Description

Technical Field

[0001] The present invention relates to the technical field of medical care waste transportation, and in particular to a transportation-type pre-recovery device for medical care waste. Background Art

[0002] Medical care waste refers to waste generated during medical treatment and nursing, mainly including disposable medical devices, gauze, cotton swabs, gloves, drug residues, syringes, etc. This type of waste has potential biohazards and may carry pathogens or be contaminated, so its treatment must strictly comply with medical waste management regulations. When handling medical care waste, in order to ensure the safety of relevant staff, garbage bags containing waste are usually placed in pre-recovery devices for transportation, and then transported and processed in a unified manner.

[0003] In the related art, garbage bags containing medical care waste are mainly pre-recovered through transfer-type pre-recovery devices. However, in the process of recycling and storing waste, the waste may release harmful gases. In order to prevent the spread of harmful gases, a protective cover is usually provided on the transfer-type pre-recovery device. By closing the protective cover, the harmful gas can be prevented from leaking outward. However, when the staff puts the waste, the protective cover needs to be opened. At this time, the harmful gas inside the transfer device may be emitted outward, especially in the process of putting waste into the transfer-type pre-recovery device. The air pressure inside the device will increase instantly. In order to achieve air pressure balance, the air inside the device will flow from the opening to the external environment with lower pressure, forming an outward airflow discharged directly toward the face of the person putting the waste. At this time, the person putting the waste may directly inhale some of the harmful gas, which may cause potential harm to the health of the person.

The upper surface of the fourth bevel gear 804 is fixedly connected to the third shaft rod 805, and the rotation of the fourth bevel gear 804 can control the third shaft rod 805 to rotate, and the upper end surface of the third shaft rod 805 passes through the interior of the connecting ring 701 and is rotatably connected to the inner wall of the transfer box 101. Fig.10The outer wall of the third shaft 805 is circumferentially fixedly connected with a plurality of triangular driving blocks 806, and when the third shaft 805 rotates, the plurality of triangular driving blocks 806 can be driven to move, and the plurality of triangular driving blocks 806 are all located inside the connecting ring 701, and each triangular driving block 806 is arranged at intervals corresponding to each anti-reversal plate 705, and the cross section of the triangular driving block 806 is a right triangle, and the inclined surface of the triangular driving block 806 is consistent with the inclination direction of the anti-reversal plate 705;

[0054] Specifically, when the third shaft rod 805 rotates forward due to the opening of the second closed door 4, the right-angled side of the triangular driving block 806 can push against one side of the anti-reversal plate 705 to move, and the movement of the anti-reversal plate 705 can control the exhaust assembly 7 to rotate as a whole. When the third shaft rod 805 rotates reversely due to the closing of the second closed door 4, the exhaust assembly 7 can continue to rotate forward under the action of inertia, and the inclined surface of the triangular driving block 806 can move along the side wall of the anti-reversal plate 705. The end of the anti-reversal plate 705 away from the connecting ring 701 can produce a slight movement according to the reverse movement of the triangular driving block 806, thereby preventing the exhaust assembly 7 from following the third shaft rod 805 to rotate reversely, so as to ensure the exhaust position of the exhaust assembly 7.

A strong spring 11 is arranged inside the arc-shaped mounting tube 9, and one end of the strong spring 11 is elastically connected to one end of the arc-shaped support bar 10. The elastic force of the strong spring 11 can control the arc-shaped support bar 10 to support the first rectangular plate 301, so that the first rectangular plate 301 can remain in a closed state. When a person opens the first rectangular plate 301, the movement of the first rectangular plate 301 can control the arc-shaped support bar 10 to squeeze the strong spring 11 to contract and move along the inner wall of the arc-shaped mounting tube 9.

[0057] Example 3

[0058] This embodiment is an improvement made on the basis of embodiment 1. Figure 1 , Figure 2 and Fig.11As shown, one side of the transfer box 101 is provided with an installation port 12 connected to the exhaust chamber 106, and the interior of the installation port 12 is provided with a storage net box 13, and the interior of the storage net box 13 is provided with activated carbon adsorption particles 14.

[0059] The implementation principle of the transfer type pre-recovery device for medical care waste in the embodiment of the present invention is:

[0060] When in use, personnel put the garbage bag containing medical care waste into the pre-recovery box 1 through the first closed door 3. When the first closed door 3 is opened, the transmission gear 6 controls the limit assembly 5 to move to the side away from the first closed door 3, so that the end of the limit assembly 5 away from the first closed door 3 can be moved down to the side of the second closed door 4 away from the first closed door 3, so that the bottom of the second closed door 4 and the waste guide plate 2 can be controlled to remain in a closed state, so as to prevent harmful gases in the pre-recovery box 1 from entering between the first closed door 3 and the second closed door 4 through the second closed door 4. After the waste enters the pre-recovery box 1, the first closed door 3 can be closed. The thrown waste slides along the waste guide plate 2 to the second closed door 4, and the second closed door 4 can be opened under the action of the gravity of the waste. The opening movement of the second closed door 4 cooperates with the transmission component 8 to control the operation of the exhaust component 7. The operation of the exhaust component 7 can control the air inside the pre-recovery box 1 to circulate toward the designated part, thereby preventing the air inside the pre-recovery box 1 from being discharged outwardly and directly toward the face of the person throwing the waste into the pre-recovery box 1 during the process of the person throwing the waste into the pre-recovery box 1. At the same time, it can prevent the person throwing the waste from inhaling harmful gases, thereby improving the safety of the people using the present application.

[0061] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
