Description

Technical Field

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

[0002] The 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 the set temperature, and the set time is maintained at the set temperature so that the biological samples and the added reagents can fully react. For example, the urine aldosterone test item in the secondary hypertension screening index of the endocrinology department requires the urine sample to be hydrolyzed first, and then the aldosterone (ALD) concentration in the urine matrix is ​​tested by chemiluminescence. Among them, the hydrolysis operation process includes adding a certain amount of hydrochloric acid to the urine specimen, and then placing the urine specimen to which the quantitative hydrochloric acid has been added in a 30°C water bath for 18 hours for hydrolysis. The water bath process needs to be carried out under constant time and constant temperature conditions. If the hydrolysis exceeds the set time, it is likely to cause the test results to be high; if the hydrolysis time is less than the theoretical time, it may cause insufficient hydrolysis and low test results. Therefore, whether the water bath time is too long or too short, it may affect the test results and ultimately affect the subsequent treatment.

[0003] At present, for the water bath step of biological samples that needs to be carried out under constant time and temperature conditions, the water bath duration is generally determined based on the reaction time of the corresponding test item, and the heating temperature of the water bath is regulated based on the theoretical reaction temperature.

[0004] In fact, the constant temperature reaction time of biological samples in the water bath process will be affected by at least the following factors: (1) the temperature of the biological sample before the water bath; (2) whether the water bath box is always maintained in a relatively closed heating environment during the water bath process.

[0005] However, the temperature of the biological sample before the water bath usually does not meet the theoretical reaction temperature. Generally, it takes a period of time in the water bath for the biological sample to reach the corresponding reaction temperature. In addition, the testing department usually has 1-2 water baths, which are placed in batches in the water bath for water bath treatment according to the sample delivery time and the required water bath time. That is to say, in the process of water bathing a batch of biological samples, especially biological samples that require a longer water bath time, the water bath in which they are located will generally be opened at least once. In this way, it is difficult to ensure that the water bath can be maintained in a closed water bath environment for a long time, and there will generally be a certain amount of heat loss. Therefore, in fact, the reaction time of the biological sample at the set reaction temperature is less than the water bath time, and there is a situation where the biological sample does not get a sufficient water bath reaction.

[0006] Based on the above actual situation, the water bath conditions of biological samples are generally difficult to meet the testing requirements of constant temperature and constant time in the water bath, which can easily affect the test results and may ultimately affect subsequent treatment.

[0035] The present application will be further described below in conjunction with the accompanying drawings and exemplary embodiments, wherein the same reference numerals in the accompanying drawings all refer to the same components. In addition, if the detailed description of the known technology is not necessary for illustrating the features of the present application, it will be omitted.

[0036] In view of the technical problem that during the water bathing process of the water bath in the current medical examination water bath, the water bathing conditions of biological samples are generally difficult to meet the inspection requirements of the water bath constant temperature and constant time, which is easy to affect the inspection results and may ultimately affect the subsequent treatment, the present application provides a timed water bath test tube rack.

[0037] refer to Figure 1-3 , Figure 1 A schematic diagram of the three-dimensional structure of a water bath test tube rack provided in one embodiment of the present application. Figure 2 for Figure 1 A schematic structural diagram of a cross section of a water bath test tube rack in the AA direction provided in the embodiment, Figure 3 For this application Figure 1 A schematic diagram of the water bath timing connection structure of the water bath test tube rack provided in the embodiment.

[0038] The present application provides a timed water bath test tube rack 100, which at least includes: a bracket 110, a patch temperature sensor 120, a timer 130 and a reminder 140. In this embodiment, the bracket 110 is composed of a top plate 111 and four side plates 112 to form a support space Z with an opening 114 facing downward, and the height of the bracket 110 is greater than or equal to the liquid height of the biological sample in the test tube 200. The height of the bracket 110 is equal to the height of the side plates 112 of the bracket 110.

[0039] Since the amount of biological sample injected into the test tube 200 is within the set range, the liquid height of the biological sample in the test tube 200 is within a certain range. If the reaction solution is added, the liquid height is between 3-4 cm. Correspondingly, in this embodiment, the height of the bracket 110 is greater than or equal to 4 cm. During the water bath, the entire bracket 110 is below the water surface of the water bath, that is, the top plate 111 is located below the water surface of the water bath, and the water body of the water bath can enter the inside of the test tube sleeve 113. At this time, the tube section where the biological sample is located can be completely immersed in the water body of the water bath for water bath treatment, thereby ensuring the water bath effect.

[0040] Along the vertical direction of the support 110, the support 110 is provided with a plurality of test tube sleeves 113, which are used to place the test tubes 200. The diameter of the test tube sleeve 113 is larger than the diameter of the placed test tube 200. The bottom end of the test tube sleeve 113 does not exceed the bottom end of the side plate 112 of the support 110, that is, the test tube sleeve 113 is completely placed in the support space Z of the support 110, which protects the test tube sleeve 113 and ensures the stability of the entire water bath test tube rack 100 when placed.

[0041] For a single test tube sleeve 113, at least one connecting hole 115 is provided at the bottom thereof, and the connecting hole 115 can connect the inside and the outside of the test tube sleeve 113. During the water bath process, the water bath water can circulate between the opening 114 of the test tube sleeve 113 located on the top plate 111 and the connecting hole 115, so that the temperature of the water bath water can be transferred to the biological sample in the test tube 200 in the test tube sleeve 113 more quickly, thereby realizing the water bath treatment of the biological sample.

[0042] In this embodiment, the connecting hole 115 is located at the bottom of the test tube sleeve 113, so that the water in the water bath can circulate through the entire pipe section between the opening 114 of the top plate 111 and the connecting hole 115, further ensuring that the biological samples at various heights in the test tube 200 receive the same water bath temperature transfer treatment. More preferably, the connecting hole 115 is offset from the center position of the bottom of the test tube sleeve 113, so as to avoid the test tube 200 causing the clogging of the connecting hole 115 and hindering the water circulation in the test tube sleeve 113 and affecting the water bath treatment effect, and provide sufficient flow space for the water in the test tube sleeve 113.

[0043] Furthermore, the patch temperature sensor 120 is covered on the inner wall of the test tube sleeve 113 corresponding to the biological sample in the test tube 200. Specifically, it can be on the inner wall of the test tube sleeve 113 corresponding to the upper biological sample and the lower biological sample in the test tube 200. When the corresponding temperatures are consistent, it can be inferred that the overall temperature distribution of the biological sample is also uniform and consistent, and this is used as the start time of the water bath treatment, thereby avoiding the problem of uneven heating of the biological sample in the test tube 200 affecting the temperature monitoring data, and providing more accurate temperature data for the control of the constant temperature water bath.

[0044] like Figure 1-2As shown, in this embodiment, the patch temperature sensor 120 covers the inner wall of the test tube sleeve 113 to form a temperature monitoring sleeve. More preferably, the edge of the patch temperature sensor 120 is flush with the edge of the test tube sleeve 113, and the patch temperature sensor 120 covers the entire inner wall of the test tube sleeve 113. In this way, on the basis that the height of the support 110 is greater than or equal to the liquid height of the biological sample in the test tube 200, the patch temperature sensor 120 can basically wrap the entire tube section where the biological sample in the test tube 200 is located, and the overall temperature of the biological sample in the test tube 200 is monitored, so as to accurately control the water bath time, and ensure that the overall temperature of the biological sample in the test tube 200 can meet the temperature requirements of the water bath and the water bath treatment is carried out under the condition that temperature stratification does not occur.

[0045] In addition, the patch temperature sensor 120 reserves a first through hole 121 at the connection hole 115, so that the water in the water bath can be connected to the space in the patch temperature sensor 120. During the water bath, the test tube 200 injected with the biological sample and / or the reaction solution is placed in the temperature monitoring tube sleeve formed by the patch temperature sensor 120 in the test tube sleeve 113. Due to the connection hole 115 of the test tube sleeve 113 and the first through hole 121 corresponding to the patch temperature sensor 120, the water in the water bath can circulate in the temperature monitoring tube sleeve formed by the patch temperature sensor 120, and the test tube 200 is subjected to water bath treatment. In addition, since the patch temperature sensor 120 is completely wrapped in the outer wall of the pipe section injected with the biological sample in the form of a temperature monitoring tube sleeve, the patch temperature sensor 120 can fully monitor the temperature of the entire pipe section injected with the biological sample.

[0046] In a general water bath treatment, the constant time and constant temperature conditions of the water bath of the biological samples in all the test tubes 200 in the same water bath test tube rack 100 are the same. Based on this situation, the working principle of the water bath test tube rack 100 provided in the above embodiment is: by covering the inner wall of the test tube sleeve 113 corresponding to the biological sample in the test tube 200 with a patch temperature sensor 120, the temperature of the biological sample in the test tube 200 is monitored. When the biological samples in all the test tubes 200 in the same water bath test tube rack 100 reach the preset water bath temperature, such as when the temperature of the corresponding tube section of the biological sample obtained by each patch temperature sensor 120 reaches the constant temperature condition of 37 degrees, the overall temperature of the biological sample injected into the test tube 200 also reaches 37 degrees. At this time, the monitoring signal reaching 37 degrees triggers the timer 130 to start, and the timer 130 counts down according to the preset time length. The end signal of the countdown triggers the prompter 140 to issue a prompt message, such as issuing a prompt sound or turning on a prompt light. Based on the design of this solution, the problem of determining the starting time of the water bath duration, which is affected by the biological sample reaching the water bath temperature and the heat loss in the water bath box, is solved.

[0047] Based on the water bath test tube rack 100 provided in the above-mentioned embodiment of the present application, a plurality of vertical test tube sleeves 113 can be arranged on a support frame 110 with an opening 114 facing downwards, which can be completely placed in a water bath water body, and at least one connecting hole 115 is arranged at the bottom of each test tube sleeve 113, so that the tube section where the biological sample of each test tube 200 is located can be completely immersed in the water bath water body circulating between the opening 114 of the test tube sleeve 113 and the connecting hole 115 for water bath treatment, thereby avoiding the situation where the water bath effect is affected by the uneven temperature of the biological sample in the test tube 200. In addition, the patch temperature sensor 120 having a first through hole 121 opened in the corresponding connecting hole 115 in each test tube sleeve 113 can cover the inner wall of the test tube sleeve 113 corresponding to the biological sample in the test tube 200, so as to obtain the temperature data of the tube section where the biological sample of each test tube 200 is located, and the time when the temperature data reaches the preset water bath temperature is used as the start time of the water bath treatment, and the monitoring signal reaching the water bath temperature is used as the trigger start signal of the timer 130, so that the water bath treatment of the biological sample can be started under the condition of a constant temperature water bath, and the completion signal based on the countdown of the timer 130 is used as the signal to trigger the reminder 140, so that the biological sample can fully meet the test requirements of constant temperature and constant time for water bath treatment, thereby ensuring the accuracy of the test data and providing accurate data support for subsequent treatment.

[0048] refer to Figure 4-6 , Figure 4 This is a schematic diagram of the three-dimensional structure of a water bath test tube rack provided in another embodiment of the present application. Figure 5 for Figure 4 A schematic structural diagram of a cross section of a water bath test tube rack in the BB direction provided in the embodiment, Figure 6 For this application Figure 4 A schematic diagram of the water bath timing connection structure of the water bath test tube rack provided in the embodiment.

[0049] The optimized design based on the water bath test tube rack 100 provided in the above embodiment is as follows:

[0050] The water bath test tube rack 100 also includes: a support plate 150 and a connecting column 160. The support 110 and the support plate 150 located above are parallel to each other, and a plurality of connecting columns 160 are vertically connected between the two. There is a hollow portion L between the support frame and the support 110. The support plate 150 is provided with a plug hole 151 corresponding to the position of each test tube sleeve 113. The test tube 200 in each test tube sleeve 113 passes through the plug hole 151 to the bottom of the corresponding test tube sleeve 113.

[0051] In this embodiment, the support plate 150 serves as the upper surface of the water bath test tube rack 100 in this embodiment. During the water bath, the water surface of the water bath is located above the support plate 150. The water in the water bath can reach the opening 114 of the test tube sleeve 113 through the hollow portion L and enter each test tube sleeve 113, and circulate with the water in the water bath through the connecting hole 115.

[0052] Correspondingly, the patch temperature sensor 120 is respectively attached to the bottom of the inner wall of each test tube sleeve 113 and the plug hole 151. Specifically, the patch temperature sensor 120 includes: a bottom patch temperature sensor 122 and a plug hole patch temperature sensor 123. The bottom patch temperature sensor 122 includes a flexible material and can be attached to the bottom of the test tube sleeve 113, and a second through hole 1221 is reserved at the bottom patch temperature sensor 122 corresponding to the connecting hole 115. The bottom patch temperature sensor 122 is used to monitor the temperature of the lower biological sample in the test tube 200.

[0053] For the jack 151, the jack patch temperature sensor 123 is clamped in the jack 151. The jack patch temperature sensor 123 includes: a fixing ring 1231 and at least one temperature sensing spring 1232. The first side of the temperature sensing spring 1232 is fixed inside the fixing ring 1231, and the second side extends toward the center line of the jack 151. The temperature sensing spring 1232 includes elastic material. When the jack 151 is inserted with a test tube 200, the temperature sensing spring 1232 opens outward, and simultaneously monitors the temperature of the upper biological sample in the test tube 200, and fixes and limits the test tube 200.

[0054] The fixing ring 1231 can be a fully closed ring or a semi-closed ring. The cross-sectional structure of the fixing ring 1231 in the direction perpendicular to the support plate 150 is a U-shaped structure. The fixing ring 1231 is clamped between the upper surface and the lower surface of the support plate 150.

[0055] Furthermore, the socket patch temperature sensor 123 includes at least two temperature sensing springs 1232, and at least two temperature sensing springs 1232 are arranged opposite to each other, so as to generate symmetrical clamping forces on the opposite sides of the test tube 200 inserted in the socket 151, ensuring that the test tube 200 stands firmly in the water bath in a vertical state during the water bath process.

[0056] In addition, the edge shape of the second side of the temperature sensing spring 1232 is set to be a concave arc in the direction of the center line of the socket 151, and the concave arc reserves an avoidance space for the outer wall of the test tube 200. In addition to realizing the functions of the temperature sensing spring 1232 to monitor the temperature of the test tube 200 and to fix and limit the test tube 200, it can also make it easier to insert and remove the test tube 200 from the water bath test tube rack 100.

[0057] In the above embodiment, the timer 130 is connected to the bottom SMD temperature sensor 122 and the jack SMD temperature sensor 123 respectively, and the timer 130 is connected to the prompter 140 .

[0058] The working principle of the water bath test tube rack 100 provided in this embodiment is: the temperature of the upper biological sample and the lower biological sample of the test tube 200 are monitored by the bottom patch temperature sensor 122 and the plug-in patch temperature sensor 123 respectively. When the temperature data obtained by the two are consistent, it can be inferred that the temperature distribution of the biological sample in the test tube 200 is uniform and the overall temperature is consistent. When the monitoring temperatures obtained by the bottom patch temperature sensor 122 and the plug-in patch temperature sensor 123 both reach the preset water bath temperature, the monitoring signals of the two temperature data reaching the standard are used as the triggering conditions of the timer 130, and the timer 130 is triggered to start. The timer 130 counts down according to the preset time length, and the countdown completion signal triggers the prompter 140 to send a prompt message, such as a prompt sound or a prompt light.
