DETAILED DESCRIPTION
[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:
[0032] See also Figure 1-7 As shown, the utility model is a medical device for microbial sampling, comprising a flapping box 1 with an upper opening, an electric telescopic push rod 2, a flapping plate 3, a flapping drive head 4, a pressure rod 5, and a pressure head 6. The electric telescopic push rod 2, the flapping plate 3, and the flapping drive head 4 together constitute a reciprocating extrusion and flapping execution part.
[0033] The flapping box 1 is a rectangular box. A partition 11 is fixed between opposing inner walls of the flapping box 1, dividing the flapping box 1 into a flapping compartment 12 and an equipment compartment 13. A sealing plate 14 is fixed to the upper opening of the flapping compartment 12, facing away from the equipment compartment 13. The equipment compartment 13 is hingedly mounted with a door 15. A knob-operated speed regulator 110 is mounted on the door 15, which is used to adjust the speed of the motor in the electric telescopic push rod 2.
[0034] A linear guide tube 16, which engages with the flapping drive head 4, is vertically fixed to the partition 11. The telescopic end of the electric telescopic push rod 2 abuts one end of the flapping drive head 4, while the other end of the flapping drive head 4 is in rolling connection with the flapping plate 3. The flapping drive head 4 includes a square post 41 that engages with the linear guide tube 16. A small wheel 42 is rotatably mounted on one end of the square post 41. The small wheel 42 is in rolling connection with the flapping plate 3 to reduce friction when the flapping plate 3 is rotated, thereby improving the durability of the flapping device.
[0035] The flapping plate 3 is rotatably mounted on the bottom of the flapping chamber 12 by two cylindrical seats 17. The flapping chamber 12 is fixed with a rubber plate 18 away from the inner wall of the equipment chamber 13. The bottom surface of the equipment chamber 13 is fixed with a motor mounting seat 19 for installing the electric telescopic push rod 2.
[0036] Axis 111, symmetrically fixed to the two side walls of the flapping housing 1 at the equipment compartment 13, are pivotally coupled to the pressure rod 5. A torsion spring 7 is sleeved onto the stub shaft 111, one end of which is plugged into the flapping housing 1, while the other end is plugged into the pressure rod 5. The pressure head 6 is pivotally mounted on the end of the pressure rod 5, facilitating parallel contact of the lower end of the pressure head 6 against the closed plate 14, resulting in a large ballast area and stable compression and positioning.
[0037] To ensure the flapping plate 3 returns quickly to its original position, a tension spring 8 is installed between the flapping plate 3 and the partition 11. Two first rings 31 are fixedly mounted on the side of the flapping plate 3 adjacent to the partition 11, hooked to one end of the tension spring 8. Two second rings 115 are fixedly mounted on the side of the partition 11, hooked to the other end of the tension spring 8.
[0038] Wherein for the convenience of controlling the time of beating, the warehouse door 15 is also equipped with a knob timer 116 to control the power-on time of the electric telescopic push rod 2. The knob timer 116 and the knob speed regulator 110 are used simultaneously and can adjust the beating time after adjusting the beating frequency.
[0039] The pressure rod 5 comprises two parallel rectangular rods 51. One end of the two rectangular rods 51 is connected to form a single body by a handlebar 52, which has an upwardly arched semicircular arc portion in the middle. A symmetrical first rotation hole 53 is defined at one end of the two rectangular rods 51. The other ends of the two rectangular rods 51 have symmetrical second rotation holes 54. The pressure rod 5 exerts a downward torsional force under the action of two torsion springs 7, pressing the pressure head 6 against the closed plate 14 to clamp and secure the object being tapped.
[0040] Among them, a rubber clip strip 113 is clamped on the closed flat plate 14. A row of first anti-slip grooves 114 are provided on the upper surface of the rubber clip strip 113. The pressure head 6 includes a rectangular pressure plate 61. In order to ensure tightness during clamping, a rubber pressure plate 62 is fixed on the lower surface of the rectangular pressure plate 61. A row of second anti-slip grooves 63 are provided on the lower surface of the rubber pressure plate 62. The design of the rubber clip strip 113 on the closed flat plate 14 and the anti-slip grooves 63 on the pressure head 6 increases the stability and tightness during clamping, prevents gas and liquid leakage, and ensures safe operation. An ear plate 64 is vertically fixed to the upper surface of each end of the rectangular pressure plate 61. The ear plate 64 is fixed on the side with a pin shaft rod 65 that rotates with the first rotating hole 53.
[0041] When sampling microorganisms from flexible non-metallic medical devices such as medical masks, Band-Aids, gauze bandages, and medical tape, one of these medical devices is cut into pieces and placed in a sterile medical plastic bag, into which 200 ml of sterile saline is added. The upper pressure rod 5 is placed into the flapping chamber 12, with the open end of the medical plastic bag resting on the rubber clip 113. The pressure rod 5 is then lowered, and the medical plastic bag is clamped between the rubber clip 113 and the rubber pressure plate 62. The electric telescopic push rod 2 is activated to reciprocate and push the flapping drive head 4 against the flapping plate 3. As the flapping plate 3 swings, the liquid in the medical plastic bag surges upward, flushing bacteria from the medical device debris into the sterile saline. After reciprocating flapping, a saline mixture containing the microorganisms from the medical device is obtained. After the flapping is complete, the pressure rod 5 is raised to remove the medical plastic bag. The saline mixture is then transplanted and plated for culture to test and determine the microorganisms present in the medical device. The flapping device of the utility model has a simple and reasonable overall structure and is easy to use and operate.
[0042] In order to further reduce the damage of the medical plastic bag during the beating process, a sponge gasket 112 is adhered and fixed to the outer wall of the rubber plate 18 for buffering protection.
