Description

Technical Field

[0001] This invention relates to the field of compression device technology, specifically to an intelligent and comfortable compression device after inguinal artery puncture. Background Technology

[0002] Currently, clinical treatments involving femoral artery puncture in the groin include hepatic artery catheterization chemotherapy, digital subtraction angiography, and lower extremity artery interventional therapy. Bleeding, hematoma, and pseudoaneurysm formation at the puncture site are major complications after femoral artery puncture, often carrying a life-threatening risk. Therefore, effective compression hemostasis is necessary after such procedures. Post-operatively, the femoral artery routinely requires at least 6 hours of sandbag compression at the puncture site, 12 hours of limb immobilization, and 24 hours of bed rest. The increased patient discomfort and workload for medical staff are due to the pressure at the puncture site, limb immobilization, and the risk of bleeding at the puncture site. Compression hemostasis devices are required after femoral artery puncture surgery.

[0003] Existing compression hemostasis devices use straps to bind the device to the patient's limb. This not only causes congestion and discomfort in the patient's limb after prolonged use, but also makes it difficult to adjust the tightness. Secondary adjustments can damage the patient's wound, resulting in poor practicality. In addition, the safety and hygiene of existing compression hemostasis devices cannot be guaranteed after prolonged use, making it difficult to reuse them and increasing the cost of use. Furthermore, existing compression hemostasis devices have low intelligence, and prolonged use can cause discomfort to patients, making it difficult to promote their further use.

[0011] Preferably, the intelligent adjustment mechanism includes a sensing patch, which is located at the middle of the upper surface of the protective pad. The sensing patch is a temperature and humidity sensor.

An air supply pipe is fixedly connected to the left side of the fan, and the other end of the air supply pipe is inserted and fixed on the protective pad near the right side.

[0012] A method for using an intelligent and comfortable compression device after inguinal artery puncture includes the following steps:

[0013] S1: First, place the protective pad under the patient's waist and hips, and place the cloth bag above the patient's groin. You can place a layer of gauze above the patient's groin in advance to avoid the cloth bag coming into direct contact with the patient's skin, and make the airbag located directly above the puncture point.

[0014] S2: Then, if it is necessary to adjust the position of the airbag, the two T-shaped rods can be pulled upwards, which will also move the two pressure plates upwards, thereby causing several small toothed blocks to disengage from the fabric strip. Then, by pulling the fabric strip on one side, the connecting plate can be moved laterally in the inner cavity of the bag, thereby adjusting the lateral position of the airbag.

[0015] S3: After adjustment, by loosening the two T-shaped rods and driving the two pressure plates to reset under the setting of the two springs, several small toothed blocks are inserted into the surface of the cloth strip, thereby fixing the position of the airbag;

[0016] S4: Next, pull the first elastic band and the second elastic band on one side to make them fit together, and place the first elastic band and the second elastic band between two adjacent clamps;

[0017] S5: Then, by rotating several levers, the annular plate is rotated, the annular plate rotates, the threaded rod rotates, and the two threaded blocks move relative to each other, thereby causing the two clamping plates to clamp and fix the first elastic band and the second elastic band. Repeating the above operation can fix the first elastic band and the second elastic band on the other side.

[0018] S6: Next, by activating the electro-hydraulic actuator, the connecting block is moved and the restraint rod is moved, thereby squeezing the first elastic band and the second elastic band on the adjacent side, thereby adjusting the tightness of the restraint.

[0019] S7: In addition, through the cooperation between the mesh, rubber ball and rubber rope, the mesh can be moved upward after each use of the device and removed from the protective pad for replacement.

[0020] S8: During use, when the sensor patch, i.e. the temperature and humidity sensor, detects that the patient's lower back is hot or sweating, it can transmit the signal to the controller, and the controller will start the fan. The fan will adjust its output power according to the temperature and humidity, and cool air will be introduced into the protective pad through the air supply pipe. The breathability of the protective pad will be used to dissipate heat from the patient's lower back.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention involves placing a protective pad below the patient's waist and hips, and a cloth bag above the patient's groin. First, pull the first and second elastic bands on one side to make them fit together, and place the first and second elastic bands between two adjacent clamps. By rotating several levers, the annular plate is rotated, which in turn rotates the threaded rod and causes the two threaded blocks to move relative to each other. This causes the two clamps to clamp and fix the first and second elastic bands. Repeating the above operation can fix the first and second elastic bands on the other side. Then, by activating the hydraulic push rod, the connecting block is moved and the restraint rod is moved, which can compress the first and second elastic bands, thereby adjusting the tightness of the restraint. This avoids causing discomfort to the patient and secondary injury, while making the adjustment more convenient.

[0023] 2. This invention, through the cooperation between the mesh, rubber ball, and rubber rope, allows the mesh to be pulled upwards and removed from the protective pad after each use, thus improving the safety and hygiene of the device while reducing its operating cost.

[0024] 3. This invention utilizes the coordinated operation of the sensing patch, controller, fan, and air delivery pipe. When the sensing patch, i.e., the temperature and humidity sensor, detects that the patient's lower back is hot or sweating, it transmits the signal to the controller, which then activates the fan. The fan adjusts its output power according to the temperature and humidity, and cool air is delivered into the protective pad through the air delivery pipe. The breathability of the protective pad helps dissipate heat from the patient's lower back, preventing discomfort caused by prolonged stuffiness and thus improving patient comfort. By enhancing the intelligence of the compression device, it facilitates further widespread use. Attached Figure Description

Housings 24 are fixedly connected near the top of both sides of the bag 3, and third slots are provided at the bottom of both sides of the housings 24. The two fabric strips 13, on opposite sides, pass through the adjacent limiting slots and the inner cavities of the two third slots, and are fixedly connected to limiting plates 14.

[0037] The intelligent adjustment mechanism includes a sensor patch 29, which is located in the middle of the upper surface of the protective pad 1. The sensor patch 29 is a temperature and humidity sensor. A controller 30 is fixedly installed on the left side of the L-shaped plate 10 on the right side, near the bottom. A fan 31 is fixedly installed on the top of the L-shaped plate 10 on the right side. An air supply pipe 32 is fixedly connected to the left side of the fan 31, and the other end of the air supply pipe 32 is inserted and fixed on the protective pad 1 near the right side. By improving the intelligence of the device, the comfort of the patient during use can be improved, thus facilitating the further promotion and use of the device.

[0038] A method for using an intelligent and comfortable compression device after inguinal artery puncture includes the following steps:

[0039] S1: First, by placing the protective pad 1 under the patient's waist and hips and the cloth bag 3 above the patient's groin, a layer of gauze can be placed above the patient's groin in advance to prevent the cloth bag 3 from directly contacting the patient's skin, and to make the airbag 5 located directly above the puncture point.

[0040] S2: Then, if it is necessary to adjust the position of the airbag 5, the two T-shaped rods 27 can be pulled upward and the two pressure plates 25 can be moved upward, so that several small toothed blocks 26 are disengaged from the cloth strip 13. Then, by pulling the cloth strip 13 on one side, the connecting plate 4 can be moved laterally in the inner cavity of the bag 3, so that the lateral position of the airbag 5 can be adjusted.

[0041] S3: After adjustment, by loosening the two T-shaped rods 27 and driving the two pressure plates 25 to reset under the setting of the two springs 28, a number of small toothed blocks 26 are inserted into the surface of the cloth strip 13, thereby fixing the position of the airbag 5.

[0042] S4: Next, pull the first elastic band 9 and the second elastic band 8 on one side to make them fit together, and place the first elastic band 9 and the second elastic band 8 between two adjacent clamps 15;

[0043] S5: Then, by rotating several levers 12, the annular plate 11 is rotated. The rotation of the annular plate 11 causes the threaded rod 17 to rotate, and causes the two threaded blocks 16 to move relative to each other, thereby causing the two clamping plates 15 to clamp and fix the first elastic band 9 and the second elastic band 8. Repeating the above operation can fix the first elastic band 9 and the second elastic band 8 on the other side.

[0044] S6: Next, by activating the electro-hydraulic actuator 19, the connecting block 20 is moved and the restraint rod 21 is moved, thereby squeezing the first elastic band 9 and the second elastic band 8 on the adjacent side, thereby adjusting the tightness of the restraint.

[0045] S7: In addition, through the cooperation between the mesh 2, the rubber ball 23 and the rubber rope 22, the mesh 2 can be pulled upwards and removed from the protective pad 1 after each use of the device and replaced with a new one.

[0046] S8: During use, when the sensing patch 29, i.e. the temperature and humidity sensor, detects that the patient's lower back is hot or sweating, it can transmit the signal to the controller 30, and the controller 30 will start the fan 31 to work. The fan 31 will adjust its output power according to the temperature and humidity, and input cold air into the protective pad 1 through the air supply pipe 32. The breathability of the protective pad 1 can be used to dissipate heat from the patient's lower back.

[0047] Working Principle: In use, the protective pad 1 is placed below the patient's waist and hips, and the cloth bag 3 is placed above the patient's groin. A layer of gauze can be placed above the patient's groin beforehand to prevent the cloth bag 3 from contacting the patient's skin, ensuring that the airbag 5 is directly above the puncture point. If the position of the airbag 5 needs to be adjusted, the two T-shaped rods 27 can be pulled upwards, causing the two pressure plates 25 to move upwards, thereby disengaging several small toothed blocks 26 from the cloth strip 13. Then, by pulling one side of the cloth strip 13, the connecting plate 4 moves laterally within the cavity of the cloth bag 3, thus adjusting the lateral position of the airbag 5. After adjustment, the two T-shaped rods 27 can be released. A T-shaped rod 27, driven by two springs 28, resets two pressure plates 25, allowing several small toothed blocks 26 to be inserted into the surface of the cloth strips 13, thus preventing the cloth strips 13 on both sides from moving and fixing the position of the airbag 5. Adjusting the position of the airbag 5 allows for adjustment according to different patient sizes, improving the applicability of the device. Next, pull the first elastic band 9 and the second elastic band 8 on one side to make them fit together, and place the first elastic band 9 and the second elastic band 8 between two adjacent clamping plates 15. By rotating several actuating rods 12, the annular plate 11 rotates, causing the threaded rod 17 to rotate, and driving the two threaded blocks 16. The relative movement causes the two clamping plates 15 to clamp and fix the first elastic band 9 and the second elastic band 8. Repeating the above operation can fix the first elastic band 9 and the second elastic band 8 on the other side. Then, by activating the electro-hydraulic actuator 19, the connecting block 20 is moved, which in turn moves the restraint rod 21, thereby squeezing the first elastic band 9 and the second elastic band 8 on the adjacent side. This allows for adjustment of the tightness of the restraint, avoiding patient discomfort and secondary injury, while also making adjustment more convenient. In addition, through the cooperation between the mesh 2, the rubber ball 23, and the rubber rope 22, the mesh 2 can be pulled upwards after each use of the device, and the mesh 2 can be removed from the protective pad 1. After being disassembled, it can be replaced with a new one, thereby improving the safety and hygiene of the device while reducing the cost of use. When the sensing patch 29, i.e. the temperature and humidity sensor, detects that the patient's lower back is hot or sweating, it can transmit the signal to the controller 30, and the controller 30 will start the fan 31 to work. The fan 31 can reasonably adjust the output power according to the temperature and humidity, and input cold air into the protective pad 1 through the air supply pipe 32. The breathability of the protective pad 1 can dissipate heat from the patient's lower back, avoiding the discomfort caused by prolonged stuffiness and heat on the lower back, thereby improving the patient's comfort. By improving the intelligence of the compression device, it is easier to promote its use.
