[0028] Please refer to Figures 1 to 3 The utility model proposes a medicine dispensing pipette 1000, including a gripping portion 1 and a piercing member 2, wherein the gripping portion 1 has an accommodating cavity 11 formed therein, the piercing member 2 penetrates the gripping portion 1, both ends of the piercing member 2 are piercing ends 21, an air passage 201 penetrating the piercing member 2 is formed therein, and a liquid passage 202 connecting the accommodating cavity 11 and the outside is formed therein.

[0029] In this embodiment, the two puncture ends 21 are respectively inserted into the two medicine bottles. At this time, due to the existence of the accommodating chamber 11, the pressure in the liquid passage 202 will be lower than the pressure in the air passage 201, so that the medicine liquid in the upper medicine bottle will flow into the accommodating chamber 11 through one liquid passage 202, and then flow into the lower medicine bottle through the other liquid passage 202. At the same time, the air in the lower medicine bottle will flow into the upper medicine bottle through the air passage 201, so that the medicine dispensing can be carried out quickly and conveniently, thereby improving the work efficiency.

[0030] Further, in one embodiment of the present invention, please refer to Figure 2 Two liquid passages 202 are formed inside the puncture end 21, so that during the process of medical staff dispensing medicine, the liquid medicine in the upper medicine bottle can flow into the accommodating chamber 11 through the two liquid passages 202 at the same time, and then flow into the lower medicine bottle through the two liquid passages 202, thereby increasing the flow rate of the liquid medicine and accelerating the dispensing speed. The two liquid passages 202 are symmetrically arranged relative to the axial direction of the puncture end 21, so that during the flow of the liquid medicine, it can flow smoothly in the two liquid passages 202 and maintain a stable flow rate.

[0031] Similarly, in one embodiment of the present invention, please refer to Figure 3Two air passages 201 are formed inside the piercing member 2, so that when medical staff prepare medicines, the air in the lower medicine bottle can flow to the upper medicine bottle through the two air passages 201 at the same time, ensuring the flow speed of the gas. In addition, the two air passages 201 are symmetrically arranged relative to the axial direction of the piercing member 2, so that during the process of gas, the air can flow smoothly in the two air passages 201 and maintain a stable flow rate.

[0032] Specifically, in one embodiment of the present invention, please refer to Figure 2 and Figure 3 , two liquid passage channels 202 are formed inside the puncture end 21, and two air passage channels 201 are formed inside the puncture member 2. In this case, when the medicine bottle at the top and the medicine bottle at the bottom exchange liquid and air during medication, the flow rate of the medicine liquid and air can be accelerated. The two air passage channels 201 and the two liquid passage channels 202 are staggered along the circumference of the puncture member 2, that is, along the circumference of the puncture member 2, there are two air passage channels 201 on both sides of any liquid passage channel 202, and there are two liquid passage channels 202 on both sides of any air passage channel 201. In this case, the medicine liquid and the air flow independently and will not interfere with each other, and the stability of the flow rate of the medicine liquid is guaranteed while the flow rate of the medicine liquid is large. In addition, when observed from top to bottom, the line connecting the axes of the two liquid passage channels 202 and the line connecting the axes of the two air passage channels 201 are in a "cross" shape, which can match the tip design of the puncture end 21.

[0033] In order to ensure the stability of the dispensing process, in one embodiment of the present invention, please refer to Figure 2 The axis of the air passage 201 is parallel to the axis of the liquid passage 202, that is, during the flow of the liquid medicine and the air, the flow direction of the liquid medicine is completely opposite to the flow direction of the air, so that the flow of the liquid medicine will not be disturbed by the flow of the air, ensuring the smooth flow of the liquid medicine.

[0034] Furthermore, in one embodiment of the utility model, along the axial direction of the puncture member 2, the height of the air outlet of the air passage 201 is consistent with the height of the liquid inlet of the liquid passage 202 of one of the puncture ends 21, and the height of the air inlet of the air passage 201 is consistent with the height of the liquid outlet of the liquid passage 202 of the other puncture end 21. In this way, when dispensing medicine, the inlet and outlet positions of the liquid medicine are highly consistent with the inlet and outlet positions of the air, so that when the liquid medicine is discharged from the liquid outlet to the medicine bottle below, the air in the medicine bottle below will enter from the air inlet at the same time under the pressure change, and then flow into the medicine bottle above, thus ensuring the stable flow of the liquid medicine.

[0035] Furthermore, in one embodiment of the utility model, the opening size of the liquid inlet, the opening size of the liquid outlet, the opening size of the air outlet and the opening size of the air inlet are consistent in size, so that during the flow of the medicine liquid and the gas, the flow rate per unit time is the same, so that the medicine liquid can flow rapidly while ensuring smooth flow.

[0036] For ease of use, in one embodiment of the present invention, please refer to Figure 1 From the middle of the grip portion 1 to the two ends of the grip portion 1, the cross-sectional area of ​​the grip portion 1 gradually decreases. Specifically, the grip portion 1 is an arched elliptical shape, which can correspond to the curved palm shape, making it convenient for medical staff to hold it with their hands, thereby improving the operating experience of medical staff.

[0037] Further, in one embodiment of the present invention, please refer to Figure 1 The dispensing pipette 1000 also includes two limit members 3, each limit member 3 is sleeved on one end of a puncture end 21 close to the gripping portion 1. After a puncture end 21 penetrates a medicine bottle, as the dispensing pipette 1000 gets closer and closer, the limit member 3 can fit and abut against the mouth of the medicine bottle to limit the position. By setting the limit member 3, it is possible to ensure that the insertion depth of the puncture end 21 is limited, and it is prevented that the puncture end 21 is inserted too deeply, resulting in the liquid medicine in the medicine bottle remaining in the medicine bottle and unable to flow out. At the same time, it also ensures that the contact between the puncture end 21 and the medicine bottle is more stable, reducing the shaking and unstable factors in the dispensing process, and reducing the difficulty of operation. Overall, by setting the limit member 3, the operation time of dispensing can be reduced and the work efficiency of dispensing can be improved.

[0038] Specifically, in one embodiment of the present invention, the grip 1 and the piercing member 2 are integrally formed, which helps ensure stability and ease of operation during use. The integrally formed grip 1 and piercing member 2 can reduce the number of connections between components, reducing the possibility of potential leakage or other problems. This design can also improve the overall strength and durability of the product, ensuring long-term reliable use.

[0039] Furthermore, in one embodiment of the present invention, the grip portion 1 is made of a flexible material, such as rubber, silicone, plastic, etc. The soft grip portion 1 can increase the comfort of gripping and reduce the fatigue of the user's hands. In addition, the soft grip portion 1 also helps to provide better grip and control, making the operation more precise and stable. In general, the selection of a flexible material as the design of the grip portion 1 helps to improve the user experience and the convenience of operation.

[0040] Furthermore, in one embodiment of the present invention, the grip portion 1 is made of a transparent material, such as polyethylene, polypropylene, etc. The grip portion 1 made of a transparent material allows the user to clearly see the flow of the internal liquid medicine, which helps to control and adjust the flow of the liquid medicine. Such a design can improve the accuracy and visibility of the operation, ensuring that the dispensing process is more accurate and smooth. In addition, the transparent grip portion 1 also allows the user to check whether there are bubbles or other abnormal conditions inside at any time, make adjustments in time, and improve the efficiency and stability of the operation.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
