the cutting mechanism 4 comprises a second electric push rod 41 and a cutting tool 42; one end of a second electric push rod 41 is fixedly connected with the top wall in the box body 1, and the other end of the second electric push rod is fixedly connected with a cutting tool 42;

when the medical instrument box works, the sharps box in the prior art needs manual auxiliary operation, one end of the infusion tube with the needle is manually inserted into the shearing device, and the hose part and the needle part of the infusion tube are separated by the shearing device and then are separately stored and recycled; the medical staff wastes time and labor in cutting and separating the infusion tube, and the precious time of the medical staff is wasted; the needle head separation needs manual assistance, so that the operation is inconvenient;

the sharps box in the prior art needs manual auxiliary operation, and one end of the infusion tube with the needle head is manually inserted into the shearing device, so that the shearing and the separation of one infusion tube are time-consuming and labor-consuming, and valuable time of medical personnel is wasted;

therefore, after the transfusion or injection of a patient is finished, a medical worker pulls out a needle of the transfusion tube, and then the transfusion tube is placed into the box body 1 through the recovery inlet 2, so that the transfusion tube enters the first box 6, at the moment, the controller controls the driving motor 32 to drive the bidirectional threaded rod 9 to rotate and electrify the electromagnet block 31, so that the electromagnet block 31 moves leftwards through the bidirectional threaded rod 9, and the electromagnet block 31 generates magnetic force; because the needle of the infusion tube is made of 304 stainless steel and can be attracted by the magnet, when the electromagnet block 31 passes above the first box 6, the electromagnet block 31 generates attraction force on the needle of the infusion tube, so that the needle is attracted on the electromagnet block 31 and moves along with the electromagnet block 31; when the electromagnet block 31 is driven to move to the leftmost end, the bidirectional threaded rod 9 continues to rotate, so that the electromagnet block 31 and the needle head move rightwards to the initial position; when the needle moves rightwards, the needle pulls the hose part of the infusion tube to drive the infusion tube to move together;

after the electromagnet block 31 returns to the initial position, the controller controls the output end of the second electric push rod 41 to drive the cutting tool 42 to move downwards, so that the cutting tool 42 moves downwards until the cutting tool 42 is positioned between the first box 6 and the second box 7, at the moment, the cutting tool 42 cuts off the space between the needle head and the hose of the infusion tube, then the controller controls the electromagnet block 31 to stop electrifying, the electromagnet block 31 stops generating magnetic force, the needle head loses the adsorption effect of the electromagnet block 31 and falls into the second box 7, the hose part of the infusion tube returns to the first box 6, then the controller controls the output end of the second electric push rod 41 to drive the cutting tool 42 to return to the initial position, and then the hose part and the needle head part of the infusion tube are separated;

according to the invention, the electromagnet block 31 moves back and forth to adsorb the needle head and drive the needle head to move together, then the cutting tool 42 cuts and separates the hose part and the needle head part of the infusion tube, so that the separation of the needle head on the infusion tube is completed.

Example 2:

the difference compared to example 1 is that:

in this embodiment, the inner wall of the box body 1 is fixedly connected with two scraping blocks 43; the scraping blocks 43 are positioned at the upper side and the lower side of the electromagnet block 31 and are contacted with the electromagnet block 31;

in this embodiment, the left side surface of the cutting tool 42 is fixedly connected with a fixing plate 44; the fixed plate 44 is connected with a pressing block 46 through a telescopic spring 45; two ends of the extension spring 45 are fixedly connected with the fixed plate 44 and the pressing block 46 respectively; the mass 46 is made of a flexible material, such as rubber.

In this embodiment, the first box 6 is in the shape of an inverted right trapezoid; an opening 8 of the second box 7 is hinged with a baffle plate 48 through a first torsion spring 47; the hinged position of the baffle 48 and the second box 7 is far away from the first box 6, the baffle 48 keeps a horizontal state under the action of the first torsion spring 47 and seals the opening 8 of the second box 7; an inverted L-shaped block 49 capable of pushing the flap 48 is attached to the cutter 42.

In this embodiment, the distance between the upper ends of the first and

second cases

6 and 7 and the lower end of the electromagnet block 31 in the vertical direction is 5 mm.

When the device works, in the process that the electromagnet block 31 brings the needle back to the initial position, the electromagnet block 31 is in contact with the scraping block 43, and along with the continuous movement of the electromagnet block 31, the scraping block 43 pushes the needle below the electromagnet block 31 to enable the needle to move leftwards on the electromagnet block 31, so that the needle is adsorbed on the left side surface of the electromagnet block 31, meanwhile, the hose of the infusion tube is lapped on the right side of the first box 6, the needle keeps horizontal under the suction force of the electromagnet block 31 and the tension force of the hose of the infusion tube, and therefore, the distance between the cutting tool 42 and the electromagnet block 31 in the horizontal direction is basically the same as the length of the needle, the length of the hose attached to the needle after cutting is minimum, and the cutting effect is optimal;

when the second electric push rod 41 drives the cutting tool 42 to move downwards, the cutting tool 42 drives the pressing block 46 to move downwards, the pressing block 46 is firstly contacted with the hose of the infusion tube and clamps the hose together with the upper end of the first box 6, and the hose is prevented from moving when the cutting tool 42 is contacted with the hose; as the cutting tool 42 continues to move downwards, the telescopic spring 45 is compressed, the cutting tool 42 is in contact with and cuts off the hose, the inverted-L-shaped block 49 on the cutting tool 42 is in contact with the baffle 48 and pushes the baffle 48 downwards, so that the first torsion spring 47 is twisted, a gap is exposed between the baffle 48 and the opening 8 of the second box 7, the controller controls the electromagnet block 31 to stop electrifying at the moment, the cut needle falls on the baffle 48 and slides into the second box 7 along the baffle 48, then the second electric push rod 41 drives the cutting tool 42 and the inverted-L-shaped block 49 of the pressing block 46 to return to the initial position, the baffle 48 rotates upwards under the action of the torsion force of the first torsion spring 47, and the second box 7 is sealed again;

when a medical staff puts a syringe into the recovery inlet 2, the syringe is adsorbed on the electromagnet block 31 along with the needle and moves rightwards along with the electromagnet block 31, when the syringe is adsorbed below or on the right side of the electromagnet block 31, the syringe is contacted with the inclined side wall of the first box 6, so that the needle of the syringe moves leftwards on the electromagnet block 31 under the blocking of the side wall of the first box 6 until the needle is adsorbed on the left side surface of the electromagnet block 31, and as the electromagnet block 31 continues to move, the syringe keeps horizontal under the action of the suction force of the electromagnet block 31 and the supporting force of the side wall of the first box 6, thereby preventing the situation that the needle is adsorbed on the right side surface of the electromagnet block 31 and the needle is clamped between the electromagnet block 31 and the scraping blocks 43 when the electromagnet block 31 enters between the two scraping blocks 43; the distance between the upper ends of the first box 6 and the second box 7 and the lower end of the electromagnet block 31 in the vertical direction is 5mm, so that the side wall of the first box 6 can block most of syringes; when the cutting tool 42 moves downwards, the pressing block 46 presses the syringe part of the injector, and the pressing block 46 is connected with the fixing plate 44 through the telescopic spring 45, so that the pressing block 46 can press injectors with different specifications; when the cutting tool 42 cuts the needle head on the syringe, the needle head falls into the second box 7, and the needle cylinder part falls into the first box 6 along the inclined side wall of the first box 6;

according to the invention, the pressing block 46 is arranged, so that the hose of the infusion tube can be clamped when the needle head is cut off, the hose is prevented from moving, meanwhile, the needle cylinder of the injector can be clamped, the pressing block 46 is fixed through the telescopic spring 45, so that the pressing block 46 can clamp the needle cylinders of the injectors with different specifications, and the using effect of the syringe is enhanced.

Example 3:

in this embodiment, a sensor 5 is fixedly connected in the recovery inlet 2; the sensor 5 is in circuit connection with the controller; the sensor 5 is a photosensor.

In this embodiment, the lower end surface of the first box 6 is slidably connected with the collecting box 51, and the lower end of the first box 6 is uniformly provided with through holes 61; the collection box 51 and the second box 7 are slidably connected to the case 1.

In this embodiment, a desiccant capable of absorbing liquid, such as lime powder, is stored in the collection box 51.

In this embodiment, the upper end of the collecting box 51 is provided with a through hole 71.

The medical staff puts the infusion tube or the injector into the recovery inlet 2, so that the infusion tube or the injector slides downwards and passes through the sensor 5, and the sensor 5 controls the driving motor 32 to drive the bidirectional threaded rod 9 to rotate after 3 seconds, so that the electromagnet block 31 moves to adsorb the needle head of the infusion tube or the injector;

after the cutting tool 42 cuts the needle head of the infusion tube, the residual liquid medicine in the infusion tube flows out through the cut, the liquid medicine enters the collection box 51 through the through hole 61 formed in the lower end of the first box 6, so that the infusion tube in the first box 6 is in a dry state, meanwhile, lime powder is stored in the collection box 51, the liquid medicine can be absorbed and sterilized, and the liquid medicine is prevented from breeding bacteria and emitting odor after being stored for a long time in the infusion tube; the upper end of the collecting box 51 is provided with a through hole 71, when airflow flows in the surrounding environment, the airflow can enter the first box 6 through the through hole 71 and the through hole 61, and the drying of the infusion tube is enhanced; medical personnel take out first box 6, No. two box 7 and collect box 51 through opening 8 when first box 6 or No. two box 7 are full, press again and collect box 51 and pull first box 6, make and separate between first box 6 and the collection box 51, pour out the syringe needle of retrieving, the transfer line hose, the cylinder and the lime powder that absorbs the liquid medicine after that, put into dry lime powder and insert first box 6 into collection box 51 in collecting box 51 again, will collect box 51 and No. two box 7 and slide in box 1 at last to accomplish the transfer of syringe needle and transfer line hose.
