Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and particularly relates to a disposable bed sheet automatic laying device for an external counterpulsation treatment bed. Background Art

[0002] An external counterpulsation treatment bed is an advanced medical device mainly used for treating ischemic diseases such as angina pectoris and myocardial infarction. Its working principle is to perform non-invasive sequential compression on the buttocks and lower limbs of the human body, synchronized with the cardiac cycle, to drive the blood flow back to the upper body, thereby improving the blood perfusion of important organs such as the heart and brain. This treatment method has the characteristics of non-invasive and non-interventional, and is known as "green treatment, natural treatment". To ensure hygiene and safety during the treatment process, the external counterpulsation treatment bed needs to be strictly cleaned and disinfected after each use. Among them, laying a disposable bed sheet is one of the important measures to ensure hygiene. The disposable bed sheet can effectively isolate the direct contact between the patient and the device, prevent cross-infection, and at the same time keep the treatment bed clean and comfortable. This helps to improve the treatment effect and patient satisfaction.

[0003] However, due to the design characteristics of the external counterpulsation treatment bed, it has 4 airbag sleeve packages for the lower limbs and buttocks, which increases the difficulty of laying the disposable bed sheet to a certain extent. When laying the bed sheet, medical staff need to ensure that the bed sheet covers the airbag sleeve package evenly. To avoid squeezing or displacement of the airbag sleeve package, it is necessary to avoid the airbag sleeve package and make it protrude outside the bed sheet to ensure the pressurization effect. This process is relatively cumbersome and requires medical staff to have high professional skills and patience. In addition, frequently replacing and laying the disposable bed sheet also increases the workload of medical staff and brings them an additional burden. Summary of the Invention

[0042] Embodiment

[0043] Due to the design features of the extracorporeal counterpulsation treatment bed, it has four airbag covers for the lower limbs and buttocks, which increases the difficulty of laying disposable bedspreads to a certain extent. When laying the bedspread, medical staff need to ensure that the bedspread covers the airbag covers evenly. In order to prevent the airbag covers from being squeezed or shifted, the airbag covers need to be avoided so that they extend out of the bedspreads to ensure the pressurization effect. This process is relatively cumbersome and requires medical staff to have high professional skills and patience. In addition, frequent replacement and laying of disposable bedspreads also increases the workload of medical staff and brings them an additional burden. For this reason, this embodiment proposes an automatic laying device for disposable bedspreads for extracorporeal counterpulsation treatment beds. The specific structure is as follows: Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 Schematic diagram of the overall structure at two different angles.

[0044] Specifically include:

[0045] The movable platform, the bed cover roller 7, two sets of bed cover toggle units, two bed side rolling units and two sensor units. The movable platform is respectively connected to the two symmetrically arranged bed side rolling units; the bed cover roller 7 is rolled with a plurality of disposable bed covers 20, and its two ends are respectively rotatably connected to the two bed side rolling units; three openings are opened from the middle to the tail end of the disposable bed cover 20; each set of bed cover processing units includes two movable components, which are slidably arranged on the top of the movable platform, as shown in the figure. Figure 3 As shown, Figure 3 It is a partial A structural diagram; one end of each moving component is fixedly provided with an elastic telescopic rod, which elastically contacts with the bed cover roller 7; the two elastic telescopic rods of each set of bed cover toggle units are fixed on the adjacent side of the two moving components; the two sensor units are respectively arranged on the two bed side rolling units; wherein, when laying, the two bed side rolling units roll with the two sides of the external counterpulsation treatment bed 1, and the two sensor units face the external counterpulsation treatment bed 1, and pull the moving platform, and when the sensor unit touches the air bag sleeve of the external counterpulsation treatment bed 1, the two moving components of each set of bed cover toggle units drive the elastic telescopic rods away and then gather together, and the two moving components of one set of bed cover toggle units move to the middle of the moving platform, drive away and then gather together, and toggle the three openings of the disposable bed cover 20 to avoid the air bag sleeve.

[0046] This embodiment adopts a toggling method to avoid the airbag sleeve and the airbag package. In addition, an electric knife can be set at the end of the elastic telescopic rod. When the two moving components of the elastic telescopic rod are driven to move away and then gather together, the disposable bed cover 20 is cut to avoid the airbag sleeve and the airbag package and avoid pressing the airbag sleeve and the airbag package.

[0047] Further, in order to fully stretch and lay flat the disposable bedspread 20, fixing members for fixing to both ends of the external counterpulsation therapy bed 1 are provided at the bottom of both ends of the disposable bedspread 20 of the present invention, and a magic tape structure can be specifically adopted for fixing.

[0048] In this embodiment, a roller structure is adopted as the bed-side rolling unit, as Figure 4 shown. Figure 4 It is a partial B structure diagram. The bed-side rolling unit includes an L-shaped frame plate 6 and side rollers 8. A notch is provided on one side plate of the L-shaped frame plate 6; both ends of the moving platform frame are fixedly connected to the tops of two L-shaped frame plates 6; the side rollers 8 are rotatably arranged in the notch through a rotating shaft; during laying, the two side rollers 8 are in rolling cooperation with both sides of the external counterpulsation therapy bed 1. In order to facilitate the movement of the overall moving platform frame, a traction rope frame 4 is provided at the top of each L-shaped frame plate 6, and a traction rope is fixedly arranged on the traction rope frame 4 for manual traction and movement.

[0049] Further, when the bed-side rolling unit drives the bedspread roller 7 to move, at this time, since the top of the external counterpulsation therapy bed 1 has an airbag sleeve and an airbag cover, it is extremely easy to collide with the bedspread roller 7, resulting in the airbag sleeve and the airbag cover being stuck between the bedspread roller 7 and the top of the external counterpulsation therapy bed 1. Therefore, the present invention proposes a structure of the bedspread roller 7 with adjustable up and down elasticity. Specifically, as Figure 4 shown, a notch is provided on one side surface of the L-shaped frame plate 6, and a buffer groove 9 is fixedly arranged outside one side surface thereof, and the groove body of the buffer groove 9 faces the notch; two elastic rotating members are respectively arranged at both ends of the bedspread roller 7 and connected to the buffer groove 9; the elastic rotating member includes a rotating shaft 18, a connecting plate 19 and a buffer spring 10. One end of the rotating shaft 18 is fixedly connected to one end of the bedspread roller 7 and passes through the notch, and the other end thereof is fixedly provided with a connecting plate 19; both ends of the buffer spring 10 are respectively connected to the connecting plate 19 and the bottom of the buffer groove 9.

[0050] The moving assembly given in this embodiment adopts a gear-rack transmission method, and multiple moving assemblies are independently driven. Specifically, as Figure 3 shown. The moving platform frame is a rack frame 3; a sliding groove body is provided in the middle of the rack frame 3; the moving assembly includes a moving platform 2, a gear 15 and a motor 14. The moving platform 2 includes two frame plates and a sliding block connecting the two frame plates; the sliding block is slidably arranged in the sliding groove body; the opposite surfaces of the two frame plates are respectively abutted against the top and bottom of the rack frame 3; the gear 15 is rotatably arranged between the two frame plates through a rotating shaft; the motor 14 is fixedly arranged on the top of the frame plate, and its output shaft is in transmission connection with the rotating shaft.

[0051] Furthermore, in order to better move the disposable bed cover 20 to achieve avoidance, the end of the elastic telescopic rod must abut against the bed cover roller 7. When the position is correct, it can smoothly enter the opening to achieve the moving avoidance. The elastic telescopic rod includes a telescopic sleeve 16, a telescopic spring and a toggle rod 5. One end of the telescopic sleeve 16 is fixedly connected to one side of the bottom frame; the telescopic spring is arranged in the telescopic sleeve 16, and one end thereof is fixedly connected to the telescopic sleeve 16; one end of the toggle rod 5 is sleeved in the telescopic sleeve 16 and fixedly connected to the other end of the telescopic spring. For accurate control, a feedback pressure sensor is provided at the other end of each toggle rod 5.

[0052] In addition, the sensing unit can be used as a pressure sensor or other distance measuring sensor to detect whether the airbag sleeve is in contact. The sensing unit includes a positioning guide rod 12 and a positioning pressure sensor 13. The positioning guide rod 12 is located on one side of the bed cover drum 7, and one end of the positioning guide rod 12 is connected to a side plate of the L-shaped frame plate 6 through a connecting spring 11; the positioning pressure sensor 13 is arranged at the other end of the positioning guide rod 12, and is facing the side away from the bed cover drum 7.

[0053] The device proposed in this embodiment innovatively introduces a semi-automatic bed cover laying mechanism, which greatly optimizes the bed cover laying process during the external counterpulsation treatment process. Through the ingeniously designed overall mobile stand, medical staff only need to pull it easily to start a series of precise and coordinated actions. In this process, the built-in sensor units of the device play a vital role. They can keenly sense the specific position of the airbag sleeve on the external counterpulsation treatment bed. Once the sensor unit comes into contact with the airbag sleeve, the bed cover toggle unit will be immediately activated. Each set of bed cover toggle units is equipped with two moving components, which can flexibly drive the elastic telescopic rod to move away and regroup through a precise drive system. Further, after completing the initial action, the two moving components of one set of bed cover toggle units will move specifically to the middle position of the mobile stand to avoid the middle airbag sleeve. This design is intended to ensure that when laying a disposable bed cover, the positions of all airbag sleeves can be accurately avoided, thereby effectively preventing the airbag package from being squeezed or displaced unnecessary during the laying process. Through this series of ingenious designs, the device not only reduces the complexity of traditional manual laying of disposable bedspreads, but also significantly improves the accuracy and efficiency of laying, truly realizing semi-automatic bed cover laying. This innovation not only reduces the workload of medical staff, but also further improves the treatment experience of patients.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
