Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a gynecological examination sample processing device. Background Technology

[0002] The main function of a gynecological examination sample processing device is to process and prepare samples collected from the female reproductive system for subsequent analysis, diagnosis, or research. These samples may include bodily secretions, cervical cells, endometrial tissue, etc., and are essential for assessing women's reproductive health, diagnosing gynecological diseases (such as infections, inflammation, cancer, etc.), and monitoring treatment effectiveness.

[0003] A gynecological examination sample processing device, such as the one disclosed in publication (announcement) number CN215458216U, includes a sampling cylinder. A negative pressure chamber is fixedly connected to the left side of the sampling cylinder, an air inlet pipe is connected to the right side of the negative pressure chamber, and an exhaust pipe is connected to the upper surface of the negative pressure chamber. A connecting rod is slidably connected to the left side of the negative pressure chamber, and the right end of the connecting rod extends into the interior of the negative pressure chamber and is fixedly connected to a piston. In this gynecological examination sample processing device, pulling the connecting rod causes the piston to slide inside the negative pressure chamber, simultaneously drawing air out of the sampling cylinder and expelling it through the exhaust pipe, creating a negative pressure inside the sampling cylinder. Simultaneously, through the inlet hose, external threaded sleeve, and sampling head, it can collect and sample the patient's internal secretions and fluids. This effectively solves the problem of small sample volume obtained using cotton swabs and the inability of cotton swabs to collect secretions, increasing the amount of secretions and fluids collected, improving sampling quality, and increasing the accuracy of sample testing.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that after the sampling is completed, since the sampling head is still partially open, external substances may enter through the opening, which may lead to sample contamination and affect the accuracy of the test results. At the same time, the placement of the device may cause sample backflow, which may affect the surrounding environment. Furthermore, the device has a complex structure and is designed for single use, which may increase the cost of use.

[0005] Therefore, a gynecological examination sample processing device is proposed to address the above-mentioned problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, such as insufficient sealing leading to sample contamination, this utility model provides a gynecological examination sample processing device.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a gynecological examination sample processing device, including a sampling tube, a first T-shaped tube fixedly installed on the bottom of one side of the sampling tube, a second T-shaped tube fixedly installed on the bottom of the sampling tube, a transmission rod movably installed in the inner cavity of the sampling tube, a piston block fixedly installed on the bottom of the transmission rod, a drainage tube fixedly installed on the bottom of the piston block, a plurality of upper drainage holes opened on the top of the surface of the drainage tube, a plurality of lower drainage holes opened on the bottom of the surface of the drainage tube, and a sealing block fixedly installed on the bottom of the drainage tube.

[0008] Preferably, a handle is fixedly installed on the top of the transmission rod, and a sampling dropper is movably installed inside the first T-shaped tube.

[0009] Preferably, a sealing sleeve is fixedly installed at one end of the sampling dropper, and the diameter of the sealing sleeve is adapted to the inner diameter of the large end of the first T-shaped tube.

[0010] Preferably, an airbag is fixedly installed at one end of the sealing sleeve.

[0011] Preferably, a transparent window is provided at the bottom of the sampling tube surface.

[0012] Preferably, the bottom of the sealing block is provided with rounded corners, and the outer diameter of the sealing block is adapted to the inner diameter of the large end of the second T-shaped tube.

[0013] Preferably, the first T-shaped tube is inclined at a 50-degree angle to the sampling tube, and the outer diameter of the drainage tube is matched with the inner diameter of the small end of the second T-shaped tube.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through the structural design of the sampling tube, the second T-shaped tube, the drainage tube, the upper drainage hole, the lower drainage hole, and the sealing block, and through the cooperation between the structures, achieves the function of increasing the sealing of the sample. This ensures that the sample moves only inside the device, reducing the chance of contact with the external environment and reducing the possibility of contamination. Furthermore, after sampling, the entire device is in a sealed state, further ensuring the purity of the sample. In summary, it solves the problem of sample contamination caused by insufficient sealing.

[0016] 2. The present invention, through the setting of the sealing sleeve, facilitates the matching with the large inner diameter of the first T-shaped tube, ensuring the sealing of the first T-shaped tube during the sampling process, so as to quickly form a negative pressure space inside the sampling tube, thereby meeting the conditions for driving the sample flow.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a gynecological examination sample processing device, including a sampling cylinder 1. A first T-shaped tube 2 is fixedly installed at the bottom of one side of the sampling cylinder 1, and a second T-shaped tube 3 is fixedly installed at the bottom of the sampling cylinder 1. A transmission rod 4 is movably installed in the inner cavity of the sampling cylinder 1. A piston block 5 is fixedly installed at the bottom of the transmission rod 4. A drainage tube 6 is fixedly installed at the bottom of the piston block 5. A plurality of upper drainage holes 7 are opened at the top of the surface of the drainage tube 6, and a plurality of lower drainage holes 8 are opened at the bottom of the surface of the drainage tube 6. A sealing block 9 is fixedly installed at the bottom of the drainage tube 6.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The sampling tube 1, the second T-shaped tube 3, the drainage tube 6, the upper drainage hole 7, the lower drainage hole 8, and the sealing block 9 are used to increase the sealing of the sample. This ensures that the sample moves only inside the device, reducing the chance of contact with the external environment and the possibility of contamination. Furthermore, the device is completely sealed after sampling, which further ensures the purity of the sample.

[0027] A handle 10 is fixedly installed on the top of the transmission rod 4, and a sampling dropper 11 is movably installed inside the first T-shaped tube 2.

[0028] Reference Figure 1 and Figure 4 The handle 10 allows medical staff to quickly drive the transmission rod 4 to work, while also providing a comfortable grip to improve their operating comfort.

[0029] A sealing sleeve 12 is fixedly installed at one end of the sampling dropper 11. The diameter of the sealing sleeve 12 is adapted to the inner diameter of the large end of the first T-shaped tube 2.

[0030] Reference Figure 4 The sealing sleeve 12 facilitates the fit with the large inner diameter of the first T-tube 2, ensuring the sealing of the first T-tube 2 during the sampling process, so that a negative pressure space can be quickly formed inside the sampling cylinder 1, thereby meeting the conditions for driving the sample flow.

[0031] An airbag 13 is fixedly installed at one end of the sealing sleeve 12.

[0032] Reference Figure 2 and Figure 4 The airbag 13 allows medical staff to create a negative pressure space inside the sampling dropper 11, thereby achieving the purpose of extracting a small amount of sample.

[0033] A transparent window 14 is provided at the bottom of the surface of the sampling tube 1.

[0034] Reference Figure 1 The transparent window 14 allows medical staff to quickly observe the sample volume, thereby ensuring the accuracy of the operation.

[0035] The bottom of the sealing block 9 is rounded, and the outer diameter of the sealing block 9 is adapted to the inner diameter of the large end of the second T-shaped tube 3.

[0036] Reference Figure 2 and Figure 4 The rounded corners at the bottom of the sealing block 9 reduce discomfort when the drainage tube 6 enters the patient's body, lowering the risk of irritation and damage to body tissues and thus protecting the patient's sensitive areas. At the same time, the matching of the outer diameter with the inner diameter of the large section of the second T-tube 3 ensures the overall sealing of the device after sampling, further reducing the possibility of the sample coming into contact with the external environment.

[0037] The first T-shaped tube 2 is inclined at a 50-degree angle to the sampling cylinder 1, and the outer diameter of the drainage tube 6 is matched with the inner diameter of the small end of the second T-shaped tube 3.

[0038] Reference Figure 2 and Figure 4 By tilting the first T-tube 2 at an angle, backflow of the sample inside the device is avoided, thus solving the problem that the sample may interfere with the surrounding environment.

[0039] Working principle: When using this device, the handle 10 drives the transmission rod 4 to move, which in turn drives the piston block 5 to move. The piston block 5 then drives the sampling tube into the patient's body. As the sampling tube enters the patient's body, the lower drainage hole 8 is open. When the sampling tube is embedded in the patient's body to a certain length, the pushing stops. Subsequently, the handle 10, in conjunction with the transmission rod 4, drives the sampling tube to pull back. The piston block 5 moves back synchronously with the transmission rod 4. As the piston block 5 moves, a negative pressure space is formed between the inner cavity of the sampling cylinder 1 and the piston block 5. This negative pressure space draws the suction through the upper drainage hole 7. The force is released through the drainage tube 6 to the lower drainage hole 8, which generates suction on the patient's body, drawing bodily secretions to the drainage tube 6. As the suction gradually releases, the secretions reach the upper drainage hole 7 through the drainage tube 6 and are released into the sampling tube 1 through the upper drainage hole 7. After the sampling tube is completely retrieved, the opening of the second T-shaped tube 3 is closed by the sealing block 9. At this time, the entire device is completely sealed. By squeezing the air bladder 13, a negative pressure space is formed inside the sampling dropper 11, and suction is generated at the opening of the sampling dropper 11 to take out a small amount of sample for testing.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
