Description

Technical Field

[0001] The utility model relates to the technical field of biological culture, in particular to a hookworm larva culture device for feces that prevents drying. Background Technique

[0002] Hookworms are common intestinal parasites that parasitize the human body. Their infection can cause symptoms such as severe anemia, malnutrition, and growth retardation in humans. The main hookworms that parasitize humans in China are Necator americanus and Ancylostoma duodenale. The pathogenicity and sensitivity to anthelmintic drugs of the two hookworms are different. Therefore, in order to improve the treatment effect of hookworm infection, it is necessary to identify the species of hookworms. Currently, the commonly used method for species identification is to culture feces using the test tube filter paper culture method, and identify the species by observing the morphology of hookworm larvae.

[0003] The existing test tube filter paper culture method includes the following steps: Take 5g - 10g of fresh feces and place them in a feces sampling box or sampling bag, mark the sample number to be tested and the collection date. The sample should be sent for inspection in a timely manner. Mark the sample number to be tested and the date on the test tube. Add about 2 mL of distilled water at room temperature to the test tube. Fold the filter paper strip along the long axis to keep it straight. Use a scraping rod to take 0.3g - 0.5g of feces and evenly smear it on the upper part of the middle section of the filter paper, leaving about 0.5 cm on each side, about 1 cm at the upper end, and about 2.5 cm at the lower end blank. Insert the filter paper with feces smeared into the test tube. The depth of the filter paper inserted into the water should be such that the lower edge of the fecal film is 1 cm above the water surface. Place the test tube in an incubator and culture at 31°C for 4 days, or at room temperature of 26°C - 30°C for 6 - 8 days to complete the culture of hookworm larvae.

[0004] However, when culturing hookworm larvae in the test tube using an incubator, it is necessary for the staff to stay on duty to observe the water volume at the bottom of the tube, and add distilled water along the tube wall to maintain the original liquid level height to prevent drying. However, the staff often cannot stay on duty to observe the water volume at the bottom of the tube for 24 hours. The water volume in the test tube will gradually evaporate and decrease due to the influence of the culture environment temperature, making the culture environment in the test tube too dry, affecting the culture of hookworm larvae in feces, and resulting in a significant decrease in the detection rate.

The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0022] Please refer to Figures 1 to 5 , the present invention provides a hookworm larvae culture device for preventing drying in feces. The hookworm larvae culture device for preventing drying in feces includes a test tube rack 101, a plurality of test tubes 102 and two dropping mechanisms. A plurality of placing grooves 103 are provided on both sides of the test tube rack 101, and each of the test tubes 102 is placed in each of the placing grooves 103. The two dropping mechanisms are provided on both sides of the test tube rack 101;

[0023] Each of the dropping mechanisms includes a translation guide rail 104, a driving assembly, a sliding seat 105, a water tank 106, a water pump 107, a first arm 108, a feeding tube 109, a second arm 110 and a camera 111. The translation guide rails 104 are provided on both sides of the test tube rack 101, and the sliding seats 105 are slidably provided on each of the translation guide rails 104. The driving assemblies are provided inside each of the translation guide rails 104, and the output ends of the driving assemblies are connected to the sliding seats 105. The water tanks 106 and the water pumps 107 are provided on each of the sliding seats 105. The first arms 108 are provided at the tops of each of the sliding seats 105, and the feeding tubes 109 are provided on the first arms 108. The second arms 110 are provided at the bottoms of each of the sliding seats 105, and the cameras 111 are provided on the second arms 110. The input end of the water pump 107 is connected to the water tank 106, and the output end of the water pump 107 is connected to the feeding tube 109.

[0024] In this embodiment, the liquid level at the bottom of the corresponding test tube 102 is observed in real time through the camera 111. If the water volume in the current test tube 102 is too low, the water pump 107 is started, and the distilled water in the water tank 106 is transported into the corresponding test tube 102 through the addition tube 109, so that the liquid level in the current test tube 102 reaches the original liquid level height. Then, the driving assembly is started to drive the sliding seat 105 to slide on the translation guide rail 104, so that the sliding seat 105 slides to another test tube 102, and the above steps are repeated to complete the addition of distilled water into another test tube 102. With the above structure, the liquid level in the test tube 102 can always be maintained at the original liquid level height, thereby avoiding the test tube 102 being in a dry environment and affecting the cultivation of hookworm larvae in feces.

[0025] Further, one end of each addition tube 109 away from the water pump 107 is provided with a bent structure inclined to the side.

[0026] In this embodiment, since the output end of the addition tube 109 is provided with a bent structure inclined to the side, the distilled water transported through the addition tube 109 can be added into the test tube 102 along the inner wall of the test tube 102.

[0027] Further, each driving assembly includes a storage battery 112, a servo motor 113, a threaded rod 114, and a ball screw nut pair 115.

Since the ball screw nut pair 115 is connected to the sliding seat 105, the sliding seat 105 is driven to slide on the translation guide rail 104.

[0029] Further, sliding feet 116 are arranged on both sides of each sliding seat 105, and sliding grooves 117 are arranged on both sides of each translation guide rail 104. Each sliding foot 116 is respectively slidably connected to the corresponding sliding groove 117.

[0030] In this embodiment, through the arrangement of the sliding feet 116 and the sliding grooves 117, the sliding seat 105 slides on the translation guide rail 104.

[0031] Furthermore, on both sides of one side of each sliding seat 105 close to the corresponding translation guide rail 104, mounting grooves 118 are provided. A plurality of balls 119 are arranged inside the mounting grooves 118, and the balls 119 are in contact with the end faces of the translation guide rails 104.

[0032] In this embodiment, through the arrangement of the mounting grooves 118 and the balls 119, when the sliding seat 105 slides on the translation guide rail 104, the sliding is smoother.

[0033] Furthermore, a rotating bearing 120 is provided at one end of each translation guide rail 104 away from the corresponding servo motor 113, and a rotating head 121 is provided at one end of each threaded rod 114 away from the servo motor 113. The rotating head 121 is embedded inside the rotating bearing 120.

[0034] In this embodiment, through the arrangement of the rotating bearing 120 and the rotating head 121, when the threaded rod 114 rotates, the structure is more stable.

[0035] The above-disclosed is only a preferred embodiment of the present utility model, and of course, it cannot be used to limit the scope of rights of the present utility model. Those of ordinary skill in the art can understand the whole or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
