Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a mobile blood bank trolley. Background Art

[0002] With the development of medical technology and the growth of medical needs, mobile blood banks play an increasingly important role in medical rescue and blood management. Although existing mobile blood bank equipment has made certain progress in refrigeration and transportation, there is still room for improvement in terms of safety and operational convenience. Especially during blood transportation, ensuring the stability and safety of blood samples is crucial, and any loss of blood samples caused by improper operation or equipment failure may have a serious impact on medical treatment.

[0003] Deficiencies of the prior art:

[0004] 1. Problem of human resource consumption. The design of existing mobile blood bank equipment usually requires at least two staff members to cooperate in operation: one is responsible for opening the fixator, and the other is responsible for carrying the mobile blood bank. This design not only increases the consumption of human resources, but also prolongs the operation time and reduces work efficiency. In case of emergency, this manpower-dependent operation method may delay the treatment time and affect the treatment effect.

[0005] 2. Lack of locking device. The current transfer vehicles lack a locking device. When the operator places the equipment on the transfer vehicle, it is not locked or not fully locked, and the equipment is likely to move or fall due to vibration or accidental collision during transportation, resulting in the loss or damage of blood samples. The loss of blood samples not only causes waste of resources, but may also have an irreversible impact on the treatment of patients. Summary of the Utility Model

[0042] First Embodiment:

[0043] Referring to Figures 1 to 4 , the present utility model shows a mobile blood bank cart, which can be used to transport a blood storage box. Two snap grooves can be provided at intervals near the bottom position on the side of the blood storage box. The blood storage box can also be defined as a mobile blood bank.

[0044] In this embodiment, the mobile blood bank cart includes a carrying platform 10, a locking mechanism 20, and a moving mechanism 30.

[0045] The carrying platform 10 can be a plate-like structure. For example, the carrying platform 10 can be a rectangular plate-like structure. The carrying platform 10 is used for installing the locking mechanism 20 and the moving mechanism 30. The carrying platform 10 is provided with a push handle structure 11. Preferably, one end of the carrying platform 10 along the first direction is provided with the push handle structure 11. For example, when the carrying platform 10 is a rectangular plate-like structure, the first direction is the length direction of the carrying platform 10. The push handle structure 11 can be a U-shaped structure, and the push handle structure 11 can be an integral structure with the carrying platform 10. Of course, the push handle structure 11 can also be defined as a "handle structure", and no specific limitation is made here.

[0046] The locking mechanism 20 is provided on the carrying platform 10. The locking mechanism 20 includes a snap component 21 and an operating member 22. The operating member 22 is connected to the snap component 21 and is used to drive the snap component 21 to lock or unlock the blood storage box. The snap component 21 can be mutually engaged with the snap groove, which can avoid the situation that the blood storage box is displaced or even separated from the mobile blood bank cart when the mobile blood bank cart is moving, and improve the transportation safety of the blood storage box. It can be understood that the locking mechanism 20 can lock the blood storage box, so that the blood storage box will not move or fall accidentally during transportation, ensuring the transportation safety of blood samples.

[0047] The moving mechanism 30 is connected to the bearing platform 10 and is used to provide mobility so that the mobile blood bank trolley can move. The moving mechanism 30 may include support columns 31 and a moving component 32. The support columns 31 may be in a rectangular columnar structure or a circular columnar structure. The upper end of the support column 31 is connected to the bearing platform 10, and the lower end of the support column 31 is connected to the moving component 32. Preferably, the upper end of the support column 31 may be fixedly connected to the bearing platform 10 through a first fastener. The first fastener includes but is not limited to screws or bolts. The lower end of the support column 31 is fixedly connected to the moving component 32 through a second fastener. The second fastener includes but is not limited to screws or bolts.

[0048] Preferably, a first groove is provided at the bottom of the bearing platform 10. The moving component 32 includes a main body 321 and a plurality of feet 322 connected to the main body 321. The main body 321 is provided with a second groove. The upper end of the support column 31 is inserted and fixed in the first groove and is fixedly connected through a first fastener.

The first through hole 231 and the second through hole 232 are arranged at intervals in a first direction. Here, the first direction may be the length direction of the housing 23.

[0052] The buckle assembly 21 may include a positioning plate 211, on which a first buckle 212 and a second buckle 213 are provided. The first buckle 212 and the second buckle 213 are arranged at intervals along a first direction. The upper part of the first buckle 212 protrudes from the first through hole 231, and the upper part of the second buckle 213 protrudes from the second through hole 232. The positioning plate 211 may be generally in the shape of a rectangular plate, and the first direction here may be the length direction of the positioning plate 211.

[0053] The operating member 22 is connected to the positioning plate 211 to drive the positioning plate 211 to move along the first direction, so that the first buckle 212 and the second buckle 213 lock or unlock the blood storage box. For example, when the first buckle 212 and the second buckle 213 move to the left along the first direction, the blood storage box can be unlocked, and when the first buckle 212 and the second buckle 213 move to the right along the first direction, the blood storage box can be locked.

The operating member 22 includes a button switch, which is installed in the first mounting hole 233 and connected to one end of the positioning plate 211. Preferably, a vertical portion is provided at one end of the positioning plate 211, and the vertical portion is disposed opposite to the first mounting hole 233, so that the button switch can pass through the first mounting hole 233 and be connected to the vertical portion, thereby realizing the connection between the button switch and the positioning plate 211. Further, the button switch and the positioning plate 211 may be fixedly connected or detachably connected, and the button switch may be in the shape of a cube or a cylinder.

[0055] Among them, when the staff presses the button switch, the positioning plate 211 can be driven to move along the first direction through the button switch.

[0056] Preferably, the button switch may be entirely located within the first mounting hole 233, that is, the button switch does not protrude from the first mounting hole 233, which can prevent the buckle assembly 21 from being in an unlocked state when the staff accidentally touches the button switch during the movement of the mobile blood bank vehicle. Preferably, the button switch may include, but is not limited to, a fingerprint button switch, and only when the fingerprint information meets the requirements can the pressing operation be realized.
