Description

Technical Field

[0001] The utility model relates to the technical field of microorganism detection, and particularly relates to a detection device for pathogenic microorganisms on the surface of a non-cavity endoscope. Background Art

[0002] Most thoracic surgeries require lung isolation and one-lung ventilation to facilitate the surgical operation. Double-lumen bronchial tubes (DLTs) are mostly used for lung isolation. When there are difficult airways causing difficulties in DLT intubation, bronchial blockers may be a better choice. Whether using DLTs or bronchial blockers for lung isolation, the use of a fiberoptic bronchoscope without a cavity for positioning is recommended.

[0003] In clinical work, there are also medical devices such as anorectal endoscopes, which will sample the microorganisms on the surface of the endoscope to detect the microorganisms.

[0004] When sampling microorganisms on a strip-shaped endoscope, the existing method is to let the eluent flow from the upper end to the lower end of the endoscope and then collect the eluent for culture to check whether the disinfection of the endoscope meets the standard. Or use a sampling swab to wipe the surface for sampling. There are problems such as inconvenient operation, easy leakage or insufficient sampling surface, resulting in inaccurate detection of microorganisms. Content of the Utility Model

[0005] Aiming at the technical problems existing in the prior art, the purpose of the utility model is to provide a detection device for pathogenic microorganisms on the surface of a non-cavity endoscope, which solves the problems of easy leakage or insufficient sampling surface when sampling microorganisms on a strip-shaped endoscope.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A detection device for pathogenic microorganisms on the surface of a non-cavity endoscope includes: a fixing component; a sampling component, which is arranged on the fixing component and has a sampling brush for contacting the surface of the strip-shaped endoscope; a collection cylinder connected to a sliding component; and a sliding component, which is slidably connected to the fixing component and can drive the collection cylinder to slidably contact the sampling brush.

[0008] As a preference, the sampling component includes an arc-shaped plate fixedly connected to the fixing component. The number of sampling brushes is multiple, and the multiple sampling brushes are evenly distributed along the arc surface of the arc-shaped plate.

[0009] As a preference, the sliding component includes a sliding rod and a support rod. The fixing component is provided with a first sliding groove, the extending direction of the first sliding groove faces the sampling component, the sliding rod is slidably connected to the first sliding groove, and the two ends of the support rod are respectively connected to the sliding rod and the collection cylinder.

[0010] As a preference, a second chute is provided on the chute wall of the first chute. The extending direction of the second chute is the same as that of the first chute. A first bump and a second bump that cooperate with the second chute are provided on the sliding rod. The first bump and the second bump are spaced apart on the sliding rod.

[0011] As a preference, the fixing assembly includes a fixing rod and a fixing frame. Both the sampling assembly and the sliding assembly are connected to the fixing rod, and the fixing rod is hinged to the fixing frame.

[0012] As a preference, a handle is provided on the fixing rod.

[0013] As a preference, a magnetic sheet is provided on the sliding rod, and a magnetic block is provided at one end of the first chute away from the sampling assembly. The magnetic sheet cooperates with the magnetic block to fix the sliding rod.

[0014] As a preference, a silica gel layer is provided on the outer surface of the handle.

[0015] Generally speaking, the present utility model has the following advantages:

[0016] 1. For the device for detecting pathogenic microorganisms on the surface of a non-cavity endoscope in the present utility model, the sampling brush contacts and samples most of the surface of the strip-shaped endoscope. The sliding assembly drives the collection cylinder to scrape off the microorganisms on the surface of the sampling brush to collect the microorganisms, and then the sliding assembly drives the collection cylinder away from the sampling brush to detect the sampled microorganisms, solving the problems of easy leakage of the eluent or insufficient collection surface.

[0017] 2. For the device for detecting pathogenic microorganisms on the surface of a non-cavity endoscope in the present utility model, through the cooperative setting of the fixing rod, the screw rod and the nut, it is convenient to adjust the angle between the handle and the fixing rod, facilitating the operation of the fixing rod, the arc plate and the sampling brush.

[0024] Embodiment 1

[0025] Refer to Figures 1-4 A detection device for pathogenic microorganisms on the surface of a cavity-free endoscope shown in the figure, including a fixed rod 1. The top end of the fixed rod 1 is fixedly connected with an arc-shaped plate 2. Two rows of sampling brushes are arranged on the inner side surface of the arc-shaped plate 2. The number of sampling brushes in each row is six. The two rows of sampling brushes and the arc-shaped plate form a sampling assembly. The two rows of sampling brushes are evenly distributed along the inner arc surface of the arc-shaped plate, facilitating the sampling of microorganisms on most of the outer surface of the endoscope, and the sampling is more comprehensive.

[0026] The fixing assembly includes a fixed rod 1 and a fixed frame 6. The sampling assembly and the sliding assembly are both connected to the fixed rod 1, and the fixed rod 1 is hinged to the fixed frame 6. The sliding assembly includes a sliding rod 4 and a support rod 17. The fixing assembly is provided with a first chute 13, and the extending direction of the first chute 13 faces the sampling assembly. The sliding rod 4 is slidably connected to the first chute 13. The two ends of the support rod 17 are respectively connected to the sliding rod 4 and the collection cylinder 5. The groove wall of the first chute 13 is provided with a second chute 10, and the extending direction of the second chute 10 is the same as that of the first chute 13. The sliding rod 4 is provided with a first convex block 11 and a second convex block 12 that cooperate with the second chute 10. The first convex block 11 and the second convex block 12 are arranged at intervals on the sliding rod 4.

[0027] The sampling brush 3 is adapted to the collection cylinder 5. The sliding rod 4 drives the collection cylinder 5 to move through the support rod 17. The number of the first convex blocks 11 is two, and the two first convex blocks 11 are located on both sides of the sliding rod 4 near the collection cylinder 5. The number of the second convex blocks 12 is two, and the two second convex blocks 12 are located on both sides of the sliding rod 4 far from the collection cylinder 5. The first convex block 11 and the second convex block 12 are both made of rubber blocks, and the first convex block 11 and the second convex block 12 are both adapted to the second chute 10, facilitating the sliding rod 4 to drive the collection cylinder 5 to adjust its position. When the sampling brush samples, the first convex block is adapted to the second chute, so that the collection cylinder is closer to the fixed rod 1 relative to the sampling brush, so that the collection cylinder does not contact or interfere with the endoscope during the sampling process of the sampling brush.

[0028] The fixed rod 1 and the fixed frame 6 are hinged by a screw rod. The screw rod passes through both sides of the fixed rod 1. The fixed frame is provided with a slot hole 14. The two ends of the screw rod are rotationally connected to the slot hole. Nuts are connected to the two ends of the screw rod. Drag the fixed rod 1 to deflect at an appropriate angle along the screw rod, twist the nut 8 until it abuts against the outer side of the fixed frame 6 and tighten it to limit the screw rod 7. Drag the handle 9 to drive the fixed rod 1 and the arc-shaped plate 2 to move. The sampling brush 3 moves along the strip-shaped surface of the endoscope, so that most of the microorganisms on the endoscope stay on the surface of the sampling brush 3. After sampling, drag the sliding rod 4 to drive the second convex block 12 to move. The second convex block 12 squeezes the inner wall of the first chute 13 and deforms until the second convex block 12 snaps into the second chute 10. Drag the sliding rod 4 to drive the support rod 17 and the collection cylinder 5 to slide along the second chute 10. The collection cylinder 5 scrapes off the microorganisms on the surface of the sampling brush 3 to collect the microorganisms. Pull out the sliding rod 4, that is, move the collection cylinder away from the sampling brush, and detect the sampled microorganisms.
