The pressing structure achieves the effect of fixing the medicine bottle by inserting into the lower shell and abutting against the top surface of the medicine bottle.

[0004] However, due to the limited contact area of ​​the existing design when in contact with the bottle, the pressure distribution is uneven. When pressing the bottle, some areas bear excessive pressure, which can easily damage the bottle surface.

[0005] Therefore, how to avoid excessive pressure on the medicine bottle by the holding component is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] This disclosure provides at least one syringe to address the technical problem of excessive pressure applied to the vial by the pressure holder.

[0008] In a first aspect, embodiments of this disclosure provide a syringe, comprising: a lower housing having an internal cavity suitable for holding a medicine bottle; an upper housing having a insertion section at its bottom, the insertion section being suitable for connecting the upper housing and the lower housing; and a pressure-holding assembly disposed on the inner wall of the insertion section and abutting against the top surface of the medicine bottle; the pressure-holding assembly comprising: an L-shaped spring sheet disposed on both sides of the inner wall of the insertion section; and a vertical pressure-holding member disposed on the free end of the L-shaped spring sheet, the lower half of the vertical pressure-holding member being suspended outside the insertion section; wherein the insertion section is configured to be inserted into the lower housing, and the vertical pressure-holding member is suitable for applying vertical pressure to the top surface of the medicine bottle to fix the medicine bottle.

[0009] In one alternative embodiment, the vertical pressure holder is provided with at least one pressure relief notch that extends to the free end of the L-shaped spring.

[0010] In one optional embodiment, an arc-shaped connecting section is provided at the connection position between the L-shaped spring and the vertical pressure member.

[0011] In one optional embodiment, the bottom surface of the vertical pressing member is a plane or an arc-shaped surface, and the arc-shaped contour of the arc-shaped surface matches the contour of the top surface of the medicine bottle.

[0012] In one optional embodiment, the bottom surface of the vertical pressing member is provided with a plurality of protrusions, which are dot-shaped or strip-shaped.

[0013] In one alternative embodiment, there are at least two L-shaped spring clips, arranged at intervals along the inner wall of the insertion section.

[0014] Secondly, embodiments of this disclosure provide an upper housing for a syringe, comprising: a insertion section disposed at the bottom of the upper housing and adapted to connect the upper housing and a lower housing; a pressure-holding assembly disposed on the inner wall of the insertion section and abutting against the top surface of a vial; the pressure-holding assembly comprising: an L-shaped spring sheet disposed on both sides of the inner wall of the insertion section; and a vertical pressure-holding member disposed on the free end of the L-shaped spring sheet, the lower half of which is suspended outside the insertion section; wherein the insertion section is configured to be inserted into the lower housing, and the vertical pressure-holding member is adapted to apply vertical pressure to the top surface of the vial to fix the vial.

[0015] In one optional embodiment, the vertical pressure holding member is provided with at least one pressure relief notch, which extends to the free end of the L-shaped spring sheet; An arc-shaped connecting section is provided at the connection position between the L-shaped spring and the vertical pressure member.

[0016] In one optional embodiment, the bottom surface of the vertical pressing member is a plane or an arc-shaped surface, and the arc-shaped contour of the arc-shaped surface matches the contour of the top surface of the medicine bottle; the bottom surface of the vertical pressing member is provided with multiple protrusions, which are dot-shaped or strip-shaped.

[0017] Thirdly, this disclosure also provides a pressure-holding assembly for medicine bottles, including: an L-shaped spring sheet disposed on the inner wall of a connector section; a vertical pressure-holding member disposed on the free end of the L-shaped spring sheet, the lower half of the vertical pressure-holding member being suspended outside the connector section; the vertical pressure-holding member having at least one pressure relief notch extending to the free end of the L-shaped spring sheet; wherein the vertical pressure-holding member is adapted to apply vertical pressure to the top surface of the medicine bottle to fix the medicine bottle.

[0029] Research has revealed the following drawbacks of existing technologies: In related technologies, the syringe includes an upper shell and a lower shell, a portion of the upper shell is inserted into the lower shell, a medicine bottle is disposed within the lower shell, and a pressing structure for holding the medicine bottle is disposed within the upper shell. The pressing structure achieves the effect of fixing the medicine bottle by inserting itself into the lower shell and abutting against the top surface of the medicine bottle.

[0030] However, due to the limited contact area of ​​the existing design when in contact with the bottle, the pressure distribution is uneven. When pressing the bottle, some areas bear excessive pressure, which can easily damage the bottle surface.

[0031] Therefore, how to avoid excessive pressure on the medicine bottle by the holding component is a technical problem that urgently needs to be solved in this field.

[0032] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] like Figures 1 to 5 As shown, some embodiments provide a syringe, including: a lower housing 1, the internal cavity of which is suitable for placing a medicine bottle 3; an upper housing 2, the bottom of which is provided with a plug section 21, the plug section 21 being disposed at the bottom of the upper housing 2, the main function of the plug section 21 being to connect the upper housing 2 and the lower housing 1, specifically, by inserting the plug section 21 into the lower housing 1 to connect the upper housing 2 and the lower housing 1; a holding assembly 22 being disposed on the inner wall of the plug section 21, the holding assembly 22 being disposed on the inner wall of the plug section 21, after the plug section 21 is inserted into the lower housing 1, the holding assembly 22 abuts against the top surface of the medicine bottle 3 to achieve the effect of fixing the medicine bottle 3.

[0036] like Figures 2 to 4 As shown, the pressing assembly 22 includes an L-shaped spring piece 221, which is disposed on the inner wall of the insertion section 21. The L-shaped spring piece 221 is inserted into the lower housing 1 along with the insertion section 21 to achieve the effect of abutting against the top surface of the medicine bottle 3, thereby achieving the effect of vertically pressing and fixing the medicine bottle 3. It should be added that there are at least two L-shaped spring pieces 221, which are arranged at intervals along the inner wall of the insertion section 21.

[0037] Please see Figure 4The vertical holding member 222 is disposed on the free end 224 of the L-shaped spring piece 221. The lower half of the vertical holding member 222 is suspended outside the insertion section 21. The longer section of the L-shaped spring piece 221 has a free end 224. The vertical holding member 222 and the free end 224 are integrally connected to form a transverse "Z" shaped cross section. In addition, the turning position of the L-shaped spring piece 221 and the turning position where the vertical holding member 222 connects to the L-shaped spring piece 221 are both provided with chamfers. The forming multi-angle cross section of the holding assembly is more likely to deform when the pressure is too high, thus achieving a pressure relief effect.

[0038] Please see Figure 3 and combined Figure 4 The vertical holding member 222 is provided with at least one pressure relief notch 223. The main function of the pressure relief notch 223 is to allow the vertical holding member 222 to deform with the pressure when it is pressed against the medicine bottle 3. The deformation releases the extra pressure and effectively prevents the pressure from continuously increasing on the top surface of the medicine bottle 3. In other words, it allows the holding member 22 to deform. The pressure relief notch 223 extends to the free end 224 of the L-shaped spring piece 221. An arc-shaped connecting section 225 is provided at the connection position between the L-shaped spring piece 221 and the vertical holding member 222. Specifically, the pressure relief notch 223 is provided from the bottom surface of the vertical holding member 222 and extends to the lower half of the L-shaped spring piece 221.

[0039] As a preferred embodiment, in order to increase the stability when the top surface of the medicine bottle 3 is pressurized, the bottom surface of the vertical pressure member 222 is designed as a flat or curved surface. If the bottom surface is curved, the curved contour of the curved surface matches the contour of the top surface of the medicine bottle 3. In addition, in order to increase the friction, an anti-slip structure is provided on the bottom surface. Specifically, the bottom surface of the vertical pressure member 222 is provided with multiple protrusions, which are dot-shaped or strip-shaped.

[0040] like Figures 2 to 4 As shown, some embodiments provide an upper housing for a syringe, including: a plug section 21, which is disposed at the bottom of the upper housing 2. The main function of the plug section 21 is to connect the upper housing 2 and the lower housing 1. Specifically, the plug section 21 is inserted into the lower housing 1 to connect the upper housing 2 and the lower housing 1; and a holding assembly 22, which abuts against the top surface of the vial 3 after the plug section 21 extends into the lower housing 1 to fix the vial 3.

[0041] Please see Figure 4 The pressing component 22 includes an L-shaped spring piece 221, which is disposed on the inner wall of the insertion section 21. The L-shaped spring piece 221 is inserted into the lower housing 1 along with the insertion section 21 to achieve the effect of abutting against the top surface of the medicine bottle 3, thereby achieving the effect of vertically pressing and fixing the medicine bottle 3.

[0042] Please see Figure 4The vertical holding member 222 is disposed on the free end 224 of the L-shaped spring piece 221. The lower half of the vertical holding member 222 is suspended outside the insertion section 21. The longer section of the L-shaped spring piece 221 has a free end 224. The vertical holding member 222 and the free end 224 are integrally connected to form a transverse "Z" shaped cross section. In addition, the turning position of the L-shaped spring piece 221 and the turning position where the vertical holding member 222 connects to the L-shaped spring piece 221 are both provided with chamfers. The forming multi-angle cross section of the holding assembly is more likely to deform when the pressure is too high, thus achieving a pressure relief effect.

[0043] Please see Figure 3 and combined Figure 4 The vertical holding member 222 is provided with at least one pressure relief notch 223. The main function of the pressure relief notch 223 is to allow the vertical holding member 222 to deform with the pressure when it is pressed against the medicine bottle 3. The deformation releases the extra pressure and effectively prevents the pressure from continuously increasing on the top surface of the medicine bottle 3. In other words, it allows the holding member 22 to deform. The pressure relief notch 223 extends to the free end 224 of the L-shaped spring piece 221. An arc-shaped connecting section 225 is provided at the connection position between the L-shaped spring piece 221 and the vertical holding member 222. Specifically, the pressure relief notch 223 is provided from the bottom surface of the vertical holding member 222 and extends to the lower half of the L-shaped spring piece 221.

[0044] As a preferred embodiment, in order to increase the stability when the top surface of the medicine bottle 3 is pressurized, the bottom surface of the vertical pressure member 222 is designed as a flat or curved surface. If the bottom surface is curved, the curved contour of the curved surface matches the contour of the top surface of the medicine bottle 3. In addition, in order to increase the friction, an anti-slip structure is provided on the bottom surface. Specifically, the bottom surface of the vertical pressure member 222 is provided with multiple protrusions, which are dot-shaped or strip-shaped.

[0045] like Figures 3 to 4 As shown, some embodiments provide a pressure holding assembly for a medicine bottle, including: an L-shaped spring piece 221, which is disposed on the inner wall of the insertion section 21. The L-shaped spring piece 221 is inserted into the lower housing 1 along with the insertion section 21 to achieve the effect of abutting against the top surface of the medicine bottle 3, thereby achieving the effect of vertically pressing and fixing the medicine bottle 3.

[0046] Please see Figure 4The vertical holding member 222 is disposed on the free end 224 of the L-shaped spring piece 221. The lower half of the vertical holding member 222 is suspended outside the insertion section 21. The longer section of the L-shaped spring piece 221 has a free end 224. The vertical holding member 222 and the free end 224 are integrally connected to form a transverse "Z" shaped cross section. In addition, the turning position of the L-shaped spring piece 221 and the turning position where the vertical holding member 222 connects to the L-shaped spring piece 221 are both provided with chamfers. The forming multi-angle cross section of the holding assembly is more likely to deform when the pressure is too high, thus achieving a pressure relief effect. Please see Figure 3 and combined Figure 4 The vertical holding member 222 is provided with at least one pressure relief notch 223. The main function of the pressure relief notch 223 is to allow the vertical holding member 222 to deform with the pressure when it is pressed against the medicine bottle 3. The deformation releases the extra pressure and effectively prevents the pressure from continuously increasing on the top surface of the medicine bottle 3. In other words, it allows the holding member 22 to deform. The pressure relief notch 223 extends to the free end 224 of the L-shaped spring piece 221. An arc-shaped connecting section 225 is provided at the connection position between the L-shaped spring piece 221 and the vertical holding member 222. Specifically, the pressure relief notch 223 is provided from the bottom surface of the vertical holding member 222 and extends to the lower half of the L-shaped spring piece 221.

[0047] In summary, by setting an L-shaped spring piece 221 on the insertion section 21, the vertical pressing member 222 of its free end 224 extends into the lower housing 1 and abuts against the top surface of the medicine bottle 3 to fix the medicine bottle 3. Since the multi-segment pressing member formed by the L-shaped spring piece 221 and the vertical pressing member 222 has a large overall deformation, it avoids the phenomenon of excessive pressing force on the top surface of the medicine bottle 3 causing damage to the bottle. This not only improves the safety and reliability of the syringe, but also extends the service life of the medicine bottle 3.
