Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary equipment, and in particular to a pneumatic cold compress device. Background Art

[0002] Cold compress is a commonly used non-drug treatment method in the medical field, and is widely used in postoperative recovery, pain relief, and inflammation relief. It helps to relieve patients' discomfort through physical cooling and has a wide range of clinical application value. Traditional cold compress methods mainly include ice packs, gel pads, etc., which can quickly reduce local temperature and achieve analgesic and anti-inflammatory effects.

[0003] Although traditional cold compress methods can quickly reduce the temperature, they have many limitations: first, the contact area between ice packs and gel pads and the skin is limited, especially on complex curved parts of the body, it is difficult to achieve full coverage, resulting in unsatisfactory cold compress effects; second, ice packs melt easily and need to be replaced frequently, which increases the inconvenience and cost of operation and affects the user experience. Therefore, it is urgent to develop a new type of air pressure cold compress device that can effectively solve these problems. Summary of the invention

[0004] In view of the problems existing in the prior art, the present application provides an air pressure cold compress device.

[0005] The present application provides a pneumatic cold compress device, which adopts the following technical solution:

[0006] A pneumatic cold compress device comprises an air bag, an ice bag and an inflation device, wherein the air bag is provided with a fluff bonding surface, the ice bag is provided with a bristle bonding surface, and the ice bag is adhered to the air bag, a binding belt is provided on the air bag for binding and fixing the air bag to a body part of a patient, and the inflation device is connected to the air bag for delivering gas into the air bag.

[0007] By adopting the above technical solution, the air pressure cold compress device can effectively improve the cold compress effect.

At the same time, the airbag is tied and fixed to any part of the patient by the binding strap on the airbag, and the ice bag is close to the cold compress position to ensure that it will not shift or fall off during the cold compress process. Afterwards, gas is delivered into the airbag through the inflation device to expand the airbag and evenly apply pressure, so that the ice bag can better fit the patient's body part and improve the uniformity and effectiveness of the cold compress. In addition, by wrapping the ice bag with the airbag, an insulating cavity is formed inside the airbag, which can reduce the heat exchange between the ice bag and the outside air and slow down the melting rate of the ice bag, thereby effectively reducing the replacement frequency of the ice bag and improving the user experience.

[0008] Optionally, a plurality of balloons are provided on one side of the airbag close to the villi bonding surface, the balloons are integrally formed with the airbag, the villi bonding surface is provided with through holes for the balloons to pass through, the balloons are hollow and connected to the airbag, and the wall thickness of the balloons is greater than the wall thickness of the airbag.

[0009] By adopting the above technical solution, when the ice bag is attached to the air bag, the ice bag covers a part of the balloon ball. During the inflation process of the balloon ball, the ice bag is supported by the balloon ball, so that the air bag can better adapt to body parts of different shapes, increase the contact area between the ice bag and the skin, and improve the cold compress effect. At the same time, the wall thickness of the balloon ball is greater than the wall thickness of the air bag, which increases the structural strength of the balloon ball and enables the balloon ball to generate sufficient supporting force during the inflation process. Furthermore, through the setting of the balloon ball, a certain gap is generated between the air bag and the human skin, which increases the air permeability and avoids the local poor blood circulation caused by the long-term full coverage compression of the air bag at the cold compress position of the human body.

[0011] By adopting the above technical solution and setting the elastic connecting piece, when the airbag is not inflated, the balloon ball can be deformed into the airbag under the elastic force of the elastic connecting piece and shrink into the airbag, so that the ice bag can be attached to the fluff adhesive surface of the airbag. At the same time, when the airbag is inflated, the balloon ball protrudes out of the airbag again under the drive of the air pressure, so that it can fit the patient's body surface more closely, thereby improving the cold compress effect and comfort.

[0012] Optionally, the elastic connector includes an elastic rubber strip, one end of the elastic rubber strip is fixedly connected to the inner wall of the balloon ball, and the other end of the elastic rubber strip is fixedly connected to the inside of the airbag.

[0015] By adopting the above technical solution, the control circuit board is powered by a lithium battery, and then the air pump and the electromagnetic valve are controlled by the control circuit board to realize the function of stably delivering gas to the airbag. When the airbag is inflated, the connecting pipe is closed by the electromagnetic valve to avoid gas leakage in the airbag, thereby improving the convenience and reliability of the equipment.

[0016] Optionally, a pressure sensor is further provided in the host, and the pressure sensor is electrically connected to the control circuit board and is used to detect the air pressure in the connecting pipe.

[0017] By adopting the above technical solution, the pressure sensor can monitor the air pressure in the connecting tube in real time to ensure that the air pressure is within a safe range, avoiding poor cold compress effect or equipment damage caused by excessively high or low air pressure. At the same time, the control circuit board automatically adjusts the working state of the air pump and the solenoid valve according to the data fed back by the pressure sensor to keep the air pressure in the airbag stable, thereby improving the safety and effectiveness of the cold compress process.

[0018] Optionally, the connecting tube is detachably connected to the airbag, and a connecting piece for connecting to the airbag is provided on the connecting tube.

[0021] By adopting the above technical solution, by threading the connecting sleeve with the air inlet pipe on the airbag, quick installation and removal can be achieved, which is convenient for users to operate and maintain. In addition, this design makes the connection between the connecting pipe and the airbag more stable and reliable, avoids air leakage caused by loose connection, and improves the reliability of the equipment.

[0024] Optionally, the cold-proof protective cover is detachably connected to the airbag.

[0025] By adopting the above technical solution, the cold-proof protective cover is detachably connected to the airbag, which is convenient for the user to replace or clean the cold-proof protective cover according to actual needs, thereby improving the hygiene and comfort of the equipment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The air pressure cold compress device of the present application can effectively improve the cold compress effect. Specifically, the fluff adhesive surface on the airbag cooperates with the bristle adhesive surface on the ice bag to firmly adhere the frozen ice bag to the airbag. At the same time, the airbag is tied and fixed to any part of the patient by the binding strap on the airbag, and the ice bag is close to the cold compress position to ensure that it will not shift or fall off during the cold compress process. Afterwards, gas is delivered into the airbag through the inflation device to expand the airbag and evenly apply pressure, thereby prompting the ice bag to better fit the patient's body part and improving the uniformity and effectiveness of the cold compress. In addition, by wrapping the ice bag with the airbag and forming an insulating cavity inside the airbag, the heat exchange between the ice bag and the outside air can be reduced, and the melting rate of the ice bag can be slowed down, thereby effectively reducing the replacement frequency of the ice bag and improving the user experience.

[0028] 2. The present application sets a number of ice balls on one side of the airbag close to the villi bonding surface. When the ice bag adheres to the airbag, the ice bag covers a part of the ice ball. During the inflation of the ice ball, the ice bag is supported by the ice ball, so that the airbag can better adapt to body parts of different shapes, increase the contact area between the ice bag and the skin, and improve the cold compress effect. At the same time, the wall thickness of the ice ball is greater than the wall thickness of the airbag, which increases the structural strength of the ice ball and enables the ice ball to generate sufficient supporting force during the inflation process. Furthermore, through the setting of the ice ball, a certain gap is generated between the airbag and the human skin, which increases the air permeability and avoids the local poor blood circulation at the cold compress position of the human body due to the long-term full coverage compression of the airbag.

[0029] 3. The present application provides an elastic connector inside the balloon ball for driving the balloon ball to deform into the airbag. When the airbag is not inflated, the balloon ball can be deformed into the airbag under the elastic force of the elastic connector and shrink into the airbag, making it easier to stick the ice bag to the fluff bonding surface of the airbag. At the same time, when the airbag is inflated, the balloon ball bulges out of the airbag again under the drive of air pressure, making it fit the patient's body surface more closely, thereby improving the cold compress effect and comfort.

[0037] Reference Figure 1 The airbag 1 is made of soft PVC material with good flexibility and durability. The size of the airbag 1 can be adjusted according to different body parts. For example, a larger airbag 1 can be selected for the knee part, and a smaller airbag 1 can be selected for the wrist part. The fluff bonding surface 11 is composed of fine fibers and has strong adhesion ability, and can firmly adhere to the ice bag 2. In order to improve the adhesion effect, a thin layer of adhesive, such as acrylic adhesive, can be coated on the fluff bonding surface 11, so that a good adhesion effect can be maintained even in a humid environment.

The hair bonding surface 21 is composed of fine nylon fibers and can be tightly combined with the hair bonding surface 11 of the air bag 1. In order to increase the service life of the ice bag 2, a waterproof coating, such as a polyurethane coating, can be coated on the outer surface of the ice bag 2 to prevent moisture from penetrating into the interior of the ice bag 2 and affecting the cooling effect.

[0039] Reference Figure 1 The side of the airbag 1 away from the fluff bonding surface 11 is covered with a cold-proof protective cover 4, and the cold-proof protective cover 4 is connected to the airbag 1 by a zipper. Specifically, the cold-proof protective cover 4 is made of polyester fiber material, which has good thermal insulation performance and air permeability. The thickness of the cold-proof protective cover 4 is 2mm, which can effectively prevent the loss of cold caused by the excessively low external temperature of the airbag 1, and improve the sustainability and stability of the cold compress effect. The cold-proof protective cover 4 is connected to the airbag 1 by a zipper, and the user can replace or clean the cold-proof protective cover 4 at any time as needed, thereby improving the hygiene and comfort of the equipment.

The main unit 31 is made of ABS plastic and has the characteristics of being light and strong. The lithium battery 32 is electrically connected to the control circuit board 33 to power the control circuit board 33. The capacity of the lithium battery 32 is 3000mAh, which can ensure that the device can work continuously for several hours. The control circuit board 33 is electrically connected to the air pump 34 and the electromagnetic valve 35 respectively to control the opening and closing of the air pump 34 and the electromagnetic valve 35. The electromagnetic valve 35 is used to control the opening and closing of the connecting pipe 36. The control circuit board 33 is powered by the lithium battery 32, and the opening and closing of the air pump 34 and the electromagnetic valve 35 are controlled by the control circuit board 33, so as to realize the function of stably delivering gas into the airbag 1. When the airbag 1 is inflated, the connecting pipe 36 is closed by the electromagnetic valve 35 to prevent gas leakage in the airbag 1, thereby improving the convenience and reliability of the device.

[0042] Reference Figure 2A pressure sensor 37 is also provided in the host 31. The pressure sensor 37 is electrically connected to the control circuit board 33 and is used to detect the air pressure in the connecting tube 36. Specifically, the pressure sensor 37 is manufactured by MEMS (micro-electromechanical system) technology and has the characteristics of high precision and high sensitivity. The measurement range of the pressure sensor 37 is 0-15kPa, and the resolution is 0.1kPa, which can accurately detect the air pressure in the connecting tube 36. The pressure sensor 37 is connected to the control circuit board 33 through an I2C interface, with a high data transmission rate and a short response time. The control circuit board 33 automatically adjusts the working state of the air pump 34 and the solenoid valve 35 according to the data fed back by the pressure sensor 37, so that the air pressure in the airbag 1 remains stable, thereby improving the safety and effectiveness of the cold compress process.

[0043] Reference Figure 2 and Figure 3 In order to make the airbag 1 more convenient and quick to clean or replace, and improve the hygiene and durability of the equipment, the connecting pipe 36 is detachably connected to the airbag 1. Specifically, the connecting pipe 36 is provided with a connector for connecting the airbag 1, and the connector includes a connecting sleeve 361, which is rotatably sleeved on the end of the connecting pipe 36 away from the main unit 31. The airbag 1 is connected to the air inlet pipe 12, and the connecting sleeve 361 is provided with an internal thread, and the air inlet pipe 12 is provided with an external thread adapted to the connecting sleeve 361. By threading the connecting sleeve 361 with the air inlet pipe 12 on the airbag 1, quick installation and disassembly can be achieved, which is convenient for user operation and maintenance.

[0044] Reference Figure 3 , a plurality of balloons 13 are arranged on one side of the airbag 1 close to the villi bonding surface 11, the balloons 13 are integrally formed with the airbag 1, a through hole 111 for the balloons 13 to pass through is arranged on the villi bonding surface 11, the balloons 13 are hollow and connected with the airbag 1, and the wall thickness of the balloons 13 is greater than the wall thickness of the airbag 1. Specifically, the balloons 13 are made of TPU (thermoplastic polyurethane) material, which has excellent elasticity and wear resistance. The balloons 13 are integrally formed with the airbag 1, and are formed once by an injection molding process to ensure that the connection between the balloons 13 and the airbag 1 is firm and reliable. The diameter of the balloons 13 is about 10 mm, and the number can be adjusted according to the size of the airbag 1. Generally, 1-2 balloons 13 are arranged per square centimeter. The wall thickness of the balloons 13 is 1.5 mm, which is 0.5 mm greater than the wall thickness of the airbag 1, which increases the structural strength of the balloons 13, so that the balloons 13 can generate sufficient support force during the inflation process.

[0045] When the ice bag 2 is attached to the air bag 1, the ice bag 2 covers a part of the balloon 13. During the process of inflating the balloon 13, the balloon 13 supports the ice bag 2, so that the air bag 1 can better adapt to body parts of different shapes, increase the contact area between the ice bag 2 and the skin, and improve the cold compress effect. At the same time, the wall thickness of the balloon 13 is greater than the wall thickness of the air bag 1, which increases the structural strength of the balloon 13, so that the balloon 13 can generate sufficient supporting force during the inflation process. Furthermore, through the setting of the balloon 13, a certain gap is generated between the air bag 1 and the human skin, which increases the air permeability and avoids the local poor blood circulation caused by the long-term full coverage compression of the air bag 1 at the cold compress position of the human body.

[0046] Reference Figure 3 , an elastic connector is provided in the balloon ball 13, and the elastic connector is used to drive the balloon ball 13 to deform into the airbag 1. Specifically, the elastic connector includes an elastic rubber strip 14, one end of the elastic rubber strip 14 is fixedly connected to the inner wall of the balloon ball 13, and the other end is fixedly connected to the inside of the airbag 1. The elastic rubber strip 14 is made of silicone rubber material, has good elasticity and aging resistance, and the two ends of the elastic rubber strip 14 are respectively fixedly connected to the airbag 1 and the balloon ball 13 by ultrasonic welding or adhesive. When the airbag 1 is not inflated, the balloon ball 13 can be deformed into the airbag 1 under the elastic force of the elastic connector, and shrink into the airbag 1, so that the ice bag 2 can be attached to the fluff bonding surface 11 of the airbag 1. At the same time, when the airbag 1 is inflated, the balloon ball 13 protrudes out of the airbag 1 again under the drive of air pressure, so that it fits the patient's body surface more closely, improving the cold compress effect and comfort.

[0047] The implementation principle of a pneumatic cold compress device in an embodiment of the present application is as follows: the frozen ice bag 2 is firmly adhered to the air bag 1 by the cooperation between the fluff adhesive surface 11 on the air bag 1 and the bristle adhesive surface 21 on the ice bag 2. At the same time, the air bag 1 is tied and fixed to any part of the patient by the binding belt 41 on the air bag 1, so that the ice bag 2 is close to the cold compress position to ensure that it will not shift or fall off during the cold compress process. Afterwards, gas is transported into the air bag 1 through the inflation device 3 to expand the air bag 1 and evenly apply pressure, thereby causing the ice bag 2 to better fit the patient's body part and improve the uniformity and effectiveness of the cold compress. In addition, by wrapping the ice bag 2 with the air bag 1, an insulating cavity is formed inside the air bag 1, which can reduce the heat exchange between the ice bag 2 and the outside air, slow down the melting rate of the ice bag 2, and effectively reduce the replacement frequency of the ice bag 2, thereby improving the user experience.
