[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0026] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0027] In the prior art, a bubble sensor is added to the dispensing equipment, and when the sample liquid flows into the bubble sensor, the content of the sample liquid can be detected. However, if the liquid level of the sample liquid at this moment is between the two bubble sensors, the sampling personnel still cannot accurately sense it, which will lead to the mismatch between the amount of sample liquid to be dispensed and the amount of sample liquid taken out, thereby causing a waste of sample liquid.

[0028] To solve the above problems, this embodiment provides a packaging device, see Figure 1 , including a liquid inlet tube 1, a liquid storage tube 2, a liquid outlet tube 3 and a pressure device 4. The liquid inlet tube 1 can absorb sample liquid; the liquid storage tube 2 can be selectively connected to the liquid inlet tube 1 for carrying the sample liquid; the liquid storage tube 2 is connected with a plurality of liquid outlet tubes 3, which can be selectively connected to the outside to output the sample liquid; the pressure device 4 is connected to the liquid storage tube 2 and is used to detect the pressure value in the liquid storage tube 2. The pressure device 4 detects the pressure value in the liquid storage tube 2 to accurately monitor the content of the sample liquid in the liquid storage tube 2, thereby reducing the waste of the sample liquid and improving the accuracy of the sample liquid packaging.

[0029] Specifically, the pressure device 4 is configured as a gas pressure gauge. When the sample liquid content in the liquid storage tube 2 gradually increases, the gas pressure in the liquid storage tube 2 will gradually increase, and the data reflected by the gas pressure gauge can accurately monitor the sample liquid content in the liquid storage tube 2.

[0030] Furthermore, a filter 5 is provided between the liquid storage tube 2 and the gas pressure gauge. The filter 5 can prevent the sample liquid from entering the gas pressure gauge, thereby damaging the gas pressure gauge, and since the liquid storage tube 2 is made of sterile material, the filter 5 can also prevent bacteria from entering the liquid storage tube 2 from the gas pressure gauge, thereby preventing the sample liquid from being contaminated. Since a certain amount of bacteria will be stored in the filter 5, the filter 5 needs to be replaced regularly.

[0031] Furthermore, a driving component is provided on the liquid inlet tube 1, and the driving component can drive the liquid inlet tube 1 to absorb the sample liquid and transport the sample liquid to the liquid storage tube 2. Specifically, the driving component is configured as a high-precision peristaltic pump 7. The high-precision peristaltic pump 7 is a precision pump based on the peristaltic principle. The roller of the high-precision peristaltic pump 7 rolls along the liquid inlet tube 1, squeezing and releasing the liquid inlet tube 1 in turn, thereby promoting the flow of the sample liquid, and can prevent the sample liquid from being contaminated while driving the sample liquid.

[0032] Furthermore, a bubble sensor 8 is provided on the liquid inlet pipe 1 to reflect the sample liquid entering the liquid storage pipe 2. In this embodiment, an exhaust solenoid valve 6 is provided between the filter 5 and the gas pressure gauge, and the exhaust solenoid valve 6 can be opened to exhaust the gas in the liquid storage pipe 2. The bubble sensor 8, the high-precision peristaltic pump 7 and the exhaust solenoid valve 6 need to be used in conjunction with each other in this embodiment, so that the air pressure value in the liquid storage pipe 2 is 0 kpa when no sample liquid enters, so as to ensure the accuracy of the gas pressure gauge in reflecting the sample liquid content in the liquid storage pipe 2.

[0033] Furthermore, a first pinch valve 11 is provided on the liquid inlet pipe 1 , and the first pinch valve 11 can be opened or closed to connect or block the liquid inlet pipe 1 and the liquid storage pipe 2 .

[0034] Furthermore, ten liquid outlet tubes 3 are evenly spaced along the flow direction of the sample liquid. All the liquid outlet tubes 3 are provided with second pinch valves 31, which can be opened or closed to connect or block the liquid outlet tube 3 and the outside. Specifically, the values ​​reflected by the gas pressure gauges along the flow direction of the sample liquid at the ten second pinch valves 31 are: 37.1kpa, 40.6kpa, 43.6kpa, 46.6kpa, 50.2kpa, 53.5kpa, 57.3kpa, 61.1kpa, 65.1kpa and 68kpa, respectively.

[0035] For example, when the packaging device in this embodiment is used, the first clamp valve 11 is first opened to connect the liquid inlet tube 1 with the liquid storage tube 2, and then the high-precision peristaltic pump 7 is opened to drive the sample liquid to flow from the liquid inlet tube 1 to the liquid storage tube 2. When the sample liquid flows to the bubble sensor 8, the high-precision peristaltic pump 7 is closed, and the exhaust solenoid valve 6 is opened to exhaust the gas in the liquid storage tube 2. At this time, the value reflected by the gas pressure gauge is 0kpa, and then the exhaust solenoid valve 6 is closed, and the high-precision peristaltic pump 7 is reopened. The sample liquid content in the liquid storage tube 2 is monitored by the gas pressure gauge. When the sample liquid content reaches the required value, the first clamp valve 11 and the high-precision peristaltic pump 7 are closed. At this time, corresponding to different sample liquid contents, the corresponding second clamp valve 31 is opened to realize the packaging of the sample liquid. The pressure value in the liquid storage tube 2 is detected by the gas pressure gauge to accurately monitor the content of the sample liquid in the liquid storage tube 2, thereby reducing the waste of the sample liquid and improving the accuracy of the sample liquid packaging.

[0036] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
