A raw material blood plasma refrigeration rack

Abstract

This utility model relates to the field of medical equipment technology and discloses a raw plasma refrigeration rack, including a cabinet. A blood storage tray is slidably connected inside the cabinet. A first shell is fixedly connected to the top of the blood storage tray. A second shell is sleeved inside the first shell. A lifting component is provided on the outer wall of the second shell. The lifting component includes a fixing block. One side of the fixing block is fixedly connected to the outer wall of the second shell. A locking block is rotatably connected inside the fixing block. A ratchet is fixedly connected to the inner wall of the first shell. In this utility model, the first shell has a ratchet and a return groove. When the second shell is pulled up, the locking block on its outer wall is squeezed by the ratchet. Then, the elastic plate rebounds at the plane of the ratchet. When it reaches the highest point, the directional teeth cause the locking block to turn in the return groove, and the second shell falls back to its original position by gravity. This achieves one-handed height adjustment, solves the problems of poor adaptability and inconvenient operation of traditional raw plasma refrigeration racks, and improves the efficiency of raw plasma refrigeration racks.

Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a raw blood plasma refrigeration rack. Background Technology

[0002] In the field of medical blood storage, the refrigerated preservation of raw plasma is a crucial step in ensuring its bioactivity and safety. Traditional plasma refrigeration racks typically employ a fixed, layered structure for suspending or placing plasma bags, maintaining a low-temperature environment through refrigeration equipment. These devices are widely used in blood banks, hospitals, and other facilities to meet the low-temperature requirements for plasma storage.

[0003] In existing technologies, raw plasma refrigeration racks mostly adopt rigid frame structures with fixed layer heights. Plasma bags are directly suspended or stacked via hooks or trays. Refrigeration typically relies on overall cabinet cooling or a cold air circulation system, using fans or ventilation holes to achieve uniform distribution of cold air. This type of structure is simple in design and can meet basic requirements for low-temperature plasma storage.

[0004] However, existing technologies have significant shortcomings: traditional raw plasma refrigeration racks have non-adjustable shelf heights, making them unsuitable for plasma bags of different sizes, resulting in low space utilization or unstable placement of the plasma bags. Furthermore, operation requires both hands for adjustment, which is extremely inconvenient in medical settings and impacts work efficiency. Therefore, there is an urgent need for a refrigeration rack structure that can be operated with one hand and is adaptable to various plasma bag sizes. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a raw plasma refrigeration rack, which aims to improve the problem that traditional raw plasma refrigeration racks cannot accommodate plasma bags of different sizes and cannot be adjusted with one hand when storing raw plasma.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a raw blood plasma refrigeration rack, including a cabinet, a blood storage tray slidably connected inside the cabinet, a housing one fixedly connected to the top of the blood storage tray, a housing two sleeved inside the housing one, and a lifting component provided on the outer wall of the housing two;

[0007] The lifting assembly includes a fixing block, one side of which is fixedly connected to the outer wall of the second housing. A locking block is rotatably connected inside the fixing block. A ratchet is fixedly connected to the inner wall of the first housing. A directional tooth is fixedly connected to the inner wall of the first housing. A return groove is opened on the inner wall of the first housing. An elastic sheet is fixedly connected to the outer wall of the second housing.

[0008] As a further description of the above technical solution:

[0009] An air conditioner is fixedly connected to the inner wall of the cabinet. The air conditioner is equipped with an air regulating plate. Rotary shafts are fixedly connected to both ends of the air regulating plate. One end of the rotating shaft is rotatably connected to the inner wall of the air conditioner.

[0010] As a further description of the above technical solution:

[0011] A cabinet door is rotatably connected to one side of the cabinet body. A handle is fixedly connected to the outer wall of the cabinet door. A label box is fixedly connected to the outer wall of the cabinet door. A temperature display is fixedly connected to the outer wall of the cabinet door.

[0012] As a further description of the above technical solution:

[0013] A limiting groove is formed on the inner wall of the first housing, and a limiting strip is fixedly connected to the outer wall of the second housing.

[0014] As a further description of the above technical solution:

[0015] A crossbeam is fixedly connected to the outer wall of the housing. A sliding groove is provided inside the crossbeam, and a hook is provided inside the crossbeam. The hook is slidably connected inside the sliding groove.

[0016] As a further description of the above technical solution:

[0017] A limiting opening is provided on one outer wall of the housing.

[0018] As a further description of the above technical solution:

[0019] The blood storage tray has a drain outlet inside.

[0020] As a further description of the above technical solution:

[0021] The cabinet is fixedly connected to a sliding strip, and a drip tray is slidably connected to the top of the sliding strip.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the second shell is fitted inside the first shell. Multiple ratchet teeth are fixedly connected inside the first shell. A return groove is opened on the inner wall of the first shell. When the second shell is pulled upward, the locking block on the outer wall of the second shell is squeezed by the ratchet inclined surface. Under the action of the elastic sheet fixed on the outer wall of the second shell at the ratchet plane, it rebounds. When the second shell is pulled to the highest position, the locking block rotates in the return groove in another direction under the action of the directional tooth inclined surface. Under the action of gravity, the second shell returns to its original position without being limited by the ratchet teeth. This achieves the ability to adjust the height of the stored plasma with one hand, solves the problem that the traditional raw plasma refrigeration rack cannot be used for plasma bags of different sizes and is inconvenient to operate with one hand, and improves the efficiency of the raw plasma refrigeration rack.

[0024] 2. In this utility model, an air conditioner is fixed to the inner wall of the cabinet. The air conditioner passes through the space between the two shells and cools the plasma bags along the way. The air outlet of the air conditioner is directed at the plasma bags hanging on the hooks. The inner wall of the air conditioner is rotatably connected to a shaft, and one end of the shaft is fixedly connected to an air regulating plate. The air supply angle is adjusted according to the height of the plasma bags. Each layer of plasma bags is equipped with an air conditioner for cooling, which achieves precise temperature control of the plasma cold storage rack. This solves the problem of inaccurate temperature control and uneven temperature of the plasma storage environment in traditional plasma cold storage racks, and improves the practicality of raw plasma cold storage racks.
