[0035] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor does it necessarily refer to a particular embodiment in an exclusive sense. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0036] The blood gas analyzer, also known as blood gas biochemical analyzer, is a technical means for understanding the respiratory function and acid-base balance state of the human body by measuring the H+ concentration in the blood sample and the gas (mainly CO2, O2, etc.) dissolved in the blood. It can directly reflect the lung gas exchange function and acid-base balance state, and the specimen used is usually blood sample. The test card 20, also known as blood gas biochemical test card, can be used in cooperation with the blood gas analyzer to measure the PH value, hematocrit, ion concentration (K+, Na+, Cl-, Ca2+), glucose, lactic acid, or O2, CO2 partial pressure, etc. in the blood sample. Among them, the test card 20 can generally use electrochemical method or alternating current impedance method to complete the above parameter measurement.

[0037] As Figure 1 and Figure 2As shown, the test card 20 mainly comprises a main liquid channel 203 for calibration and liquid sample measurement and a reference cavity 204 for storing reference liquid (required for calibration). The test card 20 further comprises a main liquid channel valve 220 for controlling the opening and closing of the main liquid channel 203 and a reference valve 210 for controlling the opening and closing of the reference cavity 204. When the new test card 20 is installed into the blood gas analyzer, the blood gas analyzer closes the main liquid channel valve 220 and opens the reference valve 210, and the reference liquid flows into the reference cavity 204 through the liquid inlet hole 201 of the test card 20. After the reference liquid is drawn, when the blood gas analyzer performs normal calibration and sample measurement, the main liquid channel valve 220 is opened and the reference valve 210 is closed, and the reference liquid is sealed in the reference cavity 204, and the liquid sample can flow into the main liquid channel 203 from the liquid inlet hole 201 and flow out of the main liquid channel 20 from the liquid outlet hole 202 of the test card 20. When the liquid sample flows through the main liquid channel 20, blood clots in the liquid sample may accidentally occur, thereby blocking the main liquid channel 20 of the test card 20 or remaining in the main liquid channel 20, resulting in that the test card 20 cannot be normally used.

[0038] The embodiment of the present application provides a dredging piece 10 for dredging a medical test card 20, so that the test card 20 can be repeatedly used. Figures 3 to 5 As shown, the dredging piece 10 comprises a bracket 120 and a shell 110, and the shell 110 is provided with a containing cavity 1101, and the bracket 120 is located in the containing cavity 1101.

[0039] In some embodiments, the containing cavity 1101 is provided with a fixed opening 1104, and the bracket 120 can be installed in the containing cavity 1101 through the opening 1104.

[0040] In some embodiments, the containing cavity 1101 is provided with an openable and closable opening 1104, the bracket 120 can be installed in the containing cavity 1101 through the opening 1104 when the opening 1104 is opened, and the bracket 120 can be limited in the containing cavity 1101 when the opening 1104 is closed.

[0041] Optionally, the bracket 120 is used for fixing the test card 20, the bracket 120 is provided with a first connecting port 1301 and a second connecting port 1302 which are communicated, the second connecting port 1302 is used for communicating with the liquid inlet hole 201 or the liquid outlet hole 202 of the test card 20, and the first connecting port 1301 is used for connecting with a pressure source. Under the action of the pressure of the pressure source, the cleaning liquid can enter the test card 20, dredge and clean the blood clots and the like residues, thereby restoring the use of the test card 20, and improving the repeated utilization rate and working life of the test card 20.

[0042] Optionally, the pressure source can be a syringe or a liquid pump or other device that can convert mechanical energy into hydraulic energy. A liquid pump is a device that conveys or pressurizes liquid, and it can transfer liquid from one location to another by mechanical action. Liquid pumps are widely used in water treatment, chemical, petroleum, food, medicine and many other industries. Specifically, the pressure source can be a gear pump, a plunger pump, a vane pump or a screw pump, etc., wherein the gear pump compresses fluid by rotation of gears; the plunger pump compresses fluid by reciprocating motion of a plunger; the vane pump compresses fluid by rotating vanes; and the screw pump compresses fluid by rotation of a screw.

[0043] When the test card 20 needs to be unclogged, the test card 20 is placed in the support 120. There are at least the following optional ways to unclog the test card 20 in this application:

[0044] 1) The second interface 1302 of the support 120 communicates with the liquid inlet hole 201 of the test card 20, and the first interface 1301 of the support 120 interfaces with the pressure source, at which time the pressure source applies positive pressure to the test card 20.

[0045] Specifically, by manual or circuit control, the pressure source is driven to generate positive pressure, and under the positive pressure, the pressure source injects cleaning liquid into the liquid inlet hole 201 through the second interface 1302, and then the cleaning liquid enters the test card 20. The clogging point in the test card 20 is eventually unclogged under the pressure of the cleaning liquid. Optionally, during the process of unclogging the test card 20, the pressure change in the test card 20 can be detected to determine whether the test card 20 has been successfully unclogged. If it is not successful at one time, the pressure generated by the pressure source can be increased to unclog again.

[0046] 2) The second interface 1302 of the support 120 communicates with the liquid outlet hole 202 of the test card 20, and the first interface 1301 of the support 120 interfaces with the pressure source, at which time the pressure source applies negative pressure to the test card 20.

[0047] Specifically, under the action of the negative pressure applied by the pressure source, a negative pressure is formed in the support 120 and the test card 20, and under the drive of the negative pressure, the clogging point in the test card 20 is eventually unclogged under the negative pressure formed between the pressure source and the clogging point, and the blood clots in the clogging point are sucked out of the test card. Optionally, under the continued work of the pressure source, the liquid inlet hole 201 sucks in cleaning liquid to clean the unclogged test card. After the test card 20 is cleaned by the cleaning liquid, the cleaning liquid is sucked into the pressure source through the liquid outlet hole 202 and the first interface 1301.

[0048] In some embodiments, the liquid inlet hole 201 of the test card 20 can directly suck in cleaning liquid, or the liquid inlet hole 201 can also suck in cleaning liquid through other interfaces on the support 120 that communicate with the liquid inlet hole 201.

[0049] 3) The unclogging member 10 further comprises a pressure delivery pipe (not shown in the figure), the second interface 1302 of the support 120 is in communication with the liquid inlet hole 201 of the test card 20, and the first interface 1301 of the support 120 is indirectly connected with the pressure source through the pressure delivery pipe, at this time the pressure source gives the test card 20 a positive pressure.

[0050] Specifically, the pressure source injects the cleaning liquid into the support 120 through the pressure delivery pipe, and the cleaning liquid flows through the first interface 1301, the second interface 1302, the liquid inlet hole 201 and the liquid outlet hole 202 in turn under the positive pressure of the pressure source, so as to unclog and clean the test card 20. Further, the two ends of the pressure delivery pipe are sealingly connected with the support 120 and the pressure source respectively, so as to ensure that there is no pressure relief or cleaning liquid leakage at the connection during the pressure application process of the pressure source.

[0051] 4) The second interface 1302 of the support 120 is in communication with the liquid outlet hole 202 of the test card 20, and the first interface 1301 of the support 120 is indirectly connected with the pressure source through the pressure delivery pipe, at this time the pressure source gives the test card 20 a negative pressure through the pressure delivery pipe.

[0052] Specifically, the pressure source applies a negative pressure through the pressure delivery pipe, so that a negative pressure is formed in the support 120 and the test card 20, and under the driving of the negative pressure, the clogging point in the test card 20 is finally unblocked under the negative pressure formed between the pressure source and the clogging point, and the blood clots in the clogging point are sucked out of the test card. Optionally, under the continuous work of the pressure source, the liquid inlet hole 201 of the test card 20 sucks in the cleaning liquid, and after the test card 20 is unclogged and cleaned by the cleaning liquid, the cleaning liquid is sucked into the pressure source through the liquid outlet hole 202 and the first interface 1301.

[0053] Optionally, the pressure delivery pipe can constitute the unclogging member 10 alone, at this time the two ends of the pressure delivery pipe correspond to the first interface 1301 and the second interface 1302 respectively.

[0054] Optionally, for any one of the above-mentioned first and third unclogging modes, the support 120 or the test card 20 can be provided with a waste liquid chamber for collecting the waste liquid after the test card 20 is cleaned.

[0055] Specifically, when the second interface 1302 is in communication with the liquid inlet hole 201 and the first interface 1301 is connected with the pressure source, at this time the pressure source gives the test card 20 a positive pressure, and the cleaning liquid injected from the first interface 1301 of the pressure source can flow into the waste liquid chamber after unclogging and cleaning the main liquid channel 20 of the test card 20.

[0056] Optionally, for any of the above four unclogging modes, the support 120 is further provided with a third connecting port 1303 and a fourth connecting port 1304 in communication, one of the second connecting port 1302 and the fourth connecting port 1304 is in communication with the liquid inlet hole 201, and the other is in communication with the liquid outlet hole 202, the third connecting port 1303 is used to inject cleaning liquid when the fourth connecting port 1304 is in communication with the liquid inlet hole 201, or the third connecting port 1303 is used to discharge waste liquid when the fourth connecting port 1304 is in communication with the liquid outlet hole 202.

[0057] Specifically, when the second connecting port 1302 is in communication with the liquid inlet hole 201, the first connecting port 1301 is connected with the pressure source, the fourth connecting port 1304 is in communication with the liquid outlet hole 202, the waste liquid generated after the test card 20 is unclogged and cleaned can be discharged from the third connecting port 1303; when the second connecting port 1302 is in communication with the liquid outlet hole 202, the first connecting port 1301 is connected with the pressure source, the fourth connecting port 1304 is in communication with the liquid inlet hole 201, the cleaning liquid can be injected into the test card 20 from the third connecting port 1303.

[0058] It should be noted that, unless otherwise stated, the connection relationship between the second connecting port 1302, the fourth connecting port 1304, the liquid inlet hole 201, and the liquid outlet hole 202 will be described below with the first unclogging mode as an example. For other unclogging modes, those skilled in the art can analogize according to the first unclogging mode, and the present application will not be specifically described in detail.

[0059] Specifically, when the second connecting port 1302 is in communication with the liquid inlet hole 201, the first connecting port 1301 is connected with the pressure source, the pressure source can inject cleaning liquid into the first connecting port 1301, the waste liquid formed after the cleaning liquid flows through the main liquid channel 203 for unclogging and cleaning can be discharged from the third connecting port 1303. The cleaning liquid can flow in sequence along the first connecting port 1301, the second connecting port 1302, the liquid inlet hole 201, the main liquid channel 203, the liquid outlet hole 202, the fourth connecting port 1304, and the third connecting port 1303, and the flow process of the cleaning liquid can be repeated multiple times until the main liquid channel 203 is unclogged.

[0060] In some other embodiments, the cleaning liquid can also be injected from the third connecting port 1303 and flow out from the first connecting port 1301 for reverse flow cleaning.

[0061] In some embodiments, the support 120 can be made of hard materials such as plastic, resin, high polymer material, etc. For example, the support 120 can be made of acrylonitrile-butadiene-styrene plastic, polydimethylsiloxane, polycarbonate, polymethyl methacrylate, polystyrene, polypropylene, cyclic olefin copolymer, etc. and can be processed by injection molding, numerical control machine tool processing or 3D printing, etc.

[0062] In some embodiments, the material of the shell 110 can be similar to that of the bracket 120. The shell 110 can be made of hard materials such as plastic, resin, and polymer. For example, the shell 110 can be made of polypropylene, polyethylene, polycarbonate, and the like, and can be processed by injection molding, numerical control machine tool processing, or 3D printing.

[0063] Optionally, as shown in Figure 8 and Figure 9 The bracket 120 includes a first face 127 and a second face 128 arranged opposite to each other. The first face 127 is arranged close to the test card 20. The first interface 1301 and the third interface 1303 are located on the first face 127. The first face 127 is provided with a mounting area 121 for mounting the test card 20. The second interface 1302 and the fourth interface 1304 are located in the mounting area 121. The first interface 1301 and the third interface 1303 are located outside the mounting area 121. The liquid inlet hole 201 and the liquid outlet hole 202 of the test card 20 are often located on the side of the test card 20 away from the main liquid channel 203. Directly injecting cleaning liquid into the liquid inlet hole 201 can cause damage to the liquid inlet hole 201, and it is not easy to observe the dredging and cleaning condition of the main liquid channel 203. The first interface 1301 and the third interface 1303 of the present application are located on the side of the bracket 120 close to the test card 20. The first interface 1301, the third interface 1303, and the main liquid channel 203 are located on the same side of the bracket 120. This improves the reliability of the connection between the first interface 1301 and the pressure source, facilitates the injection of cleaning liquid, and facilitates the observation of the dredging and cleaning condition of the main liquid channel 203.

[0064] Further, the liquid inlet hole 201 and the liquid outlet hole 202 of the test card 20 are located on the side of the test card 20 facing the bracket 120. When the test card 20 is mounted in the mounting area 121, the second interface 1302 and the fourth interface 1304 are in communication with the liquid inlet hole 201 and the liquid outlet hole 202 respectively and are blocked by the test card 20. The first interface 1301 and the third interface 1303 are located outside the mounting area 121 of the first face 127, and can be avoided from being blocked by the test card 20.

[0065] In some embodiments, the first pair of interfaces 1301 and the third pair of interfaces 1303 of the bracket 120 can be located at the same end of the first face 127, and the liquid inlet hole 201 and the liquid outlet hole 202 of the test card 20 are generally located at two ends of the test card 20 respectively, and thus the second pair of interfaces 1302 and the fourth pair of interfaces 1304 can be located at two ends of the mounting area 121 respectively to be connected with the liquid inlet hole 201 and the liquid outlet hole 202. It should be noted that the distribution of the first pair of interfaces 1301, the second pair of interfaces 1302, the third pair of interfaces 1303 and the fourth pair of interfaces 1304 on the bracket 120 can adopt any feasible distribution in the case of adapting the test card 20. For example, the first pair of interfaces 1301 and the third pair of interfaces 1303 can also be located at two ends of the first face 127 respectively, and the second pair of interfaces 1302 and the fourth pair of interfaces 1304 can be located at the same end of the mounting area 121.

[0066] In some embodiments, the mounting area 121 can be a flat surface on the first face 127, and in other embodiments, the mounting area 121 is provided with a mounting groove 1202 for embedding the test card 20. Specifically, the mounting groove 1202 can be a recessed groove on the first face 127, or can be formed by a structure protruding from the first face 127, that is, the side wall of the mounting groove 1202 can be recessed into the first face 127 or protrude from the first face 127.

[0067] In some embodiments, a protruding portion 125 can be provided around the mounting groove 1202, and the protruding portion 125 is used to limit the test card 20.

[0068] In some embodiments, the shape of the mounting groove 1202 can be matched with the shape of the test card 20. Specifically, the shape of the test card 20 can be generally cuboid, and the shape of the mounting groove 1202 can also be generally cuboid. The protruding portion 125 is provided at four corners of the mounting groove 1202, and the protruding portion 125 can generally form a 90-degree corner and cooperate with the four corners around the test card 20 to limit the test card 20. In some embodiments, the shape of the test card 20 can also be cylindrical, circular truncated cone, polygonal prism, etc., and the shape of the mounting groove 1202 can be cylindrical, circular truncated cone, polygonal prism, etc. matched with the shape of the test card 20.

[0069] In some embodiments, a positioning post 126 may be provided in the mounting area 121. The positioning post 126 is used to position the test card 20. The test card 20 has positioning holes corresponding to the positioning post 126. When the test card 20 is installed in the mounting area 121, the positioning post 126 is inserted into the positioning hole, so that the second pair of interfaces 1302 and the fourth pair of interfaces 1304 can be aligned with the liquid inlet 201 and the liquid outlet 202. The number of positioning posts 126 can be one or more. Specifically, the number of positioning posts 126 can be two, and they are respectively positioned close to the second pair of interfaces 1302 and the fourth pair of interfaces 1304.

[0070] In some embodiments, such as Figure 9 As shown, the bracket 120 is provided with a first connecting pipe 123 and a second connecting pipe 124. The first connecting pipe 123 connects to the first pair of interfaces 1301 and the second pair of interfaces 1302, and the second connecting pipe 124 connects to the third pair of interfaces 1303 and the fourth pair of interfaces 1304. Specifically, the cleaning fluid can be injected into the test card 20 from the first pair of interfaces 1301, flow along the first pair of interfaces 1301, the first connecting pipe 123, the second pair of interfaces 1302, the inlet hole 201, the main liquid channel 203, the outlet hole 202, the fourth pair of interfaces 1304, the second connecting pipe 124, and the third pair of interfaces 1303, and be discharged from the third pair of interfaces 1303.
