Description

Technical Field

[0001] The utility model belongs to the field of medical appliances, and in particular relates to a rolling injection storage and access device. Background Art

[0002] In order to meet the actual clinical needs, some emergency drugs and spare drugs are stored in various departments or units of medical institutions, most of which are injections. For the convenience of management, inventory and use, these injections are generally placed on the injection tray of the original packaging of the drug and then placed in the emergency vehicle or the spare drug counter. Because the frequency of using emergency drugs and spare drugs in each department or unit of the medical institution varies, it is common for drugs to become invalid or close to their expiration date in many areas where emergency rescue does not often occur. Therefore, medical institutions have formulated a "left-in-right-out, first-in-first-out" drug retrieval specification, that is, drugs are taken from the right side of the medicine box first, and then the vacant positions on the right are filled by the drugs on the left, forming a "left-in-right-out" circular use state as a whole, and usually "left-in-right-out" is prominently marked on the injection box or medicine box, so that drugs closer to the expiration date can be used first.

[0003] After medical staff use one or several injections, they need to apply for corresponding drugs from the pharmacy in time to replenish them in order to maintain a fixed base of emergency drugs and spare drugs. The replenished drugs are often inconsistent with the expiration dates of the previously stored drugs, so when replenishing, medical staff need to take out the drugs that are closer to the expiration date one by one and place them on the right, and place the newly replenished drugs on the left to ensure the safety of the drug expiration date. However, this method has certain defects: on the one hand, it increases the workload of medical staff, and they are often unable to truly implement "left in, right out, first in, first out" due to busy work; on the other hand, it increases the risk of accidental breakage of drugs during the transfer process.

[0004] At present, there is a medical injection box (application number: CN20231156432.5), which includes a box body and a box cover. A partition is arranged in the box body, and the partition divides the inner cavity space of the box body into two layers, an upper layer and an lower layer. A plurality of drug carriers are arranged in the box body, and the plurality of drug carriers are slidably arranged in the upper space and the lower space of the inner cavity of the box body. When no drug is loaded, the drug carrier can enter the lower space from the upper space of the box body; strip holes for the drug carrier to pass up and down are opened on the left and right sides of the partition, and the upper surface of the partition in the upper space of the box body is set to be higher on the left and lower on the right. When the drug carrier is located in the upper space of the box body, the drug carrier can move toward the right; the inner cavity bottom wall of the lower space of the box body is set to be lower on the left and higher on the right. When the drug carrier enters the lower space of the box body, the drug carrier can move toward the left; the application can automatically realize the left-in and right-out of drugs, so that the drugs approaching the expiration date are located on the right, and the newly placed drugs are located on the left, so as to avoid the situation where the drugs on the left are not taken for a long time, resulting in the expiration of the drugs or expiration. However, this design has the following two defects: First, because the injection box is equipped with a lid, the lid needs to be opened every time the medicine is used, which is inconvenient to use, especially in emergency moments when medical staff are rescuing patients; second, although the design realizes automatic "left in and right out, first in first out", its internal structure is relatively complex and the cost is high, so it is not easy to promote, and it is easy to damage and difficult to repair.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] The injection box in the prior art is provided with a box cover, which needs to be opened each time the medicine is used, which is inconvenient to take out, especially in the emergency moment when medical staff are rescuing patients; in addition, the internal structure of the existing injection box is relatively complicated, the cost is high, it is not easy to promote, and it is easy to damage and difficult to repair.

[0027] In view of the problems existing in the prior art, this embodiment provides a rolling injection storage and access device. Figure 1The storage and retrieval device includes a support frame 1, a tray 2, a rotating shaft 3 and a rotating wheel 4; the rotating shaft 3 is fixed at both ends of the support frame 1, the end of the rotating shaft 3 protrudes out of the side of the support frame 1, and the rotating wheel 4 is sleeved on the rotating shaft 3, and the rotating wheel 4 can rotate relative to the support frame 1 with the rotating shaft 3 as the center.

[0028] The tray 2 is an annular structure, which is wound around the periphery of the rotating wheel 4 at both ends of the support frame 1. The inner wall surface of the tray 2 and the outer periphery of the rotating wheel 4 are both provided with friction structures, and the tray 2 can drive the rotating wheel 4 to rotate through the friction between it and the rotating wheel 4. In this embodiment, a tooth-like protrusion 21 is provided on the tray 2, and a tooth-like depression is provided on the outer periphery of the rotating wheel 4. The tooth-like protrusion 21 on the tray 2 can mesh with the tooth-like depression on the rotating wheel 4, thereby realizing the transmission connection between the tray 2 and the rotating wheel 4. It can be understood that in other embodiments, a tooth-like depression can also be provided on the inner wall surface of the tray 2, and a tooth-like protrusion can be provided on the outer periphery of the rotating wheel 4, and the transmission connection between the tray 2 and the rotating wheel 4 can also be realized. The shapes of the above-mentioned tooth-like protrusion 21 and the tooth-like depression are matched, and the longitudinal cross-sectional shapes of the two can be regular or irregular shapes such as trapezoid, rectangle, triangle, semicircle, etc.

[0029] A plurality of containers 5 for storing injections are arranged on the outer wall surface of the tray 2 , and the plurality of containers 5 are spaced apart and distributed along the circumferential direction of the tray 2 .

[0030] In this embodiment, the tray 2 is made of a flexible material as a whole, and the tooth-like protrusions 21 on the tray 2 are made of a hard material fixed thereon.

[0031] In some other preferred embodiments, the tray 2 includes a plurality of storage units, each of which is provided with a container 5, and the storage units are connected by flexible nodes. Specifically, the flexible node includes a connecting rod and a pivot shaft, and the two ends of the connecting rod are rotatably connected to the storage unit through the pivot shaft. Alternatively, the flexible node includes a flexible member, and the two ends of the flexible member are fixedly connected to the storage units at both ends thereof by glue or a connecting member.

[0032] In this embodiment, the container 5 is a groove formed directly on the tray 2. In some other preferred embodiments, the container 5 may also be an independent component fixedly mounted on the tray 2. The shape of the container 5 may be rectangular or semi-cylindrical.

[0033] In order to facilitate taking the injection and pushing the tray 2, refer to Figure 2 In this embodiment, the length of the container 5 is greater than the length of the injection. With this design, when taking the injection, the medical staff can insert two fingers into the container 5 and place them on the two ends of the injection to take the injection. While taking the injection, they can also push the inner wall of the container 5 to push the tray 2 to move to the right.

[0034] like Figure 2 As shown, an embodiment that can accommodate 5 injections is schematically listed, wherein the 5 positions labeled "A, B, C, D, and E" are the positions for injections under normal conditions. After the medical staff takes an injection at the position labeled "A", they gently push the tray 2 to the right. The friction between the tray 2 and the rotating wheel 4 will cause the position labeled "F" on the tray 2 to move to the right and move it to the original position labeled "E". The supplementary injection can then be placed in the empty position labeled "F", ensuring that the injection at the position labeled "A" taken each time is a medicine that is closer to its expiration date, thereby simply realizing the "left in, right out, first in, first out" drug taking specification and ensuring the safety of the drug expiration date.

[0035] In order to prevent the medical staff from making the wrong direction when pushing the tray, resulting in the empty space on the right being moved to the left, deviating from the principle of "left in, right out, first in, first out", a direction indicator, such as an arrow, text, etc., is provided on the top surface of the tray 2 to instruct the medical staff to move the tray from left to right.

[0036] In some other preferred embodiments, refer to Figure 3 The storage and retrieval device further comprises a hollow shell 6, and the support frame 1 is suspended and fixed on the inner wall of the shell 6; or, the two ends of the rotating shaft 3 are rotatably mounted on the inner walls of the shell 6 on both sides. Further, the shell 6 also has a limiting portion 61, and the limiting portion 61 is located on the two outer sides of the tray 2, and a gap is reserved between the limiting portion 61 and the tray 2.

[0037] When the medical staff pushes the tray 2 too hard, causing the position of the injection that needs to be taken to move to the side of the rotating wheel 4 (i.e., in a position inclined to the horizontal plane), the injection will be at risk of falling. The limiting portion 61 of the housing 6 can limit the injection in the container 5 to prevent the injection from falling. At this time, the medical staff only needs to push the tray 2 in the opposite direction (to the left), and the injection that needs to be taken can return to a safe horizontal position.

[0038] In summary, by using the rolling injection storage and access device provided in this embodiment, when medical staff follow the principle of "left in and right out" to take one or more injections on the right side of the tray 2, they only need to give the tray 2 a force to the right end, and the tray 2 drives the rotating wheel 4 to rotate through friction, and the annular tray 2 rotates around the space formed by the rotating wheel 4 and the support frame 1 to move the empty space of the tray 2 (i.e., the empty container 5) to the leftmost side of the tray 2, which is convenient for medical staff to replenish medicines. Due to the coverless design, medical staff can quickly take medicines, which is easy to operate and meets the working specifications of "left in and right out, first in first out", greatly improving the efficiency of medicine replenishment and staff compliance.

[0039] In addition, the tray 2 and the rotating wheel 4 achieve synchronous rotation through the friction between the two, and the rotating shaft 3 and the supporting frame 1 remain stationary. The device has a simple structure, low cost, simple operation process, and is not easy to damage.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
