Description

Technical Field

[0001] This invention relates to the field of pharmaceutical extraction technology, and more specifically to a portable pharmaceutical liquid extraction device. Background Technology

[0002] The compartments, passageways, and medical stations inside ships are very compact, requiring equipment to be miniaturized and integrated. Ships are constantly in a state of rocking, tilting, or even severe turbulence while sailing (especially in rough seas).

[0003] In response to potential combat injuries or sudden emergencies, medics (military doctors) are required to be able to respond quickly.

[0004] In the aforementioned environment, current methods of drug extraction pose the following risks; 1. Unstable medicine bottles: During the voyage, the ship will be constantly shaking and tilting. The medicine bottles may slide or tilt due to the turbulence, making it difficult to draw out the medicine or causing the liquid to splash out.

[0005] 2. Risk of needle stick injury: Medical staff may lose control of the needle during the medication extraction process due to the turbulence inside the ship, resulting in the risk of needle stick injury, especially in a chaotic situation.

[0006] 3. Inefficient operation: In a bumpy environment, medical staff need to constantly adjust the angle of the medicine bottle and syringe, which increases the time and effort required to extract the medicine.

[0007] 4. Difficulty in achieving accurate liquid aspiration: Especially under extreme turbulence, it is difficult to keep the needle and vial aligned, which can easily lead to failure or over-absorption of the liquid.

[0008] Existing drug extraction devices may have scattered components, cumbersome operation, low emergency efficiency, and insufficient portability and storage, making them unsuitable for medics to carry and quickly access in confined spaces (such as ship cabins).

[0009] Therefore, it is necessary to invent a portable liquid extraction device to solve the above problems. Summary of the Invention

[0010] The purpose of this invention is to provide a portable liquid medicine extraction device for use in confined spaces such as ships, where conditions are limited and unstable. The extraction device is miniaturized and integrated, ensuring portability while adapting to the openings of different types of medicine bottles. Furthermore, it allows for the extraction of medicine by inserting a needle into the bottle even under vibration.

[0011] To achieve this objective, the present invention adopts the following technical solution: A portable liquid medicine extraction device is provided, including a clamping part, one end of which is used to clamp a syringe; The flipping part includes a rotating shaft, which can rotate relative to the clamping part around the rotating shaft. A ratchet tooth is provided on the top side of the flipping part near the rotating shaft, and a locking part that can abut against the ratchet tooth is slidably provided at the bottom end of the clamping part.

[0015] As a preferred embodiment of a portable liquid medicine extraction device, the lower half of the fixing plate is provided with a lower fixing post, which is located diagonally opposite the upper positioning post. When the flipping part rotates, the lower fixing post can abut against the neck of the medicine bottle.

[0016] As a preferred embodiment of a portable liquid dispensing device, the separation assembly further includes a toothed belt. Multiple locking blocks are evenly spaced at the bottom of the inner side of the flipping end. These locking blocks are inclined inwards, and their end faces can abut against the neck of the medicine bottle. The toothed belt is fixedly installed on one side of the flipping end.

A guide post for preventing the toothed belt from being in a vertical position is provided on one side of the guide groove. An opening groove for fitting vials is provided on one side of the bottom of the medicine fixing part.

[0017] As a preferred embodiment of a portable liquid medicine extraction device, the synchronous gear is connected to a transmission gear via a connecting rod. A synchronous rack is provided on one side of the transmission gear, which can mesh with it. A lifting rod is connected to the top of the synchronous rack, which can drive the synchronous rack to slide longitudinally. An upper slot and a lower limiting hole are respectively opened on one side of the lifting rod. A locking post is provided on one side of the lifting rod, which can engage with the upper slot and the lower limiting hole. The locking post is connected to a pressing post that can extend to the outside of the medicine fixing part via a connecting plate. A return spring is provided on one side of the connecting plate, which can synchronously push out the locking post and the pressing post. A compression spring is provided on one side of the synchronous rack for driving it to slide downward.

[0018] As a preferred embodiment of a portable liquid drug extraction device, one end of the clamping part is provided with a slot, and multiple guide rods are arranged in the slot. The drug extraction part includes a positioning slider, which slides longitudinally along the guide rods. One end of the positioning slider is connected to a synchronization frame, and the top end of the synchronization frame is connected to a rod fixing block for mounting a syringe pull rod. The bottom end of the positioning slider is provided with multiple return springs sleeved on the outside of the guide rods, and the return springs are used to apply an upward driving force to the positioning slider.

[0019] As a preferred embodiment of a portable liquid dispensing device, the positioning slider is provided with outwardly retractable ejector blocks on both sides, and an ejector spring is provided on the inner side of the ejector block.

[0020] As a preferred embodiment of a portable liquid extraction device, the locking part is located at the bottom end of the clamping part, and includes a limiting block that can slide longitudinally. The bottom end of the limiting block is provided with a locking tooth that can engage with a ratchet tooth. The top end of the limiting block is provided with a return spring for applying downward pressure. One side of the limiting block is provided with a positioning plate that can fit against the end face of the clamping part, and one end of the limiting block extends to the outside through the positioning plate.

[0021] The beneficial effects of this invention are as follows: The device isolates the operator from direct contact with the vial and needle tip through a mechanical structure. The coordinated design of the bottle-breaking part and the separation component allows the operation of breaking the ampoule head to be completed entirely by mechanical levers, eliminating the need for the operator to break the bottle by hand and avoiding glass cuts. The separation component can be fitted onto the neck of the ampoule to collect any broken bottle head, preventing it from splashing or falling and breaking. The baffle can intercept the rebounding separation component, and the toothed belt is also used to tighten the flipping end and prevent it from shaking. These designs effectively prevent broken bottle heads or the separation component from interfering with or colliding with the needle, greatly reducing the risk of "pricks" caused by loss of hand control in bumpy environments.

[0022] The device simplifies the complex drug extraction process into a few consecutive mechanical actions: clamping the syringe, inserting the vial, flipping and breaking off the vial head, resetting, and pressing to extract the drug. The extraction unit utilizes a return spring for rapid, automatic aspiration; the release mechanism of the separation component allows for quick disposal of the vial head. This integrated, semi-automated operation significantly reduces repeated adjustments required in emergency situations due to environmental disturbances, improving operational speed and success rate, and addressing the pain point of "inefficient operation."

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0050] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0051] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] Example 1; Reference Figures 22 to 23 , Includes a clamping part 1, one end of which is used to clamp the syringe 4; The flipping part 3 includes a rotating shaft 301. The flipping part 3 can rotate around the rotating shaft 301 relative to the clamping part 1. A ratchet tooth 302 is provided on the top of the flipping part 3 near the rotating shaft 301. A locking part 7 that can abut against the ratchet tooth 302 is slidably provided at the bottom of the clamping part 1. The medicine fixing part 5 has a groove at its top for placing the medicine bottle 6, and a positioning block 502 that can engage with the flipping part 3 on one side. The drug extraction part 2 is slidably connected to the clamping part 1. The drug extraction part 2 includes a pull rod fixing block 104 for pulling the pull rod of the syringe 4. Separation component 8, which is detachably installed on the top of the medicine fixing part 5 and sleeved on the outside of the medicine bottle 6, includes a flip end 801 and an insertion end 804, and the contact surface of the flip end 801 and the insertion end 804 is located at the neck of the medicine bottle 6. Bottle-breaking part 9, which is detachably installed on one side of clamping part 1, and is provided with an upper limit post 902 that can abut against medicine bottle 6 or separation component 8; When the flipping part 3 and the clamping part 1 are on the same axis, the needle tip of the syringe 4 is aligned with the mouth of the medicine bottle 6; when the bottom end of the medicine fixing part 5 slides to be flush with the flipping part 3, the needle tip extends to the inside of the medicine bottle 6. The separation component 8 is a disposable and replaceable component, mainly used to collect broken bottle heads to prevent them from falling to the ground and shattering during shaking, thus avoiding accidental injury to personnel.

[0053] The flipping part 3 has a longitudinal groove 304, and a guide rod 305 is provided inside the longitudinal groove 304. A guide slider 504 is provided on one side of the medicine fixing part 5. The medicine fixing part 5 slides longitudinally along the guide rod 305 via the guide slider 504. A return spring 306 for applying downward pressure to the guide slider 504 is sleeved on the outside of the guide rod 305. A slot 307 is provided at the bottom end of the flipping part 3. A positioning block 502 that can engage with the slot 307 is provided at the bottom end of the medicine fixing part 5. A guide slope 503 is provided at one end of the positioning block 502. A button 308 is slidably provided inside the slot 307. A pressing slope 309 that can squeeze the guide slope 503 to disengage it from the engaging state is provided at the end of the button 308. A return spring 310 is sleeved on the outside of the button 308. By controlling the relative sliding between the medicine fixing part 5 and the flipping part 3, the needle tip can be inserted into the interior of the medicine bottle 6, and the ampoule head can be inserted into the bottle breaking part 9. The setting of the rear button 308 can reduce the difficulty of state switching. The overall structure has a high degree of integration and is easy to carry.

[0054] A limiting block 303 is provided on one side of the top of the flipping part 3, which can abut against the clamping part 1. The bottle-breaking part 9 includes a fixing plate 906 detachably installed on one side of the clamping part 1. The inner side of the fixing plate 906 is provided with a slot for the rotating shaft 301 to rotate. The upper limit post 902 is located at the upper half of the fixing plate 906 and is located on the side away from the limiting block 303. When the limiting block 303 abuts against the clamping part 1, the flipping part 3 and the clamping part 1 are on the same axis. When the flipping part 3 rotates along the rotating shaft 301, the upper limit post 902 can abut against the bottle head of the medicine bottle 6 or the flipping end 801 of the separation component 8.

[0055] The lower half of the fixed plate 906 is provided with a transverse sliding groove 901. A pressing shaft 904 is slidably arranged inside the transverse sliding groove 901. A stop post 903 is provided on one side of the pressing shaft 904 located inside the transverse sliding groove 901, which can abut against the flip end 801. The stop post 903 is used to intercept the flip end 801 in the rebound state.

[0056] After the ampoule is broken, the separation component 8 fitted on the neck and the bottle head inside will spring back towards the inside of the device and closer to the fixing plate 906 due to inertia.

[0057] At this time, moving the pressing shaft 904 will cause the stop post 903 in the transverse groove 901 to intercept the rebounding flip end 801 of the separation component 8, blocking it and preventing it from swinging freely. This avoids interference from the flip end 801 on the needle tip of the syringe 4.

[0058] After the liquid is drawn, the operator can then pull the pressing shaft 904 to remove the stop 903, and then safely remove the separation component 8 containing the broken bottle head for disposal.

[0059] This embodiment includes a pressing shaft 904 and a stop post 903, designed for the structure that needs to accommodate broken bottle heads.

[0060] Example 2; Reference Figures 16 to 21 The flipping part 3 has a limiting block 303 on one side of its top end that can abut against the clamping part 1. The bottle-breaking part 9 includes a fixing plate 906 that is detachably installed on one side of the clamping part 1. The inner side of the fixing plate 906 has a slot for the rotating shaft 301 to rotate. The upper limit post 902 is located at the upper half of the fixing plate 906 and is located on the side away from the limiting block 303. When the limiting block 303 abuts against the clamping part 1, the flipping part 3 and the clamping part 1 are on the same axis. When the flipping part 3 rotates along the rotating shaft 301, the upper limit post 902 can abut against the bottle head of the medicine bottle 6 or the flipping end 801 of the separation component 8.

[0061] The lower half of the fixing plate 906 is provided with a lower fixing post 905, which is located diagonally opposite the upper limit post 902. When the flipping part 3 rotates, the lower fixing post 905 can abut against the neck of the medicine bottle 6.

[0062] This solution is suitable when there is no need to store the broken bottle head, such as... Figure 16As shown, the flipping part 3 is in the flipped state at this time, causing the medicine fixing part 5 to engage with the flipping part 3. The ampoule head extends to the side where the fixing plate 906 is located. When the flipping part 3 is rotated, the upper limit post 902 and the lower fixing post 905 form a pair of stable force couple fulcrums. Continuing to turn the flipping part 3, relative movement occurs between the ampoule body being fixed by the medicine fixing part 5 and the ampoule head being locked by the upper limit post 902, thereby using the lever principle to break off the ampoule head. After removing the ampoule head, it is reset to its original position. Figure 19 The process involves separating the drug fixing part 5 from the flipping part 3, rotating the flipping part 3 to a coaxial position with the clamping part 1, and then engaging the drug fixing part 5 with the flipping part 3 to extract the drug. Example

[0063] refer to Figures 1 to 15 This invention provides a portable liquid medicine extraction device. The separation component 8 further includes a toothed belt 802. Multiple locking blocks 803 are evenly spaced at the bottom of the inner side of the flip end 801. The locking blocks 803 are inclined inwards, and their end faces can abut against the neck of the medicine bottle 6. The toothed belt 802 is fixedly installed on one side of the flip end 801. The inner side of the medicine fixing part 5 is provided with a transmission groove 506 and a storage groove 505. The inner side of the transmission groove 506... A synchronous gear 507 capable of meshing with the toothed belt 802 is rotatably mounted. A storage groove 505 for accommodating excess toothed belt 802 is provided below the transmission groove 506. A guide groove 518 for inserting the toothed belt 802 is provided at the top of the medicine fixing part 5. A guide post 508 for preventing the toothed belt 802 from being in a vertical position is provided on one side of the guide groove 518. An opening groove 501 for fitting vials is provided on one side of the bottom end of the medicine fixing part 5.

[0064] The toothed belt 802 is also used to overcome the springback of the flip end 801. By pressing down the synchronous rack 510, the synchronous gear 507 is driven to rotate, and the toothed belt 802 is rotated to retract into the storage groove 505, so that the flip end 801 is in the open and closed state, avoiding springback and affecting the syringe 4 to extract the medicine.

[0065] The synchronous gear 507 is connected to the transmission gear 509 via a connecting rod. A synchronous rack 510 is provided on one side of the transmission gear 509, which can mesh with it. A lifting rod 517 is connected to the top of the synchronous rack 510. The lifting rod 517 can drive the synchronous rack 510 to slide longitudinally. An upper slot 515 and a lower limit hole 516 are respectively opened on one side of the lifting rod 517. A locking post 514 is provided on one side of the lifting rod 517, which can engage with the upper slot 515 and the lower limit hole 516. The locking post 514 is connected to a pressing post 512 that can extend to the outside of the medicine fixing part 5 via a connecting plate. A return spring 513 is provided on one side of the connecting plate, which can simultaneously push out the locking post 514 and the pressing post 512. A compression spring 511 is provided on one side of the synchronous rack 510 for driving it to slide downward.

[0066] The press-type trigger structure enables a rapid response. If a suitable compression spring 511 is used, the instantaneous pulling force of the transmission gear 509 on the toothed belt 802 can break the bottle head from the neck, thus meeting the need for quick dispensing of medicine.

[0067] One end of the clamping part 1 has a slot, and multiple guide rods 202 are arranged in the slot. The drug extraction part 2 includes a positioning slider 204, which slides longitudinally along the guide rods 202. One end of the positioning slider 204 is connected to a synchronization frame 201, and the top end of the synchronization frame 201 is connected to a pull rod fixing block 104 for mounting the syringe 4 pull rod. The bottom end of the positioning slider 204 is provided with multiple return springs 203 sleeved on the outside of the guide rods 202. The return springs 203 are used to apply an upward driving force to the positioning slider 204. By pressing, the return springs 203 can lift the positioning slider 204, thereby driving the pull rod away from the syringe 4, realizing rapid drug extraction.

[0068] The positioning slider 204 has outwardly retractable ejector blocks 206 on both sides. An ejector spring 205 is provided on the inner side of the ejector block 206. The clamping part 1 has positioning grooves 106 on both sides. The ejector block 206 can engage with the positioning groove 106. A pressing block 102 is provided on one side of the positioning groove 106. A trigger protrusion 103 extending into the inner side of the positioning groove 106 is provided on one side of the pressing block 102. The clamping part 1 has clamping arms 101 for clamping the syringe 4 on both sides. A limiting groove 105 for limiting the longitudinal sliding of the syringe 4 is provided at the upper half of the clamping part 1. When the trigger protrusion 103 is pressed on both sides at the same time, the pressing block 102 falls out of the engagement state with the positioning groove 106. Multiple press-triggered mechanical structures reduce the difficulty of operation, thereby reducing the difficulty of drug extraction in a shaking environment, avoiding the process of aligning the needle tip with the drug port, and preventing punctures or misalignments in a shaking environment.

[0069] The locking part 7 is located at the bottom end of the clamping part 1. It includes a limiting block 702 that can slide longitudinally. The bottom end of the limiting block 702 is provided with a locking tooth 704 that can engage with the ratchet tooth 302. The top end of the limiting block 702 is provided with a return spring 703 for applying downward pressure. One side of the limiting block 702 is provided with a positioning plate 701 that can fit against the end face of the clamping part 1. One end of the limiting block 702 extends to the outside through the positioning plate 701. The combination design of the ratchet tooth 302 and the locking tooth 704 avoids the clamping part 1 and the flipping part 3 from shaking after coaxiality. At the same time, it can quickly change from a relatively vertical state to a collinear state, reducing the difficulty of use.

[0070] This invention isolates the operator from direct contact with the ampoule and needle tip through a mechanical structure. The coordinated design of the bottle-breaking part 9 and the separation component 8 allows the operation of breaking the ampoule head to be completed entirely by mechanical levers, eliminating the need for the operator to break the bottle by hand and avoiding glass cuts. The separation component 8 can be fitted onto the neck of the ampoule to collect any broken bottle head, preventing it from splashing or falling and breaking. The baffle 903 intercepts the rebounding separation component 8, and the toothed belt 802 also tightens the flipping end 801 and prevents it from shaking. These designs effectively prevent broken bottle heads or the separation component 8 from interfering with or colliding with the needle, greatly reducing the risk of "pricks" due to loss of hand control in bumpy environments.

[0071] The device simplifies the complex drug extraction process into several consecutive mechanical actions: clamping the syringe 4, inserting the vial, flipping and breaking off the vial head, resetting, and pressing to extract the drug. The drug extraction unit 2 utilizes a return spring 203 to achieve rapid and automatic extraction; the press-release structure of the separation component 8 allows for quick disposal of the vial head. This integrated, semi-automated operation significantly reduces repeated adjustments due to environmental disturbances in emergency situations, improving operational speed and success rate, and solving the pain point of "inefficient operation."

However, such variations, as long as they do not depart from the spirit of the present invention, should be within the protection scope of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
