Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a test tube vacuum device. Background Technology

[0002] Currently, after medical test tubes are sealed, the air inside is under positive pressure. During transportation, the caps are prone to detaching. This not only seriously affects the safety and integrity of the samples inside the test tubes but also brings numerous inconveniences and risks to the medical process. When the cap detaches during transport, external dust, microorganisms, and other impurities can easily enter and contaminate the sample, altering key indicators such as the sample's chemical composition and biological activity. This can lead to inaccurate test results based on the sample, potentially misleading doctors in diagnosing patients and delaying optimal treatment. Furthermore, detached caps can waste medical resources, as contaminated samples usually need to be recollected, undoubtedly increasing patient suffering and medical costs.

[0003] In the existing technology, a needle is inserted into the test tube manually, and then a vacuum pump is used to remove the air inside the test tube. The vacuum negative pressure adsorption method is used to ensure the stability and reliability of the test tube cap during transportation.

[0004] However, in the existing technology, only one test tube can be processed at a time, resulting in low vacuum suction efficiency and high labor intensity. Utility Model Content

[0005] The purpose of this invention is to provide a test tube vacuum device, which aims to solve the technical problem that the existing technology can only process one test tube at a time, resulting in low vacuum suction efficiency and high labor intensity.

Detailed Implementation

[0018] Please see Figures 1 to 4This utility model provides a test tube vacuum device, including a frame, a test tube rack, a cylinder 101, a gas distribution chamber 102, a syringe 103, a solenoid valve 104, a pressure gauge 105, a time relay 106, a pedal switch 107, an air pump 108, a first limit switch 109, and a second limit switch 110. The cylinder 101 is fixedly connected to the frame and located at the upper end of the frame. The output end of the cylinder 101 passes through the frame and is fixedly connected to the gas distribution chamber 102. Multiple sets of syringes 103 are provided, each set communicating with the gas distribution chamber 102 and located at the lower end of the chamber. The test tube rack is slidably connected to the frame and located at the upper end of the frame. The pressure gauge 105 is fixedly connected to the frame and located at the upper end of the frame. The time relay 106 is fixedly connected to the frame and located on one side of the frame. The solenoid valve 104 is fixedly connected to the frame and located on one side of the frame. The pedal switch 107 is electrically connected to the time relay 106. The input end of the air pump 108 is connected to the output end of the pressure gauge 105. The input end of the pressure gauge 105 is connected to multiple sets of needle tubes 103 through the gas diversion chamber 102. The first limit switch 109 is fixedly connected to the test tube rack and located on one side of the test tube rack. The second limit switch 110 is fixedly connected to the gas diversion chamber 102 and located at the lower end of the gas diversion chamber 102.

[0019] In this embodiment, during use, test tubes are placed one by one inside the test tube rack. Then, the test tube rack is pushed into the machine frame. The test tube vacuum device is activated by stepping on the pedal switch 107 to perform vacuuming of the test tubes. During operation, the cylinder 101 pushes the gas distribution chamber 102 downwards. Then, each set of needles 103 is inserted into each set of test tubes. The air pump 108 is activated to remove excess air from each set of test tubes, creating a vacuum negative pressure inside each set. After vacuuming is complete, the cylinder 101 is retracted, resetting the gas distribution chamber 102 and the needles 103. Finally, the test tube rack is pulled out. After the test tube has been vacuumed, it is removed. The first limit switch 109 is installed inside the test tube rack to sense whether the test tube rack has moved below the syringe 103. The time relay 106 is connected in series with the first limit switch 109 to control the solenoid valve 104. The solenoid valve 104 controls the extension and retraction of the cylinder 101. The second limit switch 110 is installed on the back of the gas diversion chamber 102. When the gas diversion chamber 102 contacts the second limit switch 110, it triggers the second limit switch 110 to close. The second limit switch 110 controls the air pump 108 to run, and the air pump 108 draws air out of the test tube.

[0020] Furthermore, the test tube vacuum device also includes a guide plate 111 and a guide ring 112. The guide plate 111 is fixedly connected to the frame and located inside the frame. The guide ring 112 is in multiple sets, and each set of guide rings 112 is fixedly connected to the guide plate 111 and is respectively embedded inside the guide plate 111.

[0021] In this embodiment, the guide plate 111 is installed inside the frame. The guide plate 111 is used to guide the needle tube 103 and improve its stability when puncturing the test tube cap. At the same time, the guide ring 112 can reduce the hard contact between the needle tube 103 and the guide plate 111 when the needle tube 103 moves, thereby protecting the needle tube 103.

[0022] Furthermore, the frame includes a base plate 113, a frame body 114, and slide rails 115. The frame body 114 is fixedly connected to the base plate 113 and is located at the upper end of the frame body 114. There are two sets of slide rails 115, and the two sets of slide rails 115 are fixedly connected to the base plate 113 respectively and are located at the upper end of the base plate 113 respectively.

[0023] In this embodiment, the base plate 113 supports the frame 114, which is used to install and fix the cylinder 101. Meanwhile, the slide rail 115 is placed on the upper end of the base plate 113 to move the test tube rack horizontally, thereby limiting the movement of the test tube rack and ensuring that the test tube rack can be moved to a suitable position when vacuuming.

[0024] Furthermore, the test tube rack includes a test tube compartment 116, a support plate 117, and sliders 118. There are multiple sets of sliders 118. Each set of sliders 118 is fixedly connected to the support plate 117 and located at the lower end of the support plate 117. Each set of sliders 118 is adapted to the frame. The test tube compartment 116 is fixedly connected to the support plate 117 and located at the upper end of the support plate 117.

[0025] In this embodiment, the support plate 117 supports and fixes the branch tube chamber, while multiple sets of sliders 118 are placed at the lower end of the support plate 117. The sliders 118 are adapted to the slide rail 115, and under the action of the multiple sets of sliders 118, the support plate 117 and the test tube chamber 116 can slide horizontally on the slide rail 115.

[0026] Furthermore, the test tube rack also includes a handle 119, which is fixedly connected to the support plate 117 and located on one side of the support plate 117.

[0027] In this embodiment, the handle 119 facilitates the stretching of the test tube rack, and the handle 119 can improve the user's convenience and hand grip comfort during operation.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model.
