Description

An automatic changing device for medical pads on a gynecological examination bed Technical Field

[0001] This utility model relates to the field of auxiliary medical equipment, specifically an automatic replacement device for a medical pad on a gynecological examination bed. Background Technology

[0002] Gynecological examination is an important means of diagnosing female reproductive organ diseases. To avoid cross-infection during gynecological examinations, medical drapes or paper used for gynecological examinations should be changed after each patient and be for single use only. Before the gynecological examination, medical staff or patients need to lay a disposable drape on the examination bed. The patient sits on the examination drape in the lithotomy position for the gynecological examination. After the gynecological examination is completed, the medical staff or patients discard the drape into the medical waste bin and replace it with a new drape. During the installation and replacement of medical drapes, numerous problems arise, including drapes being made of thin materials, varying in size, having different impermeability, and improper replacement methods. For example, thin drapes are prone to shifting or even slipping during installation and examinations, requiring repeated adjustments and leveling. Poor placement can also prevent effective isolation. Drapes with poor isolation properties can easily contaminate the gynecological examination bed with disinfectant, excrement, and bloodstains, requiring medical staff to disinfect the bed after each use, which is time-consuming, laborious, and inefficient. After replacing the drapes, they need to be rolled up and disposed of in the medical waste bin. Given the busy, assembly-line-style examination process, the high frequency of drape replacement not only increases the workload of medical staff but also poses a potential risk of cross-infection within the hospital.

[0003] Existing automatic gynecological medical pad changing devices generally adopt a front-to-back changing structure. During the changing process, the pad is transferred from front to back into the rear of the examination bed. The pad cannot completely cover the side of the examination bed. However, in actual use, patients usually get on and off the side of the examination bed, which increases the possibility of contact with the side of the examination bed and makes it easier to cause contamination of the side of the examination bed. In addition, such devices have high requirements for the space under the examination bed, and many examination beds cannot meet the installation requirements. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic medical pad replacement device for gynecological examination beds, which solves the technical problems of inconvenient installation and the inability to cover the sides of the examination bed in the existing medical pad replacement devices.

[0005] This utility model provides an automatic medical pad replacement device for a gynecological examination bed, including a support frame with a first side and a second side. The first and second sides of the support frame are respectively installed on both sides of the examination bed.

[0009] In an optional embodiment, the rotating shaft is located at the first end of the winding box, and the winding box is also provided with a second elastic support shaft that is opposite to the rotating shaft. The rotating shaft and the second elastic support shaft are respectively located at both ends of the winding box, and the two ends of the empty roll are respectively connected to the rotating shaft and the second elastic support shaft.

[0010] In an optional embodiment, the rotating shaft is provided with at least a first ridge, and the rotating shaft passes through the empty drum, the first ridge causing the empty drum to undergo elastic deformation.

[0011] In an optional embodiment, the winding box is provided with a top cover.

[0012] In an optional embodiment, a foot switch is also included, which controls the drive device.

[0013] In an optional embodiment, the examination bed further includes an embedded pad, which includes an impermeable layer, a sponge layer, and a reinforcing layer.

[0014] In an optional embodiment, the roll of medical pads can be unfolded into multiple medical pads, with a groove on one side of each pad, and the groove corresponding to the drain hole of the examination bed.

[0015] The automatic medical pad replacement device for gynecological examination beds provided by this utility model has the following beneficial effects:

[0016] 1. The first and second sides of the support frame are respectively installed on both sides of the examination bed.

[0033] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] This utility model provides an automatic changing device for a gynecological examination bed pad, as shown in Figures 1 to 5. Figure 1 is a side view of the overall structure of the automatic changing device for a gynecological examination bed pad provided by this utility model. Figure 2 is a top view of the overall structure of the automatic changing device for a gynecological examination bed pad provided by this utility model. Figure 4 is a structural schematic diagram of the unwinding assembly 200 of the automatic changing device for a gynecological examination bed pad provided by this utility model. Figure 5 is a structural schematic diagram of the winding assembly 300 of the automatic changing device for a gynecological examination bed pad provided by this utility model.

[0035] The automatic changing device for medical pads on a gynecological examination bed includes a support frame 100, which includes a first side 110 and a second side 120. The first side 110 and the second side 120 of the support frame 100 are respectively installed on both sides of the examination bed 400. The first side 110 of the support frame 100 is equipped with an unwinding assembly 200, which includes an unwinding box 210 with a feeding port 220. The unwinding box 210 contains a roll of medical pads 500. The second side 120 of the support frame 100 is equipped with a winding assembly 300, which includes a winding box 310, a rotating shaft 320, and a drive device 33. 0. The take-up box 310 is provided with a take-up opening 340. The rotating shaft 320 is located inside the take-up box 310. The medical pad 510, which is unrolled from the roll of medical pad 500, passes through the feed opening 220 and is fixed to the rotating shaft 320 through the take-up opening 340. The drive device 330 drives the rotating shaft 320 to rotate. A width adjustment mechanism is also provided between the first side 110 and the second side 120 of the support frame 100. The width adjustment mechanism can adjust the distance between the first side 110 and the second side 120 of the support frame 100. The feed opening 220 of the unwind box 210 and the take-up opening 340 of the take-up box 310 are both lower than the top surface 130 of the support frame 100.

[0036] When in use, the roll of medical pads 500 is placed in the unwinding box 210 beforehand. One of the medical pads 510 from the roll of medical pads 500 is pulled out from the unwinding box 210. One end of the medical pad 510 is connected to the roll of medical pads 500, and the other end is connected to the rotating shaft 320 of the take-up box 310.

[0037] Since the first side 110 and the second side 120 of the support frame 100 are respectively installed on both sides of the examination bed 400, and a width adjustment mechanism is provided between the first side 110 and the second side 120 of the support frame 100, the width adjustment mechanism can adjust the distance between the first side 110 and the second side 120 of the support frame 100. As a result, the automatic changing device for the medical pad of the gynecological examination bed provided by this utility model has a wider range of application scenarios, can be applied to gynecological examination beds 400 of different widths, and can completely cover the side of the examination bed 400, avoiding direct contact between the user and the examination bed 400 when getting on and off the examination bed 400 from the side.

[0038] Since the winding assembly 300 is equipped with a winding box 310, a rotating shaft 320 and a drive device 330, the drive device 330 drives the rotating shaft 320 to rotate, thereby pulling the used medical pad 510 into the winding box 310. The rotating shaft 320 can automatically recycle the used medical pad 510, which is convenient to operate and does not require operators to touch the used medical pad 510. It is clean and hygienic and reduces the need for cleaning procedures.

[0039] Since the feed opening 220 of the unwinding box 210 and the take-up opening 340 of the rewinding box 310 are both lower than the top surface 130 of the support frame 100, and the rewinding assembly 300 can pull the medical pad 510, the medical pad 510 can be tightly stretched on the top surface 130 of the support frame 100. The medical pad 510 has good flatness, and the patient feels more comfortable when using it.

[0040] Since the reel box 310 can store a certain amount of used medical pads 510, the used medical pads 510 can be cleaned in a centralized manner, which can reduce the need for cleaning used medical pads 510 and reduce the cleaning workload of medical staff.

[0041] In some embodiments, as shown in FIG1, the unwinding cassette 210 is provided with an elastic upper cover 230, which presses against the rolled medical pad 500 inside the unwinding cassette 210 under elastic action. The elastic upper cover 230 pressing against the rolled medical pad 500 prevents the rolled medical pad 500 from continuing to rotate due to inertia after the winding assembly 300 stops winding the rolled medical pad 500. The elastic upper cover 230 pressing against the rolled medical pad 500 prevents the rolled medical pad 500 from continuously rolling in the unwinding assembly 200 after the rotation shaft 320 of the winding assembly 300 stops rotating, thus ensuring that the unfolded medical pad 510 is in a taut state, ensuring the flatness of the rolled medical pad 500, and improving the comfort of the patient.

[0042] When the roll of medical pad 500 is placed into the unwinding box 210, the elastic top cover 230 can be opened upwards to form an opening at the top of the unwinding box 210 for placing the roll of medical pad 500.

[0043] The elastic cover 230 particles utilize structures such as coil springs and elastic bands to achieve elasticity, thereby pressing the elastic cover 230 onto the roll of medical pad 500. The elasticity of the elastic cover 230 also allows it to automatically close after the roll of medical pad 500 is placed into the unwinding box 210.

[0044] In some embodiments, as shown in Figures 2 and 4, the unwinding box 210 is provided with a fixed support shaft 240 and a first elastic support shaft 250 disposed opposite to each other. The fixed support shaft 240 and the first elastic support shaft 250 are respectively disposed at both ends of the unwinding box 210, and the fixed support shaft 240 and the first elastic support shaft 250 are respectively inserted into the rolled medical pad 500 from both ends.

[0045] The rolled medical pad 500, as a type of rolled structure, is generally a hollow roll with a hole in the middle. The fixed support shaft 240 is fixed to one end of the unwinding box 210. When placing the rolled medical pad 500 into the unwinding box 210, one end of the rolled medical pad 500 can be first slipped onto the fixed support shaft 240, while simultaneously pulling out the first elastic support shaft 250 to create a space for placing the rolled medical pad 500 into the unwinding box 210. Then, the first elastic support shaft 250 is released, and it returns to its original position under its own elasticity, allowing the other end of the rolled medical pad 500 to pass through. The first elastic support shaft 250 can achieve its elasticity through a spring structure.

[0046] In some embodiments, as shown in Figures 1, 2 and 5, the winding box 310 is further provided with an empty winding drum 520, which is connected to the rotating shaft 320, and the medical pad 510 is connected to the empty winding drum 520.

[0047] Using the empty roll 520 to collect used medical pads 510 avoids irregular winding of the medical pads 510 within the take-up box 310. Furthermore, the rotating shaft 320 only needs to drive the empty roll 520 to rotate, allowing for a shorter length and saving structural space. Additionally, the roll of medical pads 500 naturally generates an empty roll 520 after use, effectively utilizing this empty roll. After the roll of medical pads 500 is used up, the empty roll 520 is simultaneously filled with medical pads 510, allowing for simultaneous replacement of the roll of medical pads 500 in the unwinding box 210 and the empty roll 520 in the take-up box 310. This effectively prevents the accidental forgetting of the empty roll 520 or the accumulation of used medical pads 510 in the take-up box 310.

[0048] In some embodiments, as shown in Figures 2 and 5, a rotating shaft 320 is disposed at the first end of a winding box 310, and a second elastic support shaft 350 is disposed inside the winding box 310 opposite to the rotating shaft 320. The rotating shaft 320 and the second elastic support shaft 350 are respectively disposed at both ends of the winding box 310, and both ends of the empty drum 520 are respectively connected to the rotating shaft 320 and the second elastic support shaft 350.

[0049] When placing the empty drum 520 into the take-up cassette 310, one end of the empty drum 520 can be first fitted onto the rotating shaft 320. Simultaneously, the second elastic support shaft 350 is pulled out, creating a space to facilitate placing the empty drum 520 into the take-up cassette 310. Then, the second elastic support shaft 350 is released, and it returns to its original position under its own elasticity, then inserts into the other end of the empty drum 520. The second elastic support shaft 350 can achieve its elasticity through a spring-like structure.

[0050] In some embodiments, as shown in FIG5, the upper part of FIG5 shows a cross-sectional schematic diagram of the rotation shaft 320 and the empty drum 520. The rotation shaft 320 is provided with at least a first edge 321. The rotation shaft 320 passes through the empty drum 520, and the first edge 321 causes the empty drum 520 to undergo elastic deformation. Using a rotation shaft 320 with an edge facilitates fixing the empty drum 520 to the rotation shaft 320 by utilizing the deformation of the empty drum 520, ensuring that the empty drum 520 rotates with the rotation shaft 320. Specifically, the rotation shaft 320 can be set as a prism structure such as a triangular prism or a quadrangular prism to obtain at least a first edge 321.

[0051] In some embodiments, as shown in FIG1, the take-up cassette 310 is provided with an upper cover 360. The upper cover 360 can be opened upward to facilitate the placement of an empty roll 520 into the take-up cassette 310 and the removal of an empty roll 520 filled with medical pads 510 from the take-up cassette 310.

[0052] In some embodiments, the automatic changing device for the medical pad of the gynecological examination bed also includes a foot switch, which controls the drive device 330. Using a foot switch to control the drive device 330 facilitates operation by doctors, avoids additional contact by doctors' hands, and reduces the need for cleaning and disinfection.

[0053] In some embodiments, as shown in Figures 2 and 3, Figure 3 is an exploded structural diagram of the embedded pad 410 of the automatic changing device for medical pads on a gynecological examination bed provided by this utility model. The exploded structural diagram better illustrates the multi-layered structure of the embedded pad 410. The examination bed 400 also includes the embedded pad 410, which includes an anti-seepage layer 411, a sponge layer 412, and a reinforcing layer 413. The anti-seepage layer 411 can be made of PU (polyurethane) material, the sponge layer 412 can be made of high-density sponge, and the reinforcing layer 413 can be made of PVC (polyvinyl chloride) material. The anti-seepage layer 411, the sponge layer 412, and the reinforcing layer 413 are arranged sequentially from top to bottom. The anti-seepage layer 411 can effectively prevent liquid from seeping downwards, facilitating cleaning. The sponge layer 412 can provide a certain degree of elasticity and cushioning, making the patient's experience more comfortable. The reinforcing layer 413 provides overall structural strength and facilitates fixation to the examination bed 400, improving the installation firmness of the embedded pad 410.

[0054] In some embodiments, as shown in FIG2, the roll of medical pad 500 can be unfolded into multiple medical pads 510. One side of each medical pad 510 has a groove 414, which corresponds to a drain hole in the examination bed 400. The examination bed 400 typically has drain holes, and the groove 414 corresponds to these drain holes. The medical pad 510 also typically has an easy-tear line to form a groove 414 or notch to meet medical needs.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
