Description

Technical Field

[0001] The utility model relates to the field of medical nursing equipment, in particular to a urinary catheterization device used for obstetric nursing. Background Art

[0002] In obstetric care, it involves catheterization for women with urinary retention. The steps of catheterization include:

[0003] 1. Expose the urethra: The patient lies supine with the knees bent and legs extended to fully expose the urethra.

[0004] 2. First disinfection: Use a cotton ball dipped in mucosal disinfectant to disinfect the mother's thighs, vulva and urethra;

[0005] 3. Secondary disinfection: disinfect the maternal vulva and urethra again;

[0006] 4. Inserting a urinary catheter: Apply sterile lubricant to the catheter to reduce friction and relieve pain. Separate the labia minora to expose the urethral opening, and slowly insert the catheter into the urethra. The insertion length is about 6-8 cm. After seeing urine flow out, continue to insert it 2-3 cm. Inject 10-15 ml of sterile saline into the balloon on the catheter. Gently push the catheter. If moderate resistance is felt, it confirms that the catheter is fixed.

[0007] In clinical catheterization care, there are the following technical problems:

[0008] 1. When the first catheterization produces 600-700ml of urine, the catheter needs to be clamped to prevent bleeding caused by emptying the catheter. Currently, medical staff observe and manually clamp the catheter when the urine output reaches 600-700ml. After a period of clamping, the catheter is opened again for a second catheterization. This entire process takes up a considerable amount of time and workload for medical staff.

[0009] 2. When the patient gets out of bed, the catheter bag is not easy to fix; in addition, since the material of the catheter bag is relatively soft, the catheter bag is easily squeezed or hooked when the patient gets out of bed.

[0010] 3. After the catheter bag is filled with urine, the patient or family member needs to urinate. In actual clinical practice, it often happens that the patient does not realize that the urine bag is full in time and does not urinate in time. Utility Model Content

[0011] The utility model aims to provide a urinary catheterization device for obstetric care, so as to solve the problem that the use of the existing urinary catheterization device causes a heavy workload for medical staff.

[0012] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] A urinary catheterization device for obstetric care includes a urinary catheter bag and a urinary catheter, which is detachably connected to the urinary catheter bag. The device also includes a controller and a hard, transparent protective cover. The protective cover is used to place the urinary catheter bag, has a sealed bottom and an open top, and is provided with a clamping position liquid level sensor on the inner wall of the protective cover. The position height of the clamping position liquid level sensor is consistent with the liquid level of urine in the urinary catheter bag when the urinary catheter needs to be clamped. The clamping position liquid level sensor is electrically connected to the controller, and the controller is electrically connected to a clamping valve. A first strap is connected to one side of the protective cover and a second strap is connected to the other side. The first strap and the second strap are detachably connected.

[0014] Preferably, as an improvement, the number of the clamping position liquid level sensors is at least three, and the three clamping position liquid level sensors are all arranged on the same horizontal plane of the protective cover.

[0015] Preferably, as an improvement, a through hole is provided at the bottom of the protective cover for the drainage tube of the catheter bag to pass through, and a urine level sensor is also provided on the inner wall of the top of the protective cover. The urine level sensor is electrically connected to the controller, and the controller is electrically connected to the alarm.

[0016] Preferably, as an improvement, the number of the urination liquid level sensors is at least three, and the three urination liquid level sensors are all arranged on the same horizontal plane of the protective cover.

[0017] Preferably, as an improvement, the outer side surface of the first strap is sewn with a suede surface of the Velcro, and the inner side surface of the second strap is sewn with a hook surface of the Velcro.

[0018] Preferably, as an improvement, inserts are provided in the free ends of the first and second binding straps.

[0019] Preferably, as an improvement, an arc-shaped groove is provided on one side of the protective cover.

[0020] The principles and beneficial effects of this program are:

[0021] 1. This solution sets up a protective cover and places the catheter bag inside the protective cover. When the discharged urine rises to the clamping position liquid level sensor, the clamping position liquid level sensor sends a clamping signal to the controller. The controller controls the clamping valve to clamp the catheter for a period of time. After the clamping time is up, the catheter is opened and catheterization is continued. This solution can realize the automatic clamping and opening of the catheter, reducing the workload and work burden of medical staff.

[0022] 2. In addition, this solution also sets a urination level sensor on the top of the protective cover. When the catheter bag is filled with urine, the urination level sensor sends a urination signal to the controller. The controller controls the alarm to remind the patient and the patient's family to urinate, which can effectively avoid the problem of patients and their families forgetting to urinate.

[0023] 3. Building on the above, this solution incorporates at least three clamping level sensors. The controller averages the values ​​of these sensors, achieving higher accuracy and effectively preventing level errors caused by catheter bag tilt, allowing for timely closure of the catheter when necessary. Similarly, the addition of multiple urination level sensors can also improve urination level accuracy.

[0024] 4. This solution incorporates a transparent, hard protective cover, which not only facilitates viewing of the urine within the catheter bag but also protects the bag from being squeezed or snagged when the patient moves out of bed. Furthermore, electrical components such as the controller and clamping level sensor are housed within the protective cover, eliminating the need to modify the catheter bag structure and allowing for reuse, saving equipment costs.

[0025] 5. This solution provides a first strap and a second strap. When the patient gets out of bed, the protective cover is fixed to the patient's legs through the first strap and the second strap, which is convenient for carrying the catheter bag. When the patient is lying in bed, the protective cover can also be tied to the bed through the first strap and the second strap, thereby fixing the catheter bag to the bed. When fixing, the first strap and the second strap are inserted between the bed and the bed frame and then passed out, and the first strap and the second strap are tied to the bed frame. This solution provides inserts at the free ends of the first strap and the second strap, which are convenient for inserting the first strap and the second strap from between the bed and the bed frame, making it more convenient to tie.

[0026] 6. The first and second straps are detachably connected via Velcro, allowing for easy adjustment of tightness based on patient size, making it suitable for patients of varying body shapes. A curved groove is provided on one side of the protective cover, which fits the patient's leg better, improving its stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 This is a schematic structural diagram of Example 1 of the present utility model.

[0028] Figure 2 This is a structural diagram of Example 2 of the present utility model. DETAILED DESCRIPTION

[0029] The following is further described in detail through specific implementation methods:

[0030] The reference numerals in the drawings of the specification include: urinary catheter 1, clamping valve 11, urine catheter bag 2, urination tube 21, protective cover 3, urination position liquid level sensor 31, clamping position liquid level sensor 32, first strap 33, velvet 34, second strap 35, and insert 36.

[0031] Example 1:

[0032] like Figure 1As shown, a urinary catheterization device for obstetric care includes a urinary catheter bag 2, a urinary catheter tube 1, a protective cover 3, and a controller, which is a single-chip microcomputer or a programmable logic controller (PLC). The urinary catheter bag 2 is conventionally used, and the urinary catheter tube 1 is equipped with a pinch valve 11, which is electrically connected to the controller. The urinary catheter 1 and the urinary catheter bag 2 are detachably connected. This is conventional technology and will not be described in detail here.

[0033] The protective cover 3 is hard, transparent, and lightweight, and can be made of plastic or hard rubber. The bottom of the protective cover 3 is sealed and the top is open. The protective cover 3 is used to place the urine catheter bag 2. The bottom of the protective cover 3 is provided with a through hole for the urine drainage tube 21 of the urine catheter bag 2 to pass through. At least three clamping position liquid level sensors 32 are installed on the inner wall of the protective cover 3. In this embodiment, the number of clamping position liquid level sensors is four, and the four clamping position liquid level sensors 32 are all arranged on the same horizontal plane of the protective cover 3. The installation height of the clamping position liquid level sensor 32 is set according to the urine level in the urine catheter bag 2 when clamped. In this embodiment, it is set at a urine level of 600ml. At least three urination position liquid level sensors 31 are also installed on the inner wall of the top of the protective cover 3. In this embodiment, the number of urination position liquid level sensors 31 is four, and the four urination position liquid level sensors 31 are also all arranged on the same horizontal plane of the protective cover 3. The clamping position liquid level sensor 32 and the urination position liquid level sensor 31 are both electrically connected to the controller, and the controller is electrically connected to an alarm.

[0034] A first strap 33 is glued to one side of the protective cover 3, and a second strap 35 is glued to the other side. The first strap 33 and the second strap 35 are detachably connected via Velcro. The outer side of the first strap 33 is sewn with a Velcro suede surface 34, and the inner side of the second strap 35 is sewn with a Velcro hook surface.

[0035] In actual use, after the urinary catheter 1 is inserted and connected to the catheter bag 2, the bag 2 is placed in the protective cover 3. The clamping level sensor 32, the urination level sensor 31, the controller, and the alarm are activated. When urine rises to the clamping level sensor 32, the four clamping level sensors 32 detect urine data and send a clamping signal to the controller. The controller analyzes the urine data and takes the average value of the four clamping level sensors 32. When the average value reaches 600ml±50ml, the controller controls the clamping valve 11 to clamp the urinary catheter 1, achieving automatic clamping. When the urine is full, the urination level sensor 31 detects urine and sends a urination signal to the controller, which controls the alarm to sound, reminding the patient or family member to urinate.

[0036] After the urine catheter bag 2 is placed in the protective cover 3, if the patient needs to stay in bed, the protective cover 3 is secured to the bed frame using the first and second straps 33, 35. If the patient needs to get out of bed, the protective cover 3 is secured to the patient's legs using the first and second straps 33, 35. The protective cover 3 effectively protects the urine catheter bag 2 from being squeezed or snagged. The transparent, lightweight protective cover 3 used in this solution not only facilitates urine observation but also makes it easy for the patient to carry when getting out of bed.

[0037] Example 2:

[0038] like Figure 2 As shown, this embodiment differs from Embodiment 1 in that a hard insert 36 is sewn into the free ends of the first and second straps 33, 35. The insert 36 is made of plastic, metal, or the like. The insert 36 increases the hardness of the ends of the first and second straps 33, 35, making it easier to insert the straps between the bed and the bed frame, thereby facilitating the binding of the first and second straps 33, 35 to the bed.

[0039] Example 3:

[0040] The difference between this embodiment and embodiment 2 is that an arc-shaped groove is provided on one side of the protective cover 3, so that the protective cover 3 can fit the patient's legs more closely, thereby improving the stability and comfort of the protective cover 3 tied to the legs.

[0041] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
