Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly relates to an intermittent pneumatic compression device for preventing deep vein thrombosis. Background Technique

[0002] The intermittent pneumatic compression device is a widely used medical device, mainly composed of air bags, trachea and pressurizing equipment. It is usually used to treat embolism caused by venous thrombosis, and prevent diseases such as deep vein thrombosis and pulmonary embolism. It can simulate the state of the blood pump by squeezing muscles and blood vessels, so as to prevent or treat thrombosis;

[0003] However, when the existing intermittent pneumatic compression device is used, it is necessary to pre-wear leg sleeves for the patient and then wear the intermittent pneumatic compression device. There is more swinging of the legs, which is likely to cause discomfort to patients with inconvenient legs. In addition, the cloth cover wrapping the air bag is inconvenient to replace, which is not conducive to frequent washing and changing. Summary of the Invention

[0004] The main purpose of the utility model is to provide an intermittent pneumatic compression device for preventing deep vein thrombosis, which can effectively solve the technical problems in the background technique.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An intermittent pneumatic compression device for preventing deep vein thrombosis, including two air bags. One side of each of the two air bags is fixedly connected to a trachea. A protection mechanism is arranged outside the two air bags. The protection mechanism includes an outer cover. The inner side of the outer cover is movably connected to the two air bags, and a partition layer is fixedly connected to the inner side of the outer cover. One side of two magic tapes is fixedly connected to the rear part of the outer cover, and the other side of the two magic tapes is fixedly connected to a baffle cloth. One side of the outer cover is fixedly connected to a chain tooth, and a pull head is slidably connected to the outside of the chain tooth.

[0007] As a further scheme of the utility model, the front part of the outer cover is fixedly connected to the rear parts of two straps. One end of each of the two straps is fixedly connected to a hook surface sticker, and the other end of each of the two straps is fixedly connected to the rear part of a loop surface sticker.

[0008] As a further scheme of the utility model, the length of one of the two straps is greater than that of the other strap, and the length of the loop surface sticker is greater than that of the hook surface sticker.

[0009] As a further scheme of the utility model, the baffle cloth is trapezoidal in shape, and the size of the baffle cloth is slightly smaller than the rear part of the outer cover.

[0010] As a further scheme of the utility model, the two air bags are trapezoidal in shape with different sizes, and the outer cover is also trapezoidal in shape.

[0011] As a further solution of the present utility model, two circular holes are opened in the front part of the outer sleeve, and the diameters of the two circular holes are larger than the diameters of the two air tubes.

[0012] As a further solution of the present utility model, the thickness of the inner space of the outer sleeve is larger than the thicknesses of the two air bags, and the length of the chain teeth is greater than the length between the two farthest points of the two air bags.

[0013] The beneficial effects of the present utility model are as follows: By providing a protection mechanism, a blocking cloth can be used instead of the leg sleeve, which is pre-pasted on the outer sleeve through a magic tape. When the staff wears the intermittent pneumatic compression device for the patient, a barrier can be formed between the patient's leg and the intermittent pneumatic compression device, preventing the intermittent pneumatic compression device from rubbing the leg and causing discomfort, and avoiding direct contact between the patient and the intermittent pneumatic compression device, reducing the risk of cross-infection. After the intermittent pneumatic compression device is used up, the blocking cloth can be directly torn off, which is relatively convenient to operate and reduces the swing of the patient's leg, reducing the risk of causing injury and discomfort.

[0014] By providing chain teeth, the air bag can be conveniently taken out through the opening of the zipper. Since the intermittent pneumatic compression device needs to contact various patients, with the increase in the number of uses, the risk of being contaminated and causing cross-infection increases. Therefore, the outer sleeve wrapping the air bag needs to be frequently replaced and cleaned. By providing chain teeth, it is more convenient for the staff to disassemble and replace.

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Such as Figures 1-3As shown in the figure, an intermittent pneumatic compression device for preventing deep vein thrombosis includes two airbags 1. One side of each of the two airbags 1 is fixedly connected to a trachea 2. A protection mechanism 3 is provided outside the two airbags 1. The protection mechanism 3 includes an outer cover 4. The inner side of the outer cover 4 is movably connected to the two airbags 1, and a partition layer 5 is fixedly connected to the inner side of the outer cover 4. One side of two magic tapes 6 is fixedly connected to the rear part of the outer cover 4. The other side of the two magic tapes 6 is fixedly connected to a baffle cloth 7. One side of the outer cover 4 is fixedly connected to a chain tooth 11. A pull head 12 is slidably connected to the outside of the chain tooth 11.

[0021] In this embodiment, the front part of the outer cover 4 is fixedly connected to the rear parts of two straps 8. One end of each of the two straps 8 is fixedly connected to a hook surface sticker 9, and the other end of each of the two straps 8 is fixedly connected to the rear part of a loop surface sticker 10.

[0022] By providing the hook surface sticker 9, the strap 8 can be pulled and pasted on the loop surface sticker 10, so as to fix the intermittent pneumatic compression device on the patient's leg.

[0023] In this embodiment, the length of one of the two straps 8 is greater than that of the other strap 8, and the length of the loop surface sticker 10 is greater than that of the hook surface sticker 9.

[0024] Since the diameters of different parts of the human leg are different, the lengths of the two straps 8 are different according to the human body proportion.

[0025] In this embodiment, the outer shape of the baffle cloth 7 is trapezoidal, and the size of the baffle cloth 7 is slightly smaller than the rear part of the outer cover 4.

[0026] When the intermittent pneumatic compression device is worn on the patient's leg, since the baffle cloth 7 is at the innermost side, the cross-sectional diameter is the smallest. Therefore, it needs to be smaller than the rear part of the outer cover 4 in order to fit with the rear edge of the outer cover 4 after the intermittent pneumatic compression device is worn, and the magic tape 6 can paste the baffle cloth 7 on the rear part of the outer cover 4 to prevent it from falling off.

[0027] In this embodiment, the outer shapes of the two airbags 1 are trapezoids with different sizes, and the outer shape of the outer cover 4 is also trapezoidal.

[0028] The trapezoidal shapes of the two airbags 1 can adapt to different diameters of the leg and keep in contact with the leg.

[0029] In this embodiment, two round holes are opened in the front part of the outer cover 4, and the diameters of the two round holes are greater than the diameters of the two tracheas 2.

[0030] When taking out or placing the airbag 1, the trachea 2 can be passed through the round hole, so as to take out or put the airbag 1 and the trachea 2 into the inside of the outer cover 4.

[0031] In this embodiment, the thickness of the internal space of the outer cover 4 is greater than the thickness of the two airbags 1, and the length of the chain tooth 11 is greater than the length between the two farthest points of the two airbags 1.

[0032] The space inside the outer cover 4 is larger than the two air bags 1 , so as to accommodate the volume change of the two air bags 1 after being inflated.

[0033] It should be noted that the utility model is an intermittent pneumatic pressurization device for preventing deep vein thrombosis. When in use, the leg sleeve can be replaced by a blocking cloth 7, thereby omitting the process of wearing the leg sleeve separately, reducing the swinging of the patient's limbs, avoiding discomfort, and reducing the difficulty of wearing the intermittent pneumatic pressurization device;

[0034] The specific operation method is that before putting the intermittent pneumatic compression device on the patient, the back of the coat 4 is turned upward and arranged flat, and then the blocking cloth 7 is placed in the middle of the coat 4, and then the wider end of the blocking cloth 7 is opposite to the wider end of the coat 4, and the narrower end of the blocking cloth 7 is opposite to the narrower end of the coat 4, and then the two ends of the blocking cloth 7 are pressed on the Velcro 6;

[0035] After the blocking cloth 7 contacts the Velcro 6, the fine hook-shaped structure on the Velcro 6 will hook the fibers of the blocking cloth 7, thereby fixing the blocking cloth 7 so that it will not fall off. The blocking cloth 7 can play a role of blocking and isolating when the patient uses the intermittent pneumatic pressurization device, and saves the step of wearing the leg sleeve, making the operation simpler. After the intermittent pneumatic pressurization device is used, the blocking cloth 7 can be torn off;

[0036] During the use of the intermittent pneumatic pressurization device, it is easy to come into contact with various bacteria and pathogens on the patient. After the number of uses increases, it is easy to cause cross infection and needs to be cleaned frequently. By setting up the protection mechanism 3, it is easier for park personnel to disassemble and clean;

[0037] The specific operation method is to pull the pull head 12 to make the pull head 12 slide on the sprocket 11 and release the meshing of the sprocket 11, so as to open an outlet of the jacket 4. After the sprocket 11 is pulled open, the outlet is stretched open, and one end of the trachea 2 is pulled. After the trachea 2 is subjected to force, it will move toward the inside of the jacket 4 through the round hole of the jacket 4. After the other end of the trachea 2 is drawn into the jacket 4, the airbag 1 and the trachea 2 are grasped and taken out from the inside of the jacket 4. The other airbag 1 and the trachea 2 can be taken out by the same method.

[0038] After the airbag 1 and the trachea 2 are taken out, a new outer jacket 4 can be replaced. The specific operation method is to put the airbag 1 and the trachea 2 into the new outer jacket 4. Pay attention to the corresponding positions of the large and small airbags 1 in the outer jacket 4. The large airbag 1 is placed at the wider end of the outer jacket 4. After the airbag 1 and the trachea 2 are placed into the inner part of the outer jacket 4, the other end of the trachea 2 is extended to the outside of the outer jacket 4 through the round hole of the outer jacket 4.

[0039] Hold the other end of the trachea 2 from the outside of the outer sleeve 4, pull out the remaining part, and then pull the slider 12 in the opposite direction to make the slider 12 squeeze the chain teeth 11 to engage them, closing the inside of the outer sleeve 4 to complete the operation of replacing the outer sleeve 4 of the intermittent pneumatic compression device;

[0040] By setting the protection mechanism 3, the wearing steps of the intermittent pneumatic compression device can be simplified and the wearing difficulty can be reduced, the impact on the patient caused by wearing the intermittent pneumatic compression device can be reduced, and the outer sleeve 4 of the intermittent pneumatic compression device can be replaced quickly, keeping the intermittent pneumatic compression device hygienic and reducing the risk of cross-infection.
