Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a gear-shift pedal type cerumen washing device. Background Art

[0002] Currently, the usual way to deal with earwax in hospitals is to first soften the stubborn earwax with a sodium bicarbonate solution, and then use a flushing device (such as an airbag assembly) to drive the liquid to form hydraulic pressure to flush in the ear, thereby causing the softened earwax to fall off.

[0003] In the prior art, in order to avoid medical staff's hands being occupied at the same time (the hands usually grasp the hose head and squeeze the air bag respectively) and affecting other operating procedures (such as stabilizing the affected area, taking other instruments, etc.), a foot-operated flushing device has been developed. The air bag is squeezed by stepping on the pedal to discharge the medicine to free the hands.

[0004] However, the flushing device needs to use different hydraulic flushing for different patient groups. For example, for young children or patients with ear diseases, the hydraulic level formed by squeezing the airbag cannot be too high. Compared with manually squeezing the airbag, the pedal-type flushing device is not precise and stable enough to control by the foot, which can easily reach the full output of the airbag and form the highest hydraulic pressure, which can easily cause discomfort or even secondary injury to the patient. Utility Model Content

[0005] The utility model aims to provide a shift pedal type cerumen washing device to solve the technical problem in the prior art that the foot pedal is not sensitive and accurate enough, thus easily triggering the full output of the airbag, causing excessive hydraulic pressure and causing discomfort to the patient.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A shift-pedal type cerumen flushing device, comprising a drug flow pipeline, the drug flow pipeline is provided with a liquid storage cavity and a balloon body, a shift-pedal assembly is provided outside the balloon body, the shift-pedal assembly comprises a bottom plate, an active pedal is rotatably mounted on the bottom plate, and the balloon body is provided between the active pedal and the bottom plate;

[0008] Side plates are arranged on both sides of the bottom plate, and arc-shaped through-holes are opened on the side plates. The side of the active pedal passes through a connecting column, and the connecting column is slidably installed in the arc-shaped through-hole in a manner that the end of the connecting column passes through the arc-shaped through-hole;

[0009] A plurality of limiting holes are arranged on the surface of the side panel above the arcuate perforation, and an arcuate slide groove is arranged on the surface of the side panel below the arcuate perforation. A limiting member is slidably installed in the arcuate slide groove, and the limiting member slides in the arcuate slide groove in a manner of fitting the surface of the side panel, and the other end of the limiting member is embedded in the limiting hole to fix the position of the limiting member.

[0010] As a preferred solution of the utility model, an acute-angle motion cavity is formed between the active pedal and the base plate, and an elastic reset member is arranged in the acute-angle motion cavity, and the elastic reset member is respectively connected to the active pedal and the base plate.

[0011] As a preferred solution of the utility model, an earmuff container is provided at one end of the drug flow conduit close to the liquid outlet, a sealing component is provided on the opening of the earmuff container, the earmuff container is fitted around the ear through the sealing component, at least one fixed connecting belt is provided on the earmuff container, and both ends of the fixed connecting belt are connected to the earmuff container and enclosed to form an annular frame that is sleeved on the patient's head.

[0012] As a preferred solution of the utility model, a main support rod body is arranged outside the earmuff container, and a base is arranged at the other end of the main support rod body.

[0013] As a preferred solution of the utility model, an outward-expanding base is provided at the end of the main support rod body, and the earmuff container is detachably arranged on the outward-expanding base.

[0014] As a preferred solution of the present invention, the earmuff container and the outwardly extending base are both made of a transparent shell.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model sets a limiter on the outside of the active pedal, and limits the rebound angle of the active pedal and the filling degree of the balloon body by artificially setting an upper limit, thereby limiting the output pressure of the balloon body and controlling the hydraulic level of the liquid flow into the ear. When the foot steps on the pedal to squeeze the balloon, the balloon body will not be over-expanded and then fully loaded due to the high angle of the foot lifting, forming the highest hydraulic pressure, causing excessive impact on the ear.

[0017] At the same time, by adjusting the position of the limiter, the filling degree of the balloon can be adjusted laterally, thereby adjusting the specific output pressure, making the device more flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 3 As shown, the utility model provides a shift pedal type cerumen flushing device, including a drug flow pipeline 1, on which a liquid storage chamber 2 and a balloon body 3 are arranged, and a shift pedal assembly 4 is arranged outside the balloon body 3. The shift pedal assembly 4 includes a base plate 5, on which an active pedal 6 is rotatably mounted, and the balloon body 3 is arranged between the active pedal 6 and the base plate 5.

[0026] Side plates 7 are provided on both sides of the bottom plate 5 , and arc-shaped through holes 8 are opened on the side plates 7 . The side of the active pedal 6 passes through a connecting column 9 , and the connecting column 9 is slidably installed in the arc-shaped through hole 8 in a manner that the end of the connecting column 9 passes through the arc-shaped through hole 8 .

[0027] A plurality of limiting holes 10 are provided on the surface of the side plate 7 above the arcuate perforation 8, and an arcuate slide groove 11 is provided on the surface of the side plate 7 below the arcuate perforation 8. A limiting member 12 is slidably installed in the arcuate slide groove 11, and the limiting member 12 slides in the arcuate slide groove 11 in a manner of fitting the surface of the side plate 7, and the other end of the limiting member 12 is embedded in the limiting hole 10 to fix the position of the limiting member 12.

[0028] In the present device, the balloon body 3 is arranged between the active pedal 6 and the base plate 5, and is connected to the medicine liquid tube. The balloon body 3 itself may be provided with at least one one-way valve capable of inhaling air inwards, and a one-way valve capable of exhausting air outwards is provided at the position in communication with the medicine liquid tube. In this way, when the balloon body 3 is squeezed, the balloon body 3 cannot exhaust air outwards from its two one-way valves that can only take in air, and can only exhaust air into the medicine liquid tube, thereby pushing the medicine in the medicine liquid tube to be discharged from the liquid outlet into the ear for flushing. When the balloon body 3 is released and the balloon body 3 is restored, it cannot inhale air from the one-way valve on the medicine liquid tube that can only exhaust air, so it can only inhale air from the outside through its own one-way valve to complete the filling process, which is the best preparation for the next exhaust, and the flushing process is repeated in this way.

[0029] Among them, Figure 2 As shown, the setting of the limiter 12 is to set an upper limit for the expansion of the balloon body 3. For example, when the infant patient does not need the balloon body 3 to fully expand and output pressure, the limiter 12 is adjusted to the right, so that the active pedal 6 cannot return to the normal tilt level, and the angle between the active pedal 6 and the bottom plate 5 is reduced. At this time, the elastic reset member 13 is at a compressed level, and the balloon body 3 is also at a compressed level and cannot rebound to its maximum filling level. At this time, squeezing the balloon again can slow down the liquid flow speed and reduce the hydraulic pressure.

[0030] Among them, the setting of the limiter 12 is slidably installed in the arc-shaped slide groove 11. It slides against the surface of the side plate 7, and the connecting column 9 protrudes from the arc-shaped through hole 8, which makes the part of the connecting column 9 protruding from the arc-shaped through hole 8 must be blocked by the limiter 12, thereby forming a limit.

[0031] In addition, as an embodiment, the stopper 12 can be set to a retractable structure, which stretches its end away from the stopper hole 10, then slides in the arc-shaped slide groove 11, reaches the designated stopper hole 10, and is compressed and inserted into the stopper hole 10 to form a stopper. Alternatively, the stopper 12 can be a rotating structure, which rotates its end away from the stopper hole 10, waits until it slides to the designated stopper hole 10, and then rotates back to embed into the stopper hole 10 to complete the stopper.

[0032] Further, such as Figure 3As shown, an acute-angle motion cavity is formed between the active pedal 6 and the base plate 5 , and an elastic reset member 13 is arranged in the acute-angle motion cavity. The elastic reset member 13 is connected to the active pedal 6 and the base plate 5 respectively.

[0033] In addition, since the flushing of the drug solution will cause the outflow of waste liquid, the traditional way of receiving the waste liquid is that the patient actively holds the receiving container under the ear to receive it. In order to facilitate use and reduce the patient's labor, a container with an earmuff is further designed. The container is provided at the port of the drug flow channel 1, and the earmuff is provided around the ear when in use, so as to receive the waste liquid after flushing.

[0034] However, traditional earmuffs require the cooperation of the patient and the doctor to apply force together to tightly seal the earmuffs around the ear, which is still not convenient enough.

[0035] Therefore, the device is provided with an earmuff container 14 at one end of the drug flow pipe 1 close to the liquid outlet, and a sealing component is provided on the opening of the earmuff container 14. The earmuff container 14 is fitted around the ear through the sealing component, and at least one fixed connecting belt 15 is provided on the earmuff container 14. Both ends of the fixed connecting belt 15 are connected to the earmuff container 14 and enclosed to form an annular frame that is sleeved on the patient's head.

[0036] The sealing component can be a sealing strip, a sealing adhesive or other component that can fit around the ear, and then the earmuff container 14 is fixedly connected to the patient's ear through a fixed connecting belt 15, so that there is no need for the doctor and the patient to cooperate in fixing the container, making it more convenient to use.

[0037] In addition, the earmuff container 14 can be configured as a container with a small opening, light weight, and a large volume, so as to have the functions of high sealing, easy wearing, and accommodating more waste liquid.

[0038] Furthermore, the waste liquid increased by continuous flushing will increase the weight of the earmuff container 14, so a main support rod 16 is provided outside the earmuff container 14, and a base is provided at the other end of the main support rod 16. The earmuff container 14 is supported from the bottom by the main support rod 16 to reduce the fatigue of the patient supporting it alone.

[0039] Further, such as Figure 1 As shown, the end of the main support rod 16 can be designed with an outward-expanding bottom support 17, and the earmuff container 14 is detachably arranged on the outward-expanding bottom support 17. The outward-expanding bottom support 17 receives the earmuff container 14, so that the earmuff container 14 is placed on the main support rod 16 more stably and does not shake. In this regard, the outward-expanding bottom support 17 can be set as an arc-shaped bowl-shaped structure to wrap and stabilize the earmuff container 14, and the earmuff container 14 is directly placed in the outward-expanding bottom support 17, so that it plays a supporting role and is not troublesome when disassembling.

[0040] In practical application, in another embodiment, the earmuff container 14 can be set smaller, and then connected to the liquid storage tank on the bottom surface through the drainage tube, so that the waste liquid in the earmuff container 14 is drained into the liquid storage tank, so that there is no need for a supporting structure to support the larger earmuff container 14. However, the purpose of such a setting in this device is that the drainage tube needs to be cleaned after use, and the earwax fragments in the waste liquid have the risk of clogging the drainage tube. Therefore, in order to prevent the complicated flushing of the long drainage tube and the waste of resources caused by clogging the drainage tube, this device chooses to use the outer bottom support 17 and the main support rod body 16 to support the earmuff container 14. In this way, the outer bottom support 17 and the main support rod body 16, as independent components that do not contact the waste liquid, will not be contaminated, and only the earmuff container 14 needs to be cleaned. And the outer bottom support 17 and the main support rod body 16 as independent components can also be used separately according to the specific needs of the hospital.

[0041] In addition, the earmuff container 14 and the outer bottom support 17 are both made of a transparent shell, so that the content of earwax fragments in the waste liquid can be observed from the outside, thereby judging the effect of earwax flushing.

[0042] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
