Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a refrigerating reagent bin. Background Art

[0002] When a coagulation analyzer performs sampling and analysis, a certain amount of reagent is sucked from the reagent bottle in the reagent bin. To ensure the safety of the reagent in the reagent bin, the reagent bin needs to reach and maintain a temperature of 2-8 °C within 30 minutes after startup through the refrigeration of the refrigeration system and the control of the temperature control system. At present, the temperature control of the reagent bin mostly adopts two forms: air cooling and water cooling to ensure the storage conditions of the reagent. For example, the refrigeration system of the medical instrument reagent bin disclosed in Patent CN206310789U and a reagent bin refrigeration structure and a reagent bin for eliminating condensed water disclosed in Patent CN210425624U.

[0003] When the existing reagent bin holds the reagent bottle, the reagent bottle is placed upright. Since the bottom of the reagent bottle is flat, when there is less reagent in the reagent bottle, the liquid level height of the reagent is relatively low. At this time, the reagent cannot be pumped out, resulting in a large amount of residual reagent in the reagent bottle and causing waste of the reagent. Summary of the Utility Model

[0004] Aiming at the above-mentioned deficiencies of the existing technology, the utility model provides a refrigerating reagent bin. Through the tray, the reagent bottle is placed obliquely in the bin body, reducing the dead volume of the reagent in the reagent bottle. The sampling needle can extend into the reagent bottle to pump out more reagent, reducing the residual amount in the reagent bottle and avoiding waste of the reagent.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A refrigerating reagent bin includes a bin body. A refrigerating component is connected to the bottom of the bin body. A detachable tray is connected to the upper end of the bin body. Handles are provided on both sides of the tray. Positioning holes for installing reagent bottles are provided at the upper end of the tray. A tray for supporting the bottom of the reagent bottle is provided below the positioning holes. The tray is inclined.

[0007] Preferably, a heat-insulating cotton is provided on the outer side of the bin body.

[0008] Preferably, a drainage groove is provided at the bottom of the inner cavity of the bin body, and a drainage hole is provided at the bottom of the drainage groove.

[0009] Preferably, positioning columns for positioning reagent bottles are provided in the bin body.

[0010] Preferably, the refrigeration assembly includes a housing. The upper end of the housing is connected to the bin body through a fixing plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, the reagent bottles are inclined in the bin body through the tray, reducing the dead volume of the reagent in the reagent bottles. When the sampling needle extends into the reagent bottles, more reagent can be extracted, reducing the residual amount in the reagent bottles and avoiding waste of the reagent. The tray can realize synchronous taking and placing of the reagent bottles, saving time.

[0014] 2. The present utility model adopts a dual heat dissipation method of heat pipes and heat dissipation fins, which can greatly accelerate the heat dissipation speed and improve the refrigeration effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1-2 shown, a refrigeration reagent bin includes a bin body 2, a refrigeration component 1 is connected to the bottom of the bin body 2, a detachable tray 3 is connected to the upper end of the bin body 2, and the tray 3 is directly placed on the upper end of the bin body 2. As Figure 3 shown, handles 302 are provided on both sides of the tray 3, positioning holes 303 for installing reagent bottles 4 are provided on the upper end of the tray 3, a tray 301 that supports the bottom of the reagent bottle 4 is provided below the positioning holes 303, the tray 301 is inclined, and both ends of the tray 3 are connected to the bottom of the tray 3 through pull plates 304. The bottom of the inner cavity of the bin body 2 is an inclined surface.

[0023] The reagent bottle 4 is placed obliquely in the tray 3. When there is less reagent, it can ensure that the reagent in the reagent bottle 4 has a sufficient depth, so as to facilitate the extraction of the reagent, greatly reduce the residual amount in the reagent bottle 4, and reduce the waste of the reagent.

[0024] In order to improve the refrigeration effect, heat insulation cotton 204 is provided on the outside of the bin body 2.

[0025] As Figure 4 shown, a drainage groove 202 is provided at the bottom of the inner cavity of the bin body 2, a drainage hole 203 is provided at the bottom of the drainage groove 202, the drainage hole 203 is connected to a drainage pipe, and the condensed water can flow into the drainage hole 203 along the drainage groove 202 and be discharged through the pipeline.

[0026] Positioning columns 201 for positioning the reagent bottle 4 are provided in the bin body 2. The positioning columns 201 are located between the four reagent bottles 4. Concave arc grooves are provided on the side walls of the positioning columns 201, which can cooperate with the side walls of the reagent bottle 4 to position the reagent bottle 4 and ensure the stability of the reagent bottle 4.

[0027] The refrigeration component includes a machine shell 105. The upper end of the machine shell 105 is connected to the bin body 2 through a fixing plate 5. A radiator is connected to the lower end of the fixing plate 5. A refrigeration device 103 is provided at the upper end of the radiator. A relief hole 501 that cooperates with the refrigeration device 103 is provided on the fixing plate 5. The upper end of the refrigeration device 103 is attached to the bottom of the bin body 2. Air guide covers 101 and fans 106 are respectively provided at both ends of the machine shell 105.

[0028] The radiator includes a heat conduction plate 102 connected to the fixing plate 5. The refrigeration device 103 is located at the upper end of the heat conduction plate 102. As Figure 5As shown, the lower end surface of the heat conducting plate 102 is connected with heat dissipation fins 104 and a heat pipe 107.

[0029] The heat pipe 107 is a heat transfer element with extremely high heat conduction performance. It transfers heat through the vapor-liquid phase change of the working fluid completely enclosed in a vacuum tube, and has extremely high heat conductivity, which is hundreds of times that of pure copper's heat conduction ability. The heat dissipation of the heat pipe 107 utilizes the good heat transfer performance of the heat pipe 107, and has the advantages of compact structure, large heat transfer capacity, convenient installation and small maintenance volume. The heat pipe 107 mainly transfers heat by the evaporation and condensation of the working fluid.

[0030] The heat pipe 107 generally consists of three parts: a pipe shell, a liquid absorption core and a working fluid. After evacuating the inside of the pipe to a relatively high vacuum degree, an appropriate amount of working fluid is filled, so that the capillary porous material closely attached to the inner wall of the pipe is filled with liquid and then sealed. The heat pipe 107 has two ends, namely an evaporation end and a condensation end, and heat insulation measures need to be taken between the two ends.

[0031] When one end of the heat pipe 107 is heated (that is, when there is a temperature difference between the two ends), the liquid in the capillary core evaporates and vaporizes, and the vapor flows to the other end under the pressure difference to release heat and condense into a liquid, and the liquid then flows back to the evaporation end along the porous material by capillary action.

[0032] In the solution, the refrigerating surface of the refrigerator 103 contacts the bottom of the bin body 2 to perform refrigeration and cooling. The bin body 2 is also provided with a temperature sensor to accurately control the temperature of the reagent bin. The heating surface of the refrigerator 103 contacts the heat conducting plate 102 of the radiator, transfers the heat to the heat conducting plate 102, and the heat of the heat conducting plate 102 is transferred to the evaporation end of the heat pipe 107, so that the liquid in the capillary core evaporates and vaporizes, and the vapor flows to the other end of the heat pipe 107 under the pressure difference to release heat and form a liquid, and then flows back to the evaporation end along the porous material by capillary action. Such a cycle continues continuously, and this cycle is carried out quickly, and the heat can be continuously conducted. At the same time, heat dissipation is carried out through multiple groups of fins provided, and the fan 106 increases the air flow to dissipate the heat on the heat dissipation fins 104, realizing fast and efficient refrigeration.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
