Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a speculum that prevents pinching injuries. Background Technology
[0002] A speculum is a device used to insert into a patient's vagina, open the vagina, and observe the cervix.
[0003] Existing speculum devices have the following problems during use:
[0004] 1. After the speculum is opened inside the patient's vagina, it is tightly wrapped by the vagina, causing the flesh on both sides of the vagina to be squeezed into the sides of the speculum along the opening. This results in the vaginal flesh being clamped and squeezed when the speculum is closed after use, causing pain and discomfort to the patient. Utility Model Content
[0005] In order to solve the above problems, the purpose of this utility model is to provide a speculum that prevents pinching injuries, which solves the problem that existing speculum will pinch and squeeze the vaginal flesh when closed, causing pain to the patient.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A speculum for preventing pinching injury includes a lower leaf, an upper leaf rotatably connected to the lower leaf at its rear, a grip handle fixed below the rear end of the lower leaf, a pressing handle fixed at the rear end of the upper leaf, a pair of first anti-pinch airbags respectively fixed on the left and right outer edges of the front part of the lower leaf, a pair of second anti-pinch airbags respectively fixed on the left and right outer edges of the front part of the upper leaf, and a pair of air supply components respectively fixed on the left and right sides between the grip handle and the pressing handle and used to inflate the first and second anti-pinch airbags.
[0008] Each air supply assembly includes an inflatable airbag fixedly mounted on the upper side of the grip handle, a three-way air supply pipe fixedly mounted on the inflatable airbag and used to connect the first anti-pinch airbag and the second anti-pinch airbag on the same side to the inflatable airbag, a pressing plate fixedly mounted on the lower side of the pressing handle and located above the inflatable airbag, and an exhaust sub-assembly mounted on the wall of the three-way air supply pipe and connected to the three-way air supply pipe and used to discharge the gas in the first anti-pinch airbag and the second anti-pinch airbag on the same side.
[0009] More preferably, each of the inflatable airbags has a one-way inflation valve on its sidewall for allowing gas to flow unidirectionally from the outside to the inside of the inflatable airbag, and a one-way valve for allowing gas to flow unidirectionally from the inflatable airbag to the three-way air pipe is fixedly installed inside each of the inflatable airbags at the connection point with the three-way air pipe.
[0010] More preferably, one end of the three-way air supply tube is fixedly connected to the inflatable airbag, one end passes through the inner wall of the corresponding side of the lower leaf and is fixedly connected to the first anti-pinch airbag on the corresponding side, and the other end passes through the inner wall of the corresponding side of the upper leaf and is fixedly connected to the second anti-pinch airbag on the corresponding side.
[0011] More preferably, the exhaust sub-assembly includes an exhaust pipe fixed to and connected to the three-way air supply pipe, and a removable sealing plug located in the end of the exhaust pipe away from the three-way air supply pipe.
[0012] This utility model has the following beneficial effects:
[0013] 1. This utility model solves the problem of vaginal pinching injury during the closure of the upper and lower leaves by pressing the handle towards the gripping handle, causing the press plate to continuously compress the inflatable airbags. The first and second anti-pinch airbags expand, pushing the vaginal tissue between the upper and lower leaves away from them. After use, pulling the handle away from the gripping handle causes the upper leaf to rotate downwards. During the closure process, the first and second anti-pinch airbags push the vaginal tissue away from the edges of the upper and lower leaves. Some tissue remains between the first and second anti-pinch airbags, but because they are made of flexible material, the tissue is not injured by compression.
[0014] 2. This utility model allows the anti-pinch airbag to be automatically inflated during the opening process by pressing the handle towards the gripping direction while the upper and lower leaves are rotating. After the upper and lower leaves are rotated to close, the gas inside the anti-pinch airbag is squeezed out along the exhaust pipe by removing the sealing plugs on both sides. Then, the sealing plugs on both sides are inserted into the corresponding exhaust pipe ports. This makes the product easy to operate and convenient for medical personnel to use.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, an anti-pinch speculum of this embodiment includes a lower leaf 1, an upper leaf 2 rotatably connected to the lower leaf 1 at its rear, a grip handle 3 fixed below the rear end of the lower leaf 1, a pressing handle 4 fixed at the rear end of the upper leaf 2, a pair of first anti-pinch airbags 5 respectively fixed on the outer edges of the left and right sides of the front part of the lower leaf 1, a pair of second anti-pinch airbags 6 respectively fixed on the outer edges of the left and right sides of the front part of the upper leaf 2, and a pair of air supply components 7 respectively fixed on the left and right sides between the grip handle 3 and the pressing handle 4 for inflating the first anti-pinch airbags 5 and the second anti-pinch airbags 6.
[0022] Each air supply assembly 7 includes an inflatable airbag 73 fixedly mounted on the upper side of the grip handle 3, a three-way air supply pipe 74 fixedly mounted on the inflatable airbag 73 and used to connect the first anti-pinch airbag 5 and the second anti-pinch airbag 6 on the same side to the inflatable airbag 73, a pressing plate 77 fixedly mounted on the lower side of the pressing handle 4 and located above the inflatable airbag 73, and an exhaust sub-assembly 76 provided on the wall of the three-way air supply pipe 74 and connected to the three-way air supply pipe 74 and used to exhaust the gas in the first anti-pinch airbag 5 and the second anti-pinch airbag 6 on the same side.
[0023] When using this product, insert the lower leaf 1 and the front part of the upper leaf 2 into the patient's vagina. Then, the medical staff presses the handle 4 towards the grip handle 3, causing the front part of the upper leaf 2 to rotate upward, thereby opening the vagina. As the handle 4 continues to move towards the grip handle 3, the pressing plate 77 continuously squeezes the inflatable airbag 73 towards the grip handle 3. This causes the gas inside the inflatable airbag 73 to flow through the one-way valve 732 along the three-way air inlet tube 74 into the first anti-pinch airbag 5 and the second anti-pinch airbag 6, causing the first anti-pinch airbag 5 and the second anti-pinch airbag 6 to continuously expand. This pushes the vaginal muscles on both sides away from the center of the upper leaf 2 and the lower leaf 1. After the examination, pull the handle 4 back, causing the upper leaf 2 to rotate downward, thereby gradually closing the telescopic plate 71. The first anti-pinch airbag 5 and the second anti-pinch airbag 6 expand and move closer together, pushing the vaginal flesh away from the telescopic plate 71. This allows the vaginal flesh to separate from the edges of the upper leaf 2 and the lower leaf 1, preventing it from being pinched. Some of the flesh remains between the first anti-pinch airbag 5 and the second anti-pinch airbag 6. Since the first anti-pinch airbag 5 and the second anti-pinch airbag 6 are made of flexible materials, they will not cause serious problems such as injury when held between them, thus preventing the vaginal flesh from being pinched. After the lower leaf 1 and the upper leaf 2 close, the exhaust component 76 is opened, causing the gas to be slowly squeezed out of the first anti-pinch airbag 5 and the second anti-pinch airbag 6 under the wrapping of the vagina. Then the device is removed.
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, each inflatable airbag 73 has a one-way inflation valve 731 on its side wall for allowing gas to flow unidirectionally from the outside to the inside of the inflatable airbag 73, and a one-way valve 732 is fixedly installed in the part of each inflatable airbag 73 that connects to the three-way air supply pipe 74 for allowing gas to flow unidirectionally from the inflatable airbag 73 to the three-way air supply pipe 74.
[0025] When this product is in use, as the pressing plate 75 continuously squeezes the inflatable airbag 73, the air inside the inflatable airbag 73 flows into the three-way air supply pipe 74 along the one-way valve 732, and is discharged into the first anti-pinch airbag 5 and the second anti-pinch airbag 6 through the three-way air supply pipe 74. After the upper leaf 2 and the lower leaf close, the pressing plate 75 disengages from squeezing the inflatable airbag 73, causing the inflatable airbag 73 to expand under its own elastic force, and drawing external gas into the inflatable airbag 73 along the one-way inflation valve 731, making it convenient for the next inflation.
[0026] like Figure 1 , Figure 2 and Figure 3As shown, one end of the three-way air supply tube 74 is fixedly connected to the inflatable airbag 73, the other end passes through the inner wall of the corresponding side of the lower leaf 1 and is fixedly connected to the first anti-pinch airbag 5 on the corresponding side, and the other end passes through the inner wall of the corresponding side of the upper leaf 2 and is fixedly connected to the second anti-pinch airbag 6 on the corresponding side.
[0027] When this product is in use, the three-way air supply pipe 74 that runs through the inner wall of the upper blade 2 and the lower blade 1 will not be squeezed by the upper blade 2 and the lower blade 1 during the rotation of the upper blade 2 and the lower blade 1, so as not to cause the problem of difficulty in air supply or jamming of the three-way air supply pipe 74.
[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the exhaust sub-assembly 76 includes an exhaust pipe 761 fixed to and connected to the three-way air supply pipe 74, and a sealing plug 762 detachably disposed in the end of the exhaust pipe 761 away from the three-way air supply pipe 74.
[0029] When using this product, if you can no longer pull and press the handle 4, pull out the sealing plug 762 at the port of the exhaust pipe 761 on both sides, and then continue to pull and press the handle 4. This will cause the gas in the anti-pinch airbag 72 to be expelled along the exhaust pipe 761 under the squeezing action of the upper leaf 2 and the lower leaf 1 until the upper leaf 2 and the lower leaf 1 are completely closed. Then, remove the front part of this device from the vagina to complete the use.
[0030] The working principle of this device is as follows:
[0031] Step 1: Insert the lower leaf 1 and the front part of the upper leaf 2 into the patient's vagina. Then, the medical staff will press the handle 4 towards the grip handle 3, causing the front part of the upper leaf 2 to rotate upward, thereby opening the vagina.
[0032] Step 2: As the upper leaf 2 rotates upward, the pressing handle 4 moves continuously toward the grip handle 3, causing the pressing plate 77 to continuously squeeze the inflatable airbag 73 toward the grip handle 3. This causes the gas in the inflatable airbag 73 to flow through the one-way valve 732 along the three-way air supply tube 74 into the first anti-pinch airbag 5 and the second anti-pinch airbag 6, causing the first anti-pinch airbag 5 and the second anti-pinch airbag 6 to continuously expand, pushing the vaginal muscles on both sides away from the center of the upper leaf 2 and the lower leaf 1.
[0033] Step 3: After the inspection is completed, pull the handle 4 back to make the upper leaf 2 rotate downwards, causing the first anti-pinch airbag 5 and the second anti-pinch airbag 6 to come into contact. This causes the first anti-pinch airbag 5 and the second anti-pinch airbag 6 to deform and expand away from the center of the upper leaf 2 and the lower leaf 1. As the upper leaf 2 and the lower leaf 1 close, the first anti-pinch airbag 5 and the second anti-pinch airbag 6 continuously expand outwards, thereby separating the vaginal flesh from the edges of the upper leaf 2 and the lower leaf 1 and preventing the vaginal flesh from being pinched.
[0034] Step 6: After the upper leaf 2 and lower leaf 1 are closed, pull out the sealing plugs 762 at the ports of the exhaust pipes 761 on both sides, and then continue to pull and press the handle 4 outward so that the gas in the first anti-pinch airbag 5 and the second anti-pinch airbag 6 is discharged along the exhaust pipe 761 after being compressed by the vaginal wrapping force, until the gas in the first anti-pinch airbag 5 and the second anti-pinch airbag 6 is completely discharged. Then remove the front part of the device from the vagina to complete the use.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
