Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a foot-operated paper-retrieving device for use in operating rooms. Background Technology

[0002] The operating room is an environment with extremely high requirements for hygiene and sterility. After handwashing during surgery, hands and arms are dried with boiled, sterilized towels or disposable sterile paper towels. Medical staff also need to use sterile paper towels during surgery. Currently, many hospitals use wall-mounted paper towel dispensers. During the handwashing process, medical staff use dedicated sterile paper towels to dry their hands and then apply hand sanitizer for disinfection. During this process, contact with other sources of contamination should be avoided as much as possible to prevent incomplete disinfection. For current medical sterile paper towels and dispensers, to meet the hygiene requirements of the operating room, a contamination-proof cover is usually installed to protect the sterile paper towels inside the dispenser. During use, medical staff need to touch the dispenser to trigger the opening mechanism of the contamination-proof cover, open it, take the paper towels from the bottom of the dispenser, and then close the cover. This process involves direct contact between the medical staff's hands and the dispenser, directly increasing the risk of hand contamination. Current wall-mounted tissue boxes require medical staff to operate them by hand, which directly increases the risk of hand contamination for medical staff.

[0003] To address the aforementioned problems, the inventors designed a foot-operated paper dispensing device for operating rooms, which can effectively reduce hand contamination during the dispensing process from wall-mounted tissue boxes. Utility Model Content

[0004] The purpose of this invention is to provide a foot-operated paper-retrieving device for use in operating rooms, addressing the shortcomings of existing technologies.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A foot-operated paper dispensing device for operating rooms includes a contamination-proof cover, a housing, and a paper outlet. The paper outlet is located on the housing, and the contamination-proof cover is hinged to the housing, serving to cover the paper outlet. The device also includes an internal transmission support, a pull rope, and a foot pedal. The internal transmission support cooperates with the contamination-proof cover and controls the degree of rotation of the contamination-proof cover relative to the housing, allowing the cover to either cover or release the paper outlet. One end of the pull rope is connected to the internal transmission support, and the other end is connected to the foot pedal. Stepping on the foot pedal moves the pull rope, which in turn pulls the internal transmission support, causing the contamination-proof cover to rotate and release its obstruction of the paper outlet. After the external force on the foot pedal is removed, the contamination-proof cover returns to its original position covering the paper outlet.

[0007] As the preferred technical solution of this application, the anti-pollution cover has a natural state. When the anti-pollution cover is in its natural state, it covers the paper outlet under the influence of its own gravity.

[0008] As the preferred technical solution of this application, the anti-pollution cover is provided with a detachable hinge groove, and the internal transmission bracket is disposed in the hinge groove.

[0009] As the preferred technical solution of this application, the anti-pollution cover hinge groove is provided with an inclined portion, which is used to limit the maximum opening angle of the anti-pollution cover.

[0010] As the preferred technical solution of this application, the anti-pollution cover hinge groove is made of a hard material.

[0011] As the preferred technical solution of this application, the internal transmission support includes multiple sets of transmission supports.

[0012] As the preferred technical solution of this application, the internal transmission bracket is made of a rigid material.

[0013] As a preferred technical solution of this application, it also includes a spring and a foot pedal fixing plate. One end of the foot pedal fixing plate is hinged to the inclined section of the foot pedal, and one end of the spring is disposed on the upper surface of the foot pedal fixing plate, and the other end is disposed on the lower surface of the parallel section of the foot pedal.

[0014] As the preferred technical solution of this application, the pull rope includes a pull rope section, a pull rope section, and a mating component. The mating component includes a cylinder, a first piston, and a second piston. Both the first and second pistons are placed inside the cylinder. One end of the pull rope section is connected to the first piston, and the other end is connected to an internal transmission bracket. One end of the pull rope section is connected to the second piston, and the other end is connected to a foot pedal. A first chamber is formed between the first and second pistons, and the first chamber can be in a sealed state. Both the first and second pistons can move along the length of the cylinder. The cylinder is fixed to the outer shell. A first spring is connected between the first piston and the cylinder, and a second spring is connected between the second piston and the cylinder. Both the first and second springs are elastic, and both the first and second springs are used to reset the corresponding first or second piston.

[0015] As the preferred technical solution of this application, the cylinder is provided with an opening, and a switch is provided at the opening. The switch is used to control the size of the opening so that the opening is opened or blocked, and the opening is always in communication with the first chamber.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this application, the foot pedal paper dispensing device for operating rooms is designed for a sterile environment. Foot operation avoids hand contact, reducing the risk of contamination, whereas ordinary tissue boxes typically lack this sterile operation feature. The foot pedal paper dispensing device allows medical staff to retrieve paper without touching the tissue box, thus maintaining hand sterility and improving surgical efficiency. Due to the sterile characteristics of the foot pedal paper dispensing device, it helps reduce the risk of cross-infection.

[0018] The anti-contamination cover of this device has an inclined part in its hinge groove. The inclined part and the internal transmission support form an angle. When the anti-contamination cover is in its natural state, the angle between the internal transmission support and the inclined part is the largest. When the anti-contamination cover is opened to the maximum angle, the angle between the internal transmission support and the inclined part is the smallest. When the angle is the smallest, the inclined part contacts the internal transmission support. At this time, the inclined part will restrict the further movement of the internal transmission support. Even if medical staff continue to apply force to the foot pedal, the anti-contamination cover cannot be flipped further and can only maintain the maximum opening angle.

[0019] The internal support system converts the force output by medical staff into the power for the anti-contamination cover to flip. This internal transmission support forms a conversion system. According to the principles of materials science, materials with higher hardness exhibit less deformation under the same force because they have a higher elastic modulus, meaning they resist deformation more effectively under stress. Therefore, using a harder material reduces the deformation of the internal support under force, thereby reducing energy loss and improving the overall system efficiency. Attached Figure Description

[0030] Example 1: This example provides a foot-operated paper dispensing device for use in an operating room. See [link to example]. Figures 1-3 As shown, the device includes a contamination-proof cover 100, a housing 700, and a paper outlet 200. The paper outlet 200 is disposed on the housing 700, and the contamination-proof cover 100 is hinged to the housing. The contamination-proof cover 100 is used to cover the paper outlet 200. The device also includes an internal transmission support 1100, a pull rope 300, and a foot pedal 400. The internal transmission support 1100 cooperates with the contamination-proof cover 100 and is used to control the degree of rotation of the contamination-proof cover 100 relative to the housing 700, so that the contamination-proof cover 100 can rotate relative to the paper outlet 200. The pull cord 300 can block or release the obstruction of the paper outlet 200. One end of the pull cord 300 is connected to the internal transmission bracket 1100, and the other end is connected to the foot pedal 400. By stepping on the foot pedal 400, the foot pedal 400 drives the pull cord 300 to move. The pull cord 300 pulls the internal transmission bracket 1100, which causes the internal transmission bracket 1100 to rotate and release the obstruction of the paper outlet 200. After the external force is removed from the foot pedal 400, the obstruction of the paper outlet 200 is restored.

[0031] Operating room foot-operated tissue dispensers are designed for sterile environments. By using a foot pedal, they avoid hand contact, reducing the risk of contamination—a feature typically lacking in ordinary tissue dispensers. These foot-operated dispensers allow healthcare workers to retrieve tissues without touching the dispenser, maintaining hand sterility and improving surgical efficiency. Due to their sterile characteristics, they help reduce the risk of cross-infection.

[0032] As a preferred embodiment, based on the above method, the anti-pollution cover 100 further has a natural state. When the anti-pollution cover 100 is in its natural state, it covers the paper outlet 200 under the influence of its own gravity.

[0033] The natural state is defined as follows: when the foot pedal paper dispensing device in the operating room is not subjected to external force, it is in a preset equilibrium state. This state is determined by the design of the device to ensure hygiene and convenience for the next use when not in use. In the absence of external force, the anti-contamination cover 100 naturally droops due to gravity, covering and shielding the paper outlet 200 to prevent dust, bacteria, or other contaminants from contacting the paper. When medical staff use the foot pedal paper dispensing device, the force applied through the foot pedal 400 causes the anti-contamination cover 100 to open, allowing the paper to be removed. Once the paper dispensing action is completed, the medical staff stops applying force to the foot pedal 400. After the force disappears, the anti-contamination cover 100 automatically returns to its original position, i.e., the natural state, under the influence of gravity. This design ensures that the anti-contamination cover 100 is always closed when not in use, maintaining the hygiene and sterility of the device. This design allows the anti-contamination cover 100 to close automatically when not in use, reducing the need for manual operation, improving the work efficiency of medical staff, and reducing the risk of cross-infection.

[0034] As a preferred embodiment, based on the above method, the anti-pollution cover 100 is further provided with a detachable anti-pollution cover hinge groove 101, and the internal transmission bracket is disposed in the anti-pollution cover hinge groove 101.

[0035] The anti-contamination cover hinge slot 102 plays a crucial mechanical connection role in the device, effectively transmitting driving force and ensuring the smooth opening and closing of the anti-contamination cover 100. Since the anti-contamination cover hinge slot 101 is a connector between two moving parts, it is prone to wear during long-term use. The detachable design of the anti-contamination cover hinge slot 101 allows for replacement after wear, reducing maintenance costs and downtime caused by wear and extending the overall service life of the device.

[0036] As a preferred embodiment, based on the above method, the anti-pollution cover hinge groove 102 is further provided with an inclined portion, the inclined portion 102 being used to limit the maximum opening angle of the anti-pollution cover 100.

[0037] The inclined portion 102 and the internal transmission support form an angle. When the anti-contamination cover is in its natural state, the angle between the internal transmission support 1100 and the inclined portion 102 is the largest. When the anti-contamination cover 100 is at its largest opening angle, the angle between the internal transmission support 1100 and the inclined portion 102 is the smallest. When the angle is the smallest, the inclined portion 102 is in contact with the internal transmission support 1100. At this time, the inclined portion 102 will restrict the further movement of the internal transmission support 1100. Even if medical staff continue to apply force to the foot pedal 400, the anti-contamination cover 100 cannot continue to flip and can only maintain the maximum opening angle.

[0038] As a preferred embodiment, based on the above method, the anti-pollution cover hinge groove 101 is further made of a rigid material.

[0039] Medical staff apply a downward force through the foot pedal 400, which is transmitted through the mechanical structure of the foot pedal 400, causing the anti-contamination cover 100 to open. This process involves the principle of mechanical levers, where the foot pedal 400 is the input end of the force, and the opening of the anti-contamination cover 100 is the output effect of the force. When the anti-contamination cover 100 reaches its maximum opening angle, its inclined portion 102 contacts the internal transmission support 1100. This contact is part of the design to limit the opening angle of the anti-contamination cover and ensure that it does not over-expand. At the point of contact, an interaction force is generated between the inclined portion 102 and the internal transmission support 1100. The magnitude of this force is proportional to the force applied to the foot pedal 400; that is, the greater the applied force, the greater the contact force. Due to the suddenness and rapid transmission of the force, the contact between the inclined portion 102 and the internal transmission support 1100 may be accompanied by an instantaneous impact force. This impact force is determined by the rapid transmission of the force and the dynamic characteristics of the mechanical structure. To improve the service life and reliability of the device, the anti-pollution cover hinge groove 101 is made of a rigid material. Rigid materials typically have higher wear resistance and impact resistance, which can effectively reduce the risk of damage caused by repeated impacts, thereby extending the service life of the product.

[0040] Example 2:

[0041] Based on the technical solution of Embodiment 1, further details can be found in [reference needed]. Figure 2 and Figure 4 As shown, the internal transmission support 1100 includes multiple sets of transmission supports.

[0042] The system comprises two sets of transmission supports, each set including an equal number of first transmission supports 1101 and second transmission supports 1102. These supports are identical in structure and number and are all located on the same side of the anti-pollution cover 100. One end of each first transmission support 1101 is positioned within the anti-pollution cover hinge groove 101 to ensure a secure connection between the first transmission support 1101 and the anti-pollution cover 100, while allowing for a certain degree of rotation. The other end of the first transmission support 1101 is connected to one end of the second transmission support 1102, while the other end of the second transmission support 1102 is positioned within the housing hinge groove 701. This design allows the second transmission support 1102 to connect to the housing 700 while maintaining linkage with the first transmission support 1101. Each pair of transmission supports is symmetrically arranged on both sides of the anti-pollution cover 100 to ensure structural balance and symmetry, which is crucial for the stability and dynamic balance of the transmission system. Between the two symmetrically arranged sets of transmission supports, a plurality of third transmission supports 1103 are also provided. These third transmission supports 1103 are positioned between two symmetrical second transmission supports 1102, further enhancing the stability and strength of the structure. The entire transmission support system is designed to provide stable support and precise transmission, while allowing necessary rotation and flexibility. This design helps reduce vibration, improve transmission efficiency, and ensure long-term stable operation.

[0043] As a preferred embodiment, based on the above method, the internal transmission support 1100 is further made of a rigid material.

[0044] The internal support 1100 converts the force output by medical personnel into the power for the anti-contamination cover 100 to rotate. The internal transmission support 1100 forms a conversion system. According to the principles of materials science, materials with higher hardness exhibit less deformation under the same force because they have a higher elastic modulus, meaning they resist deformation more effectively under stress. Therefore, using a harder material reduces the deformation of the internal support under force, thereby reducing energy loss and improving the efficiency of the entire system.

[0045] As a preferred embodiment, based on the above method, the device further includes a spring 500 and a foot pedal fixing base plate 600. One end of the foot pedal fixing base plate is hinged to the inclined section of the foot pedal 400. One end of the spring 500 is disposed on the upper surface of the foot pedal fixing base plate 500, and the other end is disposed on the lower surface of the parallel section of the foot pedal 400.

[0046] The foot pedal fixing base plate 600 securely fixes the foot pedal 400 in a specific position via a mechanical connection to prevent displacement or shaking during use. When the user applies force to the foot pedal 400, the spring 500 compresses; when the force is released, the spring 500 returns the foot pedal to its original position.

[0047] In a preferred embodiment, based on the above method, the pull rope 300 further includes a pull rope section 301, a pull rope section 302, and a mating component 303. The mating component 303 includes a cylinder 304, a first piston 305, and a second piston 306. Both the first piston 305 and the second piston 306 are placed inside the cylinder 304. One end of the pull rope section 301 is connected to the first piston 305, and the other end is connected to an internal transmission bracket. One end of the pull rope section 302 is connected to the second piston 306, and the other end is connected to a foot pedal. The first piston 305 and the second piston 306... A first chamber is formed between the plugs 306, and the first chamber can be in a sealed state; the first piston 305 or the second piston 306 can move along the length direction of the cylinder 304; the cylinder 304 is fixed to the outer shell; a first spring 307 is connected between the first piston 305 and the cylinder 304, and a second spring 308 is connected between the second piston 306 and the cylinder 304; both the first spring 307 and the second spring 308 are elastic, and both the first spring 307 and the second spring 308 are used to reset the corresponding first piston 305 or second piston 306.

[0048] As a preferred embodiment, based on the above method, the cylinder 304 is further provided with an opening 309, and a switch 310 is provided at the opening 309. The switch 310 is used to control the size of the opening 309 so that the opening 309 is opened or blocked. The opening 309 is always in communication with the first chamber. The specific structure of the switch 310 is almost existing, so it will not be described in detail here.

[0049] Furthermore, by setting a mating component, one end of the pull rope is connected to the first piston, and the other end is connected to the second piston. When the first chamber is sealed, pressing the foot pedal pulls the second end of the pull rope, which in turn moves the second piston closer to the foot pedal. At this time, the first piston is affected by the movement of the second piston and moves, causing the first piston to pull the first end of the pull rope closer to the foot pedal. This, in turn, pulls the first end of the pull rope to connect to the internal transmission bracket, thereby opening the anti-contamination cover. During the movement of the first and second pistons, the deformation of the corresponding first and second springs increases. After the external force is removed, the first and second springs return to their original deformation, allowing the first and second pistons to return to their initial positions. Furthermore, by controlling the size of the opening, the movement of the second piston is disconnected from that of the first piston when the opening is open. Pressing the foot pedal will not cause the first piston to move, thus preventing the anti-contamination cover from opening. This avoids accidental opening of the anti-contamination cover when the paper dispensing device of this application is not used for a long time.

[0050] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
