Description

Technical Field

[0001] The present invention relates to the technical field of article transfer equipment, and in particular to an article transfer equipment used in an isolation room of an infectious department. Background Art

[0002] Infectious disease isolation rooms are facilities in hospitals or medical institutions that are specifically used to isolate and treat patients with infectious diseases. These isolation rooms are designed to prevent infectious diseases from spreading to other patients, visitors, and medical staff in the hospital, while providing a safe treatment environment and protecting medical staff from infection. The object transfer equipment in infectious disease isolation rooms generally refers to a device used to safely transfer objects, usually a sealed box or compartment, which can ensure that pathogens will not be leaked during the object transfer process through airtight seals and double door designs. Some transfer equipment can also be equipped with corresponding disinfection systems, etc., thereby reducing the risk of pathogen transmission when transferring objects, avoiding direct contact and transmission of pathogens, and avoiding direct contact between medical staff and patients, etc., causing cross-infection and pathogen transmission;

[0003] Although existing transfer equipment enables medical staff to have direct contact with patients, during the process of transferring items through the transfer equipment, patients or medical staff may open the doors at both ends of the equipment at the same time, which may cause the leakage of pathogens, resulting in cross-infection and transmission of pathogens.

[0004] In view of this, we propose an item transfer device for the isolation room of the infectious department. Summary of the invention

[0005] Technical issues solved

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides an item transfer device for the isolation room of the infectious department, which can effectively solve the problem in the prior art that patients or medical staff may open the doors at both ends of the device at the same time, causing leakage of pathogens, cross infection and transmission of pathogens.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] Embodiment: An article transfer device for an isolation room of an infectious department comprises a conveying cabin 1 for carrying out article transfer and delivery, a fixed box 2 is fixedly installed on one side of the conveying cabin 1, and a front sealing door 3 and a rear sealing door 5 are rotatably installed at both ends of the conveying cabin 1, a rotating shaft 8 is fixedly installed on one side of the front sealing door 3, one end of the rotating shaft 8 rotates through the fixed box 2 and extends to the inside of the fixed box 2, and a driving member for driving the front sealing door 3 to open and close is provided at one end of the rotating shaft 8 passing through the fixed box 2, and the driving member is arranged inside the fixed box 2;

[0029] Specifically, a conveying platform for conveying and delivering articles is provided in the conveying cabin 1. Medical staff can drive the rotating shaft 8 to rotate through the driving member provided inside the fixed box 2, thereby opening the front sealed door 3, and thus delivering the articles they need through the conveying platform in the conveying cabin 1 to the other end of the conveying cabin 1, and then reverse the rotating shaft 8 through the driving member, so as to close the front sealed door 3 again. Then, the patient can open the rear sealed door 5 installed at the other end of the conveying cabin 1 to take out his articles, and then close the rear sealed door 5. Conversely, when the patient needs to deliver the articles in his isolation room, he can first open the rear sealed door 5, and then open the front sealed door 3 after the rear sealed door 5 is closed.

[0030] Specifically, a positioning hole 16 is provided on one side of the rear sealing door 5 close to the fixing box 2, and an insertion rod 7 is provided inside the fixing box 2. One end of the insertion rod 7 close to the rear sealing door 5 movably passes through the fixing box 2. When the front sealing door 3 is opened by the driving member, the insertion rod 7 can be driven to be inserted into the positioning hole 16, and the rear sealing door 5 cannot be opened. When the rear sealing door 5 is opened, the positions of the positioning hole 16 and the insertion rod 7 are misaligned, that is, the front sealing door 3 cannot be opened by the driving member;

[0031] Specifically, when the front sealing door 3 is opened by the driving member, the driving member can drive the insertion rod 7 to be directly inserted into the positioning hole 16 provided in the rear sealing door 5, so that the rear sealing door 5 cannot rotate and cannot be opened accordingly. When the rear sealing door 5 is opened first, the rear sealing door 5 rotates, causing the positioning hole 16 and the insertion rod 7 to be misaligned. At this time, when the driving member is used to open the front sealing door 3 again, one end of the insertion rod 7 is abutted by one side of the rear sealing door 5, so that the driving member cannot drive the insertion rod 7 to move, and the front sealing door 3 cannot be opened at the same time.

[0032] Specifically, the driving member includes a worm wheel 13 fixedly mounted on one end of the rotating shaft 8 passing through the fixed box 2, the side of the worm wheel 13 away from the rotating shaft 8 is rotatably mounted on the inner cavity side wall of the fixed box 2, and the surface of the worm wheel 13 is also meshedly connected with a worm 12, and a fixed rod 9 is fixedly mounted on the inner cavity side wall of the worm 12, the top of the fixed rod 9 rotates through the fixed box 2, and the top of the fixed rod 9 is also fixedly mounted with a hand wheel 4;

[0033] Specifically, when the front sealing door 3 needs to be opened, the hand wheel 4 can be rotated forward, and the worm 12 fixedly installed on the surface of the fixing rod 9 can be driven to rotate, and the worm 12 can be used to drive the worm wheel 13 meshingly connected on the surface to rotate, and the worm wheel 13 can be used to drive the rotating shaft 8 to rotate, thereby driving the front sealing door 3 to rotate and open the front sealing door 3. Conversely, when the front sealing door 3 needs to be closed, the hand wheel 4 only needs to be rotated in the reverse direction.

[0034] Specifically, a first toothed pulley 11 is fixedly installed at the bottom of the fixed rod 9, and the bottom of the first toothed pulley 11 is rotatably installed at the bottom of the inner cavity of the fixed box 2. The surface of the first toothed pulley 11 is meshed and connected with a second toothed pulley 14 through a synchronous toothed belt 10. The top of the second toothed pulley 14 is rotatably installed at the top of the inner cavity of the fixed box 2. A gear 15 is fixedly installed at the bottom of the second toothed pulley 14. The surface of the gear 15 is meshed and connected to the surface of the insertion rod 7, and the surface of the insertion rod 7 is slidably connected to the limiting sleeve 6, and the bottom of the limiting sleeve 6 is fixedly installed at the bottom of the inner cavity of the fixed box 2.

[0035] Specifically, when the front sealing door 3 is opened, its fixing rod 9 rotates forwardly, thereby driving the first toothed belt wheel 11 fixed at the bottom to rotate, and synchronously driving the second toothed belt wheel 14 meshing with the synchronous toothed belt 10 to rotate, and at this time, the gear 15 can be driven to rotate, because the surface of the plug rod 7 is provided with a toothed groove, and the plug rod 7 is limited by the limiting sleeve 6, so that when the gear 15 rotates, the plug rod 7 can be driven to move forward, so as to be inserted into the positioning hole 16 of the rear sealing door 5, so that the rear sealing door 5 cannot rotate, thereby causing it to be unable to open, on the contrary, when the front sealing door 3 is closed, that is, the fixing rod 9 rotates in the opposite direction, the plug rod 7 can be moved out of the positioning hole 16, and when the front sealing door 3 is completely closed, the plug rod is completely moved out of the positioning hole 16, and at this time, the rear sealing door 5 can be opened;

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
