Detailed Description

The invention is further described in connection with the following detailed description in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.

Example 1:

a medical waste treatment recovery apparatus comprising:

a case 1;

a recovery inlet 2;

a traction mechanism 3; the traction mechanism 3 is arranged in the box body 1 and is used for traction of the metal needle;

a cutting mechanism 4; the cutting mechanism 4 is arranged in the box body 1 and is used for cutting off the pulled metal needle;

also comprises a controller; the controller is used for controlling the automatic operation of the traction mechanism 3 and the cutting mechanism 4;

the box 1 is internally provided with a first box 6 and a second box 7, and the box 1 is provided with an opening 8 corresponding to the positions of the first box 6 and the second box 7.

In the present embodiment, the traction mechanism 3 includes an electromagnet block 31, a driving motor 32, and a sliding groove 33; the sliding grooves 33 are formed on two symmetrical inner walls of the box body 1; the electromagnet block 31 is in sliding fit with the sliding groove 33; the driving motor 32 is fixedly connected to the side wall of the sliding groove 33, and the output shaft of the driving motor 32 is fixedly connected with the bidirectional threaded rod 9; the bidirectional threaded rod 9 is in threaded fit with the electromagnet block 31;

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

when the sharp instrument box in the prior art works, the manual auxiliary operation is needed, 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 stored and recycled; the medical staff takes time and labor when cutting and separating the infusion tube, and precious time of the medical staff is wasted; the needle head separation needs manual assistance, so that the operation is inconvenient;

the edge tool box in the prior art needs manual auxiliary operation, and one end of the infusion tube with the needle is manually inserted into the shearing device, so that the shearing and separating of one infusion tube are time-consuming and labor-consuming, and precious time of medical staff is wasted;

therefore, after transfusion or injection of a patient is finished, a medical staff pulls out a needle head of the transfusion tube, then the transfusion tube is put into the box body 1 through the recovery inlet 2, so that the transfusion tube enters the one-size box 6, at the moment, the controller controls the driving motor 32 to rotate with the bidirectional threaded rod 9 and electrifies the electromagnet block 31, so that the bidirectional threaded rod 9 enables the electromagnet block 31 to move leftwards, 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 over the one-size box 6, the electromagnet block 31 generates attraction to the needle of the infusion tube, so that the needle is attracted to the electromagnet block 31 and moves together with the electromagnet block 31; when the electromagnet block 31 is carried 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 and moves together with the infusion tube;

after the electromagnet block 31 returns to the initial position, the controller controls the output end of the second-size electric push rod 41 to move downwards with the cutting tool 42, so that the cutting tool 42 moves downwards until the cutting tool 42 is positioned between the first-size box 6 and the second-size box 7, at the moment, the cutting tool 42 cuts off a needle head and a 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 of the electromagnet block 31 and falls into the second-size box 7, the hose part of the infusion tube returns to the first-size box 6, then the controller controls the output end of the second-size electric push rod 41 to return to the initial position with the cutting tool 42, and finally the separation of the hose part and the needle head part of the infusion tube is completed;

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

Example 2:

the difference from example 1 is that:

in the embodiment, two scraping blocks 43 are fixedly connected to the inner wall of the box body 1; the scraping blocks 43 are positioned at the upper and lower sides of the electromagnet block 31 and contact with the electromagnet block 31;

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

In this embodiment, the first box 6 is in the shape of an inverted right trapezoid; a baffle 48 is hinged to the opening 8 of the second box 7 through a first torsion spring 47; the hinge joint position of the baffle 48 and the second box 7 is far away from the first box 6, and 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 baffle 48 is fixedly connected to the cutting tool 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 5mm.

When the electromagnetic device works, the electromagnetic block 31 is contacted with the scraping block 43 in the process of returning the needle to the initial position with the needle, and as the electromagnetic block 31 continues to move, the scraping block 43 pushes the needle below the electromagnetic block 31 to move leftwards on the electromagnetic block 31, so that the needle is adsorbed on the left side surface of the electromagnetic block 31, meanwhile, a hose of a transfusion tube is lapped on the right side of the one-size box 6, the needle is kept transverse under the suction force of the electromagnetic block 31 and the pulling force of the hose of the transfusion tube, so that the distance between the cutting tool 42 and the electromagnetic block 31 in the transverse direction is basically the same as the length of the needle, the length of the hose attached to the needle part after cutting is minimized, 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 moves downwards along with the pressing block 46, 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, so that the hose is prevented from moving when the cutting tool 42 is contacted with the hose; as the cutter 42 continues to move downward, the expansion spring 45 is compressed, the cutter 42 contacts the hose and cuts off the hose, the inverted L-shaped block 49 on the cutter 42 contacts the baffle 48 and pushes the baffle 48 downward, so that the first torsion spring 47 is twisted, a gap is exposed between the baffle 48 and the opening 8 of the second-size box 7, at the moment, the controller controls the electromagnet block 31 to stop being electrified, so that the cut needle falls onto the baffle 48 and slides into the second-size box 7 along the baffle 48, then the second-size electric push rod 41 returns to the initial position with the cutter 42 and the inverted L-shaped block 49 of the pressing block 46, and the baffle 48 rotates upward under the torsion force of the first torsion spring 47 to seal the second-size box 7 again;

the opening 8 of the second-size box 7 is sealed by the baffle 48, so that when the electromagnet is electrified, the needle heads collected in the second-size box 7 are adsorbed on the inverted magnet blocks under the action of magnetic force, and the needle heads adsorbed on the infusion tube in the first-size box 6 are influenced;

when medical staff puts the injector into the recycling inlet 2, the injector is adsorbed on the electromagnet block 31 along with the needle head and moves rightwards along with the electromagnet block 31, when the injector is adsorbed below or on the right side of the electromagnet block 31, the injector contacts with the inclined side wall of the first-size box 6, so that the injector is blocked by the side wall of the first-size box 6, the needle head of the injector moves leftwards on the electromagnet block 31 until the needle head is adsorbed on the left side surface of the electromagnet block 31, and the injector keeps transverse under the action of the suction force of the electromagnet block 31 and the supporting force of the side wall of the first-size box 6 along with the continued movement of the electromagnet block 31, and therefore the situation that the needle head is adsorbed on the right side surface of the electromagnet block 31 is prevented, and when the electromagnet block 31 enters between the two scraping blocks 43, the needle head is clamped between the electromagnet block 31 and the scraping blocks 43 is prevented; 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 cutter 42 moves downward, the pressing block 46 presses the cylinder 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 of different specifications; when the cutter 42 cuts the needle on the syringe, the needle falls into the second-size box 7, and the cylinder part falls into the first-size box 6 along the inclined side wall of the first-size box 6;

the pressing block 46 is arranged, so that the hose of the infusion tube can be clamped when the needle is cut off, the hose is prevented from moving, the syringe barrel of the syringe can be clamped, the pressing block 46 is fixed through the telescopic spring 45, and the pressing block 46 can clamp syringe barrels of different specifications, so that the use effect of the infusion tube is enhanced.

Example 3:

the difference from example 1 is that:

in the embodiment, a sensor 5 is fixedly connected in the recovery inlet 2; the sensor 5 is connected with the controller through a circuit; the sensor 5 is a photoelectric sensor.

In this embodiment, the collecting box 51 is slidably connected to the lower end surface of the first box 6, and the through holes 61 are uniformly formed in the lower end of the first box 6; the collection box 51 and the second box 7 are slidably connected with 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 collection box 51 is provided with a through hole 71.

The medical staff puts the infusion tube or the injector into the recycling 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 of the infusion tube or the injector;

after the needle head of the infusion tube is cut off by the cutting tool 42, the residual liquid medicine in the infusion tube flows out through the incision, and the liquid medicine enters the collecting box 51 through the through hole 61 formed in the lower end of the first-size box 6, so that the infusion tube in the first-size box 6 is in a dry state, and meanwhile, lime powder is stored in the collecting box 51, so that the liquid medicine can be absorbed and disinfected, bacteria are prevented from breeding due to long-time storage of the liquid medicine in the invention, and malodor is prevented from being emitted; a through hole 71 is formed in the upper end of the collection box 51, when air flows in the surrounding environment, the air can enter the first box 6 through the through hole 71 and the through hole 61, and drying of the infusion tube is enhanced; medical staff draws out the first-size box 6, the second-size box 7 and the collecting box 51 through the opening 8 when the first-size box 6 or the second-size box 7 is full, presses the collecting box 51 again and pulls the first-size box 6 to separate the first-size box 6 from the collecting box 51, then pours out the recovered needle head, the hose of the infusion tube, the needle cylinder and the lime powder for absorbing the liquid medicine, puts the dried lime powder into the collecting box 51 again, inserts the first-size box 6 into the collecting box 51, and finally slides the collecting box 51 and the second-size box 7 into the box 1, thereby completing the transfer of the needle head and the infusion hose.
