Description

Technical Field

[0001] This utility model belongs to the field of medical logistics equipment technology, specifically relating to a specimen tube descender and a specimen tube receiving device. Background Technology

[0002] In modern large hospitals, pneumatic tubing systems have become a core infrastructure for transporting laboratory specimens such as blood, urine, and tissue fluid to improve diagnostic efficiency and optimize the allocation of medical resources. Specimen tubes are transported at high speed within the pneumatic tubing, undergoing acceleration, turning, and deceleration from the specimen delivery device to the receiving device. At the receiving device, the specimen tube falls at a high speed, resulting in a severe impact. This impact can easily cause the specimen tube cap to detach or even the tube to rupture, leading to specimen leakage, cross-contamination, and contamination risks within the pneumatic tubing, as well as high cleaning and disinfection costs. Utility Model Content

[0003] The purpose of this invention is to provide a specimen tube decelerator and a specimen tube receiving device to buffer the specimen tube and reduce the impact on the specimen tube.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A specimen tube descent device, comprising: Vacuum generator; Gas connector, one end of which is connected to the vacuum generator, and the other end of which is used to connect to the gas source; The core tube is connected at one end to one end of the vacuum generator. The first connector connects to the other end of the core tube and is used to connect to the pneumatic pipe. The second connector connects to the other end of the vacuum generator.

[0005] Furthermore, the gas connector is equipped with a throttle valve for adjusting the gas flow rate and / or flow volume.

[0006] Furthermore, the core tube has a hollow structure.

[0007] Furthermore, the outer wall of the core tube is wrapped with a filter element.

[0008] Furthermore, the first connector is connected to a first connector lock nut, which is used to connect to a pneumatic pipeline.

[0009] Furthermore, a sensor for monitoring the specimen tube is provided at one end of the core tube.

[0010] Furthermore, the sensor is configured as a grating sensor.

[0011] Furthermore, the second connector is connected to a second connector lock nut.

[0012] Furthermore, a specimen tube receiving device includes the aforementioned specimen tube line decelerator.

[0013] Compared with the prior art, this utility model has the following advantages: In summary, this utility model describes a specimen tube decelerator applied to a specimen tube receiving device. This device creates a buffer environment, causing the high-speed specimen tube moving within the pneumatic pipeline to gradually decrease to a lower speed. This buffering reduces the impact on the specimen tube, effectively protecting its integrity. The device also effectively purifies the gas discharged from the pneumatic pipeline, intercepting any pathogenic microorganisms, aerosols, or dust that may be present, preventing pollution of the external environment. Furthermore, the addition of sensors allows for real-time monitoring of specimen tube passage and controls the throttle valve to quickly create the buffer environment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1 to 3 As shown, a specimen tube decelerator includes a vacuum generator 1, a gas connector 2, a core tube 3, a first connector 4, and a second connector 5.

[0019] One end of gas connector 2 is connected to vacuum generator 1, and the other end of gas connector 2 is used to connect to a gas source. One end of core tube 3 is connected to one end of vacuum generator 1, and the other end of core tube 3 is connected to first connector 4. First connector 4 is threadedly connected to first connector lock nut 6, which is used to connect to the pneumatic pipeline. Core tube 3 has a hollow structure, and the outer wall of core tube 3 is wrapped with filter element 8, which is used to purify the air in the pneumatic pipeline. The polluted gas generated by the pneumatic pipeline during the transport of specimen tubes is purified by filter element 8 and discharged into the atmosphere, intercepting any pathogenic microorganisms, aerosols, or dust that may be present, preventing them from polluting the external environment. The other end of vacuum generator 1 is connected to one end of second connector 5, and the other end of second connector 5 is threadedly connected to second connector lock nut 7, which can be connected to downstream equipment, such as a receiving box for receiving specimen tubes. When gas flows from the gas source into vacuum generator 1 through gas connector 2, the gas flows from one end of vacuum generator 1 to core tube 3. Vacuum generator 1 is a component already available in the prior art, enabling unidirectional gas flow from gas connector 2 to one end of vacuum generator 1. At this time, a vacuum zone is generated inside vacuum generator 1 and the second connector 5. When the specimen tube moves to the position of vacuum generator 1 and the second connector 5, a pressure difference is generated between atmospheric pressure and the vacuum zone, forming a buffering force opposite to the direction of specimen tube movement, thereby gradually reducing the specimen tube speed from high to low. The compressed gas flowing from vacuum generator 1 to core tube 3 is also purified by filter element 8 and discharged into the atmosphere. A throttle valve 9 is installed on gas connector 2 to regulate the flow rate and / or flow rate of gas entering vacuum generator 1. The higher the flow rate and / or flow rate, the more significant the buffering and deceleration effect of the specimen tube. This allows the device to flexibly adapt to specimen tubes of different weights and initial speeds, achieving customized deceleration effects and improving the applicability of the equipment.

[0020] In addition, a sensor 10 for monitoring the specimen tube is installed between the core tube 3 and the first connector 4. The sensor 10 is a grating sensor capable of detecting whether a specimen tube has entered the core tube 3. The controller is connected to the sensor 10 and the throttle valve 9 via signal cables. When the sensor 10 detects a specimen tube entering the core tube 3, it sends a signal to the controller, which then controls the throttle valve 9 to operate. The throttle valve 9 adjusts the flow rate and / or volume of gas entering the vacuum generator 1. The gas enters the vacuum generator 1, and then flows to the core tube 3 for purification before being discharged into the atmosphere. A vacuum is generated in the vacuum generator 1 and the second connector 5, providing a buffering force to the specimen tube and reducing the impact on it, effectively protecting the integrity of the specimen tube. The sensor 10 only allows gas to enter the vacuum generator 1 when it detects a specimen tube entering the core tube 3. After the gas supply has a slowing effect, it shuts off the gas supply to the vacuum generator 1 and turns it back on when the next specimen tube is detected, thus reducing gas consumption.
