Description

Technical Field

[0001] The present invention belongs to the technical field of oral medicine application devices, and particularly relates to an oral medicine application device. Background Art

[0002] There are two common oral medicine application devices that can be used by both doctors and patients in the prior art. The first is a cotton swab, and the second is a pair of forceps. The cotton swab includes a main rod and a cotton head fixed to the head of the main rod. The volume of the cotton head is usually not large. Due to the limited adsorption capacity of the cotton head, the amount of liquid medicine adsorbed at one time is usually insufficient, making it difficult to completely cover the affected area, and it is necessary to dip the medicine multiple times, which increases the complexity of the operation; if the same cotton swab is used to dip the medicine multiple times, the bacteria on the cotton head in contact with the affected area may contaminate the remaining medicine in the medicine bottle; in addition, the length and operation method of the cotton swab limit its use in deeper parts of the oral cavity.

[0003] The length of the forceps is longer than that of the cotton swab. Compared with the cotton swab, the forceps can reach deeper parts of the oral cavity, and the forceps can clamp a relatively large cotton ball, using the cotton ball to dip and absorb the required amount of liquid medicine for one-time application, without the need to dip the medicine multiple times, with convenient operation, and it will not cause contamination of the remaining medicine in the medicine bottle due to repeated dipping of the medicine. Therefore, the forceps can solve the use defects of the cotton swab. However, the forceps clamp the cotton ball by manual force, and the cotton ball is not fixed on the forceps. Moreover, the forceps in the prior art include two clamping arms, and the head end of each clamping arm for clamping an object is in a tip shape. There are only two clamping points between the tip and the cotton ball, which is prone to the problem of the cotton ball falling off. Since the volume of the cotton ball is relatively large and the adsorbed liquid medicine is also relatively much, if it falls off outside the patient's body, it will cause waste of medicine, and if it falls into the patient's oral cavity, it is easy to choke the patient.

[0004] In summary, it is necessary to change the existing structure of the forceps to achieve the purpose of preventing the cotton ball from falling off. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an oral medicine application device that is not prone to the cotton ball falling off.

[0006] The purpose of the present invention is to provide an oral medicine application device, which includes a first clamping arm and a second clamping arm. The tail ends of the first clamping arm and the second clamping arm are connected to form a forceps body. The head end of the second clamping arm includes two movable ends, and the positions of the movable ends are arranged opposite to the position of the head end of the first clamping arm. The two movable ends are rotatably connected to the head end of the second clamping arm, and an adjustment component is arranged on the two movable ends. The adjustment component is used to adjust the angle formed between the two movable ends, so that the two movable ends form an open state or a closed state. In the open state, the two movable ends are distributed in a V-shaped shape, and in the closed state, the head ends of the two movable ends are in contact.

[0007] Preferably, for the above oral medicine application device, when in the open state, the angle formed between the two movable ends is 25 degrees to 35 degrees.

[0008] Preferably, for the above oral medicine application device, the two movable ends are both triangular plates, and the head end of the second clamping arm is trapezoidal and matches the two movable ends. When the two movable ends are in the closed state, one side of the triangular plate coincides with one side of the trapezoid.

[0009] Preferably, for the above oral medicine application device, when the two movable ends are in the closed state, the head ends of the two movable ends form the tip of a wedge.

[0010] Preferably, for the above oral medicine application device, the two movable ends have the same structure and are symmetrically arranged up and down at the head end of the second clamping arm.

[0011] Preferably, for the above oral medicine application device, the space between the two movable ends is hollow or solid.

[0012] Preferably, for the above oral medicine application device, the adjustment component includes a first elastic sleeve. The first elastic sleeve has elasticity. When the two movable ends are in the closed state, the first elastic sleeve is sleeved outside the two movable ends. When the two movable ends are in the open state, the first elastic sleeve is sleeved on the second clamping arm.

[0013] Preferably, for the above oral medicine application device, the adjustment component includes a second elastic sleeve and a spring. A spring is arranged between the two movable ends. The second elastic sleeve has elasticity. When the two movable ends are in the closed state, the second elastic sleeve is sleeved outside the two movable ends. When the two movable ends are in the open state, the second elastic sleeve is sleeved on the second clamping arm.

[0014] Preferably, for the above oral medicine application device, the adjustment component includes a movable block. The movable block is slidably connected to the outer wall of the second clamping arm. There are two traction strips on the movable block. One end of one traction strip is rotatably connected to the movable block, and the other end is rotatably connected to the head end of one of the movable ends. One end of the other traction strip is rotatably connected to the movable block, and the other end is rotatably connected to the head end of the other movable end. When the two traction strips are in a V-shaped opening, the two movable ends are in the open state. When the two traction strips overlap, the two movable ends are in the closed state.

[0015] Preferably, for the above oral medicine application device, a limiting device is provided on the outer wall of the second clamping arm for limiting the position of the movable block.

[0016] Preferably, in the above oral drug application device, the limiting device includes a sliding groove. A rack is provided along the length direction of the second clamping arm at the bottom of the sliding groove. A gear is rotatably provided on the surface of the movable block facing the sliding groove. The gear is located above the rack and meshes with the rack. As the gear rotates, it can drive the movable block to rotate. One end of the gear facing away from the movable block is provided with an elastic capsule, and the elastic capsule contacts the upper and lower walls of the sliding groove to generate frictional force. In the absence of external force pushing, the power generated when the gear rotates automatically is less than the frictional force, so the automatic rotation of the gear can be blocked by using the obstruction of the frictional force, thereby achieving the effect of limiting the position of the movable block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The two movable ends of the present invention include an open state and a closed state. The area of the region surrounded by the two movable ends in the closed state is smaller than the area of the region surrounded by the two movable ends in the open state. Then, when the two movable ends are in the closed state, the contact space between the two movable ends, the head end of the first clamping arm, and the cotton ball is small. At this time, one cotton ball can be accurately picked up from many cotton balls. When the two movable ends are in the open state, the contact points of the two movable ends and the head end of the first clamping arm with the cotton ball respectively form a triangle. At this time, the stability of the triangle is good, and the contact space between the two movable ends, the head end of the first clamping arm, and the cotton ball is large, improving the clamping degree of the cotton ball and solving the problem that the cotton ball is easy to fall off. The flexibility of the device in use is high. In addition, the present invention also provides an adjustment component to adjust the angle formed by the two movable ends.

[0019] The embodiments of the present invention also list specific structures of several adjustment components. Those skilled in the art can also use other angle adjustment devices such as screws as adjustment components. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0036] The inventive concept of the present invention is as follows:

[0037] In the prior art, the volume of the cotton head of a cotton swab is usually not large, and the adsorption capacity of the cotton head is limited. Usually, the amount of liquid medicine adsorbed at one time is insufficient; compared with a cotton swab, forceps can reach deeper parts of the oral cavity, and forceps can pick up a larger cotton ball. The cotton ball can be used to dip up the required amount of liquid medicine for applying medicine at one time, and there is no need to dip the medicine multiple times. However, when the forceps pick up the cotton ball, the problem of the cotton ball falling off easily occurs.

[0038] For the above reasons, the present invention provides an oral medicine applying device, which includes a first clamping arm 1 and a second clamping arm 2. Both the first clamping arm 1 and the second clamping arm 2 have a head end and a tail end. The tail ends of the first clamping arm 1 and the second clamping arm 2 are connected to form a forceps body, and the tail ends of the first clamping arm 1 and the second clamping arm 2 are the positions for holding by hand; the head end of the second clamping arm 2 includes two movable ends 21, and the positions of the movable ends 21 are arranged opposite to the position of the head end of the first clamping arm 1. The two movable ends 21 and the head end of the first clamping arm 1 are used to contact and pick up the cotton ball; the movable ends 21 are rotatably connected to the head end of the second clamping arm 2, and an adjusting member 3 is arranged on the two movable ends 21. The adjusting member 3 is used to adjust the angle formed between the two movable ends 21 after picking up the cotton ball. Then, the two movable ends 21 and the head end of the first clamping arm 1 can enclose a triangular pyramid shape, and the contact points of the movable ends 21 and the head end of the first clamping arm 1 with the cotton ball form a triangle, and the stability of the triangle is good, which improves the clamping degree of the cotton ball.

[0039] The following will describe the detailed structure and working principle of the present invention in conjunction with specific embodiments.

[0040] Embodiment 1

[0041] An oral medicine applying device, referring to Figures 1 to 2 , includes a first clamping arm 1 and a second clamping arm 2. Both the first clamping arm 1 and the second clamping arm 2 have a head end and a tail end. The tail ends of the first clamping arm 1 and the second clamping arm 2 are connected to form a forceps body. The tail ends of the first clamping arm 1 and the second clamping arm 2 are the positions for holding by hand. Exemplarily, the tail ends of the first clamping arm 1 and the second clamping arm 2 are rotatably connected through a hinge or a rotating shaft, or the tail ends of the first clamping arm 1 and the second clamping arm 2 are fixedly connected by screws to facilitate the activities of the first clamping arm 1 and the second clamping arm 2. Exemplarily, both the first clamping arm 1 and the second clamping arm 2 are made of hard plastic material or stainless steel material. The connection manner between the first clamping arm 1 and the second clamping arm 2 can also refer to the connection relationship of the two clamping arms of other forceps in the prior art, as long as a structure that can form a "forceps body" for clamping objects can be formed, it is within the inventive concept scope of the present invention.

[0042] The head end of the second clamping arm 2 includes two movable ends 21. The positions of the two movable ends 21 are arranged opposite to the position of the head end of the first clamping arm 1. The two movable ends 21 and the head end of the first clamping arm 1 are used to contact and pick up cotton balls. The two movable ends 21 include an open state and a closed state. The open state refers to Figure 1 , the two movable ends 21 are distributed in a V-shaped configuration. The closed state refers to Figure 2 , the head ends of the two movable ends 21 are in contact. The area of the region surrounded by the two movable ends 21 in the closed state is smaller than the area of the region surrounded by the two movable ends 21 in the open state. Then, when the two movable ends 21 are in the closed state, the contact space between the two movable ends 21, the head end of the first clamping arm 1 and the cotton ball is small, which is similar to the structure of the tweezer with two clamping arms in the prior art. The contact points with the cotton ball are approximately two, and a straight line is formed between the two contact points. The principle of picking up the cotton ball at this time is shown in Figure 3 , and the stability is not strong. When the two movable ends 21 are in the open state, the contact points of the two movable ends 21 and the head end of the first clamping arm 1 with the cotton ball respectively form a triangle. The principle of picking up the cotton ball at this time is shown in Figure 4 . The triangle has good stability, which improves the clamping degree of the cotton ball and can solve the problem that the cotton ball is easy to fall off.

[0043] It should also be noted that in the actual scenario, the cotton balls used for dipping liquid medicine are usually packed together in multiple pieces and sold in the form of a bag of cotton balls. There is a slight adhesion between the cotton balls and it is not easy to distinguish them. The conversion of the two movable ends 21 designed in the present invention between the open state and the closed state also has the following advantages: that is, when picking up one cotton ball from many cotton balls, the two movable ends 21 are in the closed state. At this time, the tweezer has only two contact points with the cotton ball, and it will not accidentally pick up other cotton balls due to too many contact points. And at this time, it is also easy to insert the cotton ball into the medicine bottle to dip the liquid medicine. After the liquid medicine dipping is completed, the two movable ends 21 are converted to the open state. At this time, the clamping degree between the two movable ends 21 and the cotton ball increases, and the cotton ball is not easy to fall off during the process of transferring the cotton ball and applying the medicine.

[0044] Preferably, in the open state, when the angle formed between the two movable ends 21 is 25 degrees to 35 degrees, the cotton ball is most not easy to fall off.

[0045] Preferably, when the two movable ends 21 are in the closed state, the head ends of the two movable ends 21 form the tip of a wedge. Correspondingly, the head end of the first clamping arm 1 is also a tip, so as to easily pick out a certain cotton ball from many cotton balls.

[0046] Preferably, the two movable ends 21 are both triangular plates, and the head end of the second clamping arm 2 is a trapezoid matching the two movable ends 21. When the two movable ends 21 are in the closed state, one side of the triangular plate coincides with one side of the head end of the second clamping arm 2 to reduce the gap between the movable end 21 and the second clamping arm 2.

[0047] Preferably, when in the closed state, the space between the two movable ends 21 can be hollow or solid, and a suitable structure can be selected according to actual requirements.

[0048] Preferably, the two movable ends 21 have the same structure and are symmetrically arranged at the head end of the second clamping arm 2. The symmetrical movable ends 21 are convenient for adjusting the angle and are also beneficial to improving the stability when clamping the cotton ball.

[0049] The movable ends 21 are rotationally connected to the head end of the second clamping arm 2 through a rotating shaft. An adjusting member 3 is arranged on the two movable ends 21. The adjusting member 3 is used to adjust the angle formed between the two movable ends 21 after clamping the cotton ball, so that the two movable ends 21 are converted between the open state and the closed state.

[0050] The structure of the adjusting member 3 can be any of the following situations:

[0051] The first situation, referring to Figure 5 , the adjusting member 3 includes a first elastic sleeve 31. The first elastic sleeve 31 has elasticity and can be sleeved outside the two movable ends 21 and also on the second clamping arm 2. Moreover, when the first elastic sleeve 31 is sleeved outside the two movable ends 21, it can control the movable ends 21 to contact and form a closed state. At this time, a cotton ball can be easily picked out from many cotton balls with the tweezers of the present invention. Referring to Figure 6 , when the first elastic sleeve 31 is sleeved outside the second clamping arm 2, the external pressure on the two movable ends 21 is released, and the two are in an open state structure. To cooperate with this structure, the movable ends 21 can be made of a slightly bendable plastic structure with both elasticity and plasticity, and the first elastic sleeve 31 is a rubber sleeve.

[0052] The second situation, the adjusting member 3 includes a second elastic sleeve 301 and also a spring 32. In this case, the space between the two movable ends 21 is hollow, and a spring 32 is arranged between the two movable ends 21. The spring 32 can be a compression spring or a tension spring. The second elastic sleeve 301 has elasticity and can be sleeved outside the two movable ends 21 and also on the second clamping arm 2. Moreover, when the elastic sleeve 31 is sleeved outside the two movable ends 21, it can control the movable ends 21 to contact and form a closed state, see Figure 8 , at this time the spring 32 is in a compressed state. When the second elastic sleeve 301 is sleeved outside the second clamping arm 2, the external pressure on the two movable ends 21 is released, and the two are in an open state structure, see Figure 7 , at this time the spring 32 is in an extended state. During this process, the spring 32 and the second elastic sleeve 301 together limit the positions of the two movable ends 21. In this case, the movable ends 21 are triangular plates without elasticity.

[0053] In the third case, the adjustment member 3 includes a movable block 33 which is movably connected to the outer wall of the second clamping arm 2 to facilitate a person to control the sliding of the movable block 33. There are two traction bars 34 on the movable block 33. One end of one traction bar 34 is hinged to the movable block 33, and the other end is hinged to the head end of one of the movable ends 21. One end of the other traction bar 34 is hinged to the movable block 33, and the other end is hinged to the head end of the other movable end 21. As the movable block 33 slides, the two traction bars 34 open in a V shape. Correspondingly, the two movable ends 21 are in an open state. Refer to Figure 9 . The two traction bars 34 can also overlap to make the two movable ends 21 in a closed state. Refer to Figure 10 . Preferably, a limiting device is provided on the outer wall of the second clamping arm 2. The limiting device is used to limit the position of the movable block 33. Then the movable block 33 can be positioned at multiple places on the second clamping arm 2. Correspondingly, the angles of the two movable ends 21 can be multiple, and the flexibility of the device in use is high. In this case, the movable end 21 is a triangular plate without elasticity.

[0054] The limiting device refers to Figures 9 to 13 , and includes a chute 35 which is opened along the length direction of the second clamping arm 2. A rack 37 is provided on the inner bottom wall of the chute 35 along the length direction of the second clamping arm 2. One side of the movable block 33 facing the chute 35 is rotatably connected with a rotating shaft 39. The rotating shaft 39 can rotate along its own axial direction and can also rotate relative to the movable block 33. The other end of the rotating shaft 39 is connected to a gear 36. Preferably, the rotating shaft 39 and the gear 36 are fixedly connected. Then the gear 36 can rotate parallel to the movable block 33. The gear 36 is located above the rack 37 and the gear 36 meshes with the rack 37. As the gear 36 rotates, the movable block 33 can be driven to move along the length direction of the second clamping arm 2. In addition, an elastic capsule 38 is provided on the side of the gear 36 facing away from the movable block 33. Or, one end of a connecting shaft 391 is fixed to the side of the gear 36 facing away from the movable block 33, and the other end of the connecting shaft 391 is fixedly connected to the elastic capsule 38. The elastic capsule 38 contacts the upper and lower walls of the chute 35 to generate frictional force. When there is no external force to push, the power generated when the gear 36 rotates automatically is less than this frictional force. Then when there is no external force to push, the automatic rotation of the gear can be prevented by using the obstruction of the frictional force, so as to achieve the effect of limiting the position of the movable block. Therefore, when a person controls the movable block 33 and drives the gear 36 to rotate, due to the external force pushing, which is greater than the frictional force, the movable block 33 moves, and then drives the gear 36 to rotate and also drives the elastic capsule 38 to move. When a person does not control the movable block 33, the gear 36 stops moving, and the meshing effect and the frictional force make the movable block 33 unable to move independently. It should be noted that the movable block 33 made of plastic material, the gear 36 made of plastic material, the rack 37 made of plastic material and the elastic capsule 38 made of rubber material can meet the above working requirements. During production, multiple tests should be paid attention to in order to produce a limiting device that meets the above working requirements.
