Embodiment 1

[0031] according to Figure 1 to Figure 2As shown, a bladder cancer chemotherapy 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 bidirectional urine and flushing agents. Corrosion; the outer wall of the catheter 10 is formed with a catheter hole 102 connected to the catheter 10 near the front end for the 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 is formed for directly administering medicine to the inner wall of the bladder; the outer wall of the urinary catheter 10 is formed with an elastic support bag 11 between the urinary catheter hole 102 and the drug delivery hole 104 ; the support bag 11 The middle of the outer periphery is formed with an elastic dividing ring 13 that can be pressed against the inner wall of the bladder; the outer wall of the urinary...

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 bag 11 is uniformly formed with a plurality of elastic liquid-blocking rings 14 that can abut against the inner wall of the bladder at the front of the separating ring 13 ; The outer wall of the urinary catheter 10 is formed with a plurality of liquid blocking injection tubes 109 that are connected with the corresponding liquid blocking ring 14 and the same as the injection tube 105; A liquid blocking tube that communicates with the corresponding liquid blocking ring 14 and the corresponding liquid blocking injection pipe 109 .

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

Abstract

The invention discloses a bladder cancer chemotherapy drug injector, which comprises a urinary catheter; a urinary catheter hole is formed on the outer wall of the urinary catheter near the front end; A support bag is formed on the outer wall between the catheterization hole and the drug delivery 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 near the rear end; when the support bag and the separation ring are injected with gas, the separation ring is formed. The ring is inflated to abut against the inner wall of the bladder, and the dividing ring divides the bladder into two cavities that are not connected with each other, so that the medication area and the urination area are isolated. The invention can make the urine flowing out of the ureteral orifice to be directly discharged from the body through the catheter, so as to prevent the urine from causing dilution and pollution to the medicine; the medicine can directly reach the inner wall of the bladder, which is beneficial to the absorption of the medicine at the affected part; The urinary catheter is prevented from accidentally slipping out of the body; a separating ring is provided, which can isolate the medicine and the urine, and prevent the medicine from being diluted and polluted by the urine.

Description

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