Description

Technical Field

[0001] This utility model relates to a microbial sampling device, specifically a medical clinical microbial detection sampling device, belonging to the field of medical sampling technology. Background Technology

[0002] Medical clinical microbiology testing involves performing procedures such as microbial isolation, culture, identification, and drug sensitivity testing on patient samples (such as blood, urine, and respiratory secretions) to detect and analyze the types, quantities, and characteristics of microorganisms in the samples. This reveals the specific pathogens causing the patient's infection and provides important evidence for the diagnosis and treatment of infectious diseases.

[0003] After the microbial samples from the patient are extracted, they need to be sent to the laboratory for testing, which takes a certain amount of time. Sometimes, due to the busy work of the testing personnel or other reasons, the microbial samples cannot be tested immediately after sampling. Traditional microbial testing sampling equipment does not have the function of ensuring the activity of microbial samples. Many microorganisms, after leaving the human body, may experience stress responses due to sudden changes in environment and temperature, and may die quickly or enter a dormant state, thus affecting the accuracy of subsequent tests.

[0004] To address these issues, we provide a medical clinical microbiology testing and sampling device. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This medical clinical microbial detection and sampling device is equipped with a medicine bottle and a heating wire. A specific microbial preservation solution is injected into the medicine bottle, and the heating wire generates heat when energized to heat the medicine bottle, making it simulate the body temperature of the human body. This provides microorganisms with temperature conditions close to their original living environment, which helps maintain their activity from the time they are removed from the human body until the test. This allows the test results to more accurately reflect the true situation of the microorganisms in the human body and avoids the rapid death or dormancy of microorganisms after they are removed from the human body due to unsuitable temperature, which would affect the accuracy of subsequent tests.

[0015] 2. This medical clinical microbial testing sampling device is equipped with an air bladder. Pressing the air bladder creates negative pressure in the sample extraction tube, which draws the microbial sample into the air bladder through the sampling head. Then, the sample delivery tube is held vertically, allowing the microorganisms to fall into the medicine bottle, thus completing the sample collection. This device uses negative pressure generated by the air bladder to draw microbial samples, making it simpler to operate compared to some complex mechanical aspiration devices. Furthermore, the sample delivery tube, air bladder, sample extraction tube, and sampling head are all disposable, effectively avoiding cross-infection and ensuring that each patient's sample collection is independent and uncontaminated.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figure 1 — Figure 5 The storage box 1 includes a heating wire 2 inside the storage box 1. The heating wire 2 is a resistance wire, which generates heat when energized. Power supply blocks 11 are provided on both sides of the storage box 1. The power supply blocks 11 are connected to the heating wire 2 and can provide power to it. A handle is connected to the side of the power supply block 11 to facilitate the movement of the storage box 1. A current adjustment button 12 is provided on the upper end of the power supply block 11. The current adjustment button 12 is used to adjust the current supplied by the power supply block 11 to the heating wire 2, thereby adjusting the power of the heating wire 2, thereby adjusting the amount of heat generated and changing the temperature inside the storage box 1.

[0024] The storage box 1 has a placement slot 3, the heating wire 2 is located on both sides of the placement slot 3, and the power supply block 11 is equipped with a temperature sensor 13. The detection head of the temperature sensor 13 is located on the side of the placement slot 3. The temperature sensor 13 is used to detect the temperature inside the placement slot 3.

[0025] The placement slot 3 contains a medicine bottle 4, which is filled with a specific microbial preservation solution. The composition of the preservation solution is adjusted according to the survival requirements of the microorganism, such as containing appropriate amounts of nutrients and buffers to maintain the activity of the microorganism. The medicine bottle 4 is made of sterile transparent medical glass or high-quality medical plastic for easy observation of the sample's condition. A sealing cap 5 is provided at the top of the medicine bottle 4. The inner wall of the sealing cap 5 has a threaded groove, and it is connected to the medicine bottle 4 by a threaded connection, so that the sealing cap 5 can be removed from the medicine bottle 4, thus facilitating the removal of the internal microorganisms. When the biological sample is removed, a rubber cap 6 is installed inside the sealing cap 5. A sample delivery tube 7 is connected inside the rubber cap 6. The lower end of the sample delivery tube 7 is located inside the medicine bottle 4. An air bag 8 is connected to the side end of the sample delivery tube 7. A sample extraction tube 9 is connected to the side end of the air bag 8. The sample delivery tube 7 is connected to the sample extraction tube 9 through the air bag 8. The sample delivery tube 7, the sample extraction tube 9, and the air bag 8 are all made of transparent, sterile, and chemically resistant medical-grade silicone. They are all disposable. The inner diameter of the sample extraction tube 9 is small, so the air bag 8 can generate a greater negative pressure in the sample extraction tube 9.

[0026] The sample extraction tube 9 is connected to a sampling head 10 at its side end. The sampling head 10 is made of a flexible and elastic material and is shaped like a slender cone with a blunt rounded tip to avoid damage to the sampling site. The surface of the sampling head 10 is provided with tiny spiral textures to help better adsorb microorganisms during sampling. An operating rod 14 is inserted into the outer end of the sample extraction tube 9. Since the sample extraction tube 9 is a flexible tube, the position of the sampling head 10 can be easily adjusted by using the operating rod 14 to perform accurate sampling.

[0027] A protective cotton pad is installed inside the placement slot 3, and a push plate 15 is installed inside the storage box 1. The push plate 15 is located at the lower end of the placement slot 3, and the outer end of the push plate 15 is wrapped with a protective cotton pad to protect the medicine bottle 4. An electric telescopic cylinder 16 is connected to the lower end of the push plate 15, and a control button for the electric telescopic cylinder 16 is correspondingly installed on the upper end of the power supply block 11. The corresponding electric telescopic cylinder 16 can be operated by the control button, so that the medicine bottle 4 can be pushed out of the placement slot 3 by the push plate 15, making it easy to remove the medicine bottle 4. An elastic card 17 is installed on the upper end of the storage box 1. After the microbial sample is extracted, the sample delivery tube 7 is inserted into the elastic card 17 to seal the sample delivery tube 7, thereby preventing external bacteria from entering the medicine bottle 4.

[0028] In use, this invention involves injecting a specific microbial preservation solution into the medicine bottle 4 via a syringe. The power supply block 11 provides current to the heating wire 2, generating heat. A temperature sensor 13 detects the temperature around the placement slot 3, and the power of the heating wire 2 is adjusted via the current adjustment button 12 to maintain the temperature around the placement slot 3 at body temperature. The operating lever 14 moves the sampling head 10 to the sampling point. Then, the airbag 8 is pressed; as the airbag 8 recovers, a negative pressure is generated in the sample extraction tube 9, allowing the microbial sample to be drawn into the airbag 8 through the sampling head 10. The sample delivery tube 7 is then verticalized, allowing the microorganisms to fall into the medicine bottle 4. Finally, the sample delivery tube 7 is secured in the elastic card 17, sealing the sample delivery tube 7 and completing the sample collection.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
