Description

Technical Field

[0001] The invention relates to the field of sampling tubes, in particular to a sample collection tube and a use method thereof. Background Art

[0002] Field collection of biological samples can provide valuable information to scientists, physicians, geneticists, epidemiologists, or the like.

[0003] For example, obtaining a fresh sample of a patient's blood, purulent secretions, or sputum can help a doctor or epidemiologist isolate or identify the pathogen causing the infection.

[0004] The samples are usually placed in a collection tube and transported to a designated location for testing. During testing, the samples need to be discharged into a test vessel or test tube. However, when discharging the samples, the existing sample collection tube does not pressurize the tube body in which the samples are placed, and the samples are only discharged naturally.

[0005] When discharged naturally, there are the following problems:

[0006] 1. When the sample is viscous, it cannot be discharged;

[0007] 2. The sample is discharged slowly. Summary of the invention

[0008] Purpose of the invention: To provide a sample collection tube and a method of using the same to solve the above problems existing in the prior art.

[0009] Technical solution: A sample collection tube, comprising:

[0010] A tube portion, the tube portion comprising a tube body for placing the sample, and an adapting inner cylinder disposed in the tube body;

[0011] A cover body is arranged on the top of the tube body, and an extrusion through hole is opened on the top of the cover body;

[0012] The piston part includes a piston cylinder and a piston body disposed in the piston cylinder;

[0013] The discharge part includes a one-way valve disposed at the bottom of the tube body and adapted to the inner cylinder body;

[0014] When the piston moves downward and the one-way valve moves upward, the sample in the tube is discharged quickly.

[0015] The present invention designs the piston part and the discharge part. When the sample is discharged, the external rod body is used to press against the piston body to change the internal pressure of the tube body. At the same time, the external container is used to press against the one-way valve to move upward, releasing the obstruction to the adapter inner cylinder, thereby completing the rapid discharge of the sample. Even if the sample is a viscous sample, it can be quickly discharged.

[0016] In a further embodiment, the outer side of the top of the tube body is provided with threads.

[0017] A thread groove matching the thread is provided inside the cover body.

[0018] In a further embodiment, the piston cylinder comprises:

[0019] A cylinder body, disposed in the tube body;

[0020] A limiting body, connected to the cylinder body and abutting against the top of the tube body and located between the cover body and the tube body;

[0021] The piston body is disposed in the cylinder body and is adapted to the cylinder body.

[0022] In a further embodiment, a filter cartridge is further provided in the tube body, and the filter cartridge is located below the tube body.

[0023] In a further embodiment, an adapter frame is further provided in the tube body, and the adapter frame is arranged between the adapter inner cylinder and the filter cylinder.

[0024] In a further embodiment, a bayonet is provided on the adapter frame.

[0025] In a further embodiment, the one-way valve includes a connecting buckle adapted to the bayonet, a valve body connected to the connecting buckle and located in the adapting inner cylinder, and a force-bearing portion arranged at the bottom of the valve body and outside the adapting inner cylinder.

[0026] In a further embodiment, a discharge port is formed in the valve body, and a discharge passage is communicated with the discharge port and extends to the outside of the valve body.

[0027] A method for using a sample collection tube, comprising:

[0028] Step 1: The force-bearing part is pressed to drive the valve body upward, and at this time, the discharge port contacts the sample stored inside the tube body, and the sample is filtered through the filter cartridge and discharged through the discharge port and the discharge channel;

[0029] This process can be completed by a vessel, where the vessel presses against the force-bearing part to discharge the sample into the vessel.

[0030] Step 2: When the sample is discharged, the external rod body is extended into the piston cylinder through the extrusion through hole, and the piston body is driven to descend in the piston cylinder, thereby accelerating the discharge speed of the sample.

[0031] This process can be completed by the external rod body, which drives the movement of the piston body and changes the pressure in the tube body, so that the sample can be discharged quickly, even if the sample is viscous.

[0032] Beneficial effect: The present invention discloses a sample collection tube and a method for using the same. The present invention designs a piston part and a discharge part. When the sample is discharged, the external rod body is used to press against the piston body to change the internal pressure of the tube body. At the same time, an external container is used to press against the one-way valve to move upward, thereby releasing the obstruction to the adapter inner cylinder body, thereby completing the rapid discharge of the sample. Even if the sample is a viscous sample, it can be quickly discharged. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] When the piston body 232C moves downward and the one-way valve 232G moves upward, the sample in the tube body 232A is quickly discharged.

[0047] The present invention designs the piston part and the discharge part. When the sample is discharged, the external rod body is used to press against the piston body 232C to change the internal pressure of the tube body 232A. At the same time, the external container is used to press against the one-way valve 232G to move upward, releasing the obstruction to the adapter inner cylinder 232A1, thereby completing the rapid discharge of the sample. Even if the sample is a viscous sample, it can be quickly discharged.

[0048] The top outer side of the tube body 232A is provided with threads.

[0059] A method for using a sample collection tube, comprising:

[0060] Step 1: The force-bearing portion 232G4 drives the valve body 232G2 to rise, and the discharge port 232G1 contacts the sample stored in the tube body 232A. The sample is filtered by the filter cartridge 232E and discharged through the discharge port 232G1 and the discharge channel 232G3;

[0061] This process can be completed through a container, where the container presses against the force-bearing portion 232G4 to discharge the sample into the container.

[0064] Working principle description:

[0065] The force-bearing portion 232G4 drives the valve body 232G2 to rise, and at this time, the discharge port 232G1 contacts the sample stored in the tube body 232A, and the sample is filtered by the filter cartridge 232E and discharged through the discharge port 232G1 and the discharge channel 232G3;

[0066] This process can be completed through a container, where the container presses against the force-bearing portion 232G4 to discharge the sample into the container.

[0067] When the sample is discharged, the external rod body extends into the piston cylinder 232D through the extrusion through hole, and drives the piston body 232C to descend in the piston cylinder 232D, thereby accelerating the discharge speed of the sample.

[0068] This process can be completed by the external rod body, which drives the piston body 232C to move and changes the pressure in the tube body 232A, so that the sample can be discharged quickly, even if the sample is viscous.
