chemotherapy, and intraperitoneal chemotherapy is that to implant the patient for a long time Intraabdominal with conduit, at present; The intraperitoneal chemotherapy of using is clinically implanted Intraabdominal nose end with conduit and generally is open, therefore in use, often has blood and gets in the tube chamber; The obstruction conduit condenses in tube chamber; The general way that solves is an injecting heparin normal saline in the conductive pipe, and because of patient's self reason, has side effects sometimes; In addition, conduit commonly used has only a drug delivery port, makes to be unfavorable for the diseased region integral rehabilitation by the only even of medicinal liquid diffusion.
Summary of the invention
In order to address the above problem, this utility model provides a kind of intraperitoneal chemotherapy to use conduit.This conduit can not stop up in the generator tube, and can make the medicinal liquid even diffused, is beneficial to the early recovery of diseased region.
The technical scheme of this utility model is: a kind of intraperitoneal chemotherapy is used conduit; Comprise catheter body; Wherein, the front end of said catheter body is a cone, is staggeredly distributed with some liquid injection holes on said cone and the connected catheter body sidewall; The porose medicated cap of all corresponding covering on the corresponding catheter body outer wall of each liquid injection hole, limit fluid can only flow to outside the catheter body in catheter body.
Described hole medicated cap is laminar, and mutually bonding with the catheter body outer wall in the side near the catheter body front end; The axis of said liquid injection hole all favours the axis of catheter body, and the tail end of the equal conductive pipe body of the port of export tilts.
The beneficial effect of this utility model is: owing to adopt above-mentioned technical scheme, on the catheter wall of on the front end tapered wall of conduit and rear end, be staggeredly distributed with some liquid injection port, and on liquid injection port, be provided with the hole medicated cap; When injection; Under the effect of medicinal liquid pressure, each hole medicated cap opens, and medicinal liquid is flowed out from staggered liquid injection port smoothly; The diffusion of medicinal liquid can be more even, is beneficial to state of an illness early recovery; After medicinal liquid is totally lost; Automatically close under the effect of each hole medicated cap fluid pressure outside pipe, thereby stop blood and other body fluid to get in the tube chamber, avoid blockage phenomenon; Thereby need not the injecting heparin normal saline, avoid causing the generation of side effect because of the multiple injection heparin-saline.

1-catheter body among the figure, 2-liquid injection hole, 3-hole medicated cap, 4-front end.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further:
By Fig. 1 and shown in Figure 2; This intraperitoneal chemotherapy is used conduit, comprises catheter body 1, wherein; The front end 4 of said catheter body 1 is a cone; Be staggeredly distributed with some liquid injection holes 2 on the sidewall of said cone 4 and connected catheter body 1, the porose medicated cap 3 of all corresponding covering on the outer wall of each liquid injection hole 2 pairing catheter body 1, limit fluid can only flow to outside the catheter body 1 in catheter body 1.And described hole medicated cap 3 is laminar, and mutually bonding with the outer wall of catheter body 1 in the side near catheter body front end 4, and the material of catheter body 1 and hole medicated cap 3 is medical rubber hose; In addition, the axis of said liquid injection hole 2 all favours the axis of catheter body 1, and the tail end of the equal conductive pipe body 1 of the port of export tilts.Adopt above-mentioned technical scheme, when injection, under the effect of medicinal liquid pressure, each hole medicated cap 3 opens, and medicinal liquid is flowed out from staggered liquid injection hole 2 smoothly, and the diffusion of medicinal liquid can be more even, is beneficial to the early recovery of diseased region; After medicinal liquid is totally lost; Automatically close under the effect of each hole medicated cap 3 fluid pressure outside pipe, thereby stop blood and other body fluid to get in the catheter lumen, avoid blockage phenomenon; Therefore need not the injecting heparin normal saline, the side effect of avoiding causing because of the multiple injection heparin-saline takes place.
