Pedal support for medical devices

Abstract

This utility model aims to provide a foot pedal bracket for medical devices, including a base plate and a switch assembly. The base plate is integrally formed with a protrusion having a through hole. The switch assembly includes a rocker, a pedal, an elastic element, and a switch. The rocker is rotatably mounted within the protrusion. The elastic element and the switch are respectively disposed on two opposing inner sidewalls of the protrusion, and both are connected to the rocker. When the elastic element lifts one end of the rocker upward, it causes the other end of the rocker to press down on the switch. The pedal passes through the through hole and connects to the end of the rocker closest to the elastic element. When the pedal is under force, it moves the rocker away from the switch. This increases the service life of the foot switch, reducing the maintenance frequency of the medical device.

Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a pedal bracket for medical equipment. Background Technology

[0002] In the operation and control of modern medical equipment, foot switches, as important human-machine interface components, are widely used in various medical devices such as surgical instruments, rehabilitation equipment, and diagnostic instruments, undertaking key operational functions such as starting, stopping, and mode switching. Their stability and durability are directly related to the safety and continuity of medical operations, and are of great significance in ensuring the precision and efficiency of the medical process. For example, Chinese patent document CN109036890B discloses a safe and reliable medical foot switch, which includes a base, a button fixedly installed on the top wall of the base, a foot pedal rotatably connected to the upper side of the base, a fixing rod fixedly installed on the outer wall of one end of the foot pedal, a lead block connected to the bottom end of the fixing rod, a protective cover fixedly installed on the top wall of the base, a support device at the bottom end of the lead block, a positioning device connected to the outer wall of the lead block, the support device including a support plate, and multiple telescopic rods evenly installed on the top wall of the base. Each telescopic rod has a telescopic sub-rod inserted into its top wall, and the top ends of the sub-rods are fixedly installed on the bottom wall of the support plate. A second spring is wound around the outer wall of each sub-rod, and the two ends of the second spring are fixedly installed on the outer walls of the telescopic rod and the support plate, respectively. Thus, even if the spring elasticity deteriorates or fails, the lead block, by its own weight, will cause the foot pedal to return to its original position after the foot leaves the foot pedal.

[0003] However, existing medical foot switches have the following shortcomings in practical use: their buttons are located below the foot pedal and in front of the pivot. When the operator applies pressure to the foot pedal, the pedal rotates downwards around the pivot, and the button in front of the pivot directly bears the pressure from the foot pedal. Due to differences in operating habits and physical condition among different operators in medical settings, the pressure applied during pedaling often varies, or excessive pressure may occur in emergency situations. When the pressure exceeds the button's tolerance threshold, the foot pedal exerts strong pressure on the button. Prolonged or instantaneous excessive pressure can lead to contact deformation, spring fatigue fracture, and even irreversible damage such as switch housing cracking and internal circuit short circuits, further shortening the lifespan of the foot switch and increasing the maintenance frequency and cost of medical equipment. Therefore, this application proposes a foot pedal bracket for medical devices. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a foot switch bracket for medical devices that increases the service life of foot switches, thereby reducing the maintenance frequency and cost of medical devices.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A footrest bracket for a medical device, comprising:

[0007] The base plate, integrally formed with a protrusion, has a through hole in the protrusion; and

[0008] A switch assembly includes a rocker, a pedal, an elastic element, and a switch element. The rocker is rotatably disposed within the protrusion. The elastic element and the switch element are respectively disposed on two opposing inner sidewalls of the protrusion, and both the elastic element and the switch element are connected to the rocker. When the elastic element drives one end of the rocker to lift upward, the other end of the rocker presses down on the switch element. The pedal passes through the perforation to connect with the end of the rocker near the elastic element. When the pedal is subjected to force, it drives the rocker away from the switch element.

[0009] Optionally, the protrusion has a through hole inside, the rocker is rotatably disposed in the through hole, and the perforation communicates with the through hole.

[0010] Optionally, a hook block is provided on the inner wall of the through hole, a hook seat is provided on the rocker plate, and the two ends of the elastic element are respectively connected to the hook block and the hook seat.

[0011] Optionally, a groove is provided on the base plate, the groove is in communication with the through hole, and the pedal is located above the groove.

[0012] Optionally, the switch assembly further includes a buffer pad disposed on the inner sidewall of the perforation, the buffer pad being used to abut against the rocker.

[0013] Optionally, the pedal is provided with several anti-slip grooves.

[0014] Optionally, the switch assembly further includes a sealing plate disposed on the protrusion, the sealing plate being used to seal the through hole.

[0028] like Figures 1 to 4 As shown, in one embodiment, a footrest bracket 1 for a medical device includes a base plate 10 and a switch assembly. The base plate 10 is integrally formed with a protrusion 100, and a through hole 101 is provided on the protrusion 100. The switch assembly includes a rocker 20, a footrest 21, an elastic element 22, and a switch element 23. The rocker 20 is rotatably disposed within the protrusion 100. The elastic element 22 and the switch element 23 are respectively disposed on two opposing inner sidewalls of the protrusion 100, and both the elastic element 22 and the switch element 23 are connected to the rocker 20. When the elastic element 22 drives one end of the rocker 20 to lift upward, the other end of the rocker 20 presses down on the switch element 23. The footrest 21 passes through the through hole 101 to connect with the end of the rocker 20 near the elastic element 22. When the footrest 21 is subjected to force, it drives the rocker 20 away from the switch element 23.

[0029] It should be noted that a protrusion 100 is integrally formed on one end of the base plate 10. A through hole 101 is opened on the side of the protrusion 100 near the other end of the base plate 10. The rocker plate 20 is rotatably disposed in the protrusion 100. The elastic element 22 is a tension spring structure, and the switch element 23 is a limit switch structure. The elastic element 22 and the switch element 23 are respectively disposed on the two opposing inner sidewalls of the protrusion 100, with the elastic element 22 located on the inner sidewall of the protrusion 100 near the through hole 101, and the switch element 23 located on the inner sidewall of the protrusion 100 away from the through hole 101. Furthermore, the elastic element 22 is located above the rocker plate 20, and the switch element 23 is located below the rocker plate 20, so that the elastic element 22 and the switch element 23 are located on both sides of the rotation position of the rocker plate 20, with the rotation position of the rocker plate 20 as the center, and the elastic element 22 and the switch element 23 are respectively connected to the two ends of the rocker plate 20. Furthermore, one end of the elastic member 22 is connected to the inner wall of the protrusion 100, and the other end of the elastic member 22 is connected to the upper surface of the rocker 20 near the through hole 101. Thus, when the elastic member 22 pulls the rocker 20 to rotate relative to the protrusion 100, so that the end of the rocker 20 near the through hole 101 is lifted upward, the other end of the rocker 20 rotates downward to press the switch member 23.

[0030] It should be noted that the end of the rocker 20 furthest from the switch 23 passes through the perforation 101 and connects to the pedal 21. When the elastic element 22 lifts the end of the rocker 20 closest to the perforation 101, a portion of the rocker 20 swings upward to abut against the upper inner wall of the perforation 101, thereby limiting the upward rotation angle of the rocker 20 by the inner wall of the perforation 101. Thus, when the elastic element 22 pulls the rocker 20 to abut against the inner wall of the perforation 101, the minimum distance between the rocker 20 and the switch 23 is within the range that the pressing distance of the switch 23 can withstand.

[0031] It should be noted that when the operator presses the pedal 21 down, the pedal 21 will move downward to rotate the rocker 20 and stretch the tension spring. At the same time, it will move the other end of the rocker 20 away from the switch 23 to disengage from the press. After the switch 23 is disengaged from the press, the equipment will be activated (the switch connection method is press to disconnect and release to connect). When the rocker 20 moves away from the switch 23 under the action of the pedal 21, the switch 23 will be in the released state to connect the electrical signal. Thus, when different operators operate the device, regardless of the force applied to the pedal 21, the pedal 21 simply moves the rocker arm 20 away from the switch 23, preventing damage to the switch 23 even with excessive pressure. Furthermore, each time the operator releases their foot, the rocker arm 20 returns to the state of pressing the switch 23 under the elastic pull of the elastic element 22. Therefore, no matter how much pressure the pedal 21 receives, the elastic element 22 will pull the rocker arm 20 back to press the switch 23, preventing damage to the switch 23 due to excessive pressure. This improves the lifespan of the foot switch and reduces the maintenance frequency and cost of medical equipment.

[0032] In one embodiment, the elastic element 22 is disposed on the inner sidewall of the protrusion 100 near the through hole 101, and the elastic element 22 is located below the rocker arm 20. The elastic element 22 is a spring structure, and its two ends abut against the inner sidewall of the protrusion 100 and the hook ring, respectively. When the pedal 21 is subjected to a downward pressing force, it causes the rocker arm 20 to press down on the elastic element 22, while simultaneously causing the other end of the rocker arm 20 to move away from the switch element 23. Thus, no matter how much pressure is applied to the pedal 21, the elastic element 22 will push the rocker arm 20 back to press the switch element 23, thereby preventing the switch element 23 from being damaged by excessive pressure, thereby improving the service life of the foot switch and reducing the maintenance frequency and cost of the medical equipment.

[0033] like Figures 1 to 4 As shown, in one embodiment, a through hole 102 is provided inside the protrusion 100, the rocker plate 20 is rotatably disposed in the through hole 102, and the through hole 101 communicates with the through hole 102.

[0034] It should be noted that the through hole 102 penetrates the upper and lower end faces of the protrusion 100, thereby forming several inner sidewalls within the protrusion 100. Furthermore, the two opposing sides of the rocker 20 are rotatably connected to the two opposing inner sidewalls of the protrusion 100 adjacent to the through hole 101; the elastic member 22 is disposed on the inner sidewall of the protrusion 100 near the through hole 101, and the elastic member 22 is located above the rocker 20; the switch member 23 is disposed on the inner sidewall of the protrusion 100 away from the through hole 101, and the switch member 23 is located below the rocker 20.

[0035] like Figures 3 to 4As shown, in one embodiment, a hook block 1020 is provided on the inner sidewall of the through hole 102, a hook seat 201 is provided on the rocker plate 20, and the two ends of the elastic member 22 are respectively connected to the hook block 1020 and the hook seat 201.

[0036] It should be noted that a hook block 1020 is provided on the inner side wall of the through hole 102 near the perforation 101, and the hook block 1020 is located above the rocker 20; while a hook seat 201 is provided on the upper surface of the end of the rocker 20 near the perforation 101, and the two ends of the elastic member 22 are respectively connected to the hook block 1020 and the hook seat 201; the elastic member 22 pulls the end of the rocker 20 near the perforation 101 to rotate the inner side wall near the upper part of the perforation 101, and simultaneously drives the end of the rocker 20 away from the perforation 101 to press the switch member 23.

[0037] In one embodiment, a raised top groove 1021 is provided on the inner sidewall of the through hole 102 near the through hole 101, and the groove opening of the top groove 1021 faces the rocker plate 20. The top groove 1021 is located below the rocker plate 20. The two ends of the elastic member 22 abut against the lower surface of the end of the rocker plate 20 near the through hole 101 and the inner bottom wall of the top groove 1021, respectively. After the operator releases the pedal 21, the elastic member 22 pushes the end of the rocker plate 20 near the through hole 101 to abut against the upper inner sidewall of the through hole 101, and at the same time drives the end of the rocker plate 20 away from the through hole 101 to press down on the switch member 23.

[0038] like Figures 1 to 4 As shown, in one embodiment, a groove 103 is provided on the base plate 10, the groove 103 is connected to the through hole 101, and the pedal 21 is located above the groove 103.

[0039] It should be noted that the groove 103 is integrally formed on the base plate 10, and the groove 103 is close to the outer side of the protrusion 100 where the through hole 101 is formed, so that one end of the rocker 20 can pass through the through hole 101 and extend into the top of the groove 103; and one end of the pedal 21 is connected to the rocker 20, so that the pedal 21 can be located above the groove 103. When the operator steps on the pedal 21, the pedal 21 can be received in the groove 103; specifically, when the operator steps on the pedal 21 and it is received in the groove 103, the operator's foot will be on the base plate 10. In this way, the damage caused by long-term collision between the pedal 21 and the base plate 10 is reduced, thereby improving the service life of the foot switch and reducing the maintenance frequency and cost of the medical equipment.

[0040] like Figures 1 to 4 As shown, in one embodiment, the switch assembly further includes a buffer pad 24, which is disposed on the inner sidewall of the perforation 101 and is used to abut against the rocker 20.

[0041] It should be noted that the buffer pad 24 is located on the upper inner wall of the perforation 101. This prevents the rocker arm 20 from colliding violently with the inner wall of the perforation 101 when the elastic element 22 lifts the end of the rocker arm 20 closest to the perforation 101, thus avoiding damage to the rocker arm 20 or collapse of the upper inner wall of the perforation 101. It also reduces noise generated when the rocker arm 20 collides with the inner wall of the perforation 101, thereby improving the user's operating experience.

[0042] like Figures 1 to 4 As shown, in one embodiment, the pedal 21 is provided with a plurality of anti-slip grooves 210.

[0043] It should be noted that each anti-slip groove 210 is evenly spaced on the side of the pedal 21 away from the groove 103, in order to prevent the operator from slipping and making operational errors during the stepping process.

[0044] like Figures 1 to 4 As shown, in one embodiment, the switch assembly further includes a sealing plate 25, which is disposed on the protrusion 100 and is used to seal the through hole 102.

[0045] It should be noted that the sealing plate 25 is positioned above the protrusion 100 to seal the upper end of the through hole 102. For example, the sealing plate 25 is fixed to the protrusion 100 by screws. This prevents foreign objects from falling into the through hole 102 during use and jamming the rocker 20, the elastic element 22, and the switch element 23, which could damage the foot switch.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
