Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a blood collection test tube rack. Background Art

[0002] The hematology department, also known as the department of hematology, is a branch of internal medicine, mainly treating diseases of the hematopoietic system, that is, blood diseases. Checking various indicators in the body through blood tests is a basic reference for doctors to judge diseases. The hematology department usually uses a test tube rack to place test tubes.

[0003] When using the test tube rack, medical staff insert the test tube into the placement groove. At this time, the test tube rack has a limiting effect on the test tube and cannot clamp the test tube. When the medical staff moves the test tube rack, it will drive the test tube rack to move, resulting in the test tube shaking relative to the test tube rack.

[0004] Chinese patent document CN114849822A discloses a test tube rack for the hematology department, including a base. The upper end of the base is provided with a placement member for placing test tubes and a clamping mechanism for clamping the test tubes on the placement member. The placement member includes a U-shaped movable strip and a fixed cylinder. A fixed rod is fixedly installed on the U-shaped movable strip, and a movable ring is sleeved on the fixed rod. A compression spring is sleeved on the fixed rod between the U-shaped movable strip and the movable ring. The clamping mechanism includes an elastic rubber strip and a movable rod. The elastic rubber strip is arranged inside the fixed cylinder. A second installation groove is opened on the inner side of the U-shaped movable strip. The movable rod is movably installed inside the second installation groove. One end of the movable rod is fixedly installed with a pull rope, and the other end of the pull rope is connected to the movable ring. Its purpose is to solve the problem that when medical staff move the test tube rack, it will drive the test tube rack to move, resulting in the test tube shaking relative to the test tube rack.

[0005] However, the structure of this clamping mechanism is relatively complex, the operation is also relatively complicated, and it cannot achieve the heat preservation function. Since the collected blood cannot maintain the required correct temperature continuously during the mixing process and the journey to the laboratory for inspection, especially in extremely hot or extremely cold weather, too high or too low temperature may lead to a decrease in blood activity, affecting the test results and increasing the risk.

[0006] Therefore, developing a blood collection test tube rack that can both clamp and keep warm has practical application significance and real demand. Summary of the Utility Model

[0007] In view of this, to solve the above technical problems, the purpose of the present utility model is to propose a blood collection test tube rack, which can not only achieve the clamping function of the blood collection test tube, but also achieve the heat preservation function of the blood collection test tube.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] See Figures 1-3 As shown, a blood collection test tube rack includes a base 1, on which there are a plurality of test tube slots 2 for inserting blood collection test tubes. A heat preservation layer 3 is sleeved in the test tube slot 2. The heat preservation layer 3 is made of a rubber and plastic insulation material in the form of a sleeve inserted and fixed in the test tube slot. The upper end of the sleeve is provided with a conical inlet 31. The inner diameter of the top 32 of the conical inlet 31 is larger than the outer diameter of the blood collection test tube, and the inner diameter of the bottom 33 of the conical inlet 31 is smaller than the outer diameter of the blood collection test tube, so that the blood collection test tube can be firmly inserted into the heat preservation layer under the elastic action of the heat preservation layer.

[0026] Among them, the rubber and plastic insulation material is an existing material or a commercially available material. This rubber and plastic insulation material is generally a mixed foaming material mainly made of rubber and polyvinyl chloride (NBR / PVC), which is formed by mixing, kneading, continuous extrusion, heating and foaming, and cooling and slitting. This rubber and plastic insulation material is an elastic closed-cell foaming material, which has the characteristics of low thermal conductivity, fire prevention and flame retardancy, moisture and humidity resistance, and noise protection.

[0027] The sleeve made of the rubber and plastic insulation material is inserted and can be directly bonded and fixed in the test tube slot. This rubber and plastic insulation material has both heat preservation function and elastic function. Therefore, it can be combined and applied in the blood collection test tube rack.

[0028] Since the inner diameter of the top of the conical inlet is larger than the outer diameter of the blood collection tube, and the inner diameter of the bottom of the conical inlet is smaller than the outer diameter of the blood collection tube, on the one hand, the conical inlet can play a role in guiding the blood collection tube and is convenient for insertion; on the other hand, when inserted into the sleeve, due to the elastic effect of the heat preservation layer, the blood collection tube can be clamped. That is, it is realized that the blood collection tube can be firmly inserted into the heat preservation layer under the elastic effect of the heat preservation layer, so as to realize the clamping function and heat preservation function of the heat preservation layer.

[0029] Moreover, the heat preservation layer can also play a role in protecting and reducing noise for the blood collection tube. For example, when medical staff move the blood collection tube storage rack, since the blood collection tube is clamped, the impact sound generated when the blood collection tube shakes can be avoided. When the hand accidentally hits the blood collection tube, the heat preservation layer has a protective effect.

[0030] As a specific implementation manner, the inner diameter of the bottom of the conical inlet is 0.5 - 1 mm smaller than the outer diameter of the blood collection tube. The inner diameter of the top of the conical inlet is 1 - 5 mm larger than the outer diameter of the blood collection tube. Thus, the inner diameter of the bottom of the conical inlet is slightly smaller than the outer diameter of the blood collection tube, and the inner diameter of the top of the conical inlet is slightly larger than the outer diameter of the blood collection tube. Therefore, the slightly larger top is convenient for introduction, and the slightly smaller bottom is convenient for elastic clamping.

[0031] As a specific implementation manner, an inverted U-shaped handle 4 is fixed to the base 1. In this way, it is convenient for medical staff to carry the blood collection tube storage rack by hand.

[0032] As a specific implementation manner, the base includes a left half and a right half. The upper surface of the left half rises in a stepped shape from left to right; the upper surface of the right half descends in a stepped shape from left to right; the left half is provided with a plurality of test tube slots 2 for inserting blood collection tubes; each step of the right half is provided with a receiving cavity; the top of each receiving cavity is provided with a lid 6 connected by a hinge, and the lid 6 is the upper surface plate 6 of the right half. It can be further preferably that a drawer 5 is provided on the side of the base 1, and a handle 51 is provided on the front outer wall of the drawer. On the one hand, the height difference of the steps is convenient for medical staff to place a plurality of blood collection tubes, and is also convenient for observation and taking. That is, in the case where a plurality of blood collection tubes are stored in the blood collection rack, medical staff can quickly and accurately distinguish the required blood collection tube according to the height difference and step markings of the ladder layer, reducing the time spent in discrimination and improving work efficiency. On the other hand, a plurality of receiving cavities and drawers can be used to place blood collection needles, blood collection tubes connected to the blood collection needles, cotton swabs, tourniquets, disinfectants, anticoagulants and other blood collection tools. In this way, the protective personnel can directly carry the blood collection tube storage rack to collect blood for patients, reducing the time for preparing blood collection tools in the early stage and being able to be directly used during blood collection, which greatly facilitates medical staff. Among them, if blood is detected, no anticoagulant is placed in the blood vessel; if serum is detected, an anticoagulant needs to be placed in the blood vessel.

[0033] In summary, the blood collection test tube rack can keep the blood in the blood collection test tube warm through the heat preservation layer, reduce the influence of external temperature changes on the blood in the blood collection test tube, solve the problem that the blood in the medical field is prone to coagulate due to unsuitable environmental temperature during blood collection and sample delivery, and avoid the problem that the blood sample quality is affected by too high or too low temperature, resulting in inaccurate test results.

[0034] Through the elastic effect of the heat preservation layer, the problem of looseness during the movement of the blood collection test tube rack is solved.

[0035] Through the clamping function of the heat preservation layer on the blood collection test tube, the impact sound generated when the blood collection test tube shakes can be avoided. When the hand accidentally hits the blood collection test tube, the heat preservation layer also has a protective effect.

[0036] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present utility model, and they are not intended to limit the protection scope of the present utility model. Any equivalent embodiments or changes made without departing from the technical spirit of the present utility model shall be included in the protection scope of the present utility model.
