Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hospital infection control surface bacterial sampling device. Background Technology

[0002] As a key department in the hospital management system, the hospital infection control department undertakes extremely important responsibilities. One of its core tasks is to sample and test microorganisms after sterilization and disinfection within the hospital, and swab sampling is the most basic sampling and testing method within the hospital.

[0003] Currently, the shortcomings of existing hospital infection control surface bacterial sampling devices are that when using cotton swabs for sampling, one hand needs to hold the sampling bottle and the other hand needs to pull out the cap with the cotton swab before the cotton swab can be used for sampling. This operation process is cumbersome and inconvenient, thus reducing its practicality. To address this, we have designed a hospital infection control surface bacterial sampling device. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a hospital infection control surface bacteria sampling device that is highly practical, easy to operate, and has a simple structure, thus solving the problem of the cumbersome cotton swab sampling process mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a hospital infection control surface bacterial sampling device, comprising a rectangular shell and a pushing mechanism assembled outside the rectangular shell, and a flipping mechanism assembled outside the pushing mechanism, wherein a through hole is provided on the top of the rectangular shell and a rectangular groove is provided on one side of the rectangular shell;

[0006] The pushing mechanism includes a first hydraulic rod fixedly connected to one side of the rectangular shell surface and a U-shaped rod slidably connected to the rectangular shell surface, as well as a fixed frame mounted inside the U-shaped rod. The output end of the first hydraulic rod is fixedly connected to the inner wall of the U-shaped rod. Two cylinders are fixedly connected to both sides of the surface of the fixed frame, and one end of each cylinder passes through the U-shaped rod. A connecting block is fixedly connected to the inner wall of the fixed frame. Two baffles are rotatably connected to both sides of the connecting block. A first spring is fixedly connected to one side of the two baffles, and a first buffer rod is sleeved inside the first spring.

[0007] Optionally, the flipping mechanism includes two gears fixedly connected to one end of two cylinders and two racks meshing with the two gears. One side of each rack is slidably connected to the surface of a U-shaped rod. One end of each rack is fixedly connected to a second spring. Two second buffer rods are sleeved inside the two second springs. The other end of each second spring is fixedly connected to two protrusions. One side of each protrusion is fixedly connected to the surface of the U-shaped rod. A fixing rod is slidably connected to the surface of the U-shaped rod. One side of each fixing rod is fixedly connected to both sides of the surface of a rectangular shell. Two stops are fixedly connected to the top side of each fixing rod.

[0008] Optionally, a second hydraulic rod is fixedly connected to the inner bottom wall of the rectangular shell, and an L-shaped plate is fixedly connected to the output end of the second hydraulic rod. The L-shaped plate is slidably connected to the inner wall of the rectangular shell.

[0009] Optionally, the surface of the L-shaped plate is fixedly connected with several retaining rings, and the retaining rings are divided into six groups.

[0010] Optionally, a collection tube is snapped onto the surface of several retaining rings, and a cap is inserted into one end of the collection tube. A cotton swab is fixedly connected to the inner wall of the cap.

[0011] Optionally, the surfaces of the two baffles are provided with semi-circular grooves that are adapted to the surface of the cover, and one end of the two baffles extends to the outside of the fixing frame.

[0012] Optionally, the surface of the U-shaped rod has two grooves, and two sliders are slidably connected inside the two grooves. One side of each slider is fixedly connected to one side of a rack.

[0013] This utility model provides a hospital infection control surface bacterial sampling device, which has the following beneficial effects:

[0014] 1. This hospital infection control surface bacterial sampling device, through the design of a rectangular shell, a pushing mechanism, and a flipping mechanism, allows for efficient operation. When the collection bucket is secured to the retaining ring, a first spring presses against two baffles, while the semi-circular grooves on the baffle surfaces hold the lid in place. At this point, the first hydraulic rod is activated, moving the U-shaped plate towards the rectangular shell, pulling the lid out of the collection bucket until all the swabs are exposed. The rack is then held in place by a stop on the top side of the fixing rod, compressing the second spring. The rack drives the gear to rotate, which in turn rotates the cylinder on the U-shaped rod surface, causing the fixing frame to flip 180 degrees, ensuring the swabs are no longer facing the rectangular shell. Swab sampling can then be performed on the object surface. After the operation, the first hydraulic rod retracts, resetting the U-shaped rod. As the U-shaped rod moves, the rack is no longer held by the stop, the second spring resets, and the gear rotates, causing the fixing frame to rotate 180 degrees, aligning the swabs with the inside of the collection bucket. This design improves the ease of operation, eliminating the need for cumbersome manual procedures and enhancing the device's practicality.

[0015] 2. The hospital's surface bacteria sampling device, through the arrangement of a rectangular shell, a second hydraulic rod, an L-shaped plate, and a retaining ring, holds a collection tube with a cap on the retaining ring. After the first collection tube finishes sampling, the second hydraulic rod is opened, causing the L-shaped plate to rise. As the cap moves upward, the two baffles are opened by the upward movement of the cap, and the first spring is compressed until the cap of one end of the first collection tube disengages from the two baffles. Immediately afterwards, the cap of one end of the second collection tube is inserted into the semi-circular groove on the surface of the two baffles. This allows for multiple samplings without the need for manual replacement of the collection tube, greatly saving sampling time, improving work efficiency, and making the sampling process more convenient and efficient.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a hospital infection control surface bacterial sampling device, including a rectangular shell 1, a pushing mechanism 2 assembled outside the rectangular shell 1, and a flipping mechanism 3 assembled outside the pushing mechanism 2. The top of the rectangular shell 1 has a through hole, and one side of the rectangular shell 1 has a rectangular groove. The pushing mechanism 2 includes a first hydraulic rod 201 fixedly connected to one side of the surface of the rectangular shell 1 and a U-shaped rod 202 slidably connected to the surface of the rectangular shell 1, and a fixing frame 203 mounted inside the U-shaped rod 202. The output end of the first hydraulic rod 201 is fixedly connected to the U-shaped rod 202. Cylinders 204 are fixedly connected to both sides of the inner wall of rod 202 and the surface of fixing frame 203. One end of each cylinder 204 passes through U-shaped rod 202. Connecting block 205 is fixedly connected to the inner wall of fixing frame 203. Two baffles 206 are rotatably connected to both sides of connecting block 205. A first spring 207 is fixedly connected to the opposite side of the two baffles 206. A first buffer rod is sleeved inside the first spring 207. When the collecting cylinder 7 is stuck on the retaining ring 6, the first spring 207 abuts against the two baffles 206, and the semi-circular groove on the surface of the baffle 206 holds the cover 8 in place. At this time, the first hydraulic rod 201 is activated, which moves the U-shaped plate towards the rectangular shell 1, thereby pulling the cover 8 out from the surface of the collecting cylinder 7 until all the cotton swabs 9 are exposed.

[0024] Furthermore, the flipping mechanism 3 includes two gears 301 fixedly connected to one end of two cylinders 204 and two racks 302 meshing with the two gears 301. One side of each rack 302 is slidably connected to the surface of the U-shaped rod 202. A second spring 303 is fixedly connected to one end of each rack 302. Two second buffer rods are sleeved inside each second spring 303. Two protrusions 304 are fixedly connected to the other end of each second spring 303. One side of each protrusion 304 is fixedly connected to the surface of the U-shaped rod 202. A fixing rod 305 is slidably connected to the surface of the U-shaped rod 202. One side of the fixed rod 305 is fixedly connected to both sides of the surface of the rectangular shell 1. Two stops 306 are fixedly connected to the top side of the two fixed rods 305. The rack 302 is held in place by the stops 306 on the top side of the fixed rod 305, the second spring 303 is compressed, and the rack 302 drives the gear 301 to rotate. The gear 301 then drives the cylinder 204 to rotate on the surface of the U-shaped rod 202, causing the fixing frame 203 to rotate 180 degrees, so that the cotton swab 9 is no longer facing the rectangular shell 1. At this time, the cotton swab 9 can be sampled from the surface of the object. After the operation is completed, the first hydraulic rod 201 retracts, driving the U-shaped rod 202 to reset. With the movement of the U-shaped rod 202, the rack 302 is no longer held in place by the stops 306, the second spring 303 resets, and pushes the gear 301 to move, so that the fixing frame 203 rotates 180 degrees, so that the cotton swab 9 is aligned with the inside of the collection bucket. This design improves the convenience of the device operation, eliminating the need for cumbersome manual procedures, thereby enhancing the practicality of the device.

[0025] Furthermore, a second hydraulic rod 4 is fixedly connected to the inner bottom wall of the rectangular shell 1, and an L-shaped plate 5 is fixedly connected to the output end of the second hydraulic rod 4. The L-shaped plate 5 is slidably connected to the inner wall of the rectangular shell 1, wherein the second hydraulic rod 4 can drive the L-shaped plate 5 to slide inside the rectangular shell 1.

[0026] Furthermore, the surface of the L-shaped plate 5 is fixedly connected with several retaining rings 6, and the retaining rings 6 are divided into six groups.

[0027] Furthermore, a collection tube 7 is snapped onto the surface of several retaining rings 6, and a cap 8 is inserted into one end of the collection tube 7. A cotton swab 9 is fixedly connected to the inner wall of the cap 8.

[0028] Furthermore, the surfaces of the two baffles 206 are provided with semi-circular grooves that are adapted to the surface of the cover 8, and one end of the two baffles 206 extends to the outside of the fixing frame 203. The semi-circular grooves on the surface of the baffles 206 can better hold the cover 8.

[0029] Furthermore, two grooves are formed on the surface of the U-shaped rod 202, and two sliders 10 are slidably connected inside the two grooves. One side of each slider 10 is fixedly connected to one side of each rack 302. The sliders 10 can reduce the offset of the rack 302 when it moves.

[0030] In this invention, the working steps of the device are as follows:

[0031] First step: When the collection cylinder 7 is secured to the retaining ring 6, the first spring 207 presses against the two baffles 206, and at the same time, the semi-circular groove on the surface of the baffle 206 secures the cover 8. At this time, the first hydraulic rod 201 is activated, which moves the U-shaped plate toward the rectangular shell 1, thereby pulling the cover 8 off the surface of the collection cylinder 7 until all the cotton swabs 9 are exposed.

[0032] Step 2: The rack 302 is stopped by the stop 306 on one side of the top of the fixing rod 305, the second spring 303 is compressed, and the rack 302 drives the gear 301 to rotate. The gear 301 then drives the cylinder 204 to rotate on the surface of the U-shaped rod 202, causing the fixing frame 203 to rotate 180 degrees, so that the cotton swab 9 is no longer facing the rectangular shell 1. At this time, the cotton swab 9 can be used to sample the surface of the object. After the operation is completed, the first hydraulic rod 201 retracts, driving the U-shaped rod 202 to reset. With the movement of the U-shaped rod 202, the rack 302 is no longer stopped by the stop 306, the second spring 303 resets, and pushes the gear 301 to move, thereby causing the fixing frame 203 to rotate 180 degrees, so that the cotton swab 9 is aligned with the inside of the collection bucket.

[0033] The third step: The collection cylinder 7 equipped with the cover 8 is secured to the retaining ring 6. After the first collection cylinder 7 finishes sampling, the second hydraulic rod 4 is opened, causing the L-shaped plate 5 to rise. As the cover 8 moves upward, the two baffles 206 are opened by the upward movement of the cover 8, and the first spring 207 is compressed until the cover 8 at one end of the first collection cylinder 7 is disengaged from the two baffles 206. Immediately afterwards, the cover 8 inserted at one end of the second collection cylinder 7 is engaged into the semi-circular groove on the surface of the two baffles 206, thus allowing for multiple samplings.
