Please refer to Fig. 2 to Fig. 5, the present invention provides a sputum suction tube pressing controller 10, which includes an assembled tube body 101, an elastic body 102, a hollow valve body 103, a braking shaft body 105 and a cover body 104; the elastic body 102, the brake shaft body 105 and the hollow valve body 103 can be sequentially assembled into the assembly pipe body 101, and finally the cover body 104 is socketed on the assembly pipe body 101, the assembly steps are relatively simple, and there will be no The problem of directional confusion in assembly can effectively save man-hours.

Specific embodiments of the present invention will be described in detail below. Fig. 2 is a three-dimensional exploded view of the sputum suction tube pressing controller of the present invention; as shown in Fig. output pipe 101b, and an inner pipe 101c is concentrically arranged in the assembly pipe body 101, and the inner pipe 101c is communicated with the input pipe 101a and the output pipe 101b respectively; wherein, the output pipe 101b can also be connected with a vacuum suction machine (not shown in the figure) ), to provide a power source for pumping sputum, the output tube 101b can also be provided with a dustproof cover 106, and the inner bottom surface of the inner tube 101c is also protrudingly provided with a guide tube 101g, and the guide tube 101g is pierced through Brake shaft body 105 .

The elastic body 102 can be conical or cylindrical and arranged on the inner tube 101c, and one end of the elastic body 102 abuts against the inner bottom surface of the inner tube 101c; wherein, the elastic body 102 can be a metal spring or a rubber spring, etc., but elastic The shape and material of the body 102 are not limited here. In this specific embodiment, the elastic body 102 is a cylindrical metal spring. The body 102 can restore the hollow valve body 103 to its original position. In other words, the elastic body 102 provides elastic restoring force when the hollow valve body 103 is pressed down.

The side of the assembled tube body 101 away from the cover body 104 forms a sealed end 101h, as shown in FIG. It can effectively reduce the chance of medical personnel or patients being exposed to bacteria and viruses, and reduce the chance of infection. The side of the assembled pipe body 101 far away from the cover body 104 forms a retracted sealing end 101h, and the support plates (not labeled) on both sides not only have the function of strengthening the structure of the sealing end 101h, but also save production costs; in addition, the sealing end The outer edge of the base 101i presents a wavy arc-shaped design, which conforms to the ergonomic design and can also save the medical staff when operating the suction tube to press the controller 10. Make it easy for the thumb to exert force on the cover body 104 .

The hollow valve body 103 is movably arranged in the inner tube 101c, and the braking shaft body 105 is penetrated through the hollow valve body 103, so that one end of the braking shaft body 105 abuts against the other end of the elastic body 102; wherein, the cover The body 104 is sheathed on the assembly tube body 101 , and a positioning hole 104 a is formed on the top surface of the cover body 104 , so that the other end of the braking shaft 105 is engaged in the positioning hole 104 a. More specifically, in this specific embodiment, the brake shaft body 105 includes a brake head 105a, a brake body 105b and a brake seat 105c, the brake head 105a and the brake body 105b The outer wall is respectively provided with at least one first rib arm 105d and at least one second rib arm 105e; since the inner wall of the hollow valve body 103 is provided with at least one sliding groove 103d corresponding to the second rib arm 105e, and the top of the cover body 104 A positioning hole 104a corresponding to the first rib arm 105d is formed on the surface, so when the sputum suction tube pressing controller 10 of the present invention is to be assembled, as shown in FIG. 2 , the elastic body 102 can be placed in the inner tube body 101c Then, the brake shaft body 105 is slid on the chute 103d through its second rib arm 105e to be firmly positioned in the hollow valve body 103, and the hollow valve body 103 with the brake shaft body 105 is abutted against the The other end of the above-mentioned elastic body 102, and then the cover body 104 is sleeved on the assembly pipe body 101. At this time, the positioning card of the first rib arm 105d of the braking shaft body 105 is set in the positioning hole 104a; The joint between a rib arm 105d and the positioning hole 104a is filled with silicone oil for sealing and lubrication, and is sealed with a heat-sealing glue (not shown) to complete the assembly. The heat-sealing glue can be hydrogenated heavy naphthene Acid (Hydrotreated Heavy Naphthenic), hydrocarbon (Hydrocarbon), paraffin (Paraffin) or a mixture of at least two or more, but not limited thereto.

Since the first rib arm 105d and the second rib arm 105e of the brake shaft body 105 are respectively connected to the chute 103d of the hollow valve body 103 and the positioning hole 104a of the cover body 104, when the cover body 104 is pressed down and rotated, it can pass The brake shaft body 105 makes the hollow valve body 103 and the cover body 104 press down and rotate in the same direction synchronously, so it has directionality and can effectively prevent the possible slippage caused by filling silicone oil; in addition, the brake shaft body 105 One end abuts against the other end of the elastic body 102. In this specific embodiment, the brake seat body 105c is a disc-shaped structure (as shown in Figure 3), while the elastic body 102 is a cylindrical spring, so the brake seat body 105c and the elastic body 102 can have a larger contact area. Compared with the generally used conical spring, the sputum suction tube pressing controller 10 of the present invention can also effectively control the movement of the elastic body 102, and the force required for pressing Smaller and more labor-saving; moreover, since the cover body 104 is not fixed on the assembly tube body 101, when the sputum suction tube pressing controller 10 is discarded, it is only necessary to release the joint between the first rib arm 105d and the positioning hole 104a. The heat-sealing glue can be easily disassembled, and then the medical-grade biological waste treatment process can be carried out, so the possibility of residual bacteria and viruses caused by destructive disassembly spreading out of the sputum suction tube pressing controller 10 of the present invention can be greatly reduced.

The action mode of the sputum suction tube pressing controller 10 of the present invention will be described in detail below. Please refer to FIGS. 2 to 5 . The cross-sectional view of the hollow valve body of the sputum suction tube pressing controller of the present invention is at the second position, and Fig. 5 is a schematic diagram of the hollow valve body of the sputum suction tube pressing controller of the present invention at the first position; as shown in Fig. 3 and Fig. 4 As shown, the hollow valve body 103 is movably set between the first position and the second position; as shown in FIG. A plurality of vertical ribs 103b and a plurality of ribs 103c between the ribs 103b and the ribs 103b, more specifically, the ribs 103b and the ribs 103c are in the form of a rib 103b and a rib 103c The ribs 103b are connected to each other at intervals, and the ribs 103b have the function of strengthening the structure of the hollow valve body 103 and the effect of strengthening the sealing. In addition, the inner bottom surface of the assembled tube body 101 is provided with at least one arc-shaped limiting groove 101d, and the outer wall of the inner tube 101c is provided with at least one vertical positioning block 101e, 101f, and the cover body 104 is provided with a The engaging portion 104b, and the engaging portion 104b is provided with at least one limiting arm 104c corresponding to the limiting groove 101d and at least one positioning groove 104d, 104e corresponding to the positioning blocks 101e, 101f, and the outer wall of the cover body 104 is provided with There are first positioning grooves 104f and second positioning grooves 104g respectively corresponding to the input pipe 101a and the output pipe 101b; wherein, the cover body 104 has the first and second rotation directions, and the above-mentioned positioning blocks 101e, 101f and the positioning groove 104d , The number of 104e is not limited.
