Description

Technical Field

[0001] This utility model relates to the field of nursing device technology, specifically a peritoneal puncture hole anti-leakage pressure measuring device. Background Technology

[0002] Paracentesis is widely used in clinical diagnosis and treatment, covering important scenarios such as drainage of ascites, monitoring of intra-abdominal pressure, and decompression after laparoscopy. However, current traditional methods of closure of the puncture site have many drawbacks, mainly relying on sutures or dressing compression, and cannot dynamically adapt to changes in intra-abdominal pressure. In pathological conditions with increased intra-abdominal pressure, such as abdominal compartment syndrome and intestinal obstruction, the puncture site is highly susceptible to leakage, air leakage, and even organ prolapse, significantly increasing the risk of infection. Literature indicates that leakage-related infection rates reach 12%-18%.

[0003] Existing pressurization devices mostly employ a fixed pressure mode, lacking a real-time pressure feedback mechanism. This leads to problems in practical applications: either excessive pressure causes local tissue ischemia, or insufficient pressure fails to effectively prevent leakage. In terms of intra-abdominal pressure monitoring, indirect methods such as cystometry are mainly used clinically. These methods are complex, requiring catheterization and water injection, and exhibit measurement lag, with intervals exceeding 30 minutes, making them unsuitable for continuous dynamic monitoring. While direct puncture pressure measurement offers higher accuracy, it requires repeated punctures, significantly increasing the risk of trauma; studies show a complication rate as high as 9.3% with repeated punctures. The Winter Chamber Syndrome Association (WSACS) guidelines also clearly state that current technologies cannot meet the urgent need for real-time pressure monitoring in critically ill patients.

[0004] In addition, there are problems with uncontrollable pressure during clinical operation. The tightness of gauze pressure depends too much on the operator's experience, which can easily lead to insufficient pressure causing continuous leakage, or excessive pressure causing skin ischemia. When the amount of ascites leakage is large, the dressing will be repeatedly soaked and needs to be changed frequently, increasing the workload of medical staff. When the patient's position changes or moves, the existing device is not stable and is prone to displacement. In order to check the wound condition, the dressing needs to be opened repeatedly, which further increases the risk of infection.

[0005] Therefore, those skilled in the art have provided a device for preventing leakage and measuring pressure at the abdominal puncture site to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a device for preventing leakage and measuring pressure in abdominal puncture holes, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An abdominal puncture site leak-proof pressure measuring device includes a base layer. An observation window, a circular transparent observation area with a graduated ring, is centrally located at the upper end of the base layer. A circular pressure cylinder is fixedly connected to the upper end of the base layer, located outside the observation window. A graduated line is formed at the top outer edge of the pressure cylinder. A threaded groove is formed at the top of the pressure cylinder, and a through groove extending to the threaded groove is formed at the bottom of the pressure cylinder. A knob is threaded into the threaded groove. Six compression springs are arranged in a ring at the bottom of the threaded groove. A top plate is formed on top of the six compression springs, and a circular pressure plate, made of silicone, is fixedly connected to the lower end of the top plate.

[0009] As a further embodiment of this utility model: an outer sliding cavity is provided on both outer walls of the pressure cylinder, and an inner sliding cavity is provided on the inner wall of the threaded groove at the opposite position, and a through hole is provided between the outer sliding cavity and the inner sliding cavity.

[0012] As a further improvement of this utility model: a miniature pressure sensor is embedded in the bottom of the pressure plate, and a through hole is opened on the side wall of the pressure cylinder corresponding to the position of the miniature pressure sensor. The miniature pressure sensor is electrically connected to a digital display head through the through hole.

[0013] As a further improvement of this utility model: two fixed wings are provided on both sides of the base layer. The fixed wings extend from both sides of the base layer, have air vents and are adhesive.

[0014] As a further improvement of this utility model: the base layer is a medical-grade transparent polyurethane film with a thickness of 0.5-1.0 mm, and one side is provided with a breathable and low-allergenic adhesive layer for adhering to the skin and covering the puncture hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the cooperation of the knob and the threaded groove of the pressure cylinder, can precisely control the raising and lowering of the pressure plate, achieving fine adjustment of the puncture hole pressure; the miniature pressure sensor monitors the pressure in real time and displays it intuitively through the digital display, making it easy for medical staff to accurately grasp the pressure data and effectively avoid the problem of tissue damage due to excessive pressure or leakage caused by insufficient pressure; the six compression springs at the bottom of the threaded groove cooperate with the top plate to provide a certain buffer when the pressure plate applies pressure, ensuring stable pressure output; the locking structure composed of the lock head, telescopic spring, guide plate and other components between the knob and the pressure cylinder can prevent the knob from rotating due to accidental contact during use, ensuring the stability of the pressure setting and further improving the safety of use.

[0017] 2. The circular transparent observation window and graduated ring on the base layer allow medical staff to directly observe the puncture site and quantify the extent of exudation through the graduated ring, providing a direct basis for assessing the patient's condition and adjusting the treatment plan, thus improving nursing efficiency and accuracy.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Reference Figures 1-5 This embodiment provides a peritoneal puncture site leakage monitoring device, including a base layer 1. An observation window 6 is centrally located at the upper end of the base layer 1. The observation window 6 is a circular, transparent observation area and includes a graduated ring 7. The graduated ring 7 can be used to assess the leakage range, facilitating direct assessment of the leakage situation by medical personnel. A circular pressure cylinder 2 is fixedly connected to the upper end of the base layer 1. The pressure cylinder 2 is located outside the observation window 6. A graduation line 5 is provided at the top outer edge of the pressure cylinder 2. A threaded groove 9 is provided at the top of the pressure cylinder 2, and a through-thread groove is provided at the bottom of the pressure cylinder 2. The groove 10 of the groove 9 has a knob 3 internally threadedly connected to it. Six compression springs 13 are arranged in a ring at the bottom of the groove 9. A top plate 11 is provided on the top of the six compression springs 13. A circular pressure plate 12 is fixedly connected to the lower end of the top plate 11. The pressure plate 12 is made of silicone. The pressure plate 12 is linked with the knob 3 and can move up and down axially as the knob 3 rotates. When the rotary button 20 is rotated, the pressure plate 12 moves downward and applies linear pressure to the puncture hole through the elastic deformation of the silicone plate, thereby effectively compressing the tissue around the puncture hole and closing the potential leakage channel.

[0027] Example 2

[0028] Reference Figures 1-5This embodiment is based on the previous embodiment, but differs in that: outer sliding cavities 17 are formed on both outer walls of the pressure cylinder 2, and inner sliding cavities 18 are formed on the inner wall of the threaded groove 9 at opposite positions; a through hole 19 is formed between the outer sliding cavities 17 and the inner sliding cavities 18; a button 20 is slidably connected inside the outer sliding cavity 17, and a guide plate 22 is slidably connected inside the inner sliding cavity 18; the guide plate 22 and the button 20 are fixedly connected by a guide rod 21, and the guide rod 21 is slidably connected to the inner wall of the through hole 19; a telescopic cavity 14 adapted to the inner sliding cavity 18 is formed on the outer wall of the knob 3, and a telescopic spring 15 is provided on the bottom wall of the telescopic cavity 14. A lock head 16 is fixedly connected to the front end of the spring 15; a miniature pressure sensor is embedded in the bottom of the pressure plate 12, and a through hole 8 is opened on the side wall of the pressure cylinder 2 corresponding to the position of the miniature pressure sensor. The miniature pressure sensor is electrically connected to a digital display head 4 through the through hole 8. The miniature pressure sensor is a piezoresistive sensor with a range of 0-60 mmHg and an accuracy of ±1 mmHg. It is used to detect the pressure of the tissue around the puncture site in real time and convert the pressure signal into an electrical signal. The digital display head 4 is integrated on the outside of the transparent base and is an LCD display screen. It is electrically connected to the miniature pressure sensor and can display the current pressure value and historical trend curve in real time, so that medical staff can intuitively understand the pressure changes.

[0029] Furthermore, two fixing wings 23 are provided on both sides of the base layer 1. The fixing wings 23 extend from both sides of the base layer 1, have air vents and are adhesive, reducing patient skin discomfort and enhancing the stability of the device on the patient's skin to prevent the device from shifting. The base layer 1 is a medical-grade transparent polyurethane film with a thickness of 0.5-1.0 mm. One side is provided with an air-permeable and low-allergenic adhesive layer for adhering to the skin and covering the puncture hole.

[0030] Working principle: First, ensure knob 3 is in the initial position according to scale line 5. At this time, the digital display 4 will be zero. Disinfect the skin around the puncture site with a regular disinfectant and wipe the surface liquid dry with sterile gauze. Carefully peel off the backing paper of the transparent base and accurately align the center of the observation window 6 of the transparent base with the puncture site. Then, gently press the fixing wing 23 to ensure that the transparent base is tightly adhered to the patient's skin and firmly fixed. When pressure needs to be applied to the puncture site, the medical staff rotates knob 3. Since knob 3 is threadedly connected to the threaded groove 9 at the top of the pressure cylinder 2, the rotational motion of knob 3 is converted into pressure along the threaded groove 9. Axial movement causes the top plate 11 and pressure plate 12 to move downwards. During this process, the compression spring 13 at the bottom of the threaded groove 9 is compressed, providing a certain buffer and support force for the pressure plate 12, allowing the pressure plate 12 to apply stable pressure to the skin around the puncture hole. The elastic deformation of the silicone material achieves pressure on the puncture hole, thus preventing leakage. The miniature pressure sensor embedded at the bottom of the pressure plate 12 detects the pressure applied by the pressure plate 12 around the puncture hole in real time and converts the pressure signal into an electrical signal. The electrical signal is transmitted to the digital display head 4 through the through hole 8 on the side wall of the pressure cylinder 2. The digital display head 4 then... Pressure data is displayed intuitively in digital form. Medical staff can adjust the pressure in real time based on the displayed values ​​to ensure the pressure is within the appropriate range. When knob 3 is rotated downwards to a certain distance, the telescopic cavity 14 aligns perfectly with the inner sliding cavity 18. The locking head 16, under the action of the telescopic spring 15, extends and engages with the inner sliding cavity 18 to prevent excessive pressure. Simultaneously, the locking head 16 pushes the guide plate 22, which in turn drives the button 20 to extend out of the outer sliding cavity 17 via the guide rod 21. When pressure adjustment is needed, pressing the button 20 pushes the guide plate 22 via the guide rod 21, causing the locking head 16 to retract into the telescopic cavity 14. Knob 3 can then rotate freely. Unlocking facilitates subsequent pressurization or depressurization operations. During device use, medical staff can directly observe the status of the puncture site through the circular transparent observation window 6 on the base layer 1. Every 2 hours, medical staff record the pressure value of the digital display 4 and, in conjunction with the patient's symptoms such as the degree of abdominal distension and vital signs, adjust the ascites drainage volume accordingly. When the exudate has soaked through the observation window 6 to 50% of the scale ring 7, the transparent adhesive base should be replaced in time to maintain good sealing and observation effect. The pressure data can be exported to the mobile terminal through the data output interface to generate a pressure change report, which is convenient for subsequent medical analysis and decision-making.
