Description

Technical Field

[0001] This utility model relates to the technical field of pressure sleeves, specifically a pressure sleeve for preventing deep vein thrombosis in the lower extremities after liver cancer surgery. Background Technology

[0002] Compression stockings, also known as elastic stockings or graduated compression stockings, are medical devices used to promote venous blood return in the lower limbs by applying external pressure, preventing and treating deep vein thrombosis, varicose veins, and other circulatory problems. Compression stockings are widely used post-operatively, for patients who are bedridden for extended periods, and for individuals who need improved lower limb blood circulation.

[0003] The shortcomings of existing technology:

[0004] The aforementioned pressure sleeves, due to their fixed elasticity, are not easily matched to the patient's body shape. This can easily result in the sleeve being too large, failing to apply sufficient gradient pressure to the lower limbs, thus preventing the patient from relieving the symptoms of deep vein thrombosis in the lower limbs. On the other hand, if the pressure sleeve is too small, it can easily apply excessive pressure to the lower limbs, causing obstruction of blood circulation in the lower limbs, which may lead to pain, numbness, or swelling, thereby endangering the patient's life.

[0033] Please see Figure 1-4 As shown, this utility model provides a pressure sleeve technical solution for preventing deep vein thrombosis in the lower extremities after liver cancer surgery:

[0034] A pressure sleeve for preventing deep vein thrombosis of the lower extremities after liver cancer surgery includes a support sleeve 1. An air pump 21 is installed on the outer side wall of the support sleeve 1, and a lifting mechanism 3 and an airbag 22 are installed on the inner side wall of the support sleeve 1. There are three lifting mechanisms 3, and the three lifting mechanisms 3 are evenly distributed along the circumference of the support sleeve 1. Each lifting mechanism 3 includes a slide rail 31, a slider 32 and a driving component 33. The driving component 33 includes a spring 331 and a driving rod 332.

[0035] The sidewall of the vertically arranged slide rail 31 is fixedly connected to the inner sidewall of the support sleeve 1. Multiple horizontally arranged sliders 32 are evenly distributed along the length of the slide rail 31. One side of each slider 32 extends into the slide rail 31 and is slidably connected to the sidewall of the slide rail 31. A connector 7 is installed on the other side of the slider 32, and the connector 7 is magnetically connected to the sidewall of the airbag 22. A ball bearing 8 is installed on the sidewall of the slider 32. One side of the ball bearing 8 is rotatably connected to the sidewall of the slider 32, and the other side of the ball bearing 8 contacts the sidewall of the slide rail 31. The connector 7 includes a magnetic conductor 72 and a magnetic component 71. The magnetic conductor 72 is located on the side of the slider 32 closest to the airbag 22 and is fixedly connected to the slider 32. The magnetic component 71 is located on the side of the airbag 22 closest to the slider 32 and is fixedly connected to the airbag 22. Specifically, the magnetic component 71 is a magnet, and the magnetic conductor 72 is made of magnetically conductive materials such as iron, nickel, or cobalt. The sidewall of the vertically positioned airbag 22 contacts the patient, and the airbag 22 is connected to the air pump 21. A one-way valve 62 and an air delivery tube 61 are installed on the airbag 22. The one-way valve 62 is located at the bottom of the airbag 22 and is connected to it. The vertically positioned air delivery tube 61 is located at the bottom of the one-way valve 62. One end of the air delivery tube 61 is connected to the one-way valve 62, and the other end is connected to the adjacent airbag 22. The air delivery tube 61 is a retractable flexible hose.

[0036] Multiple vertically arranged springs 331 are located between two adjacent sliders 32, and the two ends of each spring 331 are fixedly connected to the two adjacent sliders 32 respectively. A vertically arranged drive rod 332 is located at the bottom of the slider 32 and is fixedly connected to the bottom of the slider 32.

[0037] After the medical staff transfers the patient's lower limb into the support sleeve 1, they adjust the air pump 21 to inflate the air bag 22, so that the side wall of the air bag 22 is in contact with the patient's lower limb. At the same time, the volume of the air bag 22 is further adjusted through the air tube 61 and the one-way valve 62, so that the side wall of the air bag 22 fits the patient's lower limb. When treating patients of different body types, the size of the air bag 22 is adjusted through the air pump 21 and the one-way valve 62 to adapt to patients of different body types, thereby adjusting the air bag 22 to the set volume.

[0038] A drive source 4 is installed at the bottom of the drive rod 332. The drive source 4 includes a screw 42 and a screw sleeve 41. The vertically arranged screw 42 is located at the bottom of the drive rod 332 and is rotatably connected to the drive rod 332. The vertically arranged screw sleeve 41 is located at the bottom of the slide rail 31 and is rotatably connected to the slide rail 31. The top of the screw sleeve 41 is threadedly connected to the bottom of the screw 42.

[0039] A baffle 51 and an elastic block 52 are installed on the top of the slide rail 31. The side wall of the vertically arranged baffle 51 is fixedly connected to the side wall of the slide rail 31. The vertically arranged elastic block 52 is located at the bottom of the baffle 51 and is fixedly connected to the baffle 51. The bottom of the elastic block 52 is used to abut against the top of the slider 32.

[0040] Medical staff adjust the screw sleeve 41 to make it rotate. The screw 42 is threadedly connected to the screw sleeve 41, which drives the screw 42 to rise and fall, which in turn drives the drive rod 332 to rise and fall synchronously. This, in turn, drives the slider 32 to rise and fall synchronously. Through the elastic potential energy of the spring 331, multiple sliders 32 are driven to rise and fall synchronously, thereby adjusting the position of the airbag 22, increasing the contact area between the airbag 22 and the patient, thereby relieving the patient's local pressure, improving comfort, and further protecting the patient. At the same time, the baffle 51 and the elastic block 52 prevent the slider 32 from disengaging from the slide rail 31, making it convenient for medical staff to adjust the position of the airbag 22.

[0041] The working principle of this utility model is as follows:

[0042] In this embodiment, a pressure sleeve for preventing deep vein thrombosis in the lower extremities after liver cancer surgery is used. After the medical staff transfers the patient's lower limb into the support sleeve 1, they adjust the air pump 21 to inflate the airbag 22, thereby adjusting its volume so that the sidewall of the airbag 22 contacts the patient's lower limb. Simultaneously, the medical staff further adjusts the volume of the airbag 22 through the one-way valve 62 and the air tube 61 to accommodate patients of different body types. At the same time, the medical staff adjusts the screw sleeve 41, causing it to rotate, which in turn rotates the screw 42, causing the drive rod 332 to rise and fall. Through the elastic potential energy of the spring 331, the slider 32 rises and falls within the slide rail 31, thereby adjusting the position of the airbag 22, increasing the contact area between the airbag 22 and the patient, thus relieving local pressure on the patient, improving comfort, and further protecting the patient, ultimately enhancing patient safety.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
