Description

Foot switch capable of preventing mistaken stepping safely

Technical Field

The utility model belongs to the technical field of electrical switches, and particularly relates to a pedal switch capable of preventing mistaken stepping safely.

Background

The foot switch is a switch for controlling the on-off of a circuit in a foot-stepping or treading mode, and is used in a control circuit which can not be touched by hands or is inconvenient to use the hands to replace the hands to achieve the operation purpose. In many medical devices, for example, MR (magnetic resonance), CT (computed tomography), etc., a foot switch is used for signal input. The foot switch is connected to the medical equipment, and when the relevant key of the foot switch is triggered, the corresponding control signal is transmitted to the control equipment through the foot switch and the connecting wire.

Due to the needs of medical equipment, foot switches are often provided with multiple pedals on their base plates, such as a dual pedal foot switch. Usually, the pedals are arranged in parallel, and the feet need to be switched left and right to trigger the pedal switch, so that some accidents of mistaken stepping on the pedal switch can occur, the reason may be that an operator usually uses hands and feet in combination during an operation, attention is not focused on actions under the feet, and in most cases, eyes need to consider the actions under the feet while observing the display equipment, so that the mistaken stepping on the pedals is difficult to avoid. The conventional method for preventing false triggering comprises the steps of arranging a protective cover at the periphery of a pedal switch so as to prevent false triggering caused by mistaken stepping and falling of foreign objects to a pedal; or the time delay is carried out by matching with software, for example, the corresponding operation is triggered only when the pedal is pressed for a certain time, and at the moment, if the mistaken stepping is carried out, the operator also finds the situation in time, and the correction operation can be carried out within the time delay period. However, the addition of the shield can only prevent an undesirable adverse force from outside the shield from being applied to the foot switch, but cannot avoid accidental stepping between adjacent pedals within the shield or within the same stepping space. Similarly, the delay setting still cannot completely avoid false triggering. For example, if the medical staff does not find the wrong stepping operation within the delay time period, the foot switch can still continue to execute the control command of the wrong stepping after the delay. For another example, when the medical staff switches between the left and right pedals, the medical staff mistakenly steps on the pedals or simultaneously steps on the two pedals to trigger an instruction mistakenly. In addition, because the protection casing is shell structure, medical personnel when operating foot switch, the shank front side collides with the protection casing easily, causes the shank injury.

The design of the existing foot pedal does not completely prevent the occurrence of false triggering events, which is extremely disadvantageous for medical devices with strict operational requirements and high safety, such as laser ablation devices, and poses a potential hazard for safe use of laser medical devices.

Therefore, it is necessary to design a safety false-stepping-prevention foot switch to overcome the disadvantages of the existing foot switch.

Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the utility model serve to explain the principles of the utility model and not to limit its scope.

As shown in FIG. 1, the present invention provides a safety anti-misstep foot switch, which is characterized in that the foot switch has a bottom plate 10, the bottom plate 10 is provided with pedals 30, the number n of the pedals 30 is greater than or equal to 2, n is a positive integer, for example, the number of the pedals may be 3, 4 or 6. The foot switch further comprises a protective cover 20 fixedly connected to the base plate 10, wherein the protective cover 20 and the base plate 10 define an operation space 50. Still further, the foot switch further comprises at least one spacer 40, the spacer 40 being disposed on the shield 20 and/or the base plate 10; more preferably, the partition body 40 is disposed between the adjacent pedal plates 30, that is, a partition body 40 is disposed between each adjacent pedal plate 30. The number of the partition bodies 40 may be determined according to the number of the pedals, for example, n of the pedals, and the number of the partition bodies 40 to be provided may be n-1, where n is a positive integer greater than 1. For example, when the number of the pedals 30 is 3, the partition bodies 40 are provided in a number of 2. The division bodies 40 divide the operation space 50 into a plurality of foothold spaces. Preferably, the number of the pedal spaces is the same as the number of the pedals, and more preferably, one pedal is correspondingly arranged in each pedal space. And the communication mode of the adjacent pedal spaces can be completely set to be partially communicated or not communicated completely or a mixed mode of the partial communication and the not communicated completely. The pedal positioning device has the advantages that each pedal is fixedly limited in the corresponding pedal space through the arrangement of the partition bodies, namely only one pedal can be stepped in each pedal space, so that the false triggering operation of a plurality of pedals in the same pedal space is avoided, and the stepping positioning is clearer and more definite.

The first embodiment is as follows:

the following description will be made in detail by taking only a two-pedal foot switch with the number of pedals being 2 as an example.

As shown in fig. 2A and 2B, the structure of the foot switch with two pedals is schematically illustrated. The dual pedal foot switch includes a base plate 10 and a shield 20. The base plate 10 and the shield 20 are fixedly coupled, and the base plate 10 and the shield 20 together define an operating space 50. 2 pedals 30 are provided on the floor panel 10 in the operating space 50. The dual-pedal foot switch further includes a partition 40, by which the operating space 50 is divided into a first foothold 100 and a second foothold 200 by the partition 40. And one pedal is respectively provided in the first pedal space 100 and the second pedal space 200. Further, the pedals comprise a left pedal 301 and a right pedal 302; the left pedal 301 is located in the first pedal space 100, and the right pedal 302 is located in the second pedal space 200.

The arrangement of the partition is flexible and the partition can be arranged on the protection cover 20 and/or the bottom plate 10. The way the separator is arranged is exemplified below.

The first situation is as follows: the separator may be provided only on the shield 20. Specifically, a separating body 40 extends downwards at the middle position of the protecting cover 20, and the separating body 40 can be a sheet body 402 or a U-shaped connecting body 401. As shown in FIG. 3A, a structure in which the partition body 40 is a U-shaped connection body is described. In detail, a U-shaped connection body 401 extends downward from the middle of the protection hood 20, and the U-shaped connection body 401 divides the operation space 50 into 2 foothold spaces. For another example, in fig. 3B, the partition may be a sheet 402 provided at a middle position of the protection cover 20, the sheet 402 dividing the operation space 50 into the first foothold 100 and the second foothold 200. The structural features of the sheet 402 are not limited herein. Further, a conversion gap (not shown) exists between the bottom of the U-shaped connecting body 401 or the bottom of the blade 402 and the bottom plate 10, and the height of the conversion gap is preferably larger than the height of the human foot, so that the feet of the operator can be flexibly switched between the two adjacent pedal spaces. The human foot of the utility model refers to a state without bare feet.

Case two: the separator can also be provided only on the base plate 10, as shown in fig. 3C. In this case two, the separating body 40 is a baffle 403, and the baffle 403 is disposed on the bottom plate 10. Preferably, the baffle 403 is disposed between the left pedal 301 and the right pedal 302, and the height of the baffle 403 is greater than the height of the left pedal 301 and the height of the right pedal 302. In this case two, the working space 50 is divided into a first footwell 100 and a second footwell 200 by means of the baffle 403. The left pedal 301 or the right pedal 302 is disposed in the first pedal space 100, and the right pedal 302 or the left pedal 301 is disposed in the second pedal space 200. Also, a transfer gap (not shown) is formed between the top of the shield 403 and the shield 20, preferably having a height greater than the height of the human foot, to facilitate flexible switching of the operator's feet between the adjacent two foot spaces.

Case three: the separator 40 is a first separator and/or a second separator, i.e., the separator 40 can comprise only the first separator or only the second separator or both the first separator and the second separator; wherein the first separator is a U-shaped connector 401, a sheet body 402 or a baffle 403; the second partition may also be a U-shaped connector 401 or a blade 402 or a baffle 403. Referring to fig. 4A and 4B, the separating body 40 includes a first separating body 40a and a second separating body 40B. The first partition 40a extends downwards from the middle of the inner top wall of the protective cover 20, and preferably, the first partition 40a is a U-shaped connecting body 401; the upper surface of the bottom plate 10 is provided with a second division body 40b at a position corresponding to the first division body 40a, the second division body 40b is a baffle 403, and the height of the baffle 403 is greater than that of the pedal. In the third case, the operating space 50 is divided into the first footwell 100 and the second footwell 200 by the arrangement of the U-shaped connecting body 401 and the baffle 403.

In the above cases one to three, the dual pedal foot switch comprises a base plate 10 and a protection cover 20; the base plate 10 and the shield 20 are fixedly coupled and define an operating space 50. 2 pedals 30 are arranged on the bottom plate 10 in the operation space 50 in parallel, namely, the protective cover 20 limits the pedals 30 in the operation space 50, so that undesired adverse acting force from the outside of the protective cover is blocked outside the operation space 50, and the mistaken stepping event of a foot switch by other people is avoided; furthermore, the operation space 50 is further divided into a plurality of pedal spaces by the partition 40, and preferably, only one pedal 30 is disposed in each pedal space, so as to ensure that an operator can only apply force to one pedal when performing a stepping action in one pedal space, thereby avoiding false triggering events such as mistaken stepping on a plurality of pedals at one time in the same pedal space.

Example two:

furthermore, in the foot switch with the number n of pedals being larger than or equal to 2, when the partition 40 partitions the operation space 50, the connection mode between the adjacent foot spaces may be various, such as a connection mode of partial connection or complete disconnection, or a combination of the above two. The following description is given by way of example.

The setting mode is as follows: referring to fig. 4A and 4B, the separation body 40 includes a first separation body 40a and a second separation body 40B. The first separator 40a is a U-shaped connector 401 or a plate 402. More specifically, the U-shaped connector 401 is disposed on the protective cover 20, and the protective cover 20 includes two arched bodies and one U-shaped connector 401; the U-shaped connector 401 connects the two arched bodies, respectively.

Referring to fig. 4A again, the second separation volume 40b is the baffle 403, and the baffle 403 is disposed on the upper surface of the bottom plate 10. More preferably, a transition space (not shown) is defined between the U-shaped connector 401 or the blade 402 and the baffle 403.

In the first configuration, the operation space 50 is divided into the first pedal space 100 and the second pedal space 200 by the first partition 40a, the second partition 40b and the switching gap, so that the operator can only step on one pedal in each pedal space, and false triggering events are greatly reduced. More preferably, in the first configuration, the height of the switching gap is preferably larger than the height of the human foot, and the first foothold 100 and the second foothold 200 are partially communicated with each other due to the switching gap, so that the operator can freely switch from the first foothold 100 to the second foothold 200.

The setting mode is two: referring to fig. 4B again, in the second embodiment, the separation body 40 includes a first separation body 40a and a second separation body 40B. Wherein the first separating body 40a is a U-shaped connecting body 401, and the second separating body 40b is the baffle 403. More preferably, the U-shaped connecting body 401 is fixedly connected with the baffle 403 to divide the operating space 50 into two completely independent footholds, namely a first foothold 100 and a second foothold 200.

In the second configuration, two adjacent pedal spaces are completely disconnected, that is, the first pedal space 100 and the second pedal space 200 are adjacently disposed but are independent from each other, only one pedal (for example, the left pedal 301 shown in fig. 4B) is disposed in the first pedal space 100, and only one pedal (for example, the right pedal 302 shown in fig. 4B) is disposed in the second pedal space 200. Compared with the prior art, each pedal space is provided with only one pedal, so that only one pedal can be operated or stepped on in the pedal space, and the phenomenon of stepping on dislocation in an emergency state is effectively prevented.

The setting mode is three: compared with the first setting mode and the second setting mode, the third setting mode is different in that the pedal spaces adjacent to each other in the operation space can be in a partially-communicated mode (the communicated mode in the first setting mode) or a completely-disconnected mode (the communicated mode in the second setting mode). Specifically, referring to fig. 5, the operation space 50 is partitioned into a first foothold 100, a second foothold 200 and a third foothold 300 which are adjacently arranged in this order. Wherein, the first pedal space 100 and the second pedal space 200 are partially communicated; the second foothold 200 and the third foothold 300 are completely disconnected from each other in an independent manner. The following examples are given by way of illustration III and specific examples.

Example three:

more preferably, according to the design idea of the present invention, the designer can flexibly set the layout of the pedal space of the foot switch according to the requirement of the operating device or the actual use requirement. For example, fig. 5 is a schematic view of a multi-pedal foot switch according to the present invention. The following description will be given taking the number of steps n as 3 as an example. The multi-pedal foot switch includes a base plate 10, a hood 20 and pedals. The protection cover 20 is fixedly connected with the base plate 10, and the protection cover 20 and the base plate 10 together define an operation space 50. 3 pedals including a first pedal 30a, a second pedal 30b and a third pedal 30c are arranged on the bottom plate 10 in the operation space 50 at intervals in parallel.

The multi-pedal foot switch further includes a first separator 40A and a second separator 40B, wherein the first separator 40A is disposed between the first pedal 30A and the second pedal 30B, and the second separator 40B is disposed between the second pedal 30B and the third pedal 30 c. More preferably, the arrangement of the first partition body 40A and the arrangement of the second partition body 40B are the same as those of the first and second embodiments, and are not repeated herein. Herein, the operation space 50 is divided into a plurality of footholds including a first foothold 100, a second foothold 200 and a third foothold 300 which are adjacently arranged in this order by the first and second partitions 40A and 40B. Further, the connection mode of each adjacent pedal space in the operating space 50 is partially connected or not connected or a combination of the above two.

Specifically, referring to fig. 5 again, only the first pedal 30a is disposed in the first pedal space 100, only the second pedal 30b is disposed in the second pedal space 200, and only the third pedal 30c is disposed in the third pedal space 300. More preferably, the first foothold 100 and the second foothold 200 are partially communicated with each other, and the second foothold 200 and the third foothold 300 are not communicated with each other. That is, the third footwell 300 is completely independent from the outside of the first and second footwells 100 and 200. The first and second footholds 100 and 200 are partially communicated with each other, so that the operator can flexibly switch between the first and second pedals 30a and 30 b. Of course, the first foothold 100 and the second foothold 200 may be completely disconnected from each other.

In the third embodiment, the partition bodies and the pedal space are flexibly and variously arranged and used, so that the use or various actual operation requirements of different equipment are met. For example, in a laser ablation device, the laser ablation device may adjust laser parameters of at least one of a laser power, a laser energy, a laser frequency, a pulse width, and an exit pattern of a laser. More preferably, the adjustment of the laser parameters is controlled by a foot pedal for the convenience of the operator. For example, one or more of the laser parameters may be adjusted by a first motion or series of motions of the first pedal 30 a; one or more of the laser parameters may be adjusted by a second motion or series of motions of the second pedal 30 b; one or more of the laser parameters may be adjusted by a third motion or series of motions of the third pedal 30 c. Therefore, in the present embodiment, different pedaling actions are applied to different pedaling spaces, the feet of the operator must extend into the pedaling space with corresponding pedaling actions, and only one pedal can be pedaled in the pedaling space, so that misoperation caused by pedaling in other directions can be prevented. Furthermore, before the laser ablation device is used, an operator can set the actions of the pedals, so that different execution results can be output after the actions are performed on the pedals, and the application range of the foot switch is enlarged.

Referring again to fig. 5, the first series of actions, the second series of actions, and the third series of actions may not be completely the same, and the operator may configure the actions as desired. More preferably, in a particular ablation operation, the laser light source has a first light source and a second light source. Wherein the first light source has the laser parameters, and tissue ablation is performed by adjusting the laser parameters. The second light source is typically used only before the first light source is activated, and is used to confirm or verify that the system light path is in normal operation. In this case, in order to better adjust the laser parameters of the first light source without accidentally activating the working state of the second light source during operation due to a mis-stepping action to affect the operation, it is more desirable for the operator to separate or divide the control of the second light source from the control action of the first light source. Thus, using the foot switch as shown in fig. 5, the control action of the second light source may be arranged on the third pedal 30c, and the control action of the first light source may be arranged on the first pedal 30a and/or the second pedal 30 b.

That is, the control action of the second light source will only take place within the third footspace 300; the control action of the first light source will only occur in the first pedal space 100 and/or the second pedal space 200, that is, the operator can divide each pedal into different pedal spaces according to the different sequence or times of use of each pedal or the different commands executed by the operator, and since there is only one pedal in each pedal space, the situation of different functional confusion caused by false triggering or accidental output of control commands will not occur. Therefore, an operator can reasonably arrange or divide each pedal and each pedal space according to the difference of the number, the functions or the effects and the like of different laser light sources and surgical instruments, so that different control actions are separated in the corresponding pedal spaces, or a certain pedal space with a special control action is independent of other pedal spaces or has few or one-time control actions, the operation safety is further improved, and the false triggering is effectively avoided.

Example four:

referring to fig. 4B and 6B together, the foot switch according to the present invention includes a cover 20, a pedal 30 and a base plate 10. The protection cover 20 and the base plate 10 are connected to form a first foothold 100 and a second foothold 200; the first foothold 100 and the second foothold 200 are partially communicated or not communicated at all; and a partition body 40 is formed at the communication. The base plate 10 has a plate body 101 and a surrounding wall 102, and the surrounding wall 102 is provided around three edges of the plate body 101. Preferably, the enclosure wall 102 comprises a first enclosure wall 102a, a second enclosure wall 102b, and a third enclosure wall 102 c. The first surrounding wall 102a and the second surrounding wall 102b are oppositely disposed on two sides of the board body 101, and the third surrounding wall 102c is respectively connected to the first surrounding wall 102a and the second surrounding wall 102 b. The protective cover 20 is fixedly connected to the base plate 10 through the first wall 102a, the second wall 102b and screws.

Further, the separation body 40 includes a first separation body 40a and a second separation body 40b, and the second separation body 40b may be connected to the third surrounding wall 102 c. In addition, the height of the wall 102 is not limited by the present invention. Preferably, the heights of the third wall 102c and the second partition 40b may be the same. The third surrounding wall 102c is arranged to prevent undesirable forces other than the third surrounding wall 102c from being applied to the pedal, so that only one foot of a user enters the foot pedal space, and the user can enter the foot pedal space from the foot pedal space to operate the foot pedal space, thereby effectively avoiding accidental pedaling of the pedal by other undesirable forces. The structural features of the spacer 40 are the same as those of the spacer 40 in the first to third embodiments, and are not described herein. In this embodiment, each component of the foot switch may be separately arranged or integrally arranged, which is not limited herein.

In addition, the utility model also provides a more preferable design in terms of usability and stability. For example, as shown in fig. 6A and 6B, the protective cover 20 is further provided with lower leg abdicating notches 201, and the number of the lower leg abdicating notches 201 can be matched with the number of the pedal spaces. The edge of the shank abdicating notch 201 is arc-shaped or circular or semi-elliptical, and the shank abdicating notch 201 is also provided with an anti-collision strip 202. The material of the anti-collision strip is preferably EVA (ethylene-vinyl acetate copolymer), the material has good water resistance and corrosion resistance, a closed cell structure, easy hot pressing, cutting, gluing, attaching and other processing, high resilience and tensile strength, high toughness, and good shock resistance and buffering performance. The shank abdication gap and the design of the anti-collision strip can avoid the condition that the front side of the shank collides with the edge of the protective cover to cause the shank to be injured when an operator operates a foot switch.

Referring to fig. 6A and 6B again, the bottom of the base plate 10 is further provided with an anti-slip device, such as an anti-slip foot pad 60. The material of the anti-skid foot pad 60 is preferably silica gel. The silica gel material has the advantages of skid resistance, softness and mildew resistance, and is very suitable for being used in hospitals in an environment with more liquid substances. The anti-slip foot pad 60 can increase the friction force between the foot switch and the ground, and the use stability of the foot switch is ensured.

In addition, the connection mode of each component of the foot switch, for example, the connection mode between the bottom plate and the protective cover, may be threaded connection, welding, bonding, etc., and these connection modes are all the prior art and are not described herein again. Meanwhile, the components may be integrally arranged or separately arranged, which is not limited herein.

It should be noted that, unless otherwise explicitly stated or limited, the term "connected" in the description of the various embodiments of the present invention is to be understood broadly, and for example, may be a fixed connection, a detachable connection, an integrated connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection via an intermediate medium. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
