[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] Example 1

[0024] The medical sharp cutting and recovery device described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 3As shown, it comprises a vertically arranged box body 1, and the box body 1 is used to store the removed sharp objects;

[0025] A through slot 10 is provided on the top of the box body 1, which is connected from top to bottom. The through slot 10 is provided on the top of the box body 1, connecting the inside of the box body 1 with the outside, so as to facilitate the storage of sharp objects in the box body 1.

[0026] A vertical tube 7 is vertically installed in the through groove 10. When a sharp object needs to be removed, the end of the syringe or infusion needle tube with the needle is inserted into the vertical tube 7, and the needle is removed by the cutter 12;

[0027] The left and right side walls of the vertical tube 7 are provided with through holes that communicate with each other inside and outside, and a slide bar 14 is independently installed in each through hole. There are two through holes, which are respectively provided on the left and right side walls of the vertical tube 7. A slide bar 14 is horizontally installed in each through hole, and the slide bar 14 slides left and right along the hole depth direction of the through hole;

[0028] A cutter 12 is fixed to one end of one of the slide bars 14 located inside the vertical tube 7. The cutter 12 is fixed to the slide bar 14 inside the vertical tube 7. The cutter 12 can be fixed to the right end of the left slide bar 14 or the left end of the right slide bar 14. The cutter 12 can also be fixed to both slide bars 14. The infusion needle is placed between the slide bar 14 and the cutter 12. The needle is cut off by squeezing between the cutter 12 and the slide bar 14, and the needle is stored in the box body 1.

[0029] The two slide bars 14 are both fixed with slide blocks 8. Figure 1As shown, the right side wall of the left slider 8 is fixed to the left end of the left slider 14, and the right side wall of the right slider 8 is fixed to the right end of the right slider 14; the lower ends of the two sliders 8 are inserted into the through groove 10, and the outer side walls of the sliders 8 are wedge-shaped with the groove walls of the through groove 10. The left side wall of the left slider 8 is an inclined structure, which is wedge-shaped with the left groove wall of the through groove 10, and the right side wall of the right slider 8 is an inclined structure, which is wedge-shaped with the right groove wall of the through groove 10. When the two sliders 8 are pressed down, the groove wall of the through groove 10 pushes the two sliders 8 to move toward the vertical pipe 7, thereby pushing the two sliders 14 closer together; this paragraph of text as a whole constitutes a pushing component for pushing the slider 14 and the tool 12 to squeeze and cut the hose. When the pushing component is in use, when the left slider 8 is pressed downward, the left groove wall of the through groove 10 squeezes the inclined side wall of the left slider 8 , push the left slide block 8 to the right, drive the right end of the left slide bar 14 to move to the right, and when the right slide block 8 is pressed downward, the right groove wall of the through groove 10 squeezes the inclined side wall of the right slide block 8, and pushes the right slide block 8 to the left, drives the left end of the right slide bar 14 to move to the left, so that the tool 12 and the slide bar 14 squeeze each other and separate the sharp tool; of course, the pushing component can also use an electric push rod, and electric push rods are installed on the left and right groove walls of the through groove 10, and the movable end of the electric push rod is fixed on the slide bar 14, and the two slide bars 14 are pushed to move by the extension and locking of the electric push rod. The electric push rod is a prior art, which is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The housing of the electric push rod is fixed on the groove wall of the through groove 10, and the push rod of the electric push rod is fixed on the slide bar 14;

[0030] A spring 13 is mounted on the slide bar 14 on the outside of the vertical tube 7, one end of the spring 13 is fixed on the side wall of the slider 8, and the other end is fixed on the outer wall of the vertical tube 7; when the spring 13 is in a natural state, the tool 12 is separated from the other slide bar 14, and the slider 8 is pushed away from the vertical tube 7 by the spring 13. When there is no sharp object to be separated, the two slide bars 14 are separated, which is convenient for next use; this paragraph of text as a whole constitutes a reset component for resetting the slide bar 14 and the tool 12 after cutting off the hose. When the reset component is in use, after the sharp object is separated, the two slide bars 8 are pushed toward the outside of the vertical tube 7 under the action of the spring 13, thereby separating the two slide bars 14 and restoring the two slide bars 14 to their original positions. After the two slide bars 8 move to both sides, the two slide bars 8 are squeezed out of the through groove 10 by the side walls of the through groove 10.

[0031] When the present embodiment is used, the end of the infusion needle tube with the needle tip is inserted into the vertical tube 7, the hose of the infusion needle tube is placed between the cutter 12 and the slide bar 14, the two slide bars 14 are brought together by the pushing assembly, the hose is cut off by the extrusion between the cutter 12 and the slide bar 14, and the needle tip is stored in the box body 1, the end of the syringe with the needle tip is inserted into the vertical tube 7, the two slide bars 14 are brought together by the pushing assembly, the needle of the syringe is clamped by the slide bar 14 and the cutter 12, the syringe barrel is pulled upward, the syringe barrel and the needle tip are separated, and the needle tip is stored in the box body 1, after the needle tip is separated, the slide bar 14 and the cutter 12 are reset by the reset assembly to facilitate the next use, and when the infusion hose and syringe are separated from the needle tip, the vertical tube 7 is used to block the liquid medicine and blood overflowing from the syringe and the infusion hose to prevent environmental pollution.

[0032] Example 2

[0033] This embodiment further illustrates the technology. Figure 1 As shown, the tops of the left and right groove walls of the through groove 10 are rounded, and the tops of the groove walls of the through groove 10 are in an arc structure. When the slider 8 is pressed downward, the side walls of the slider 8 rub against the groove walls, and the groove walls with an arc structure change the point contact into surface contact, thereby reducing the friction between the side walls of the slider 8 and the groove walls, and extending the service life of the slider 8 and the through groove 10.

[0034] Example 3

[0035] This embodiment further illustrates the technology. Figure 1 and Figure 3 As shown, one end of the two slide bars 14 located in the vertical tube 7 is vertically fixed with a fixing plate 4, and there are two fixing plates 4, which are respectively fixed to the right end of the left slide bar 14 and the left end of the right slide bar 14;

[0036] The tool 12 is fixed on one of the fixing plates 4. The diameter of the through hole is smaller than the length of the fixing plate 4. The fixing plate 4 limits the slide bar 14 to prevent the reset component from pulling the slide bar 14 out of the through hole and preventing the slide bar 14 from falling off from the through hole.

[0037] In this embodiment, when the two slide bars 14 are brought close together, the two fixing plates 4 are also driven to fit together. When the needle of the syringe is separated, the needle of the syringe is clamped by the two fixing plates 4, which helps to separate the needle tube from the needle.

[0038] Example 4

[0039] This embodiment further illustrates the technology. Figure 1As shown, the length of the vertical tube 7 above the slide bar 14 is between 8 cm and 10 cm. The length of the vertical tube 7 above the slide bar 14 will directly affect the blocking effect of the vertical tube 7 on the liquid. If the length of the vertical tube 7 is too long, the production cost will be increased. If the length of the vertical tube 7 is too short, the liquid in the syringe and the infusion hose will overflow, polluting the environment. The length of the vertical tube 7 above the slide bar 14 can be selected as any value between 8 cm, 10 cm, 9 cm and 8 cm-10 cm. The length of the vertical tube 7 above the slide bar 14 must ensure that the vertical tube 7 can completely block the liquid overflowing from the syringe and the infusion hose when they are separated from the needle.

[0040] A pressing plate 5 is mounted on the upper end of the vertical tube 7, and the pressing plate 5 is used by medical personnel to press the vertical tube 7 downward, thereby driving the two sliding blocks 8 to move downward.

[0041] A sponge pad 6 is fixed to the top of the inner wall of the vertical tube 7. The sponge pad 6 is annular in structure. The needle tube and the infusion needle tube pass through the sponge pad 6 when the needle is separated. The sponge pad 6 further prevents liquid from overflowing when the needle is separated, thereby preventing environmental pollution.

[0042] Example 5

[0043] This embodiment further illustrates the technology. Figure 1 As shown, a fixing ring 3 is fixed to the outer wall of the vertical tube 7, a connecting rod 2 is vertically fixed to the lower end of the fixing ring 3, a through hole is opened on the top of the box body 1 for the connecting rod 2 to pass through, and a baffle 9 is horizontally fixed to the lower end of the connecting rod 2 after passing through the through hole. The aperture of the through hole is smaller than the width of the baffle 9. After the needle separation is completed, the two sliders 8 will withdraw from the through slot 10, and the baffle 9 will limit the vertical tube 7 to prevent the vertical tube 7 from completely falling off from the through slot 10.

[0044] Example 6

[0045] This embodiment further illustrates the technology. Figure 1 As shown, the box body 1 is made of transparent material. Since the operating instructions require that sharp objects cannot exceed three quarters of the volume of the box body 1, the box body 1 made of transparent material can visually observe the storage status of sharp objects in the box body 1 and deal with the sharp objects in time.
