[0050] The following detailed description will further describe the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION
[0051] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.
[0052] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application.
[0053] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined purpose, the present application will be described in detail below in conjunction with the drawings and preferred embodiments.
[0054] Please refer to Figure 1 The injector clamping device 100 provided by the embodiments of the present application includes a base 10, an elastic member 30, and a briquet 50. The elastic member 30 is arranged on the base 10, and the briquet 50 is arranged on the side of the elastic member 30 away from the base 10. The injector clamping device 100 is arranged between an injector and an injection pump. The base 10 is arranged on the injection pump. The elastic member 30 provides an elastic force to the briquet 50 in a direction away from the base 10, so that the briquet 50 abuts against the injector, thereby clamping the injector on the injection pump.
[0055] In an embodiment, the base 10 comprises an anti-skid surface 11 on the side away from the elastic member 30, which is used to contact the syringe pump. The anti-skid surface 11 can be coated with an anti-skid coating layer by applying a coating with a granular material, provided with anti-skid lines, embedded with anti-skid particles on the surface, sanded on the surface, attached with an anti-skid tape or pad, etc. to achieve the effect of anti-skid, thereby increasing the friction coefficient of the surface of the anti-skid surface 11, and further increasing the friction between the anti-skid surface 11 and the syringe pump. The elastic member 30 is also used to abut the anti-skid surface 11 against the syringe pump, so as to fix the relative position of the base 10 and the syringe pump. Specifically, the elastic member 30 is used to provide the base 10 with an elastic force in the direction of the syringe pump, so that the anti-skid surface 11 is fully abutted against the syringe pump, thereby achieving a relative fixation with the syringe pump under the action of friction. By providing the anti-skid surface 11, the relative position between the syringe pump and the base 10 can be fixed by friction, which is conducive to improving the installation convenience and flexibility of the syringe clamping device 100.
[0056] In another embodiment, the base 10 can also be fixed on the syringe pump. Specifically, the base 10 can be fixed on the syringe pump by screwing, or can be attached to the syringe pump by adhesive, or can be fixed on the syringe pump by buckling, which is not limited in the present application. By fixing the base 10 on the syringe pump, the syringe clamping device 100 can be prevented from falling off the syringe pump.
[0057] Please refer to Figure 2 , the base 10 further comprises a guide column 13, and the pressing block 50 is used to be sleeved on the guide column 13, and the guide column 13 is used to guide the movement of the pressing block 50. Specifically, the guide column 13 is on the side of the base 10 away from the anti-skid surface 11, and the guide column 13 extends in the direction away from the anti-skid surface 11, and the pressing block 50 is sleeved on the guide column 13, so as to move along the direction in which the guide column 13 extends. The elastic member 30 is arranged between the base 10 and the pressing block 50, and when the elastic member 30 generates an elastic force on the pressing block 50, the guide column 13 can guide the movement direction of the pressing block 50, thereby avoiding the pressing block 50 from being separated from the base 10.
[0058] In an embodiment, the guide column 13 is a threaded column screwed on the base 10, and the length of the guide column 13 can be adjusted by rotation, thereby adjusting the movable range of the pressing block 50, and further adapting to syringes and syringe pumps with different distances.
[0059] In the present embodiment, the elastic member 30 is specifically a spring structure, one end of the elastic member 30 is fixed on the base 10, and the other end is used to abut against the pressing block 50, thereby providing the pressing block 50 with an elastic force in the direction away from the base 10. In other embodiments, the elastic member 30 can also be other elastic structures, which are not limited in the present application.
[0060] In some embodiments, the guide column 13 can also be sleeved with elastic members 30, and the plurality of elastic members 30 simultaneously provide elastic force for the pressing block 50. The number and arrangement of the elastic members 30 are not limited in the present application, as long as the elastic members 30 can generate elastic force between the pressing block 50 and the base 10.
[0061] The side of the pressing block 50 away from the base 10 includes an engagement surface 51 which is concave towards the base 10, and the engagement surface 51 is used to abut against the syringe. Specifically, the engagement surface 51 is a developable surface with an arc-shaped cross section, and the radius of curvature of the engagement surface 51 is greater than or equal to the radius of curvature of any syringe, so that the engagement surface 51 can adapt to syringes of different sizes and can be in full contact with the surface of the syringe, thereby avoiding movement of the syringe relative to the pressing block 50 when abutting against the syringe.
[0062] In an embodiment, the engagement surface 51 is provided with a knurled structure 511, and the syringe includes knurls, and the knurled structure 511 is used to engage with the knurls on the syringe, so that when the pressing block 50 abuts against the syringe, the pressing block 50 and the syringe can be directly fixed by engaging with each other.
[0063] In another embodiment, referring to Figure 3 , the engagement surface 51 is provided with an anti-slip structure 513, and the anti-slip structure 513 is used to fix the relative position between the pressing block 50 and the syringe when the pressing block 50 abuts against the syringe. Specifically, the anti-slip structure 513 can be achieved by applying an anti-slip coating layer by applying a coating with a granular material, providing anti-slip lines, embedding anti-slip particles on the surface, sanding the surface, attaching an anti-slip adhesive tape or gasket, etc. By providing the anti-slip structure 513, the friction between the engagement surface 51 and the syringe can be increased by increasing the coefficient of friction, thereby fixing the relative position between the pressing block 50 and the syringe, and further avoiding sliding when the pressing block 50 abuts against the syringe. Moreover, by providing the anti-slip structure 513, the syringe clamping device 100 can adapt to syringes of various models, that is, when the syringe is not provided with knurls, the pressing block 50 can also fix the relative position with the syringe while abutting against the syringe.
[0064] Please refer to Figure 1 and Figure 2The base 10 is further provided with a first clamping part 15, and the pressing block 50 is further provided with a second clamping part 53. The first clamping part 15 and the second clamping part 53 form a clasp structure for clamping the pressing block 50 and the base 10. Specifically, in the embodiment, the first clamping part 15 is a clamping groove, and the second clamping part 53 is a clamping tongue. The second clamping part 53 can be clamped on the first clamping part 15, so as to clamp the pressing block 50 on the base 10. In other embodiments, the first clamping part 15 can also be a clamping tongue, and the second clamping part 53 can be a clamping groove. The first clamping part 15 and the second clamping part 53 can also be other clamping structures, which are not limited in the application.
[0065] In the embodiment, the number of the first clamping part 15 is two, and the first clamping part 15 is respectively located on the opposite sides of the base 10. The number of the second clamping part 53 is two, and the second clamping part 53 is respectively located on the opposite sides of the pressing block 50. Each first clamping part 15 corresponds to a second clamping part 53. In other embodiments, the number of the first clamping part 15 can also be three or more, and the number of the second clamping part 53 corresponds to the number of the first clamping part 15, which is not limited in the application.
[0066] The first clamping part 15 and the second clamping part 53 are used to buckle the pressing block 50 and the base 10 when the pressing block 50 is pressed towards the base 10. At this time, the elastic member 30 is in a compressed state. Specifically, the first clamping part 15 and the second clamping part 53 are used to fix the base 10 and the pressing block 50 when the syringe clamping device 100 does not act between the syringe and the injection pump, so as to avoid the pressing block 50 from falling off the base 10.
[0067] By setting the first clamping part 15 and the second clamping part 53, the pressing block 50 and the base 10 can be fixed. On the one hand, it is convenient to store the syringe clamping device 100. On the other hand, it is convenient to place the syringe clamping device 100 between the syringe and the injection pump. Since the pressing block 50 and the base 10 are in a clamped state, after the clamping state is released, the elastic member 30 releases the elastic force, so as to abut the base 10 to the injection pump and abut the pressing block 50 to the syringe, thereby realizing the fixation of the syringe and improving the convenience of installation.
[0068] The syringe clamping device 100 provided by the embodiment of the present application can use the elastic force to abut the pressing block 50 against the syringe, so that the syringe is pressed, and then the syringe is abutted against the syringe pump, so that the syringe is fixed, thereby avoiding loosening of the syringe relative to the syringe pump, and then ensuring the sealing between the syringe and the syringe pump. The engagement surface 51 of the pressing block 50 is provided with the knurl structure 511 or the anti-skid structure 513, so that the position between the pressing block 50 and the syringe is relatively fixed, the abutting effect on the syringe is ensured, and the syringe is prevented from moving relative to the pressing block 50. The first clamping part 15 and the second clamping part 53 are provided, so that the pressing block 50 and the base 10 are fixed, thereby preventing the pressing block 50 from being separated from the base 10 under the action of the elastic member 30, and facilitating installation or storage of the syringe clamping device.
[0069] Please refer to Figure 4 and Figure 5 The injection module 200 provided by the embodiment of the present application includes the syringe pump 210, the syringe 230 and the syringe clamping device 100 in the above embodiment. The syringe pump 210 is used to drive the syringe 230 to perform a pumping action. The syringe 230 is connected to the syringe pump, and the syringe clamping device 100 is arranged between the syringe 230 and the syringe pump 210.
[0070] Specifically, in the embodiment, the two ends of the syringe 230 are connected to the syringe pump 210. The syringe pump 210 includes a motor and a liquid injection part (not shown in the figure). The syringe 230 is a piston structure. One end of the syringe 230 is connected to the motor, so that the piston moves under the driving of the motor. The other end of the syringe 230 is inserted into the liquid injection part, so that the liquid is pumped in and out. When the syringe pump 210 drives the syringe 230 to move, the end of the syringe 230 connected to the liquid injection part may be loosened due to vibration. The syringe clamping device 100 is arranged at the end of the syringe 230 close to the liquid injection part, so that the syringe 230 is abutted against the liquid injection part, and the syringe 230 is clamped between the syringe pump 210, thereby avoiding loosening during operation.
[0071] The surface of the end of the syringe 230 close to the liquid injection part is provided with the knurl 231, which is engaged with the knurl structure 511 on the pressing block 50, so that the position between the pressing block 50 and the syringe 230 is relatively fixed, and the syringe clamping device 100 is prevented from falling off.
[0072] The injection module 200 provided by the embodiments of the present application can clamp the syringe 230 on the injection pump 210 by arranging the syringe clamping device 100 between the injection pump 210 and the syringe 230, so that loosening of the syringe 230 is avoided, and thus gas entering the injection module 200 or liquid leakage in the injection module 200 is avoided, which is beneficial to improve the sealing performance of the injection module 200, and thus the service life of the injection module 200 is improved, which is beneficial to reduce the replacement frequency of the injection module 200, and thus the cost is reduced.
[0073] The embodiments of the present application also provide a gene sequencer, which comprises the injection module 200 in the above embodiments, and the gene sequencer is used for sequencing work, and the injection module 200 is used for providing fluid for gene sequencing. By arranging the syringe clamping device 100, the syringe 230 can be clamped on the injection pump 210, so that loosening of the syringe 230 is avoided, and thus gas entering the injection module 200 or liquid leakage in the injection module 200 is avoided, which is beneficial to improve the sealing performance of the gene sequencer, reduce the replacement frequency of the injection module 200, and thus the service life of the gene sequencer is improved, which is beneficial to reduce the cost.
[0074] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as limitation to the present application, and any appropriate changes and modifications to the above embodiments within the scope of the spirit of the present application are within the scope of the present application.
