[0035] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Embodiment 1:

[0037] This embodiment provides a height-adjustable nursing medication device. Figure 1 The nursing dispensing device includes a vial 1, a solvent bag 2, and an infusion tube 3 with puncture needles 4 at both ends, wherein the puncture needle 4 at the first end punctures the solvent bag 2, and a peristaltic pump 5 is provided on the infusion tube 3 to drive the internal liquid medicine to flow, and the puncture needle 4 at the second end is movable and used to puncture the vial 1. Under the action of the peristaltic pump, the liquid medicine in the vial 1 can be transported to the solvent bag 1 and mixed with the liquid medicine in the solvent bag 1, thereby realizing the configuration of the liquid medicine.

[0038] It is worth mentioning that, in order to adapt to the movement of the puncture needle 4 at the second end, the infusion tube 3 is a soft tube.

[0039] In order to adapt to the current configuration of multiple liquid medicines, it is often necessary to perform puncture work on multiple vials 1 in turn. Based on this, in this embodiment, the number of vials 1 is several, such as Figure 1 The number of the cillin bottles 1 shown is 2, and may be other numbers, and the specific position is located above the puncture needle 4 at the second end, and also includes:

[0040] The translation mechanism 6 is connected to the vial 1 to drive the vial 1 to move in a horizontal direction.

[0041] Please refer to Figure 2 The translation mechanism 6 includes a first guide rail 61 arranged horizontally, a first slider 62 slidably matched with the first guide rail 61 , and a first clamp 63 fixedly connected to the first slider 62 for clamping the vial 1 .

[0042] It is worth mentioning that the number of the first sliders 62 corresponds to the number of the vials 1 and the number of the first clamps 63. Alternatively, there is only one first slider 62, and all the clamps 63 are mounted on the only first slider 62.

[0043] The first slider 62 moves along the first guide rail 61 , thereby achieving the position switching of the vial 1 in the horizontal direction.

[0044] The height adjustment mechanism 7 is connected to the puncture needle 4 at the second end to drive the puncture needle 4 at the second end to move toward / away from one of the plurality of vials 1 along the height direction.

[0045] Please refer to Figure 3 The height adjustment mechanism 7 includes a second vertically arranged guide rail 71, a second slider 72 slidably matched with the second guide rail 71, and a second clamp 73 fixedly connected to the second slider 72 for clamping the puncture needle 4 at the second end.

[0046] The second slide block 72 moves along the second guide rail 71, thereby achieving the movement of the puncture needle 4 in the height direction. Figure 4 As shown, when the second slider 72 moves upward, the puncture needle 4 punctures the vial 1; conversely, when the second slider 72 moves downward, the puncture needle 4 is separated from the vial 1.

[0047] It is worth mentioning that Figure 3 As shown, in order to prevent the vial 1 from hitting the second guide rail 71 or the second slider 72, the second clamp 73 extends upward from the second slider 72, and the top clamps the puncture needle 4 at the second end.

[0048] Please refer to Figure 1 In order to fix the solvent bag 2 , the present embodiment further comprises a bracket 8 , and a hook 81 for hanging the solvent bag 2 is disposed on the top of the bracket 8 .

[0049] This embodiment realizes the position change of multiple syringe bottles through the translation mechanism, and combines with the height adjustment mechanism to drive the puncture needle to move toward / away from one of the syringe bottles, thereby realizing the switching of the puncture needle between multiple syringe bottles to meet the needs of medical staff for the mixed preparation of multiple drug solutions.

[0050] Embodiment 2:

[0051] When the puncture needle 4 punctures the vial 1, the tail of the puncture needle 4 will be exposed to the air. In order to prevent this from happening and to prevent the puncture needle 4 from being contaminated, the second embodiment improves the puncture needle 4. The details are as follows:

[0052] like Figure 5 and Figure 6 As shown, the puncture needle 4 includes a fixedly connected pointed portion 41 for puncture and a connecting portion 42 for connecting to the end of the infusion tube 3. The pointed portion 41 and the connecting portion 42 are hollow inside to form a cavity 43. The cavity 43 forms an opening 44 at the end of the connecting portion 42. The side wall of the pointed portion 41 is provided with a groove 45 for the circulation of the drug solution.

[0053] like Figure 4 As shown, when the puncture needle 4 punctures the vial 1, the drug solution flows from the slot 45 into the cavity 43 and flows into the infusion tube 3 through the opening 44, thereby realizing the transfer of the drug solution.

[0054] The outer wall where the pointed portion 41 and the connecting portion 42 meet is provided with a baffle 46 perpendicular to the axial direction. When the puncture needle 4 punctures the vial 1, the baffle 46 abuts against the rubber stopper 11 of the vial 1 / solvent bag 2 to form a barrier, thereby preventing the tail of the puncture needle 4 from being exposed to the outside.

[0055] At the same time, in order to further enhance the sealing performance of the connection between the puncture needle 4 and the rubber stopper 11, a step 47 is provided on the outer wall of the pointed portion 41, and a gap 48 is formed between the bottom of the step 47 and the baffle 46 for accommodating the rubber stopper 11 of the vial 1 / solvent bag 2. When the baffle 46 abuts against the rubber stopper 11 of the vial 1 / solvent bag 2, the rubber stopper 11 is inserted into the gap 48 to prevent leakage of the liquid medicine. It is worth mentioning that the slot 45 extends from the bottom of the step 47 toward the tip side of the pointed portion 41.

[0056] At the same time, in order to prevent the puncture needle 4 from being able to penetrate smoothly, the top of the step 47 includes a curved surface 49 that transitions to the outer wall of the pointed portion 41 .

[0057] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
