Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] Reference Figure 1 , Figure 2 and Figure 3 The first embodiment of this application provides an oral cold test stick, including: a push handle 1, on which a pressing end and an output end are axially oppositely arranged, and a piston 12 is arranged on the output end; a tube 2, which has a hollow cavity structure, the push handle 1 is nested in the tube 2, and the output end abuts against the tube 2 through the piston 12.
[0029] The push handle 1 is nested inside the cavity of the tube 2. By pressing the pressing end of the push handle 1, the piston 12 at the output end inside the tube 2 is moved. The tube 2 is used to hold ice water or ice bars. The push handle 1 is tightly abutted against the inside of the tube 2 cavity by the piston 12, which can prevent ice water from flowing out from the connection between the push handle 1 and the tube 2. During the process of pressing the push handle 1, the piston 12 squeezes the ice water or ice bars, causing the ice water or ice bars to move in the same direction.
[0030] Specifically, when using the oral cold test stick for testing, the pressing end of the push handle 1 can be pressed to make the piston 12 squeeze the ice strip, and push the ice strip out from the inside of the tube 2 along the pressing direction to perform cold testing on specific locations or specific teeth of the patient, thereby improving the accuracy of cold testing and making it easier to find teeth with symptoms.
[0031] Meanwhile, the piston 12 is tightly abutted against the inside of the tube 2, so that after water is filled into the tube 2, the oral cavity cold test rod can be fixed vertically by the pressing end of the push handle 1 for freezing, and the water can be frozen into ice strips for cold testing.
[0032] This embodiment of an oral cold test stick includes a push handle 1 and a tube 2. The tube 2 has a hollow cavity structure. The output end of the push handle 1 is nested and abutted with the tube 2 through a piston 12, forming a tight connection. An ice strip can be placed inside the tube 2. By stretching the push handle 1, the ice strip extends from the other end of the tube 2, allowing the ice strip to contact a specific tooth of the patient for testing. At the same time, the piston 12 is tightly abutted with the tube 2, allowing water to be placed on the tube 2. The oral cold test stick is then placed vertically and fixed with the pressing end of the push handle 1 for freezing. After the water is frozen into an ice strip, the ice strip is used for cold testing. The operation is simple and convenient.
[0033] In some embodiments, the pressing end is provided with a handle head 11, the cross-sectional area of which is greater than or equal to the cross-sectional area of the push handle 1. In order to facilitate pressing the push handle 1, the cross-sectional area of the handle head 11 is preferably larger than the cross-sectional area of the push handle 1, so as to increase the force-bearing area and enable the user to push the push handle 1 with less force.
[0034] Furthermore, a connecting end and a testing end are axially oppositely arranged on the tube 2; an abutment 22 is provided on the connecting end, which is used to abut against the handle 11. The user can adjust the position of the piston 12 inside the cavity of the tube 2 by stretching the distance between the abutment 22 and the handle 11.
[0035] In some embodiments, the abutment member 22 is provided with a connection hole 221 corresponding to the output end, and the output end passes through the connection hole 221 to fit into the tube 2. Specifically, the cross-sectional area of the connection hole 221 is the same as the cross-sectional area of the piston 12, or the cross-sectional area of the connection hole 221 is slightly smaller than the cross-sectional area of the piston 12, so that the piston 12 can pass through the connection hole 221 to fit and connect the output end to the tube 2, while improving the tightness of the fit between the piston 12 and the inner wall of the tube 2, preventing water from seeping out from the connection between the piston 12 and the tube 2.
[0036] Furthermore, a limiting ring 13 is fitted onto the booster handle 1. The limiting ring 13 is located between the handle head 11 and the piston 12 and can engage with the connecting hole 221, thereby fixing the connection position between the booster handle 1 and the connecting hole 221, and thus stabilizing the position of the piston 12 inside the tube 2. Preferably, the limiting ring 13 is movable, and the connection position between the booster handle 1 and the connecting hole 221 can be fixed by pushing the limiting ring 13 to engage with the connecting hole 221.
[0037] Furthermore, a sealing ring 121 is provided on the piston 12, and the piston 12 abuts against the tube 2 through the sealing ring 121. The piston 12 is interference-fitted to the tube 2 through the sealing ring 121. The sealing ring 121 has a certain degree of elasticity, which can enhance the connection stability and sealing of the piston 12 and the tube 2, preventing water from leaking out from the connection between the piston 12 and the tube 2, and facilitating the freezing and ice-making of water in the oral cavity cold test stick. There can be multiple sealing rings 121, which can be set according to actual needs and sealing requirements. The spacing between adjacent sealing rings 121 can be the same, which facilitates the processing and manufacturing of the piston 12.
[0038] In some embodiments, the tube 2 is provided with a notch 21, the cross-section of which is arc-shaped; both sides of the notch 21 extend from the center away from the connecting end to connect with the test end. By rotating the oral cryoprobe, with the notch 21 positioned at the top, the upper part of the ice strip placed inside the tube 2 can be exposed through the notch 21 for cryoprobe testing of the patient. During this process, the inner wall of the tube 2 below the notch 21 supports the ice strip, providing support and preventing it from falling. Simultaneously, the test end of the tube 2 can be tilted upwards for use, preventing melted ice from flowing onto the patient and improving the patient's experience.
[0039] Furthermore, the outer side of the tube 2 is provided with a measuring scale, which allows a certain amount of water to be filled into the tube 2 for freezing according to the measuring scale, making it convenient for users.
[0040] Reference Figure 4 In some embodiments, the oral cryoprobe further includes a capping sleeve 3, which is fitted over the outside of the test end and is interference-fitted to the test end. When the capping sleeve 3 is closed with the test end, it forms a sealed ice-making space with the output end and the tube 2. The capping sleeve 3 is a hollow cavity that can be nested and closed with the test end. The ice-making space is used to hold water for freezing. After the capping sleeve 3 is closed with the test end, it can prevent the water in the tube 2 from leaking out, allowing the oral cryoprobe to be placed in a refrigerator or freezing device for freezing.
[0041] Furthermore, a sealing sticker can be used instead of the cap sleeve 3. Specifically, the oral cold test strip may also include a sealing sticker, which covers the test end and forms a sealed ice-making space with the output end and the tube 2. The sealing sticker can be made of adhesive plastic, which can adhere to and cover the test end to prevent water from seeping out, allowing the oral cold test strip to be placed in a refrigerator or freezer for freezing. The sealing sticker is also low in cost, easy to use, and can be used only once, preventing cross-infection of bacteria from repeated use.
[0042] Furthermore, the cover sleeve 3 is provided with an air hole 31. When the air hole 31 corresponds to the notch 21, the ice-making space is connected to the outside through the air hole 31. The air hole 31 facilitates gas exchange between the inside and outside of the ice-making space, preventing the cover sleeve 3 from being unable to open due to low air pressure inside the ice-making space after water solidifies into ice. Specifically, after placing the oral cold test stick in a refrigerator or freezing device, align the air hole 31 with the notch 21 to make the air pressure inside the ice-making space the same as the outside air pressure, and then the cover sleeve 3 can be directly removed for use. During placement, water should be prevented from flowing out through the air hole 31.
[0043] Furthermore, the outer side of the cover sleeve 3 is provided with a protrusion 32, which makes it convenient for the user to pick up the cover sleeve 3 and remove the cover sleeve 3 from the tube 2 based on the protrusion 32.
[0044] The push handle 1, tube 2, sealing tape, and cap sleeve of the oral cold test stick are all disposable items that can be discarded after use to prevent the risk of cross-infection of bacteria from repeated use; and all of them are made of odorless and freeze-resistant materials, which can be used for freezing operations to improve the user experience.
[0045] In summary, this application provides an oral cold test stick, including a push handle and a tube. The tube has a hollow cavity structure. The output end of the push handle is nested and abutted with the tube through a piston, forming a tight connection. An ice strip can be placed inside the tube. By stretching the push handle, the ice strip extends from the other end of the tube, allowing it to contact a specific tooth of the patient for testing. Simultaneously, the tight abutment between the piston and the tube allows water to be placed on the tube. The oral cold test stick is then placed vertically and fixed by the pressing end of the push handle for freezing. After the water is frozen into an ice strip, the ice strip is used for cold testing. The operation is simple and convenient.
