Description

Technical Field

[0001] The present invention belongs to the technical field of reagent kits, and particularly relates to a Mycoplasma pneumoniae antigen detection kit. Background Art

[0002] A Mycoplasma pneumoniae antigen detection kit is a tool for rapidly detecting Mycoplasma pneumoniae infection.

[0003] For example, a Chinese patent with the publication number CN211122548U discloses a Mycoplasma pneumoniae antigen detection kit. The kit body is composed of a cotton swab cabinet, small and medium cardboards, a large cardboard, a detection card box, and a sliding groove. Since the items inside the kit body are classified and placed, and the opening directions and taking-out methods of different items are different, when the user takes out only one item, it can be quickly taken out, and the time for the user to search for items is also reduced, thus greatly improving the classification of the present invention.

[0004] Although this patent provides small and medium cardboards and a large cardboard for placing reagent tubes, because the inner diameters of the small and medium cardboards and the large cardboard are fixed, when the diameter of the reagent tube is slightly different from the inner diameters of the small and medium cardboards and the large cardboard, the reagent tube will continuously collide inside the small and medium cardboards and the large cardboard, generating noise and damaging the reagent tube. Summary of the Invention

[0005] The purpose of the present invention is to provide a Mycoplasma pneumoniae antigen detection kit to solve the problems raised in the above background art, including:

[0006] A test tube rack, on which a number of first slots are provided for placing reagent tubes;

[0007] A kit body for accommodating the test tube rack;

[0008] A pressurizing assembly provided inside the test tube rack, which can complete the extrusion and fixation of the reagent tube by pressurizing the gas.

[0009] Preferably, a number of second slots are provided inside the test tube rack, the number of second slots are respectively communicated with the number of first slots, a number of piston rods are respectively provided inside the number of second slots, a number of air channels are provided inside the test tube rack, the number of air channels are respectively communicated with the number of second slots, an internal thread channel is provided on the test tube rack, the number of air channels are communicated with the internal thread channel, the number of air channels are arranged at positions far from the number of piston rods, and the number of piston rods are arranged at positions close to the number of first slots.

[0010] Preferably, the pressurizing assembly includes:

[0011] An external thread column, which is threadedly connected with the internal thread channel.

[0012] Preferably, a plurality of third grooves are formed in the outer wall of the external thread column.

[0013] Preferably, a first wire body is fixedly connected between the external thread column and the test tube rack.

[0014] Preferably, a first channel is formed through the external thread column, and the first channel can communicate the second groove, the air duct, the internal thread channel and the outside. A threaded rod is threadedly connected inside the first channel.

[0015] Preferably, a plurality of fourth grooves are formed in the outer wall of the threaded rod.

[0016] Preferably, a second wire body is fixedly connected between the threaded rod and the external thread column.

[0017] Preferably, an elastic member is fixedly connected to the piston rod. The elastic member is fixed to the second groove, and the elastic member can pull the piston rod into the second groove by its own elastic force. The air duct is adjacent to the elastic member.

[0018] Preferably, the elastic member is a tension spring.

[0019] In this application, by rotating the external thread column, the external thread column enters the internal thread channel. The gas inside the internal thread channel is compressed, and the air pressure is applied to the surface of the piston rod through the air duct and the second groove in sequence. At this time, the piston rod is pushed out of the second groove and enters the first groove and contacts the reagent tube at the same time. As the air pressure continues to increase, the air pressure applied to the piston rod causes the piston rod to complete the extrusion and fixation of the reagent tube, preventing the reagent tube from colliding in the first groove, avoiding noise, and reducing the damage to the reagent tube caused by collision.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0029] In order to solve the problem that when the diameter of the reagent tube is slightly different from the diameters inside the small and medium-sized clamping plates and the large clamping plate, the reagent tube will continuously collide inside the small and medium-sized clamping plates and the large clamping plate, generating noise and damaging the reagent tube, this embodiment provides a Mycoplasma pneumoniae antigen detection kit, as Figure 1 - Figure 2 shown, including: a test tube rack 200 for placing Mycoplasma pneumoniae antigen detection reagent tubes, a cartridge body 100 for accommodating the test tube rack 200, and a pressurizing assembly 300 for fixing the Mycoplasma pneumoniae antigen detection reagent tubes (Mycoplasma pneumoniae antigen detection reagent tubes are hereinafter collectively referred to as reagent tubes).

[0030] As Figure 4 shown, the test tube rack 200 is square. Three first grooves 210 are formed on the top surface of the test tube rack 200. The first grooves 210 are cylindrical. The three first grooves 210 are used for placing reagent tubes. Three second grooves 220 are formed inside the test tube rack 200. The second grooves 220 are cylindrical. The three second grooves 220 are respectively communicated with the three first grooves 210. Three air passages 230 are formed inside the test tube rack 200. The air passages 230 are cylindrical. The three air passages 230 are respectively communicated with the three second grooves 220. An internal thread channel 240 is formed on the top surface of the test tube rack 200. The internal thread channel 240 is cylindrical, and a thread groove is formed on the inner wall. The bottoms of the three air passages 230 are communicated with the internal thread channel 240.

[0031] As Figure 1 shown, the cartridge body 100 is square. The cartridge body 100 is used for accommodating the test tube rack 200.

[0032] As Figure 4 shown, the pressurizing assembly 300 is arranged inside the test tube rack 200. The pressurizing assembly 300 can complete the extrusion and fixation of the reagent tube by pressurizing the gas. Specifically, as Figure 6As shown, three piston rods 500 are respectively arranged inside the three second grooves 220. The piston rods 500 are preferably made of rubber. The three air channels 230 are arranged at positions far from the three piston rods 500, and the three piston rods 500 are arranged at positions close to the three first grooves 210, as Figure 5 As shown, the pressing assembly 300 includes an external thread column 310. The external thread column 310 is cylindrical, and its outer wall is provided with threads. The external thread column 310 is threadedly connected to the internal thread channel 240. When it is necessary to squeeze and fix the reagent tube, first insert the reagent tube into the first groove 210, and then rotate the external thread column 310, gradually making the external thread column 310 enter the internal thread channel 240. As the external thread column 310 goes deeper, the gas inside the internal thread channel 240 is squeezed, and the air pressure is applied to the surface of the piston rod 500 through the air channel 230 and the second groove 220 in sequence. At this time, the piston rod 500 is pushed out of the second groove 220 and enters the first groove 210 and contacts the reagent tube at the same time. As the air pressure continues to increase, the air pressure applied to the piston rod 500 causes the piston rod 500 to complete the squeezing and fixing of the reagent tube, preventing the reagent tube from colliding inside the first groove 210, avoiding noise, and reducing the damage caused by the collision of the reagent tube.

[0033] Among them, reverse-rotating the external thread column 310 to reduce the air pressure can complete the release of the squeezing of the reagent tube.

[0034] In this solution, the further effect is that since the second groove 220, the air channel 230, and the internal thread channel 240 are connected and communicated, the air pressures received by the three piston rods 500 are the same, and the squeezing forces generated on the reagent tube are the same. Other effects are that multiple reagent tubes can be squeezed and fixed simultaneously without multiple operations.

[0035] In order to make the rotation of the external thread column 310 more stable, in a further solution, as Figure 5 As shown, a number of third grooves 311 are provided on the outer wall of the external thread column 310. The third grooves 311 increase the contact area with the hand, increase the friction, reduce the sliding generated when the hand rotates the external thread column 310, and improve the stability.

[0036] In order to prevent the external thread column 310 from falling off and being lost, in a further solution, as Figure 5 As shown, a first wire body 320 is fixedly connected between the external thread column 310 and the test tube rack 200. The first wire body 320 is made of a flexible material, which can cooperate with the rotation of the external thread column 310 and prevent the external thread column 310 from falling off and being lost.

[0037] In order to more quickly reduce the air pressure received by the piston rod 500, in a further solution, as Figure 5As shown, the external threaded column 310 is provided with a first channel 312, which is in the shape of a round rod. The first channel 312 can connect the second groove 220, the air channel 230, the internal threaded channel 240 with the outside world. The internal thread of the first channel 312 is connected with a threaded rod 330. By rotating the threaded rod 330 to open the first channel 312, the air pressure in the first groove 210, the second groove 220, the air channel 230, and the internal threaded channel 240 can be balanced. The piston rod 500 loses air pressure, and the release of the reagent tube is completed immediately.

[0038] In order to make the rotation of the threaded rod 330 more stable, in a further solution, as Figure 5 As shown, the outer wall of the threaded rod 330 is provided with a plurality of fourth grooves 331 , which increase the contact area with the hand, increase friction, reduce sliding when the hand rotates the threaded rod 330 , and improve stability.

[0039] In order to prevent the threaded rod 330 from falling off and being lost, in a further solution, as Figure 5 As shown, a second wire body 340 is fixedly connected between the threaded rod 330 and the external threaded column 310. The second wire body 340 is made of a flexible material and can cooperate with the rotation of the threaded rod 330 and prevent the threaded rod 330 from falling off and being lost.

[0040] In order to prevent the piston rod 500 from remaining in the first groove 210 and hindering the subsequent placement of the reagent tube after the air pressure is released, a further solution is provided. Figure 4 As shown, the piston rod 500 is fixedly connected to an elastic member 400, which is preferably a tension spring. The elastic member 400 is fixed to the second groove 220. The elastic member 400 can pull the piston rod 500 into the second groove 220 through its own elastic force, thereby facilitating the subsequent placement of the reagent tube into the first groove 210. The airway 230 and the elastic member 400 are adjacent.

[0041] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
