Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a locking and ejecting mechanism of a medical infusion pump workstation. Background Art

[0002] Infusion pumps can accurately control the flow rate and volume of infusion. When a variety of drug infusions are required, multiple infusion pumps need to be used centrally, so a medical infusion pump workstation is needed to manage the pump body in a fixed manner.

[0003] In the prior art, there is an infusion workstation and a medical pump with a publication number of CN206252699U, which includes a rotating shaft, a force-applying member, a pump positioning member and a transmission mechanism. The pump positioning member has a protrusion for positioning the pump, and the protrusion is arranged in a manner that can rotate around the radial direction of the rotating shaft; on the rotation path of the protrusion, there is a first position where the protrusion can limit the pump and a second position where the protrusion can release the limit. The transmission mechanism is connected to the rotating shaft and the pump positioning member, and converts the rotational motion of the rotating shaft into the rotational motion of the protrusion. During use, after placing the pump on the workstation, the user can drive the rotating shaft to rotate through the force-applying member, thereby driving the protrusion to move from the second position to the first position, so that the protrusion forms a match with the pump, and then locks the pump on the infusion workstation. However, when it is used, when the limit on the pump body is released, the pump body cannot be moved away from the limiter, so that medical staff need to use the adjustment of the rotating shaft to prevent it from rotating and resetting and limiting the pump body again, which has certain use defects. Utility Model Content

[0004] The purpose of the utility model is to provide a locking and ejecting mechanism for a medical infusion pump workstation to solve the problem raised by the above background technology that the infusion pump workstations currently on the market are inconvenient to stably lock the pump body and eject it with one button, resulting in cumbersome operation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a locking and ejection mechanism of a medical infusion pump workstation, comprising an infusion pump and a support plate, wherein the infusion pump is provided with two groups, and the infusion pump is slidably connected to the outer side of the support plate, a top head is provided through the front side of the support plate, and a top head limit block is provided on the back side of the support plate, and the support plate and the top head limit block are fixedly connected by screws, and a top head compression spring is connected between the top head limit block and the back side of the support plate, and two groups of hexagonal shaft limit blocks A and hexagonal shaft limit blocks B are symmetrically fixedly installed on the back side of the support plate, and an ejection knob assembly is installed between the hexagonal shaft limit block A and the hexagonal shaft limit block B, and four groups of locking assemblies are installed on the support plate to realize the positioning of the infusion pump.

[0006] Preferably, the lock assembly includes a lock base fixedly mounted on the back of the support plate, and a lock is rotatably connected to the lock base through a positioning pin A, and a tension spring is connected between the lock and the lock base, and the lock and the positioning groove on the infusion pump are engaged and positioned.

[0007] By adopting the above technical solution, after the infusion pump is pushed in, it can resist and push the lock to rotate elastically. When the locking part of the lock moves to the positioning groove of the infusion pump, the lock will elastically rotate and reset to achieve the positioning of the infusion pump.

[0008] Preferably, the ejection knob assembly includes a hexagonal ejection shaft rotatably installed between a hexagonal shaft limit block A and a hexagonal shaft limit block B in the same group, and one end of the hexagonal ejection shaft passes through the side wall of the support plate, and a knob is fixedly installed on the outer side of one end of the hexagonal ejection shaft extending out of the support plate through a positioning pin B.

[0009] By adopting the above technical solution, the angle of the hexagonal ejection shaft can be conveniently adjusted by rotating the knob, which facilitates the subsequent ejection operation of the infusion pump.

[0010] Preferably, the ejection knob assembly also includes a locking cam fixedly mounted on the outside of the hexagonal ejection shaft by a locating pin B, and the outside of the locking cam abuts against the lock, and the fitting surfaces of the locking cam and the lock are also inclined, and at the same time, the locking cam rotates and abuts to cause the lock to rotate.

[0011] By adopting the above technical solution, when the hexagonal ejection shaft drives the locking cam to rotate, the locking cam can resist and push the lock to rotate elastically, so that the lock releases the positioning of the infusion pump.

[0012] Preferably, an ejector cam is fixedly mounted on the outer side of the hexagonal ejector shaft via a positioning pin B, and the positions of the ejector cam and the ejector limit block are correspondingly arranged.

[0013] By adopting the above technical solution, when the hexagonal ejector shaft rotates, the ejector cam can be driven to rotate synchronously, so that the ejector cam can resist and push the ejector head limit block.

[0014] Preferably, the ram and the ram limiting block form an elastic telescopic structure through a ram compression spring and a support plate, and the ram fixedly connected to the outside of the ram limiting block fits the infusion pump.

[0015] By adopting the above technical solution, when the mandrel limit block is resisted and drives the mandrel to elastically expand and contract, the mandrel can resist and push the infusion pump, so that the infusion pump is out of the locking range of the lock buckle, which is convenient for the subsequent removal of the infusion pump.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the locking and ejecting mechanism of the medical infusion pump workstation can conveniently lock and position the infusion pump, and can be ejected with one key during the disassembly process, which is convenient to operate and reduces the workload of medical staff. The specific contents are as follows:

By pushing the infusion pump along the slide groove on the support plate, the card slot at the end of the infusion pump can contact the lock of the lock assembly, so that the lock is automatically inserted into the card slot under the elastic force of the tension spring, thereby completing the effective locking of the infusion pump;

[0018] 2. A ejector head, a lock assembly and an ejector knob assembly are provided. When the infusion pump needs to be taken out, the knob is rotated to drive the hexagonal ejector shaft to rotate, so that the lock cam contacts and pushes the lock to rotate, so that the lock and the slot on the infusion pump are released from engagement, and then the ejector cam contacts the ejector head limit block, so that the ejector head limit block drives the ejector head to perform elastic telescopic adjustment, thereby pushing the infusion pump, so that the infusion pump is out of the locking range of the lock, and it is convenient to disassemble and remove the infusion pump.

[0032] See also Figure 1-Figure 5 The utility model provides a technical solution: a locking and ejection mechanism of a medical infusion pump workstation, comprising an infusion pump 1 and a support plate 3, wherein the infusion pump 1 is provided with two groups, and the infusion pump 1 is slidably connected to the outer side of the support plate 3, a top head 2 is penetrated on the front side of the support plate 3, and a top head limit block 5 is provided on the back side of the support plate 3, and the support plate 3 and the top head limit block 5 are fixedly connected by screws, and a top head compression spring 4 is connected between the top head limit block 5 and the back side of the support plate 3, and two groups of hexagonal axis limit blocks A6 and hexagonal axis limit blocks B7 are symmetrically fixedly installed on the back side of the support plate 3, and an ejection knob assembly 10 is installed between the hexagonal axis limit block A6 and the hexagonal axis limit block B7, and four groups of locking buckle assemblies 8 are installed on the support plate 3 to realize the positioning of the infusion pump 1.

[0033] The locking assembly 8 includes a locking base 801 fixedly mounted on the back of the support plate 3, and a locking buckle 802 is rotatably connected to the locking base 801 via a positioning pin A803, and a tension spring 9 is connected between the locking buckle 802 and the locking base 801, and the locking buckle 802 and the positioning groove on the infusion pump 1 are engaged and positioned.

[0034] like Figure 1-Figure 4 , Figure 6 and Fig.10As shown, when the infusion pump 1 needs to be installed, the infusion pump 1 is pushed so that the infusion pump 1 slides along the guide rail of the support plate 3. When the infusion pump 1 contacts the lock buckle 802, it will resist the lock buckle 802 to rotate. When the lock buckle 802 moves to the slot position on the infusion pump 1, the lock buckle 802 will automatically rotate and reset under the elastic force of the tension spring 9, thereby being stuck in the slot of the infusion pump 1, thereby achieving rapid and stable locking of the infusion pump 1.

[0035] The ejection knob assembly 10 includes a hexagonal ejection shaft 1005 rotatably installed between the hexagonal shaft limit block A6 and the hexagonal shaft limit block B7 of the same group, and one end of the hexagonal ejection shaft 1005 passes through the side wall of the support plate 3, and the knob 1001 is fixedly installed on the outer side of one end of the hexagonal ejection shaft 1005 extending out of the support plate 3 through a positioning pin B1002.

[0036] The ejection knob assembly 10 also includes a locking cam 1003 fixedly mounted on the outside of the hexagonal ejection shaft 1005 through a positioning pin B1002, and the outside of the locking cam 1003 abuts against the lock 802, and the fitting surfaces of the locking cam 1003 and the lock 802 are also arranged with an inclined surface, and the locking cam 1003 rotates and abuts against each other to cause the lock 802 to rotate. An ejection cam 1004 is fixedly mounted on the outside of the hexagonal ejection shaft 1005 through a positioning pin B1002, and the positions of the ejection cam 1004 and the ejector stop block 5 are arranged correspondingly.

At this time, the locking cam 1003 on the outside of the hexagonal ejection shaft 1005 will resist and push the lock 802 to rotate elastically, so that the lock 802 is disengaged from the slot of the infusion pump 1, thereby releasing the lock of the infusion pump 1. Subsequently, the ejection cam 1004 will resist and push the ejector head limit block 5 during the rotation process, so that it drives the ejector head 2 to elastically expand and contract, so that the ejector head 2 pushes the infusion pump 1 out of the locking range of the lock 802, which is convenient for the subsequent taking of the infusion pump 1 and the operation is convenient.
