Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a syringe for preparing nebulized drug solutions. Background Technology

[0002] Nebulized inhalation therapy is a core method of drug administration for respiratory diseases. Currently, the syringes used for preparing nebulized inhalation solutions in clinical practice are still those used for intravenous injection. When the same syringe is used for nebulized inhalation and intravenous medication, the nebulized medication prepared in the syringe and the intravenous medication look the same. Medical staff can easily mistake the nebulized medication for the intravenous medication, resulting in medication errors. This phenomenon has occurred in many hospitals, posing a significant medical safety hazard and endangering the health of patients.

[0003] The main factors leading to the aforementioned medical safety hazards are: the homogenization of syringe shapes leads to visual recognition failure, and the consistency of appearance causes cognitive confusion; secondly, the physical compatibility defects of the interface make misconnection feasible. In order to eliminate the aforementioned medical safety hazards, there is an urgent need for a syringe that is different from conventional syringes and is specifically used for the extraction and injection of nebulized drugs. Utility Model Content

[0004] Therefore, this utility model provides a syringe for preparing atomized drug solutions to solve the problem that the homogeneity of syringe shapes in the prior art can easily lead to confusion in the use of different drug solutions.

[0005] To achieve the above objectives, the embodiments of this utility model provide the following technical solutions:

[0006] A syringe for preparing atomized medication includes an injection tube body. One end of the injection tube body is provided with an integrally formed conical needle tube. The conical needle tube has two parallel partitions inside. A turntable is rotatably connected between the two partitions. Each of the two partitions has a first slot. The turntable has a second slot corresponding to the first slot. The first slot and the second slot cooperate to make the interior of the conical needle tube in a communicating state. The outside of the turntable has two symmetrically distributed force-bearing blocks. The conical needle tube has a transverse sliding groove for the two force-bearing blocks to pass through.

[0007] One end of the injection tube is movably fitted with a needle cap for covering the conical needle tube. The needle cap is provided with two engaging components. The two engaging components can deform to engage with the two force blocks. The needle cap can rotate synchronously with the turntable to block the communication state of the conical needle tube.

[0008] As a preferred embodiment of this utility model, both of the transverse sliding grooves are distributed laterally along the outer shape of the conical needle tube, and the length of the transverse sliding groove is greater than the width of the force-bearing block.

[0009] In a preferred embodiment of this utility model, the second slot is located on the turntable away from the center point, and the diameter of the second slot is smaller than the radius of the turntable. A positioning hole is provided at the center of the force-bearing block, and a silicone sleeve is fixedly fitted around the outer periphery of the turntable.

[0010] In a preferred embodiment of this utility model, the first slot is located on the partition away from the center point, and the diameter of the first slot is smaller than the radius of the partition, and the diameters of the first slot and the second slot are the same.

[0011] When the force-bearing block is located at one end of the corresponding transverse sliding groove, the second groove coincides with the two first grooves. When the force-bearing block is located at the other end of the corresponding transverse sliding groove, there is a gap between the second groove and the two first grooves.

[0012] In another embodiment of the present invention, the locking assembly includes a pressure block that always passes through the needle cap. One end of the pressure block located outside the needle cap is provided with a connecting strip that connects to the outside of the needle cap. The other end of the locking assembly near the turntable is provided with a locking pin. The pressure block extends into the needle cap, allowing the locking pin to extend into the positioning hole corresponding to the turntable.

[0013] As a preferred embodiment of this utility model, the outside of the needle cap port is provided with a connecting scale line and a sealing scale line, and the outside of the injection tube body is provided with a positioning line. When the connecting scale line is aligned with the positioning line, the two engaging components can engage with the two force-bearing blocks in the conical needle tube in the connected state. When the sealing scale line is aligned with the positioning line, the two engaging components can engage with the two force-bearing blocks in the conical needle tube in the sealed state.

[0014] The embodiments of this utility model have the following advantages:

[0015] This invention integrates the injection needle and injection tube into a single structure to prevent the mixing of different medications. A rotating structure within the integrated injection tube allows control over the connection status of the injection needle, enabling the injection tube to provide a sealed storage function for the medication. When the medication container is non-reusable and there is remaining medication, it serves as a temporary storage device. The integrated needle in its sealed state, combined with the injection tube body, and the cap that allows switching the connection status of the injection needle, effectively prevents accidental contact by children.

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figures 1 to 4 As shown, this embodiment provides a syringe for preparing atomized drug solution, including an injection tube body 1. One end of the injection tube body 1 is provided with an integrally formed conical needle tube 2. The inside of the conical needle tube 2 is provided with two parallel partitions 3. A turntable 4 is rotatably connected between the two partitions 3. Each of the two partitions 3 is provided with a first groove 301. The turntable 4 is provided with a second groove 401 corresponding to the first groove 301. The first groove 301 and the second groove 401 cooperate to make the inside of the conical needle tube 2 in a communicating state.

[0032] The second slot 401 is located on the turntable 4 away from the center point, and the diameter of the second slot 401 is smaller than the radius of the turntable 4. A positioning hole 4021 is provided at the center of the force block 402, and a silicone sleeve 403 is fixedly sleeved on the outer periphery of the turntable 4.

[0033] The first slot 301 is located on the partition 3 away from the center point, and the diameter of the first slot 301 is smaller than the radius of the partition 3. The diameters of the first slot 301 and the second slot 401 are the same.

[0034] When the force-bearing block 402 is located at one end of the corresponding horizontal sliding groove 201, the second groove 401 coincides with the two first grooves 301. When the force-bearing block 402 is located at the other end of the corresponding horizontal sliding groove 201, there is a gap between the second groove 401 and the two first grooves 301.

[0035] Specifically, in the initial state, the second slot 401 on the turntable 4 inside the conical needle tube 2 coincides with the first slot 301 on the two partitions 3. At this time, the injection tube body 1 performs a suction action, which allows the medicine in the vial to be drawn into the injection tube body 1 through the conical needle tube 2. At the same time, the medicine stored in the injection tube body 1 can also be discharged through the conical needle tube 2.

[0036] Furthermore, in this embodiment, both the first slot 301 and the second slot 401 are located away from the center of the partition 3 and the turntable 4. When the turntable 4 is rotated, the second slot 401 will gradually reduce the overlapping area with the two first slots 301 until the second slot 401 does not overlap with the two first slots 301 at all. At this time, the injection tube body 1 is in a sealed state. The piston inside the injection tube body 1 can neither be pushed in nor pulled out. This is used for situations where there is still a residual amount of the aspirated liquid that needs to be maintained after use.

[0037] For example, the injection tube body 1 is a conventional 10ml injection tube structure, which has a sliding rubber piston and push rod inside, and a scale line corresponding to the volume on its outside.

[0038] The turntable 4 has two symmetrically distributed force-bearing blocks 402 on its exterior, and the conical needle tube 2 has a transverse sliding groove 201 through which the two force-bearing blocks 402 pass.

[0039] One end of the injection tube body 1 is movably fitted with a needle cap 5 for covering the conical needle tube 2. The needle cap 5 is provided with two locking components 6. The two locking components 6 can deform to engage with two force blocks 402. The needle cap 5 can rotate synchronously with the turntable 4 to block the connection state of the conical needle tube 2.

[0040] Both transverse sliding grooves 201 are distributed laterally along the outer shape of the conical needle tube 2, and the length of the transverse sliding grooves 201 is greater than the width of the force-bearing block 402.

[0041] Specifically, the design of the force-bearing block 402 sliding within the transverse sliding groove 201 ensures that when the force-bearing block 402 slides to one end of the transverse sliding groove 201, the second slot 401 on the turntable 4 is completely overlapped with the two first slots 301. When the force-bearing block 402 slides to the other end of the transverse sliding groove 201, the overlapping area of ​​the second slot 401 on the turntable 4 gradually decreases until the force-bearing block 402 is located at the other end of the transverse sliding groove 201. At this point, the second slot 401 is completely non-overlapping with the two first slots 301, thus blocking the conical needle tube 2 and preventing it from connecting.

[0042] The locking assembly 6 includes a pressure block 601 that always passes through the needle cap 5. One end of the pressure block 601 located outside the needle cap 5 is provided with a connecting strip 602 that connects to the outside of the needle cap 5. The other end of the locking assembly 6 near the turntable 4 is provided with a locking pin 603. The pressure block 601 extends into the needle cap 5 so that the locking pin 603 can extend into the positioning hole 4021 of the corresponding turntable 4.

[0043] The outside of the syringe cap 5 is provided with a scale line 501 and a sealing scale line 502. The outside of the injection tube body 1 is provided with a positioning line 101. When the scale line 501 and the positioning line 101 are aligned, the two engaging components 6 can engage with the two force blocks 402 in the conical syringe 2 in the connected state. When the sealing scale line 502 and the positioning line 101 are aligned, the two engaging components 6 can engage with the two force blocks 402 in the conical syringe 2 in the sealed state.

[0044] Specifically, the syringe cap 5 is used to protect the syringe from contamination when the device is stored. To prevent the liquid medicine stored in the syringe body 1 from leaking out due to accidental contact by a child when the device is stored, the rotating turntable 4 is implemented by two locking components 6 installed on the syringe cap 5.

[0045] With the syringe cap 5 on, if the conical syringe 2 is in a connected state, first rotate the syringe cap 5 until the connecting scale line 501 is aligned with the positioning line 101 on the injection tube body 1. Then press down the pressure blocks 601 of the two locking components 6, so that as the two pressure blocks 601 are inserted into the syringe cap 5, the two locking pins 603 respectively engage with the positioning holes 4021 on the corresponding two force blocks 402. Then rotate the injection tube body 1 until the positioning line 101 is aligned with the sealing scale line 502. At this time, the turntable 4 rotates to seal the conical syringe 2. Releasing the pressure block 601 will allow the connecting strip 602 to provide the spring force to reset the pressure block 601.

[0046] If the conical needle tube 2 is blocked at this time, first rotate the needle cap 5 until the blocking scale line 502 is aligned with the positioning line 101 on the injection tube body 1, then press the two pressure blocks 601 to engage the two force blocks 402 and rotate the injection tube body 1, so that the turntable 4 can rotate to the state where the conical needle tube 2 is no longer blocked.

[0047] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
