Description

Technical Field

[0001] This utility model belongs to the field of puncture needle tube sterilization machines, specifically, it relates to a reciprocating puncture needle tube sterilization machine. Background Technology

[0002] Puncture needles are commonly used medical devices that can be used to puncture organs or tissues or to inject drugs, such as arterial puncture needles and venous puncture needles.

[0003] Chinese Patent No. CN110403714A discloses a reciprocating puncture needle tube sterilizer. When the crank-slider mechanism is started, the crank-slider mechanism rotates and drives the lifting plate to make a reciprocating motion of rising and falling. When it rises to the limit position, the crank-slider mechanism stops, so that the lifting plate is held at the highest point. At this time, the support components on the lifting plate pass through the needle tube inlet and outlet, and a puncture needle tube to be cleaned and sterilized is installed on each set of support components until all support components on the lifting plate are equipped with puncture needle tubes.

[0004] However, the aforementioned reciprocating puncture needle tube sterilizer, which installs the puncture needle tube on the support assembly and positions the puncture needle tube by inserting brush bristles into the side of the puncture needle tube, although the positioning efficiency is fast, causes the brush bristles to lose the effect of continuous brushing of the puncture needle tube, affecting the cleaning effect on the inner wall of the puncture needle tube.

[0005] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this embodiment provides a reciprocating puncture needle sterilizer, including a sealed cabinet 1, a cleaning tank 2 inside the sealed cabinet 1, a discharge valve connected to the side of the cleaning tank 2 to facilitate the discharge of disinfectant alcohol from the cleaning tank 2, a positioning mechanism 3 inside the cleaning tank 2, a mounting frame 4 reciprocatingly sliding inside the sealed cabinet 1, a first driving mechanism 5 for driving the mounting frame 4 to reciprocate horizontally on the top surface of the inner wall of the sealed cabinet 1, two guide mechanisms 6 between the top surface of the inner wall of the sealed cabinet 1 and the mounting frame 4, a plurality of cleaning brush rods 7 rotatably engaging on the bottom surface of the mounting frame 4, the outer side of the cleaning brush rods 7 being evenly distributed with bristles, and a second driving mechanism 8 for driving the cleaning brush rods 7 to rotate inside the mounting frame 4.

[0026] Disinfecting alcohol is added to the cleaning tank 2, and then the needle tube of the puncture needle is fitted onto the cleaning brush rod 7. The bristles on the cleaning brush rod 7 position the needle tube of the puncture needle. After the needle tubes of the puncture needles are fitted onto all the cleaning brush rods 7, the first drive mechanism 5 is activated to move the mounting frame 4 and the cleaning brush rod 7 downward, so that the needle tube of the puncture needle slides into the positioning mechanism 3. The positioning mechanism 3 is used to improve the positioning efficiency of the needle tubes of multiple puncture needles. Then, the first drive mechanism 5 is activated to drive the cleaning brush rod 7 to move vertically back and forth to clean the inner wall of the needle tube of the puncture needle. The second drive mechanism 8 is activated to drive the cleaning brush rod 7 to rotate and clean the inner wall of the needle tube of the puncture needle, which improves the cleaning effect on the inner wall of the needle tube of the puncture needle.

[0027] Please see Figure 2-3 As shown, in this embodiment, the sealing cabinet 1 is equipped with ultraviolet lamps 9 on both sides. The sealing cabinet 1 is rotated and fitted with a cabinet door on one side, which facilitates the release of the positioning mechanism 3 and the activation of the first drive mechanism 5 to remove the puncture needle tube from the cleaning pool 2 for sterilization by the ultraviolet lamps 9.

[0028] Please see Figure 2 As shown, the first drive mechanism 5 in this embodiment includes a first electric push rod 501 located on the top surface of the inner wall of the sealed cabinet 1, a first servo motor 502 located at the output end of the first electric push rod 501, a drive shaft 503 located at the output end of the first servo motor 502, a guide channel 504 located on the side of the drive shaft 503, a cylinder 505 located on the upper side of the mounting frame 4, and a protrusion 506 located on the inner wall of the cylinder 505 and within the guide channel 504. The guide channel 504 includes two channels symmetrically located on the side of the drive shaft 503, with the ends of the two channels connected to each other. The channels have a semi-circular spiral structure, which facilitates the first servo motor 502 to drive the drive shaft 503 to rotate. The guide channel 504 on the drive shaft 503 presses against the protrusion 506 on the cylinder 505, thereby driving the mounting frame 4 and the cleaning brush rod 7 to move vertically back and forth.

[0029] Please see Figure 2 As shown, the guide mechanism 6 in this embodiment includes a guide cylinder 601 fixed to the top surface of the inner wall of the sealing cabinet 1 and a guide rod 602 fixed to the upper side of the mounting frame 4. One end of the guide rod 602 is slidably fitted inside the guide cylinder 601, which facilitates the sliding of the guide rod 602 inside the guide cylinder 601 and guides the mounting frame 4 to slide stably in the sealing cabinet 1.

[0030] Please see Figure 2-3As shown, the second drive mechanism 8 in this embodiment includes a second servo motor 801 disposed in the mounting frame 4, a worm gear 802 disposed at the output end of the second servo motor 801, and a worm wheel 803 disposed at one end of the cleaning brush rod 7 that extends into the mounting frame 4. One end of the worm gear 802 is rotatably fitted on the inner wall of the mounting frame 4. A bearing is embedded in the bottom surface of the inner wall of the mounting frame 4. The upper end of the cleaning brush rod 7 is fixed in the bearing, which facilitates the second servo motor 801 to drive the worm gear 802 to rotate and drive the worm wheel 803 to rotate, thereby driving the cleaning brush rod 7 to rotate and clean the inner wall of the puncture needle tube, which facilitates the improvement of the cleaning effect on the inner wall of the puncture needle tube.

[0031] Please see Figure 2 As shown, the positioning mechanism 3 of this embodiment includes two second electric push rods 301 respectively disposed on opposite sides of the cleaning pool 2, and a clamping plate 302 disposed at one end of the output shaft of the second electric push rod 301 extending into the cleaning pool 2. Both clamping plates 302 are provided with multiple arc-shaped notches 303 on their opposite inner sides, so as to facilitate the second electric push rod 301 to drive the clamping plate 302 to slide and position the needle tube of the puncture needle in the arc-shaped notches 303 of the two clamping plates 302.

[0032] Working principle: Add disinfectant alcohol to the cleaning tank 2, then place the needle tube of the puncture needle onto the cleaning brush rod 7. The bristles on the cleaning brush rod 7 position the needle tube of the puncture needle. After all the cleaning brush rods 7 have needle tubes of puncture needles on them, activate the first electric push rod 501 to move the mounting frame 4 and the cleaning brush rods 7 downwards, allowing the needle tube of the puncture needle to slide between the two clamping plates 302. Then, activate the second electric push rod 301 to drive the clamping plates 302 to slide, positioning the needle tube of the puncture needle within the arc-shaped notch 303 of the two clamping plates 302, which improves the needle tube positioning efficiency of multiple puncture needles. Then, activate the first servo motor 502 to drive the transmission shaft 503 to rotate. The guide on the transmission shaft 503... The channel 504 squeezes the protrusion 506 on the cylinder 505, causing the cleaning brush rod 7 to move vertically back and forth to clean the inner wall of the puncture needle tube. The second servo motor 801 is turned on to drive the worm gear 802 to rotate the worm wheel 803, which in turn drives the cleaning brush rod 7 to rotate and clean the inner wall of the puncture needle tube, thus improving the cleaning effect on the inner wall of the puncture needle tube. After cleaning and disinfection, the side opening of the puncture needle tube is oriented towards the length direction of the two clamps 302, so that the bristles on the cleaning brush rod 7 pass through the side opening of the puncture needle tube and extend into the gap between the two clamps 302. Then the positioning mechanism 3 is released and the first drive mechanism 5 is turned on to lift the puncture needle tube out of the cleaning pool 2 and sterilize it with the ultraviolet lamp 9.
