Description

Technical Field

[0001] This utility model relates to the field of sample detection technology, and in particular to a sample storage box for microbial detection. Background Technology

[0002] Microbial testing refers to the process of using artificially prepared culture media and artificially created culture conditions, such as culture temperature, to enable certain microorganisms to grow and reproduce rapidly, followed by comprehensive observation of these microorganisms. Sample storage boxes are often used in the process of microbial testing to store and collect microbial test samples.

[0003] A search of Chinese utility model patent (publication number CN221795411U) reveals a storage box for microbial testing samples. The external box utilizes an internal electric cylinder structure that, through a threaded sleeve, drives a connecting rod to adjust the height of a placement plate within the storage box. This allows for easy adjustment of the placement plate's height within the storage box, accommodating test tubes of different lengths. Furthermore, a rotating top cover causes a pressure plate to gradually press down on the top of the test tubes located on the placement plate, prompting the deflection rod on the damping spring to quickly adapt and adjust, ensuring the test tubes are stably stored within the storage box.

[0004] However, practical application has revealed that this technical solution still has at least the following drawbacks:

[0005] The placement plate used to fix the test tubes in this design can only be adjusted in height to accommodate test tubes of different lengths, but it cannot be adapted to test tubes of different thicknesses. Furthermore, the adjustment process for multiple placement plates is quite cumbersome. In addition, the placement plate, which is made of rigid material, directly contacts the test tubes, lacking protection for them and thus failing to provide adequate shock resistance and impact protection. Utility Model Content

[0006] This invention aims to provide a sample storage box for microbial detection to solve the problems mentioned in the background art. This solution uses multiple sleeves to hold test tubes and utilizes inflatable air bladders within the sleeves to clamp and fix the test tubes. The inner cavities of the multiple air bladders are interconnected and expanded synchronously by a single air pump. The air pressure is uniform at all locations within the cavities, ensuring a consistent clamping force on all test tubes. It is suitable for test tubes of various lengths and thicknesses, and the fixing process is simple and quick. Simultaneously, the air bladders themselves are filled with air, providing shock absorption. Being made of flexible material, they allow the test tubes to be suspended and fixed, providing excellent shock resistance and collision protection. The overall structure of the device is simple, rationally designed, and highly practical.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sample storage box for microbial detection includes a box body. The inner cavity of the box body is provided with sleeves arranged at equal intervals. The inner ends of the sleeves are connected to air bladders. A connecting tube is connected between two adjacent sleeves, and the inner cavities of two adjacent sleeves are connected through the connecting tube. The connecting tube is connected to the inner cavity of the sleeve. The two outermost sleeves are connected to the inner wall of the box body. A control console is connected to the inner wall of the box body. An air pump is connected inside the control console. The output end of the air pump is connected to the inner cavity of one of the air bladders.

[0009] Preferably, the airbag is arranged around the inner wall of the airbag, and the inner wall of the airbag is connected with a dense array of anti-slip textures.

[0010] Preferably, the inner wall of the box is connected to a bracket, and the inner end of the bracket is connected to a pair of symmetrical sponge blocks, which are positioned above the sleeve.

[0011] Preferably, a pair of sponge blocks abut against each other, and each pair of sponge blocks has multiple positioning grooves arranged at equal intervals at one end.

[0012] Preferably, the number of positioning grooves on one of the sponge blocks is the same as the number of sleeves, and the positioning grooves are located directly above the sleeves.

[0013] Preferably, a pressure sensor is connected to the inner wall of one of the sleeves, the pressure sensor is disposed in the inner cavity of the airbag, and the pressure sensor is electrically connected to the control console.

[0014] Preferably, an ice pack box is slidably connected to the bottom of the inner wall of the box, and one end of the ice pack box extends to the outside of the box.

[0015] Preferably, the ice pack box has a partition above it that matches the shape of the inner cavity of the box. The partition has a hollow structure and is connected to the inner wall of the box.

[0016] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0017] This design uses multiple sleeves to hold test tubes, and inflates air bladders within the sleeves to clamp and fix the test tubes. The inner cavities of the multiple air bladders are interconnected and expanded synchronously by a single air pump. The air pressure is uniform throughout the cavities, ensuring that all test tubes are clamped and fixed with the same compressive force. This design is suitable for test tubes of various lengths and thicknesses, and the fixing process is simple and quick. Furthermore, the air bladders themselves, filled with air, provide shock absorption and are made of flexible material, allowing the test tubes to be suspended and fixed, providing excellent shock resistance and collision protection. The overall structure of the device is simple, rationally designed, and highly practical. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0025] like Figure 1-5 The sample storage box for microbial detection shown includes a box body 1. The inner cavity of the box body 1 is provided with sleeves 3 arranged at equal intervals. The inner ends of the sleeves 3 are all connected to air bags 4. A connecting pipe 5 is connected between two adjacent sleeves 3, and the inner cavities of two adjacent sleeves 3 are connected through the connecting pipe 5. The connecting pipe 5 is connected to the inner cavity of the sleeve 3. The two outermost sleeves 3 are connected to the inner wall of the box body 1. A control console 2 is connected to the inner wall of the box body 1. An air pump is connected inside the control console 2. The output end of the air pump is connected to the inner cavity of one of the air bags 4.

[0026] Microbial testing refers to the process of using artificially prepared culture media and artificially created culture conditions, such as culture temperature, to enable certain microorganisms to grow and reproduce rapidly, followed by comprehensive observation of these microorganisms. Sample storage boxes are often used in the process of microbial testing to store and collect microbial test samples.

[0027] In this design, the user can place multiple test tubes inside multiple sleeves 3, allowing the air bladders 4 inside the sleeves 3 to surround the test tubes. The control console 2 is equipped with a display and control buttons to control the start and stop of the air pump inside the control console 2. The user controls the air pump to start via the control console 2, and the air pump injects air into one of the air bladders 4, causing it to expand. Since the multiple air bladders 4 are connected through multiple connecting pipes 5, the multiple air bladders 4 will expand synchronously, ultimately squeezing and clamping the outer walls of the multiple test tubes. With this setup, there is no need to consider the length and thickness of the test tubes. Since the inner cavities of the multiple air bladders 4 are connected as a whole, the air pressure at each position is the same, which can form the same squeezing force to clamp and fix all the test tubes. At the same time, the air bladders 4 themselves are filled with air, which has a shock absorption effect. They are also made of flexible material, which can suspend and fix the test tubes, providing them with good shock resistance and anti-collision protection.

[0028] Airbag 4 is arranged around the inner wall of airbag 4, and the inner wall of airbag 4 is connected with dense anti-slip texture.

[0029] In this design, the airbag 4 surrounds the test tube to clamp it, so that the outer wall of the test tube is subjected to uniform force and the fixation effect is stabilized. The anti-slip texture on the inner end of the airbag 4 can effectively enhance the friction between the support 6 and the test tube, ensuring that the test tube and the airbag 4 are relatively stationary and preventing the test tube from falling off.

[0030] The inner wall of the housing 1 is connected to a bracket 6, and the inner end of the bracket 6 is connected to a pair of symmetrical sponge blocks 7. The sponge blocks 7 are positioned above the sleeve 3. The pair of sponge blocks 7 abut against each other, and each pair of sponge blocks 7 has multiple positioning grooves 8 arranged at equal intervals at one end. The number of positioning grooves 8 on a sponge block 7 is the same as the number of sleeves 3. The positioning grooves 8 are positioned directly above the sleeve 3.

[0031] In this design, a pair of sponge blocks 7 can be used to position and temporarily fix the test tubes. Before the airbag 4 inflates, the user inserts the test tubes into the corresponding positioning slots 8, suspending them inside the sleeve 3 and keeping the tops of each test tube flush. Since the sponge blocks 7 are made of flexible material, test tubes of various sizes can be inserted.

[0032] A pressure sensor is connected to the inner wall of one of the sleeves 3. The pressure sensor is located in the inner cavity of the airbag 4 and is electrically connected to the control console 2.

[0033] This solution uses a pressure sensor to monitor the air pressure inside the airbag 4 in real time and feeds it back to the display on the control panel 2. Since the internal cavities of multiple airbags 4 are connected and the air pressure in each part is the same, one pressure sensor is sufficient. By monitoring the air pressure, the user can precisely control the start and stop of the air pump to avoid the airbag 4 from over-inflating and damaging the test tube, or under-inflating and causing the test tube to be unstable.

[0034] An ice pack box 9 is slidably connected to the bottom of the inner wall of the box 1. One end of the ice pack box 9 extends to the outside of the box 1. A partition 10 matching the shape of the inner cavity of the box 1 is provided above the ice pack box 9. The partition 10 is designed with a hollow structure and is connected to the inner wall of the box 1.

[0035] In this solution, the user can pull out the ice pack box 9 from inside the box 1 and place ice packs inside the ice pack box 9 to meet the requirement of keeping some samples at a low temperature. The pull-out ice pack box 9 makes it easy for the user to replace the ice packs at any time. The partition 10 can prevent the ice packs from contacting the bottom of the test tubes and avoid impact damage to the test tubes.

[0036] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
