Embodiment 1

[0031] according to Figure 1 to Figure 2As shown, a bladder cancer chemotherapeutic drug injector described in this embodiment includes a urinary catheter 10; the urinary catheter 10 is made of corrosion-resistant medical silicone material, and is resistant to two-way flow of urine and flushing agents. Corrosion; the outer wall of the urinary catheter 10 is formed near the front end with a catheter hole 102 communicating with the catheter 10 to allow urine to flow out of the bladder; the outer wall of the catheter 10 is located in front of the catheter hole 102 A drug delivery hole 104 for direct medication to the inner wall of the bladder is formed; an elastic support bag 11 is formed on the outer wall of the catheter 10 between the catheter hole 102 and the drug delivery hole 104; the support bag 11 The middle part of the periphery is formed with an elastic partition ring 13 that can be pressed against the inner wall of the bladder; the outer wall of the catheter 10 is form...

Embodiment 2

[0056] according to image 3 As shown, this embodiment makes the following improvements on the basis of embodiment 1: the outer periphery of the support bladder 11 is located at the front of the partition ring 13 and is evenly formed with a plurality of elastic liquid blocking rings 14 that can be pressed against the inner wall of the bladder The outer wall of the catheter 10 is formed near the rear end with a plurality of liquid-blocking injection tubes 109 that communicate with the corresponding liquid-blocking ring 14 and are identical to the injection tube 105; A liquid blocking tube communicating with the corresponding liquid blocking ring 14 and the corresponding liquid blocking injection pipe 109 .

[0057] During treatment, most of the therapeutic drugs used will cause some damage to the inner wall of the bladder without lesions, which will have a certain impact on the rehabilitation of later users, shorten the recovery time, and aggravate the side effects of the drugs...

Abstract

The invention discloses a bladder cancer chemotherapeutic drug injector. The bladder cancer chemotherapeutic drug injector comprises a catheter, a catheterization hole is formed in the outer wall of the catheter close to the front end; a dosing hole is formed in the outer wall of the catheter and in front of the catheterization hole; a support bag is formed on the outer wall of the catheter between the catheterization hole and the dosing hole; a separation ring is formed on the periphery of the support bag; a plurality of injection tubes are formed on the outer wall of the catheter close to the rear end; when gas is injected into the support bag and the separation ring, the separation ring expands to abut against the inner wall of the bladder and divides the bladder into two cavities which are not communicated with each other, so that the medication area and the urination area are isolated. The urine flowing out of the ureter opening can be directly discharged out of the body through the catheter, and dilution and pollution of the urine to medicine are prevented; medicine can directly reach the inner wall of the bladder, and medicine absorption of an affected part is facilitated; an anti-falling bag is arranged, so that the catheter can be prevented from accidentally sliding out of the body; the separation ring is arranged, so that medicine and urine can be isolated, and the medicine is prevented from being diluted and polluted by the urine.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bladder cancer chemotherapeutic drug injector. Background technique [0002] The Chinese patent document with the document number CN109498969A discloses a drug delivery catheter, including a catheter body and a drug delivery pipeline, the catheter body includes a urine outlet, and a catheter is connected to the outlet tube, the urinary catheter is connected with a urine inlet, the inner side of the catheter is provided with a flushing tube, the flushing pipe is connected with a drug inlet, and the drug inlet is connected with an adjustment head, so The middle part of the urinary catheter is connected with a medicine bag, and the wall of the medicine bag is provided with a medicine outlet hole, and the array of the medicine outlet holes is distributed on the wall of the medicine bag, and the end of the medicine bag is connected with a syringe. A connector, t...
