[0035] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0036] Please refer to Figure 10, it is to be noted that the insulin injection pen comprises a pen cap, a pen body and an injection head 8 installed on the pen body, wherein the pen body can be changed into different shapes, colors and capacities according to market demand, but the injection head 8 is a medical standard part, the structure of which is unchanged and can be adapted to various pen bodies, the pen body and the injection head 8 are connected by threads, and the injection head 8 is used as disposable consumables; further, the injection head 8 comprises a metal needle 81 arranged at the front end and a plurality of anti-skid grooves 82 arranged circumferentially along the outer wall; wherein the metal needle 81 is used for piercing the skin to inject insulin, and the anti-skid grooves 82 are used to increase the friction with the user's fingers, so that the user can tighten or loosen the injection head 8 on the pen body.

[0037] Please refer to Figures 1-5 The injection head 8 is shown in the figure, which comprises a preset unit 1, a clamping unit 2 and a control unit 3; wherein the preset unit 1 has a preset cavity 11 for placing the injection head 8; wherein the clamping unit 2 comprises two clamping pieces 21; the clamping unit 2 has a clamping cavity 22 surrounded by the two clamping pieces 21, when the injection head 8 enters the clamping cavity 22, the two clamping pieces 21 exert pressure on the side surface of the injection head 8; wherein the control unit 3 is arranged between the preset unit 1 and the clamping unit 2; the control unit 3 has a passageway 31 arranged in communication with the preset cavity 11 and the clamping cavity 22; the control unit 3 comprises two side plates 32 arranged on both sides of the passageway 31 and connected with the two clamping pieces 21 respectively; when the injection head 8 passes through the passageway 31, it extrudes the side plates 32, and the side plates 32 drive the clamping pieces 21 to deform, so that the clamping cavity 22 expands.

[0038] In actual use, the preset unit 1 of the utility model comprises a preset cavity 11, which is convenient for the user to hold the pen body of the insulin injection pen, and the injection head 8 is inserted into the preset cavity 11; the clamping unit 2 comprises two clamping pieces 21 and a clamping cavity 22, when the user holds the pen body of the insulin injection pen and moves the injection head 8 to the clamping cavity 22, the two clamping pieces 21 exert pressure on the side surface of the injection head 8, so that the injection head 8 is fixed, at this time, the user rotates the pen body, and the injection head 8 can be safely detached from the pen body without touching the injection head 8, thereby avoiding the user's hand being pricked by the injection head 8; the control unit 3 is arranged between the preset unit 1 and the clamping unit 2, and comprises a passageway 31 and two side plates 32, when the first injection head 8 is separated from the pen body in the clamping cavity 22, it is still clamped between the two clamping pieces 21, and when the second injection head 8 passes through the passageway 31, it extrudes the side plates 32, so that the side plates 32 drive the clamping pieces 21 to deform, and the clamping cavity 22 expands, thereby making the first injection head 8 automatically fall off from the clamping cavity 22.

[0039] Please continue to refer to Figure 2 , Figure 3 , Figure 4The preset unit 1 comprises an arc-shaped plate 13 and a first limiting plate 14 arranged at the bottom of the arc-shaped plate 13.

[0040] Specifically, when the user holds the pen body and places the used injection head 8 into the preset cavity 11 along the direction A, the height position of the injection head 8 is limited by the first limiting plate 14, so that the injection head 8 is always matched with the control unit 3 and the clamping unit 2 instead of the pen body during the subsequent movement of the control unit 3 and the clamping unit 2. The arc-shaped plate 13 provides a guiding effect for the injection head 8 and provides elastic force for the side plate 32 and the clamping piece 21 through the connection with the side plate 32 and the clamping piece 21.

[0041] Please continue to refer to Figure 3 、 Figure 4 The inner wall of the arc-shaped plate 13 is larger than the diameter of the injection head 8, and the first limiting plate 14 has a needle hole 141.

[0042] It can be understood that, in order to facilitate the user to insert the injection head 8 into the preset cavity 11, the inner wall of the arc-shaped plate 13 is larger than the diameter of the injection head 8, and the first limiting plate 14 has a needle hole 141. Through the arrangement of the needle hole 141, the main body of the injection head 8 is limited by the first limiting plate 14, and the metal needle 81 can pass through the needle hole 141, thereby ensuring the smooth implementation of the subsequent movement of the injection head 8.

[0043] Further, the connecting portion of the arc-shaped plate 13 and the first limiting plate 14 can be provided with a guide inclined surface. Through the arrangement of the guide inclined surface, the user can more conveniently insert the injection head 8 into the preset cavity 11, and the structural strength of the arc-shaped plate 13 is increased, thereby providing stronger elastic force for the side plate 32 and the clamping piece 21.

[0044] Please continue to refer to Figure 2 The preset unit 1 further comprises a side wing plate 15 arranged on the outer wall of the arc-shaped plate 13. The side wing plate 15 comprises at least two mounting portions 151, and the side wing plate 15 has two stress surfaces 152 located between the preset unit 1 and the control unit 3.

[0045] Specifically, when the insulin pen injection head is used alone, the user needs to press the insulin pen injection head with one hand and hold the pen body with the other hand to perform the dismounting operation of the injection head 8 due to the small weight. The arrangement of the two stress surfaces 152 on the side wing plate 15 provides a force point for the user to press the insulin pen injection head, so as to facilitate the smooth dismounting of the injection head 8.

[0046] It can be understood that the insulin pen injection head extrusion structure can be used in cooperation with other mechanisms, for example, the insulin pen injection head extrusion structure is fixed to the operation table through at least two mounting portions 151 on the side plate 15, so that the user can press the insulin pen injection head extrusion structure with one hand, and the extrusion of the injection head 8 is more smooth.

[0047] In addition, the side plate 15 is arranged along the outer wall of the arc-shaped plate 13, which is beneficial to strengthen the structural strength of the arc-shaped plate 13, so as to provide stronger elastic force for the side plate 32 and the clamping piece 21.

[0048] Please continue to refer to Figure 2 、 Figure 5 , wherein the side plate 32 comprises an inclined top portion 321 protruding towards the passage 31; the inclined top portion 321 is arranged to gradually increase the protruding degree from the preset cavity 11 to the clamping cavity 22.

[0049] Specifically, through the arrangement of the inclined top portion 321, when the injection head 8 passes through the passage 31, the side plate 32 on both sides is pressed to move towards both sides, and then the side plate 32 drives the two clamping pieces 21 to move towards both sides, so that the clamping cavity 22 is expanded; when the clamping cavity 22 is expanded, if an injection head 8 has been clamped in the clamping cavity 22, the injection head 8 will naturally fall off, so that the previous injection head 8 can be smoothly taken off, and the space in the clamping cavity 22 is also provided for the smooth extrusion of the next injection head 8; the inclined top portion 321 is arranged to gradually increase the protruding degree from the preset cavity 11 to the clamping cavity 22, which not only provides a guiding function, but also makes the expansion degree of the clamping cavity 22 maximum when the injection head 8 is at the critical position of the clamping cavity 22 and the passage 31, so as to ensure that the previous injection head 8 has fallen off when the next injection head 8 enters the clamping cavity 22.

[0050] Please continue to refer to Figure 2 , wherein the control unit 3 further comprises a second limiting plate 33 arranged at the bottom of the side plate 32.

[0051] It can be understood that the second limiting plate 33 is arranged to be connected with the first limiting plate 14, and continues to limit the height position of the injection head 8, so as to ensure that the injection head 8 enters the clamping cavity 22, rather than the pen body; further, the second limiting plate 33 between the two sides leaves a slot, which is used to ensure the smooth movement of the metal needle 81.

[0052] Please continue to refer to Figure 2 , Figure 3 , wherein the clamping piece 21 comprises a plurality of clamping strips 211 arranged on the inner wall; the clamping cavity 22 is arranged to have a size smaller than the diameter of the injection head 8 in a normal state.

[0053] It can be understood that the clamping cavity 22 is arranged to be smaller in size than the diameter of the injection head 8 in normal state, so as to exert a greater elastic force on the side wall of the injection head 8 in the clamping cavity 22; and since the aforementioned injection head 8 comprises a plurality of anti-skid grooves 82 arranged circumferentially along the outer wall, the plurality of clamping strips 211 of the inner wall of the clamping piece 21 can be embedded in the anti-skid grooves 82, and when the user twists the pen body, the user can conveniently unscrew the injection head 8 due to the mutual engagement of the plurality of clamping strips 211 and the anti-skid grooves 82.

[0054] Please continue to refer to Figure 4 , further comprising a raised portion 4, wherein the raised portion 4 is arranged at at least one of the preset unit 1 and the control unit 3; the raised portion 4 is used to raise the distance between the preset unit 1 or the control unit 3 and the placement surface.

[0055] It can be understood that in some working conditions, although the metal needle 81 can pass through the needle passing hole 141, it is still possible to interfere with the placement surface below the preset unit 1 or the control unit 3, causing the injection head 8 to be unable to enter the preset unit 1; by arranging the raised portion 4, the distance between the preset unit 1 or the control unit 3 and the placement surface is increased, thereby avoiding the interference between the metal needle 81 and the placement surface below.

[0056] Please refer to Figures 6-9 The sharpener box shown in the figure, the aforementioned insulin pen injection head extraction structure further comprises a box body 5, a box cover 6 and a rotating cover 7; wherein the box cover 6 is arranged on the box body 5; the side wing plate 15 is arranged on the box cover 6; wherein the rotating cover 7 is arranged to be rotatably connected to the upper end surface of the box cover 6.

[0057] In actual use, since the injection head 8 is a medical sharp, it needs to be placed in the sharpener box for unified treatment after use, and when the insulin pen injection head extraction structure is arranged on the box cover 6 through the side wing plate 15, the injection head 8 extracted from the insulin pen injection head extraction structure can directly enter the box body 5 without manual handling by the user, which not only saves steps, but also avoids the risk of being pricked by hand.

[0058] Please continue to refer to Figure 7 , Figure 8 , Figure 9 , wherein the box cover 6 comprises at least two connecting portions 61; the connecting portion 61 is arranged to cooperate with the mounting portion 151; the box cover 6 has a first sharpener insertion port 62 and a second sharpener insertion port 63; the preset unit 1, the clamping unit 2 and the control unit 3 are arranged in the second sharpener insertion port 63; the rotating cover 7 is arranged to control the opening and closing of the first sharpener insertion port 62 and the second sharpener insertion port 63 by rotating.

[0059] Specifically, by the cooperation of the multiple sets of connecting portions 61 and the mounting portion 151, the connection between the insulin pen injection head ejection structure and the box cover 6 is more firm; when the user needs to place the injection head 8, only needs to hold the pen body to insert the injection head 8 into the preset cavity 11 from the second weapon throwing port 63, and then pass the injection head 8 into the clamping cavity 22 along B through the passageway 31, so that the injection head 8 can be screwed off in the clamping cavity 22; if there is already an injection head 8 in the clamping cavity 22, the next injection head 8 will fall into the box body 5 along C when passing through the passageway 31.

[0060] It is worth mentioning that when the user needs to place other weapons, it can be thrown through the first weapon throwing port 62; and the first weapon throwing port 62 and the second weapon throwing port 63 are arranged on one side of the box cover 6, so that when the cap 7 is rotated, both of them are covered, and the weapons are prevented from falling out of any one of the first weapon throwing port 62 and the second weapon throwing port 63 during transportation.

[0061] The above only describes the best embodiment of the utility model, but cannot be understood as a limitation on the claims. The utility model is not limited to the above embodiments, and the specific structure can be changed. Any change within the protection scope of the independent claims of the utility model is within the protection scope of the utility model.
