Embodiment 1

[0023] This embodiment is the most basic implementation.

[0024] This embodiment provides a disposable bladder irrigation device, such as figure 1 As shown, it includes a perfusion device main body 1, and a main lumen 2 is provided inside the perfusion device main body 1, and a fixed balloon 3 is provided at the insertion end of the perfusion device main body 1, and the fixed balloon 3 communicates with the main lumen 2, and the fixed ball A plurality of injection microholes 4 are evenly distributed on the outer wall of the capsule 3; the tail end of the main cavity 2 is provided with a liquid medicine injection port, and the liquid medicine injection port is connected with a three-way pipe 5, and the three-way pipe 5 includes a The first empty needle interface 6 and the second empty needle interface 7 connected to the main lumen 2 are provided with a swivel joint 9 at the intersection of the two empty needle interfaces There is a rotary switch 8, and changing the angle of t...

Embodiment 2

[0029] This embodiment is based on the whole content of embodiment 1, the difference is:

[0030] Further, the front end of the injector main body 1 is also provided with a fixed water bladder 10 wrapped outside the injector main body 1, the fixed water bladder 10 is a closed cavity, and the injector main body 1 is provided with a fixed water bladder pipeline 11 It communicates with the fixed water bag 10, the tail end of the fixed water bag pipeline 11 is led out from the side of the main body, and the end is provided with a connector 14 with a water injection valve, which is inserted into the fixed water bag 10 through the fixed water bag pipeline 11 Water filling is carried out, and the expansion of the fixed water bag 10 can play an anti-slip effect in the urinary catheter.

[0031] Further, the surface of the syringe main body 1 is provided with a scale line 13 showing the insertion depth of the syringe. When a part of the pipeline comes out, the medical personnel can ob...

Embodiment 3

[0033] This embodiment is based on the whole content of embodiment 2, the difference is:

[0034] Further, the main lumen 2 is provided with a one-hand clamp 12 , and the one-hand clamp 12 is located between the second empty needle port 7 and the connecting head 14 . The one-hand clip 12 can control the on-off of the pathway where the main lumen 2 is located, so as to prevent backflow or overflow of chemotherapy drugs.

Abstract

The invention discloses a disposable urinary bladder perfusion apparatus and belongs to the field of medical devices. The disposable urinary bladder perfusion apparatus comprises a perfusion apparatusbody, wherein a main pipe cavity is formed in the perfusion apparatus body, a fixed balloon is arranged at the inserting end of the perfusion apparatus body and communicates with the main pipe cavity, and a plurality of injection micropores are uniformly distributed on the outer wall of the fixed balloon; a liquid medicine injection port is formed in the tail end of the main pipe cavity and connected with a three-way pipe, the three-way pipe comprises a first empty needle port and a second empty needle port which communicate with the main pipe cavity, a rotary switch is arranged at the intersection position of the two empty needle ports, and connection and disconnection of the two empty needle ports can be controlled by changing the angle of the rotary switch. By means of the injection micropores in the fixed balloon, a liquid chemotherapeutic drug can be dispersed in the urinary bladder, so that the liquid chemotherapeutic drug makes full contact with the inner wall of the urinary bladder, the medication effect is improved, and the staying time of a patient in a hospital is shortened; and by means of the design of the three-way pipe, the occupational exposure risk to a medical worker due to secondary puncture in the same position is reduced.

Description

technical field [0001] The invention relates to a perfusion device, in particular to a disposable bladder perfusion device. Background technique [0002] Bladder tumor is a clinically common tumor of the urinary system, which is more likely to occur in middle-aged and elderly men. Benign prostatic hyperplasia is one of the most common diseases in elderly men. Transurethral resection of bladder tumor is a kind of surgery for bladder tumors with carcinoma in situ less than 5mm in diameter, outward carcinoma and inverted papillary carcinoma less than 5cm in diameter, and stage B1T2 invasive carcinoma. Bladder tumor resection combined with bladder infusion. Bladder infusion therapy refers to using a catheter to inject chemotherapy drugs into the bladder, keep it for a period of time, and then urinate. [0003] Therefore, the patient's close cooperation is required throughout the bladder perfusion process. Due to the particularity of the physiological anatomy of the male ureth...
