Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical treatment, and particularly relates to a urinary catheterization device for urology. BACKGROUND

[0002] Catheterization refers to inserting a catheter into the bladder through the urethra to drain urine. Catheterization is divided into two types: catheter retention catheterization and intermittent catheterization. The former type of catheterization is to keep the catheter in the patient's body at all times, and the catheter is removed or replaced with a new one when the patient's condition permits. The latter type of catheterization is to catheterize the patient every hour, and the catheter is removed after the bladder is emptied. The catheter should not be reused, otherwise the user may be infected with bacteria.

[0003] The existing technology has the following disadvantages: During the use of the catheterization device, the urine in the urine bag body needs to be discharged according to the amount of urine of the patient. The urine is usually discharged several times a day. Generally, the discharge pipe of the urine bag is opened, and then the urine in the urine bag body is naturally discharged. The efficiency of urination is slow, and the urination is not complete.

[0004] According to the search, application No. 202510660643.7 discloses a urinary catheterization device for urology, which comprises a shell, a positioning rod is arranged in the shell, a urine bag body is mounted on the circumferential surface of the positioning rod through a ring buckle, an input connector and an output connector are mounted in the shell, the urine bag body is connected with the input connector through an input pipe, the urine bag body is connected with the output connector through an output pipe, the input connector is connected with a catheter through a connecting pipe, mounting plates are mounted in the shell, first guide grooves are formed on the surfaces of the mounting plates, rotating rods are slidingly connected in the first guide grooves, squeezing rollers are rotatingly connected on the circumferential surface of the rotating rods, a first sliding block is slidingly connected in the shell, an active groove is formed in the first sliding block, and both ends of the rotating rod are located in the active groove. The urine in the urine bag body is fully discharged under the action of the squeezing assembly, the discharge speed of the urine is improved, and the use experience of the patient is improved.

[0005] However, the urine bag body in the device is arranged in the interior of the shell, and the staff cannot accurately observe the amount of urine in the interior of the urine bag body. The amount of urine of the patient is generally directly related to the amount of water drunk and the food eaten by the patient in a day. If the urine is still discharged in a timed manner, if the amount of water drunk by the patient in a day is large, the urine in the urine bag body may overflow and backflow may occur. If the amount of water drunk by the patient in a day is small, the amount of urine of the patient will be less, and the urine in the urine bag body will be less, which will increase the unnecessary labor intensity of the staff.

[0019] The beneficial effects of the present application are: 1. The observation piece in the device can facilitate the staff to observe the urine amount in the urine bag. If the urine amount in the urine bag is large, the urine in the urine bag can be discharged in time. If the urine amount in the urine bag is small, the discharge can be selected according to the need, thereby greatly reducing the labor intensity of the staff.

[0020] 2. The protective plate of the device can protect the placing piece, thereby ensuring the safety of the placing piece during work.

[0021] 3. The placing groove on the vertical plate of the device can facilitate the placing of the urine bag, and the fixing piece in the placing groove can facilitate the clamping and fixing of the two sides of the urine bag, thereby ensuring the safety and stability of the urine bag during work.

[0022] 4. The observation piece of the device can facilitate the staff to observe the urine amount in the urine bag. The floating plate can facilitate the upward movement of the connecting rod and the rotating arm along with the urine amount, thereby facilitating the observation of the staff. When the urine in the urine bag increases, the urine bag will expand to both sides, thereby driving the floating plate, the connecting rod and the rotating arm to move upward along the adjusting hole and the first slot, thereby facilitating the staff to judge the urine amount in the urine bag according to the position of the holding rod.

[0023] 5. When the urine needs to be discharged, the holding rod is gripped to drive the rotating arm to rotate around the fixed shaft. In the process of rotating the rotating arm, the sliding block will slide along the sliding groove on the floating plate. At the same time, the included angle between the rotating arm and the floating plate will increase. In the process of rotating the rotating arm, the swing rod will rotate around the rotating shaft. The rotating of the rotating arm will drive the rotating rod to rotate. The rotating of the rotating rod will drive the extrusion rollers on the floating plates on both sides of the vertical plate to move towards the middle. When the extrusion rollers on the floating plates on both sides of the vertical plate contact each other, the holding rod is pulled to drive the floating plate and the extrusion rollers to move downward, thereby discharging the urine from the urine bag.

[0024] 6) The limiting component of this device is used to fix the upright plate inside the first fixing groove, ensuring that the urine bag is always in a stable state during operation. Pushing the bottom plate will cause the upright plate to move upward. When the top of the upright plate contacts the inclined surface of the limiting block, continuing to push the upright plate upward will push the second rack to move outward until the limiting hole contacts the limiting block. When the limiting hole contacts the limiting block, the second rack will be driven into the limiting hole under the action of the second spring, thus achieving the purpose of limiting the upright plate.

[0025] 7) The corrugated sleeve of this device can protect the first rack and ensure its safety during operation. The first guide groove and the first guide block ensure the safety and stability of the first rack during operation and prevent it from shaking. The second guide groove and the second guide block can ensure the safety and stability of the second rack during operation.

[0026] 8) The flow-stopping device can clamp and block the urination tube to prevent urine from being discharged from the urination tube when not urinating. By turning the knob, the rotating shaft is driven to rotate, which in turn drives the threaded rod to rotate. The rotation of the threaded rod will drive the first clamping plate and the second clamping plate to move towards the center until the urination tube is clamped.

[0027] 9) The fixing parts of this device are used to fix the two upper corners of the urine bag, ensuring that the urine bag is always in a stable state during operation. By controlling the handle, the lower pressure rod moves towards the tray until the pressure plate is placed in the second limiting groove at the top of the tray, thereby fixing the urine bag on the tray. The setting of the limiting rod and the slot can limit the pressure shaft, ensuring the normal operation of the pressure shaft.

[0028] 10) The locking mechanism of this device can restrict the grip bar and ensure that the grip bar is always in a stable state during operation. The third spring is used to provide upward stress to the locking block so that the locking block always cooperates with the grip bar. Attached Figure Description
