Description

Technical Field

[0001] The present application relates to the technical field of medical testing instruments, and in particular, to a water bath for medical testing. Background Art

[0002] A water bath is one of the commonly used sample processing equipment for biological sample testing in medical institutions. It is usually used for preheating of biological samples so that the biological samples can reach a set temperature and / or maintain a set time period at a set temperature so that the biological samples and the added reagents can fully react. At present, a general water bath has a heating tube installed at the bottom of its body, and a support plate with multiple holes is installed on the heating tube for placing biological samples. The operating principle of the existing water bath is to transfer heat to the liquid (such as water) in the water bath by controlling the heating temperature of the heating tube, and after a certain period of heating treatment, the biological samples in each test tube placed in the immersion area of ​​the water bath can meet the preheating requirements and / or the temperature conditions for reacting with the reagents. Among them, the immersion area is the area in the water bath located in the water.

[0003] However, the heating tube of the existing water bath generally cannot completely cover the bottom of the entire immersion area, and the stainless steel shell usually used for the water bath body has the problem of heat conduction with the outside. In addition, during the water bath process of one group of biological samples, the water bath will usually cause heat loss in the water bath due to the addition or removal of biological samples from other groups. As a result, the temperature of the immersion area of ​​the water bath near the water bath shell and the water surface area often cannot reach the expected heating temperature, resulting in different temperature environments for biological samples in test tubes located in different immersion areas, or biological samples at different heights in the same test tube, affecting the effect of the pre-heating treatment of the biological samples, thereby easily causing greater inspection deviation problems. Summary of the invention

[0004] In order to solve the problem that different temperature environments exist in water baths currently used for medical examinations, which affects the effect of preheating treatment of biological samples and easily leads to increased test deviations, the present application provides a water bath for medical examinations.

[0005] The water bath for medical examination provided in the present application comprises at least: a box body, a box cover covering the opening of the box body, at least one group of heating tubes, and an air supply device arranged near the heating tubes; wherein the air supply device comprises: at least one air supply tube, and an air pump connected to the air supply tube, the air pump is located outside the immersion area of ​​the water bath, the air supply tube is located in the immersion area and connected to the air pump, a plurality of air holes are arranged on the air supply tube, and each of the air holes faces the corresponding heating tube.

[0006] In an optional embodiment, the air supply pipe is arranged non-contact with the heating pipe, and is arranged parallel to or staggered with the heating pipe.

[0007] In an optional embodiment, the air supply pipe is located below the corresponding heating pipe; wherein, all the air holes of the same air supply pipe are equidistant from the corresponding heating pipe in a direction perpendicular to the water surface.

[0008] In an optional embodiment, the distance between the air supply pipe and the heating pipe in a direction perpendicular to the water surface is between 1 and 2 times the diameter of the air hole.

[0009] In an optional embodiment, at least two groups of the heating tubes are arranged in the box body, the air supply pipe is arranged in parallel between the two groups of the heating tubes, and at least two groups of air holes are arranged on the air supply pipe, and each group of air holes faces the corresponding heating tube above.

[0010] In an optional embodiment, the two groups of air holes are spaced apart from each other.

[0011] In an optional embodiment, the air supply pipe is arranged on the inner wall of the water bath parallel to the heating pipe, and the air supply pipe and the heating pipe are located in the same horizontal plane.

[0012] In an optional embodiment, the heating tube is a U-shaped heating tube, which includes at least two mutually parallel heating branches, the air supply pipe and the heating branch are parallel to each other, at least two groups of air holes are arranged on the air supply pipe, each group of air holes is arranged in a direction corresponding to a heating branch separately, and the groups of air holes on the same air supply pipe are arranged at intervals from each other.

[0016] Based on the water bath for medical examination provided in the embodiments of the present application, based on the air supply device added near the heating tube, the air supply tube connected to the air pump corresponds to the heating tube, and each air hole is made to face the corresponding heating tube, so that the air holes transmitted through the air supply tube disturb the water in the water bath, thereby accelerating the diffusion rate of the heat of the heating tube, thereby greatly improving the situation that the existing water bath can only rely on the natural diffusion of the heating tube to easily form a temperature difference between water bodies in different areas. Therefore, no matter whether the water body is close to or far away from the heating tube, and is located in different depth areas, the water temperature can be roughly the same at the same time, so as to achieve the purpose of evenly distributing heat in the entire water body in the immersion area of ​​the water bath, and ensure that the water bath effect of each biological sample can meet the expected medical examination requirements.

[0031] The present application provides a water bath box 100 for medical examination, which at least includes: a box body 110, a box cover 120, and at least one set of heating tubes 130 and an air supply device 140. During the water bath, the heating tubes 130 are immersed in the heating medium inside the box body 110, and the medium is generally water. Among them, the box body 110 is mainly made of stainless steel, and the box cover 120 covers the opening of the box body 110, which is used to physically isolate the water bath environment inside the box body 110 from the external environment of the box body 110, so as to slow down the heat loss inside the box body 110.

[0032] Generally, a support plate 150 is also provided in the water bath 100, and the support plate 150 is located above the heating tube 130. During the water bath, the water surface S of the immersion area 101 in the water bath 100 is located above the support plate 150. The support plate 150 is provided with a plurality of through holes (not shown) penetrating the water surface S and the heating tube 130, and the area of ​​the water surface of the water bath of the entire water bath 100 is the same. The support plate 150 is used to provide a placement platform for biological samples to be treated in the water bath, wherein each biological sample is generally placed in a plurality of corresponding test tubes 200, and is uniformly placed on the support plate 150 with a test tube rack 201.

[0033] In order to clearly show the structural features of the water bath directly used for preheating treatment, Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 The schematic diagram of the structure in the top view is a schematic diagram in a state where the support plate 150 is removed. Figure 2 , Figure 5 , Figure 7 , Fig. 9 The support plate 150 is indicated in the form of a dotted line.

[0034] In this embodiment, the heating tube 130 is connected to a heating device 131 , and the heating device 131 is located outside the immersion area 101 of the water bath 100 .

[0035] Further, in this embodiment, the air supply device 140 includes: an air supply pipe 141, and an air pump 142 connected to the air supply pipe 141. The air supply pipe 141 is located in the immersion area 101 during the water bath process, and the air pump 142 is arranged outside the immersion area 101. In this embodiment, the heating device 131 connected to the heating pipe 130 and the air pump 142 connected to the air supply pipe 141 are arranged in the device area 102 of the water bath box 100, and the device area 102 is isolated from the immersion area 101 to ensure moisture-proof and leakage-proof.

[0036] In this embodiment, a water bath 100 includes an air supply device 140, and the number of the air supply pipe 141 is at least one. The air supply pipe 141 is arranged near the heating pipe 130. On each air supply pipe 141, an air hole 1411 is arranged, and the air hole 1411 can supply the gas generated by the air pump 142 to the water bath 100, and its function is to disturb the water body through the gas, so that the heat emitted by the heating pipe 130 can be evenly distributed in the entire immersion area 101, and the immersion area 101 specifically includes the area close to or far away from the heating pipe 130 in the water bath 100, and the area at different water depths.

[0037] More specifically, in this embodiment, each air hole 1411 in the air supply pipe 141 faces the corresponding heating pipe 130 , so that the heat generated by the heating pipe 130 can be diffused to the entire immersion area 101 in the water bath 100 more quickly.

[0038] Based on the water bath 100 for medical examination provided in the embodiment of the present application, based on the air supply device 140 added near the heating tube 130, the air supply tube 141 connected to the air pump 142 corresponds to the heating tube 130, and each air hole 1411 is made to face the corresponding heating tube 130, so that the air holes 1411 transmitted through the air supply tube 141 disturb the water body in the water bath 100, thereby accelerating the diffusion speed of the heat of the heating tube 130, thereby greatly improving the situation that the existing water bath 100 can only rely on the natural diffusion of the heating tube 130 to easily form a temperature difference between water bodies in different areas. Therefore, whether it is close to or far away from the heating tube 130, and located in different depth areas, the water temperature can be roughly the same at the same time, so as to achieve the purpose of uniformly distributing heat in the entire water body of the immersion area 101 in the water bath 100, and ensure that the water bath effect of each biological sample can meet the expected medical examination requirements.

[0039] In order to more clearly distinguish the heating tube 130 and the gas supply tube 141 in the drawings of the specification, the heating tube 130 is shown in the drawings of the specification in a manner of filling with shadows.

[0040] Based on the above embodiment, the air supply pipe 141 is non-contact with the heating pipe 130, and the positional relationship between the heating pipe 130 and the air supply pipe 141 can be parallel to each other or cross-arranged, such as Figure 1-3 .in, Figure 1-2 The positional relationship between the heating tube 130 and the air supply tube 141 in the water bath 100 in one embodiment is shown from different angles: the air supply tube 141 is located directly below the heating tube 130 and is arranged parallel to each other. The air hole 1411 of the air supply tube 141 is facing upward, that is, the direction where the heating tube 130 is located. Figure 3, another embodiment is shown, the water bath 100 includes two groups of heating tubes 130, and two air supply pipes 141 located below the heating tubes 130, the two air supply pipes 141 are vertically arranged with the heating tubes 130, and the air holes 1411 thereof are facing upward. In this embodiment, the air supply pipes 141 disturb the water around the heating tubes 130 by spraying gas into the water, so as to accelerate the diffusion of heat. In addition, the angle between the air supply pipes 141 and the heating tubes 130, in addition to being parallel and vertical to each other, can also be staggered at other angles.

[0041] For the above-mentioned embodiment, for the same air supply pipe 141, the distance between each air hole 1411 and its corresponding heating pipe 130 in the direction perpendicular to the water surface is equal, so that the force of the gas ejected from each air hole 1411 on the corresponding heating pipe 130 is consistent, so that the diffusion speed of different sections of the heating pipe 130 is the same, and the impact force of the gas on each section is also the same, thereby further ensuring that the heat diffusion speed in the immersion area 101 is stable, and ensuring the stability of the equipment inside the water bath 100. In this embodiment, the distance between the air supply pipe 141 and the heating pipe 130 in the direction perpendicular to the water surface is 1 to 2 times the diameter distance of the air hole 1411. It can not only ensure that the gas output from the air hole 1411 has a good diffusion effect on the heat of each heating pipe 130, but also ensure that the heating pipe 130 can withstand the impact of the gas on it, thereby ensuring the safety and stability of the equipment in the water bath.

[0042] On the basis of the above embodiment, if at least two groups of heating tubes 130 are arranged in the box 110, the air supply pipe 141 can be arranged parallel to the two groups of heating tubes 130. In addition, corresponding groups of air holes 1411 are arranged corresponding to the number of groups of heating tubes 130 in the air supply pipe 141. Figure 4-5As shown, two groups of heating tubes 130 are arranged in the box 110, which are 130a and 130b respectively, and the air supply pipe 141 is located below the two groups of heating tubes 130 and between the two groups. Two groups of air holes 1411 are correspondingly opened on the air supply pipe 141, which are 1411a and 1411b respectively. The air hole 1411a corresponds to the heating tube 130a, and the air hole 1411a is arranged toward the heating tube 130a; the air hole 1411b corresponds to the heating tube 130b, and the air hole 1411b is arranged toward the heating tube 130b. In addition, the two groups of air holes 1411a and 1411b are arranged at intervals from each other. Specifically, the two groups of air holes 1411a and 1411b are arranged at intervals of one air hole 1411. Such a design enables the two groups of heating pipes 130a and 130b to receive the same exhaust volume and be evenly distributed, thereby ensuring that the heat diffused by the gas ejected from the two groups of air holes 1411a and 1411b to the heating pipes 130a and 130b is the same, which helps to ensure that the heat between water bodies in different areas is also the same.

[0043] Apart from Figure 1-5 In the embodiment where the air supply pipe 141 is located below the heating pipe 130, the air supply pipe 141 may be located on one side of the heating pipe 130. Figure 6-7 In the embodiment provided, the air supply pipe 141c is arranged on the inner wall of the water bath 100 parallel to the heating pipe 130c. In addition, the air supply pipe 141c and the heating pipe 130c can be located on the same horizontal plane, and the air hole 1411c is oriented to the location where the heating pipe 130c is located.

[0044] In addition, the air supply pipe 141 can also be located above the heating pipe 130, and the heat of the heating pipe 130 can be diffused to the surroundings by disturbing the water. At this time, the air holes 1411 on the air supply pipe 141 in this embodiment are oriented downward to where the heating pipe 130 is located.

[0045] In addition to the above-mentioned embodiment including a linear heating tube 130, the heating tube 130 can also be a U-shaped heating tube. For the U-shaped heating tube, at least two mutually parallel heating branches are included. Corresponding to the structure of the U-shaped heating tube 130, the air supply pipe 141 and the heating branch in this embodiment are parallel to each other. For an air supply pipe 141, at least two groups of air holes 1411 are provided. Each group of air holes 1411 is separately arranged in the direction of one of the heating branches. Moreover, each group of air holes 1411 on the same air supply pipe 141 is arranged at intervals from each other.

[0046] like Figure 8-9In the provided embodiment, the U-shaped heating pipe in the embodiment includes 4 heating branches, which are 130d, 130e, 130f and 130g. A corresponding air supply pipe 141 is set at the lower position between every two adjacent heating branches. Since the U-shaped heating pipe in the embodiment includes 4 heating branches, 3 corresponding air supply pipes 141 are set in the water bath 100, which are 141de, 141ef and 141fg, and all three are located at the same horizontal height below the U-shaped heating pipe. Among them, the air supply pipe 141de corresponds to the heating branches 130d and 130e, the air supply pipe 141ef corresponds to the heating branches 130e and 130f, and the air supply pipe 141fg corresponds to the heating branches 130f and 130g.

[0047] Two groups of air holes 1411 are provided on each air supply pipe 141, and each group of air holes 1411 is provided toward the corresponding heating branch pipe. For air supply pipe 141de, its air hole 1411d is provided toward heating branch pipe 130d, and air hole 1411e1 is provided toward heating branch pipe 130e; for air supply pipe 141ef, its air hole 1411e2 is provided toward heating branch pipe 130e, and air hole 1411f1 is provided toward heating branch pipe 130f; for air supply pipe 141fg, its air hole 1411f2 is provided toward heating branch pipe 130f, and air hole 1411g is provided toward heating branch pipe 130g.

[0048] In this embodiment, the air supply pipe 141 is located directly below the midpoint of the vertical connection line between each two adjacent heating branches, so the air supply pipe 141 is equidistant from the heating branches, forming an isosceles triangle. The center lines of the two groups of air holes 1411 on the air supply pipe 141 are complementary to the horizontal plane.

[0049] For the water bath 100 provided in any of the above embodiments, the exhaust volume per hour of the air supply device 140 is 1 / 5 to 1 / 6 of the set water volume in the immersion area 101. For example, if the specification of a water bath 100 is 1000×700×800mm, that is, the volume of the immersion area 101 is 0.56 cubic meters, and the set water volume is 0.18 cubic meters, the corresponding exhaust volume is 0.18 cubic meters / hour, which can ensure that the entire water body in the water bath 100 is sufficiently disturbed, and the degree of disturbance will not cause collisions between the test tubes 201 in the water due to the disturbance.
