Description

Simple bladder negative pressure drainage device

technical field

The utility model relates to a medical device, in particular to a simple and convenient bladder negative pressure drainage device.

Background technique

Intravesical bleeding is common in patients with urinary system injury after urological surgery, and also in patients with bladder tumors. For such patients, indwelling catheter drainage or even cystocentesis is an essential treatment. However, bleeding from any source in the urinary system accumulates in the bladder, and blood clots in the bladder will soon form. The jelly-like blood clots can easily block the drainage tube, resulting in poor drainage.

The Chinese patent No. 201120122999.9 discloses a bladder negative pressure flushing device, which includes a catheter, a drainage tube, a flushing tube, and a three-way valve connected to the catheter, drainage tube, and flushing tube. The port of the flushing tube is inserted into a flushing bottle , the port of the drainage tube is inserted and connected to the urine bottle, the flushing bottle is provided with an inflator, the inflation device is inserted into the flushing bottle through a catheter connection, the urine bottle is provided with an air suction device, and the air suction device is inserted into the urine container through the catheter connection. The bladder negative pressure flushing device is convenient to use and simple to operate, can eliminate the operation steps of repeatedly inserting and pulling out the catheter, avoids iatrogenic cross-infection, and can remove blood clots in the bladder.

The Chinese patent No. 200820184621.X discloses a positive and negative pressure closed bladder irrigator, which consists of a flushing bottle, a flushing tube, a "Y"-shaped connecting tube, a drainage tube, a catheter, a urine bottle, and a control clip. One end of the flushing tube and drainage tube is respectively connected to the glass tube and then inserted into the flushing bottle and the urine bottle, the other end is connected to the "Y"-shaped connecting pipe, the urinary catheter is connected to the "Y"-shaped connecting pipe, and the control clips are respectively set on the "Y"-shaped connecting pipe. The flushing pipe and the drainage pipe, and the flushing bottle and the urine bottle are provided with a suction device. The positive and negative pressure closed bladder irrigator has the advantages of strong adaptability, convenient operation, clean rinsing and less infection.

The structure of the above patents is comparatively complicated, and the cost of use is high. It needs to be disinfected every time it is used, and the operation is inconvenient. It needs further improvement and improvement.

Utility model content

The purpose of the utility model is to overcome the above-mentioned defects of the prior art and provide a simple bladder negative pressure drainage device with simple structure and convenient operation.

In order to achieve the above object, the technical solution provided by the utility model is as follows: a simple bladder negative pressure drainage device, including a catheter, the catheter is sealed and connected to the front end of the negative pressure device connecting tube through the connector, and the negative pressure device connecting tube The rear end is sealed and connected with the main connector provided on the top of the negative pressure device, and the top of the negative pressure device is provided with a spare connector.

The negative pressure device is a disposable medical negative pressure device, which is a folded and compressed airtight container.

The spare connector of the negative pressure device is sealed and connected with the medical negative pressure central equipment.

The urinary catheter is a flushing three-chamber urinary catheter, the outlet end of the catheter is on the side, where the first chamber is connected to the flushing port with a first sealing cover, and the second chamber on the side is connected to the airbag inflation port with a second sealing cover .

The spare connector of the negative pressure device is provided with a sealing cover.

The main connector of the negative pressure device is connected with a flexible pipe, and a switching valve is arranged on the flexible pipe.

The utility model is beneficial in that the structure is simple, the operation is convenient, the iatrogenic cross-infection of the patient is reduced, and it is especially beneficial to the recanalization and drainage after the bladder blood clot or urine sediment blocks the urethra after the operation.

Description of drawings

Fig. 1 is a three-dimensional schematic diagram of a simple bladder negative pressure drainage device of the present invention.

Detailed ways

The technical solution of the utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.

As shown in Figure 1, a simple bladder negative pressure drainage device includes a catheter 1, the catheter 1 is sealed and connected to the front end 31 of the connecting tube 3 of the negative pressure device through the connector 2, and the rear end of the connecting tube 3 of the negative pressure device is sealed. 32 is airtightly connected with the main connector 41 provided at the top of the negative pressure device 4, and the top of the negative pressure device 4 is provided with a spare connector 42.

The negative pressure device 4 is a disposable medical negative pressure device, which is a folded and compressed airtight container.

The spare connector 42 of the negative pressure device 4 is in sealing connection with the medical negative pressure central equipment (not shown in the figure).

One end of the urinary catheter 1 is provided with a first shunt tube 11 and a second shunt tube 12 , and the first shunt tube 11 and the second shunt tube 12 are respectively provided with a first sealing cover 13 and a first sealing cover 14 .

The urinary catheter 1 is a flushing three-chamber urinary catheter, the outlet end of the catheter 1 is on the side, wherein the first chamber is connected to the flushing port 11, the second chamber on the side is connected to the air bag inflation port 12, and the first chamber is connected to the flushing port 11. A first sealing cover 13 is provided, and a second sealing cover 14 is provided on the side of the second chamber connected to the air bag inflation port 12 .

The spare connector 42 of the negative pressure device 4 is provided with a third sealing cover 43 .

A hose 44 is connected to the main connector of the negative pressure device 4, and a switch valve 45 is installed on the hose 44.

The working principle of the utility model is: insert the urinary catheter 1 into the bladder of the patient, open the negative pressure device 4, and use the negative pressure siphon effect generated when the negative pressure device 4 expands to remove the small blood clot or a small amount of urine in the patient's bladder. Sediment sucking, small blood clots or a small amount of urine sediment are sucked into the negative pressure device 4 and discharged through the catheter 1. Since the negative pressure device 4 only has a negative pressure of 1.6kPa, only small blood clots or a small amount of urine sediment can be sucked out. Blood clots and sediment need to be connected to the negative pressure equipment of the hospital medical center through the negative pressure device 4 with the connector 42. When it reaches about 26.66kPa, the large blood clot or urine sediment in the bladder can be sucked out, avoiding the need for patients to Surgical trauma or risk associated with removal of blood clots or urine sediment through cystostomy or cystoscopic surgery. Wherein, when pouring the urine, the negative pressure device 4 needs to be turned upside down, and the urine should be squeezed out if necessary. In order to avoid the reflux of the urine, the switch valve 45 needs to be closed to avoid retrograde infection.

What has been described above is only the principle and preferred embodiments of the present utility model. It should be pointed out that those skilled in the art can make some modifications and improvements without departing from the principle of the utility model, which should also be regarded as belonging to the protection scope of the utility model.
