Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a urinary catheter pulling and fixing device. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. Medical devices include medical equipment and medical consumables. The effectiveness is mainly obtained through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role. The purpose is to diagnose, prevent, monitor, treat or alleviate diseases; diagnose, monitor, treat, alleviate or compensate for injuries; inspect, replace, regulate or support physiological structures or physiological processes; support or maintain life; control pregnancy; and provide information for medical or diagnostic purposes by examining samples from the human body.

[0003] When a patient undergoes prostatectomy, there is a certain gap between the bladder and the urethra, and the bladder and the urethra need to be sutured directly. However, due to the pulling force of the bladder to return to its original position, the suture growth effect usually cannot reach the expected effect. Therefore, a catheter is needed to hold the bladder. The catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) that can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the catheter head to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0004] Currently, when fixing the urethra of a patient with a urinary catheter, there are disadvantages such as cumbersome operation and unreliable fixation. In addition, the pulling force of the catheter cannot be detected. When the pulling force of the catheter is too large, the internal section of the catheter placed in the bladder is easily pulled out, and the catheter needs to be reinserted, which increases the burden on the patient. Excessive pulling force will also compress the internal tissues, which can easily cause pressure injuries or even scars. Utility Model Content

[0005] The purpose of the utility model is to provide a urinary catheter pulling and fixing device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A urinary catheter pulling and fixing device comprises a urinary catheter, wherein a fixed shell is movably connected to the side wall of the urinary catheter, the fixed shell comprises a bottom fixing seat and a top fixing belt, a plurality of support rods are fixedly connected to one side of the surface of the fixing belt, a rubber ball is fixedly connected to the top of the support rod, a plurality of positioning holes are opened on the other side of the fixing belt, a tension detection box is movably connected to the side wall of the urinary catheter, an alarm device is fixedly connected to the inside of the tension detection box, and a pressure sensor is fixedly connected to the connection between the inner wall of the tension detection box and the urinary catheter.

[0008] Preferably, the side wall of the urinary catheter is movably connected with a gauze piece.

[0009] Preferably, the entire material of the fixed shell is rubber, and a plurality of hollow holes are provided on the surface of the fixed belt.

[0010] Preferably, a bandage is movably connected to the side of the tension detection box, and the bandage is fixed to the inner side of the patient's thigh by crossing.

[0011] Preferably, a tension display screen is fixedly connected to the top of the tension detection box, and the pressure sensor is connected to the tension display screen and the alarm device.

[0012] Preferably, the radius of the rubber ball is smaller than the radius of the positioning hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This catheter pulling and fixing device fixes the catheter on the patient through a fixed shell, by pressing the fixing seat against the patient's glans penis, and by buckling the rubber ball into a suitable positioning hole, so that the fixing belt fixes the glans penis on the catheter in a relatively comfortable manner, so that the catheter is firmly fixed and the catheter balloon can continuously and stably press on the wound surface to stop bleeding.

[0015] 2. This catheter pulling and fixing device is equipped with a tension detection box, an alarm device and a pressure sensor. When in use, the pressure received by the catheter is transmitted to the alarm device through the pressure sensor. When the alarm device detects that the tension transmitted by the pressure sensor is too large or too small, the alarm device sends an alarm to remind patients and medical staff to prevent the catheter from being unable to stretch the bladder as it should due to excessive or insufficient tension, thereby reducing the tension of the anastomosis and promoting wound healing.
