Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a body fluid detection and preservation cabinet. Background Art

[0002] The liquid in the human body is composed of water and inorganic salts and organic matter dissolved in water, collectively referred to as body fluids. Body fluid testing is one of the common clinical testing items. It is generally done by collecting samples from patients, placing the collected samples in test tubes, and temporarily refrigerating the test tubes in a preservation cabinet or preservation box, waiting for unified testing. However, when using existing preservation cabinets or preservation boxes for storing test tubes, the cabinet door is generally opened to insert the test tubes into the test tube rack in the cabinet, or the cabinet door is opened to take the test tubes from the test tube rack. This way of use means that the cold air in the cabinet leaks out. On the one hand, energy consumption increases. On the other hand, the leakage of cold air means the temperature drops. When the cabinet door is frequently opened and closed, it is easy for the storage temperature of the remaining test tubes in the cabinet to fail to meet the preset temperature requirements, resulting in damage to the samples in the test tubes, affecting the accuracy of subsequent test results.

[0003] Based on the above, the present invention proposes a body fluid testing and storage cabinet which can significantly reduce the leakage of cold air when storing or taking out test tubes. Utility Model Content

[0004] In order to solve the problems mentioned in the above background, the utility model provides a body fluid testing and preservation cabinet.

[0027] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0028] Reference Figure 1-Figure 7 A body fluid testing and preservation cabinet includes a preservation cabinet body 1, in which an insulation box 3 is slidably installed. The cabinet door 2 of the preservation cabinet body 1 is opened, and the insulation box 3 can be pulled out or pushed back into the preservation cabinet body 1 through the handle 4 set on the insulation box 3, which is similar to the existing drawer technology. In addition, a refrigeration system is provided on the preservation cabinet body 1, and the refrigeration system is connected to the insulation box 3 for cooling the insulation box 3. This can be achieved with existing refrigeration technology and will not be elaborated on.

[0029] The cover of the heat preservation box 3 is provided with a plurality of inlet and outlet holes 5 in an array. The interior of the heat preservation box 3 is provided with supporting members 6 located below the inlet and outlet holes 5, and a plurality of supporting members 6 are provided accordingly.

[0030] The supporting member 6 is set to switch between a blocking state and a supporting state. When in the blocking state, the upper end of the supporting member 6 blocks the lower opening of the inlet and outlet hole 5. This state is also the initial state. When in the supporting state, the supporting member 6 is used to receive and support the test tube containing the body fluid sample. In addition, the state switching action of the supporting member 6 is pressing, that is, the test tube is directly inserted into the insulation box 3 through the inlet and outlet hole 5, and the supporting member 6 is switched from the blocking state to the supporting state. By slightly pressing the test tube, the supporting member 6 can be switched from the supporting state to the blocking state. It is more convenient to use and can greatly reduce the leakage of cold air when storing or taking the test tube. It should be noted here that it is to reduce the leakage of cold air, rather than completely prevent the leakage of cold air.

[0031] Reference Figure 3-Figure 5 The supporting member 6 includes a supporting seat 601 coaxially located below the inlet and outlet hole 5. A lug is extended from the outer surface of the supporting seat 601, and a convex pin is extended from the bottom of the lug. A spring 604 is provided between the convex pin and the bottom of the storage cabinet body 1. Preferably, two lugs are provided and are respectively located on both sides of the supporting seat 601. It should be noted here that in order to ensure the smooth and smooth up and down movement of the supporting seat 601, a vertically arranged sliding sleeve can be provided at the bottom of the storage cabinet body 1, and the convex pin and The sleeve forms a sliding fit, and the spring 604 is sleeved on the outside of the sleeve and the convex pin. In this scheme, the sleeve and the convex pin are not shown. Furthermore, initially, under the elastic force of the spring 604, the upper end face of the support seat 601 contacts the box cover of the insulation box 3. Since the outer diameter of the support seat 601 is larger than the aperture of the inlet and outlet hole 5, the lower opening of the inlet and outlet hole 5 is blocked. Preferably, the upper end face of the support seat 601 is coaxially provided with a support groove 602, and the bottom of the test tube is supported by the support groove 602.

[0032] A hook rod 603 made of elastic material extends from the bottom of the support seat 601. Several hook rods 603 are arranged in an array along the circumferential direction of the support seat 601. A hook claw extends from the bottom of the hook rod 603 toward the axis of the support seat 601. The bottom of the hook claw is provided with an inclined surface, and the distance between the inclined surface and the axis of the support seat 601 decreases from bottom to top.

[0033] The supporting member 6 also includes a fixed shaft 605 arranged at the bottom of the storage cabinet body 1 and coaxial with the inlet and outlet hole 5. A fixed seat 606 is provided at the upper end of the fixed shaft 605. The outer diameter of the fixed seat 606 decreases from bottom to top. The outer sliding sleeve of the fixed shaft 605 is provided with a movable seat 607. The outer diameter of the movable seat 607 first increases and then decreases from bottom to top. In addition, the bottom of the fixed seat 606 is also provided with a receiving groove for accommodating the decreasing outer diameter part of the movable seat 607. The maximum outer diameter of the movable seat 607 is equal to the maximum outer diameter of the fixed seat 606.

[0034] Initially, the distance between the movable seat 607 and the fixed seat 606 is greater than the vertical dimension of the hook.

[0035] The working principle of this utility model:

[0036] Open the cabinet door 2, pull out the insulation box 3, and insert the test tube into the insulation box 3 through the inlet and outlet hole 5. During the insertion process, the bottom of the test tube is located in the supporting groove 602, the supporting seat 601 moves downward, and the spring 604 is compressed. During the downward movement of the supporting seat 601, the inclined surface of the hook claw contacts the outer circular surface of the fixed seat 606, causing the hook rod 603 to undergo elastic deformation away from the axis of the supporting seat 601. Eventually, the hook claw will pass over the fixed seat 606, and at the same time, the hook rod 603 releases the elastic force, causing the hook claw to hook the fixed seat 606. Figure 6 As shown, at this point, the test tubes have been stored, the insulation box 3 is pushed back into the storage cabinet body 1, and the cabinet door 2 is closed;

[0037] When it is necessary to take out the test tube, the cabinet door 2 is opened, the heat preservation box 3 is pulled out, and the test tube is pressed so that the hook hooks the portion of the movable seat 607 with an increasing outer diameter. Then, the pressing is canceled, and the spring 604 releases its elastic force, causing the supporting seat 601 to move upward. When the supporting seat 601 moves upward, the movable seat 607 is moved upward together with the hook. When the portion of the movable seat 607 with a decreasing outer diameter is located in the receiving groove, as shown in FIG. Figure 7 As shown, the hook will then directly pass over the fixed seat 606, and the movable seat 607 will be driven by gravity to fall and reset, and the supporting seat 601 will continue to move upward until the inlet and outlet hole 5 is re-sealed, and the test tube will be pushed upward by the supporting seat 601. It should be noted that although the medical staff has released the pressure, their hands are still holding the test tube. After the test tube is taken out, the insulation box 3 is pushed back into the storage cabinet body 1 and the cabinet door 2 is closed.

[0038] In a preferred embodiment, an external step for supporting the movable seat 607 is provided on the fixed shaft 605 .

[0039] In a preferred embodiment, magnet one is embedded in the bottom of the accommodating groove, and magnet two is embedded in the upper end surface of the movable seat 607. The magnetic poles of magnet one and magnet two facing each other are the same, and they exert magnetic repulsion, and the magnetic repulsion is smaller than the friction between the hook and the movable seat 607. Its significance is to assist the movable seat 607 in moving down and resetting.

[0040] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
