Description

Technical Field

[0001] The utility model relates to the technical field of medical assistance, in particular to a venous filling auxiliary belt suitable for elderly cardiovascular patients. Background Art

[0002] Veins are blood vessels that collect and return blood to the heart. They often run alongside corresponding arteries. They are more numerous than arteries, have a larger diameter, and hold more blood. Approximately 65-70% of the blood in the systemic circulation is contained in veins (excluding blood stored in the portal system, liver, and spleen). Veins in the pulmonary circulation contain approximately 50-55% of the blood. The walls of veins are thinner and more delicate than those of arteries, and their elasticity is also low. Therefore, in fixed and stained sections, the walls often collapse, and the lumen becomes flattened or irregular in shape. Venous congestion can be caused by a variety of factors, such as heart disease, hypertension, lung disease, and poor blood circulation. These factors lead to excessive cardiac load, insufficient cardiac output, and thus, congestion of the jugular vein. During venous congestion treatment, an auxiliary band is required to temporarily block venous blood flow, facilitating treatments such as venipuncture.

[0003] Common venous filling assistive belts suitable for elderly cardiovascular patients have a relatively simple structure. Medical staff usually manually tie the patient's limbs, and the tightening force cannot be adjusted or controlled. This lack of practicality reduces the patient's user experience. Therefore, we propose a venous filling assistive belt suitable for elderly cardiovascular patients. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings of the existing technology. The common venous filling auxiliary belt suitable for elderly cardiovascular patients has a relatively simple structure. In the process of tightening the patient's limbs, medical staff usually do it manually, and the tightening force cannot be adjusted and controlled. The practicality is insufficient, resulting in a reduced user experience for patients.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0028] like Figure 1-3 As shown, the utility model provides a technical solution: a venous filling auxiliary belt suitable for elderly cardiovascular patients, comprising a shell 1, a driving mechanism 2 is installed inside the shell 1, a groove 101 is provided at the top of the shell 1 near the back, rollers 102 are symmetrically installed inside the groove 101 near the front and back, a square groove 103 is provided at the top of the shell 1 near the front, a detachable component 104 is installed inside the square groove 103, and the outer periphery of the detachable component 104 is fixedly connected to the auxiliary belt body 105. Example

[0029] like Figure 1-3As shown, the bottom of the shell 1 is bonded with an anti-skid pad 106, which can increase the friction between the shell 1 and the desktop, prevent the device from sliding during use, and improve the stability of use. The roller 102 is rotatably connected to the groove 101, and the two rollers 102 are respectively arranged on the front and back of the auxiliary belt body 105. The rollers 102 can prevent friction between the auxiliary belt body 105 and the shell 1, thereby improving the service life of the auxiliary belt body 105 and also making the auxiliary belt body 105 move freely. The detachable component 104 includes a fixed rod 1041, and the left and right ends of the fixed rod 1041 are slidably connected to the insertion rod 1042. The interior of the fixed rod 1041 and the inner side of the insertion rod 1042 are fixedly connected with a return spring 1043. The insertion rod 1042 is plugged into the square groove 103. The return spring 1043 can continuously push the insertion rod 1042 to make it more firmly connected to the square groove 103, thereby improving the stability of use. Pushing the insertion rod 1042 inward can make it move out of the square groove. The inner part of the auxiliary belt body 105 is pulled out, thereby releasing the fixation between the auxiliary belt body 105 and the square groove 103, making it easier for the auxiliary belt body 105 to cover the patient's limb and improving the convenience of use. The driving mechanism 2 includes a driving gear 201, and the bottom of the driving gear 201 is meshed and connected with a gear bar 202. The left side of the driving gear 201 extends to the left side of the shell 1 and is fixedly connected to a turntable 203. By rotating the turntable 203, the driving gear 201 can be driven to rotate, so that the driving gear 201 drives the gear bar 202 to move back and forth inside the shell 1, thereby tightening the auxiliary belt body 105, and this process can be stopped and relaxed at any time to achieve the adjustment of the tightening force and improve practicality. The end of the auxiliary belt body 105 away from the detachable component 104 extends to the interior of the shell 1 and is fixedly connected to the gear bar 202. Through the fixed connection between the auxiliary belt body 105 and the gear bar 202, the gear bar 202 can drive one end of the auxiliary belt body 105 to move back and forth, thereby achieving the purpose of tightening the patient's limb and improving the convenience of use.

[0030] The working process of the present invention is as follows: when tightening the limbs of an elderly cardiovascular patient's venous filling auxiliary belt before treatment, the insertion rod 1042 is first pushed inward to disengage it from the square groove 103, allowing the patient to lift his limb and place it on the top of the shell 1, covering the surface of the patient's limb with the auxiliary belt body 105, and re-entering the fixing rod 1041 into the square groove 103. Under the action of the return spring 1043, the insertion rod 1042 is pushed outward to reinsert it into the square groove 103, completing the fixing work of the auxiliary belt body 105, and rotating the turntable 203 to drive the driving gear 201 to rotate, so that the driving gear 201 drives the auxiliary belt body 105 to gradually tighten through the gear bar 202, and tighten the patient's limb. When the tightening force is too great and the patient feels pain, the turntable 203 can be stopped or reversed to appropriately relax the auxiliary belt body 105, thereby achieving the purpose of freely adjusting the tightening force, greatly improving the practicality and effectively improving the patient's usage experience.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
