Description

Technical Field

[0001] The utility model relates to the technical field of medicine dispensing instruments, in particular to an anesthetic medicine dispensing device. Background Art

[0002] The Department of Anesthesiology needs to use various drugs during surgery to ensure the safety and comfort of the patient. During the actual treatment process, the doctor will prepare the drugs according to the patient's condition so that the drugs can achieve the best effect. In the process of preparing anesthetics, sterile syringes are needed to extract the drugs from the bottles.

[0003] At present, in the process of preparing drugs with existing sterile syringes, doctors will hold the medicine bottle with one hand and use the other hand to operate the syringe to complete the operation of extracting drugs. When extracting the liquid medicine with one hand, when the piston rod is pulled to the end of the syringe, it will fall out if not paid attention to. This not only causes waste of liquid medicine, but also pollutes the working environment of the department. Therefore, we propose an anesthesia dispensing device to solve the above problems.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4The top of the syringe 1 is connected with a connecting ring 2, and the connecting ring 2 and the syringe 1 are both provided with a piston rod 3, the piston rod 3 is composed of a piston shaft and a piston, and the working principle of the piston rod 3 and the syringe 1 is the prior art, which will not be described in detail here. The top of the piston rod 3 is connected with a linkage rod 4, and the bottom end of the linkage rod 4 is connected with a limiting block 5. A groove is provided in the connecting ring 2 at a position matching with the linkage rod 4, and the diameter of the groove is smaller than the limiting block 5. Since the diameter of the groove is smaller than the limiting block 5, the limiting block 5 can be effectively prevented from being withdrawn from the groove, so as to limit the piston rod 3, thereby effectively preventing it from being completely withdrawn from the inside of the syringe 1. A limiting ring 6 is provided on the outside of the syringe 1, and an arc block 7 is connected to the upper side of the limiting ring 6. A limiting mechanism is provided inside the arc block 7. When in use, the limiting ring 6 and the arc block 7 cooperate with each other. , to achieve the blocking operation of the limit block 5, so as to achieve the quantitative extraction of the liquid medicine, the limit mechanism includes an insertion rod 8, the insertion rod 8 is inserted at the center position of the arc block 7, one end of the insertion rod 8 is connected to a pull block 9, the other end of the insertion rod 8 passes through the inner wall of the arc block 7 and extends in the syringe 1, and the side wall of the syringe 1 is equidistantly distributed with the position corresponding to the insertion rod 8. When in use, the position of the limit ring 6 can be quickly adjusted by the cooperation of the pull block 9 and the limit groove, so as to effectively improve the convenience of the device when in use. A guide groove 13 is provided inside the limit ring 6, and the inner wall of the guide groove 13 is abutted against the outer wall of the linkage rod 4. When in use, the limit ring 6 can be limited by the groove hole provided inside the limit ring 6, so as to effectively prevent the limit ring 6 from rotating during the up and down movement, so that the position of the insertion rod 8 always corresponds to the position of each group of limit grooves.

[0020] Further, see Figure 1 It can be known that a buffer plate 14 is connected to the upper side of the limit block 5, and the buffer plate 14 is set to a rubber material. When in use, the buffer plate 14 set by the rubber material can effectively reduce the impact force between the limit block 5 and the limit ring 6 to achieve a protective operation on the limit block 5.

[0021] Further, see Figure 3 and Figure 4 It can be known that a connecting block 11 is connected to the lower side of the pull block 9, and a connecting spring 12 is laterally connected to the side of the connecting block 11, and the other end of the connecting spring 12 is fixedly connected to the arc block 7. When in use, the connection spring 12 is arranged to ensure that the insertion rod 8 is reliably engaged in the syringe 1.

[0022] Further, see Figure 3 and Figure 4It can be known that a guide rod 10 is inserted into the interior of the connecting spring 12, and the guide rod 10 is arranged as an L-shaped structure. The side of the guide rod 10 is fixedly connected to the arc block 7, and a hole adapted to the guide rod 10 is opened inside the connecting block 11. Through the L-shaped guide rod 10, the insertion rod 8 can be guided to effectively prevent the connecting spring 12 from tilting when subjected to force, thereby realizing the protection of the connecting spring 12.

[0023] Working principle: When the utility model is used, the doctor can first pull the pull block 9 horizontally according to the amount of medicine to be extracted, thereby driving the insertion rod 8 to slide inside the arc block 7 and be drawn out from the inner wall of the syringe 1 to release the limit ring 6. Then the doctor can slide the limit ring 6 up and down to the appropriate scale mark on the outer surface of the syringe 1. After sliding to the appropriate position, the doctor can stop pulling the pull block 9, so that the insertion rod 8 is reset by the elastic force of the connecting spring 12 and is engaged with the corresponding limit ring opened on the side wall of the syringe 1. The doctor can then open the plastic cover on the medicine bottle, and then insert the needle connected to the bottom end of the syringe 1 into the plastic of the medicine bottle, and then manually pull the piston rod 3 to draw the medicine in the medicine bottle into the interior of the syringe 1. When the limit block 5 and the limit ring 6 are in contact, the quantitative extraction of the medicine is completed. Then the doctor can pull the needle out of the medicine bottle and inject the medicine into the dispensing bottle to prepare the medicine. The above is the entire working principle of the utility model.
