Description

Technical Field

[0001] The utility model relates to the technical field of specimen processing, in particular to a digestive fluid-added weighing and heating incubation device for an integrated sputum pre-processing device. Background Art

[0002] Sputum, body fluids, feces and other tissue samples are commonly used microbiological test samples, among which sputum samples are the largest sample in China, accounting for about 70% of the total sample volume. So far, sputum culture is still the most widely used, simple, convenient, economical and safe etiological diagnostic technology.

[0003] Since sputum specimens have obvious heterogeneity and the distribution concentration of bacteria and other components is very uneven, the culture positive rate of real pathogens is greatly affected. With the rapid development of medical detection technology, heating and incubation devices have emerged. Heating and incubation devices are used to heat and incubate biological sample reaction liquids. Usually, the heating and incubation device is placed in a carrier equipped with biological sample reaction liquid, heats the carrier, and transfers heat to the biological sample reaction liquid in the carrier to achieve incubation of the biological sample reaction liquid in the carrier.

[0004] At present, when encountering sputum specimens containing a large amount of mucus in clinical practice, sputum pretreatment is usually performed, in which an equal amount of digestive fluid is added artificially, and then incubated and digested. This can digest the sputum from a jelly state to a liquid state, making the bacteria in the sputum more uniform, which is greatly beneficial to increase the positive rate of true pathogenic bacteria culture. Common weighing devices do not have a heating weighing function, resulting in the need for heating treatment of the material before it can continue to be weighed during the weighing process, resulting in a decrease in the efficiency of material weighing, which seriously affects the versatility of the weighing device. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, the utility model provides a sputum integrated pre-treatment device for adding digestive fluid to the weighing and heating incubation device.

[0006] The utility model is realized by the following technical scheme: a sputum integrated pre-treatment device is used for adding digestive fluid to weigh and heat incubation device, including a working platform, wherein the working platform is equipped with a weighing and heating device, a liquid adding device and a rotating mechanical arm device, the weighing and heating device includes an electronic balance, a weighing cylinder installed above the electronic balance, a heating plate is installed at the bottom of the weighing cylinder, and the outer wall of the weighing cylinder is surrounded and attached with a heat preservation layer;

[0007] The rotating mechanical arm device comprises a support base fixedly mounted on the working platform, an electric rotating platform is mounted on the top of the support base, a first mechanical arm and a second mechanical arm coaxially connected are mounted on the electric rotating platform, the first mechanical arm is located below the second mechanical arm and maintains a horizontal angle of 90°, and a capping machine is mounted at the end of the first mechanical arm;

[0008] The liquid adding device comprises a sample adding needle, a sample adding pump and a digestion solution storage bottle. The sample adding needle is vertically installed downward at the end of the second mechanical arm. The top of the sample adding needle is a liquid inlet end and is connected to the outlet end of the sample adding pump through a first hose. The inlet end of the sample adding pump is connected to the digestion solution storage bottle through a second hose.

[0009] The electronic balance, the heating plate, the electric rotating table and the sample adding pump are all communicatively connected to the information control device.

[0010] As a preferred solution, the heating plate is fixedly mounted on the bottom of the weighing cylinder by means of heat-conducting adhesive.

[0011] As a preferred solution, the sample adding needle is a steel sample adding needle.

[0012] As a preferred solution, the sample adding pump adopts a diaphragm pump.

[0013] As a preferred solution, the electronic balance is also equipped with an alarm unit, and the alarm unit is communicatively connected to the information control device.

[0014] As a preferred solution, the information control device is installed on the working platform, and the information control device is internally assembled as an information control system.

[0015] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model has the advantages of simple structure, convenient operation, and can be convenient for avoiding errors according to the detection quality. The sputum weight is weighed by a weighing and heating device to reflect the volume of the sputum from the weight aspect, and then the amount of sputum digestive fluid is added in a standardized manner according to the volume reflected by the weight, and the signal is transmitted to the information system. The system effectively solves the problem of manual evaluation of the sputum volume to add sputum digestive fluid and manual proportioning, which is inefficient, and realizes the purpose of automatically and accurately adding sputum digestive fluid to digest the sputum.

[0016] The utility model can automatically weigh and incubate and heat sputum through the weighing and heating device, greatly reducing errors and improving the accuracy of digestive juice. When in use, the product is placed in the weighing and heating device, the weight is calculated, and then the signal is transmitted to the information system. Then, according to the data fed back by the electronic balance, the liquid adding device starts to start, and the weight of the sputum reagent bottle is measured by the electronic scale, thereby realizing fully automatic weighing, heating and liquid adding.

[0017] The utility model has the advantages of providing a heating plate, adjusting the heating plate and the weighing device, improving the stability of the heating plate, and utilizing the heating plate to heat the inside of the weighing device, so that the weighing instrument itself has relatively good heating and weighing characteristics, improving the efficiency of the electronic balance in heating and weighing materials, and improving the versatility of the electronic balance. The entire system is coupled with a liquid adding device, which can improve the problems of low accuracy and cumbersome operation of traditional manual visual liquid adding. The electronic balance transmits the signal to the information system, and the information system realizes accurate, stable and automatic liquid addition of the digestive fluid through a diaphragm pump, saving manpower, improving the injection efficiency of the digestive fluid, and thus improving the pre-treatment efficiency of sputum samples, which is particularly suitable for the detection needs of high-channel samples in clinical practice.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] Combine the following Figure 1 to Figure 2The sputum integrated pre-treatment device of the embodiment of the utility model is specifically described by adding a digestive fluid weighing and heating incubation device.

[0027] like Figure 1 , Figure 2 As shown, the utility model proposes a sputum integrated pre-treatment device for adding digestive fluid to weigh and heat incubation device, including a working platform 1, wherein the working platform 1 is equipped with a weighing and heating device, a liquid adding device and a rotating mechanical arm device, and the weighing and heating device includes an electronic balance 2, a weighing cylinder 3 installed above the electronic balance 2, a heating plate 4 is installed at the bottom of the weighing cylinder 3, and the outer wall of the weighing cylinder 3 is surrounded and attached with a thermal insulation layer 5; the heating plate 4 is fixedly installed at the bottom of the weighing cylinder 3 by a thermal conductive adhesive. When working, the heating plate 4 generates heat and conducts the heat to the weighing cylinder 3. When the top surface of the heating plate 4 contacts the bottom surface of the weighing cylinder 3, the received heat can be transferred to the digestive fluid test tube in the weighing cylinder 3, so that the temperature of the biological sample reaction liquid in the digestive fluid test tube is increased, that is, the biological sample reaction liquid in the carrier can be incubated. Among them, the thermal insulation layer 5 can prevent the temperature of the heating plate 4 from diffusing outward, and play a good thermal insulation role, so that the heating plate 4 transfers most of the heat to the weighing cylinder 3, and has a good heating effect on the digestive fluid test tube. The weighing heating incubation device formed by the combination of the heating plate 4 and the heat-insulating layer 5 has a relatively simple structure, a reasonable layout, and a relatively small size.

[0028] The rotating mechanical arm device includes a support base 6 fixedly mounted on the working platform 1, an electric rotating platform 7 is mounted on the top of the support base 6, a first mechanical arm 8 and a second mechanical arm 9 coaxially connected are mounted on the electric rotating platform 7, the first mechanical arm 8 is located below the second mechanical arm 9 and maintains a horizontal angle of 90°, and a capping machine 10 is mounted at the end of the first mechanical arm 8;

[0029] The liquid adding device includes a sample adding needle 11, a sample adding pump 12 and a digestion solution storage bottle 13. The sample adding needle 11 is made of steel. The sample adding pump 12 adopts a diaphragm pump. The data information obtained from the injection is processed by the information system and transmitted to the diaphragm pump. The information system controls the opening and closing of the pump to control the flow rate of the digestion solution. The sample adding needle 11 is installed vertically downward at the end of the second robotic arm 9. The top of the sample adding needle 11 is the liquid inlet end and is connected to the outlet end of the sample adding pump 12 through the first hose 14. The inlet end of the sample adding pump 12 is connected to the digestion solution storage bottle 13 through the second hose 15;

[0030] The electronic balance 2, the heating plate 4, the electric rotating table 7 and the sample adding pump 12 are all communicatively connected to the information control device 16. The information control device 16 is installed on the working platform 1, and the information control device 16 is internally assembled as an information control system.

[0031] The electronic balance 2 is also equipped with an alarm unit, which is connected to the information control device 16. When the mass of the sputum does not match the mass of the digestive solution added, the alarm unit sends an alarm signal. When the weight of the sputum and the weight of the sputum digestive solution are lower than 1:1, an alarm signal is sent to remind the operator to check and verify, thereby improving the accuracy of the amount of liquid added.

[0032] The capping machine 10 is used to unscrew the test tube cap. The electronic balance 2 is used to weigh the weight and transmit the signal to the information control system of the information control device 16. The information control system controls the capping machine 10 to fix the test tube and open the cap. According to the weight reduction, the system calculates the mass of the digestion liquid. The information control system controls the sample pump 12 to add the digestion liquid in a ratio of 1:1.

[0033] Working process: First, the information control system records the weight M0 of the empty test tube. When the weighing cylinder 3 is placed with the test tube filled with sputum and covered with a test tube cap, the information control system controls the electric rotating table 7 to rotate the first mechanical arm 8 to the top of the weighing cylinder 3 and controls the capping machine 10 to unscrew the test tube cap. At this time, the total weight M1 of the test tube filled with sputum is recorded. Then, the information control system controls the electric rotating table 7 to rotate the second mechanical arm 9 to the top of the weighing cylinder 3 and controls the sample adding pump 12 to add the digestive solution in the digestive solution storage bottle 13 into the test tube according to the weight M2 of M1-M0, that is, the digestive solution is added to the test tube at a ratio of 1:1 to the sputum. After the addition is completed, the information control system controls the electric rotating table 7 to rotate the first mechanical arm 8 to the top of the weighing cylinder 3 and controls the capping machine 10 to screw the test tube cap back on the test tube. Finally, the information control system controls the heating plate 4 to heat the digestive solution test tube in the weighing cylinder 3, so that the temperature of the biological sample reaction liquid in the digestive solution test tube is increased, that is, the biological sample reaction liquid in the carrier can be incubated. The utility model realizes the standardized addition of sputum digestive fluid by weighing sputum, so that the bacteria in the sputum are more uniform, and the culture positive rate of real pathogenic bacteria is greatly improved.
