Description

Technical Field

[0001] This application relates to the field of nursing device technology, and more specifically, to an auxiliary device for treating peripheral vascular diseases. Background Technology

[0002] Peripheral vascular disease (PED) is a general term for diseases affecting the blood vessels of the limbs. Based on the blood vessels involved, it can be divided into arterial diseases and venous diseases. It is mainly caused by related underlying diseases or poor lifestyle habits. The main clinical manifestations include limb swelling, limb pain, and intermittent claudication. Currently, the gold standard for the diagnosis of most peripheral vascular diseases is angiography. Surgical treatment is the main approach, while mild cases can be treated with general treatment and medication. In the nursing care of peripheral vascular diseases, local care and treatment of the limbs are often required.

[0003] In response, Chinese patent application number CN202223492463.3 discloses an auxiliary device for treating peripheral vascular diseases. This solution mainly uses a crank to drive a screw to adjust the pitch of the massage tray and a motor to drive the height adjustment of the lifting mechanism, thereby improving the comfort of the patient's limbs when supported and helping the patient's recovery.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] 1. The crank is located on the device and requires assistance from someone else to crank it, making it inconvenient for self-adjustment;

[0006] 2. Motor-driven lifting requires an external power supply, making it less flexible in terms of application location. Summary of the Invention

Detailed Implementation

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art above, and the overall idea is as follows:

[0024] Please see Figures 1-4 An auxiliary device for treating peripheral vascular disease includes a massage pad 10, a hydraulically locked tilt mechanism 20, a hydraulically driven lifting mechanism 30, and a remote control mechanism 40. The massage pad 10 is mounted on the tilt mechanism 20, which is mounted on the lifting mechanism 30. The remote control mechanism 40 includes a hand pump 41 and a locking cylinder 42. The hand pump 41 is linked to the lifting mechanism 30, and the locking cylinder 42 is linked to the tilt mechanism 20. The hand pump 41 drives the lifting mechanism 30 to rise and fall, and the locking cylinder 42 locks the tilt mechanism 20, achieving remote adjustment. This allows for easy self-use by the patient, eliminates the need for an external power source, and provides greater flexibility in terms of location.

[0025] Please see Figures 1-4 The tilt mechanism 20 includes a base 21 and an arc-shaped seat 22. The arc-shaped seat 22 is slidably connected to the base 21 in an arc shape, and the arc-shaped seat 22 is fixedly connected to the massage pad 10. Here, when the limb is tilted onto the massage pad 10, the arc-shaped seat 22 can naturally match the support angle, eliminating the trouble of adjustment.

[0026] Please see Figures 1-4 The pitch mechanism 20 also includes a hydraulic rod 23, which is mounted on the base 21 and communicates with the locking cylinder 42. The arc-shaped seat 22 has a series of pin holes that match the extension and retraction ends of the hydraulic rod 23. Here, the hydraulic rod 23 functions as a pin. When the locking cylinder 42 is manually pushed, the oil in the locking cylinder 42 enters the hydraulic rod 23, pushing it to extend and engage with the pin holes on the arc-shaped seat 22, thus locking the pitch attitude.

[0027] Please see Figures 1-4 The locking cylinder 42 has a stop groove on its cylinder body, and a lever 43 is provided on the piston of the locking cylinder 42. The lever 43 moves within the stop groove. Here, the stop groove has two positions. When the lever 43 is pulled axially, it can push the piston to move, and then the lever 43 is circumferentially deflected and locked in the position, thereby locking the hydraulic rod 23.

[0028] Please see Figures 1-4 The lifting mechanism 30 includes a lower plate 31 and an upper plate 32. A scissor beam 33 is arranged between the lower plates 31 and the upper plate 32 is equipped with a hydraulic cylinder 34. The two ends of the hydraulic cylinder 34 are hinged to the upper plate 32 and the scissor beam 33, respectively. Here, the upper plate 32, the lower plate 31, and the scissor beam 33 constitute a lifting structure for the scissor beam 33. The extension and retraction of the hydraulic cylinder 34 can drive the scissor beam 33 to deflect, thereby pushing the upper plate 32 to rise and fall.

[0029] Please see Figures 1-4 An oil tank is installed inside the base 21, and the two ends of the hand pump 41 are connected to the hydraulic cylinder 34 and the oil tank, respectively. Here, the hand pump 41 is equipped with a one-way valve. When the hand pump 41 is repeatedly squeezed and released, the hydraulic oil in the oil tank is pumped into the hydraulic cylinder 34, thereby driving the scissor beam 33 to move and achieve the lifting effect. When the hand pump 41 is stopped, due to the action of the one-way valve, the oil is kept in the hydraulic cylinder 34, achieving height locking.

[0030] Please see Figures 1-4 A bypass valve 44 is connected in parallel to the hand pump 41. Here, when it is necessary to lower the pump, the bypass valve 44 is opened, and the oil in the hydraulic cylinder 34 returns to the oil tank through the bypass valve 44, thereby achieving the effect of lowering the height.

[0031] Please see Figures 1-4 The hand pump 41, bypass valve 44, and locking cylinder 42 are fixed together. Here, the hand pump 41, bypass valve 44, and locking cylinder 42 are fixed together and have an outer casing. They are connected to the lifting mechanism 30 and the pitching mechanism 20 through hydraulic hoses to form a remote control mechanism 40 for easy operation.

[0032] When this application is used: when the limb is raised onto the massage cushion 10, the arc-shaped seat 22 can naturally match the support angle, eliminating the trouble of adjustment. The hydraulic rod 23 is used as a pin. When the locking cylinder 42 is pushed by hand, the oil in the locking cylinder 42 enters the hydraulic rod 23, pushing the hydraulic rod 23 to extend and pin into the pin hole on the arc-shaped seat 22, thereby locking the pitch posture. When the hand pump 41 is repeatedly squeezed and released, the hydraulic oil in the oil tank can be pumped into the hydraulic cylinder 34, thereby driving the scissor beam 33 to move and achieve the lifting effect. When the hand pump 41 is stopped, due to the action of the one-way valve, the oil is kept in the hydraulic cylinder 34, achieving height locking. When it is necessary to lower, the bypass valve 44 is opened, and the oil in the hydraulic cylinder 34 returns to the oil tank through the bypass valve 44, achieving the height reduction effect.

[0033] In summary, by using the hand pump 41 to drive the lifting mechanism 30 to rise and fall, and by using the locking cylinder 42 to lock the pitch mechanism 20, the effect of remote adjustment is achieved, which is convenient for patients to use themselves. Moreover, no external power supply is required, and the usage location is more flexible.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
