Technical Field
[0001] This utility model relates to a sealing and disinfection device, and more particularly to a sputum bag sealing and disinfection device. Background Technology
[0002] When a patient has phlegm, the current procedure is for the patient to wrap the coughed-up material with toilet paper after coughing, place the toilet paper in a sputum bag, and then manually tie the sputum bag closed. When coughing up phlegm again, the sputum bag needs to be opened, and the toilet paper containing the coughed-up material needs to be put into the sputum bag. When the sputum bag is almost full, the medical staff will change the sputum bag for the patient.
[0003] Due to some patients' lack of hygiene awareness, the following problems exist in practice: patients place toilet paper in the sputum bag but do not tie the bag tightly, or leave the bag opening directly exposed to the air. This can cause germs in the sputum to spread through the air, affecting the health of medical staff and patients' families. Utility Model Content
[0004] The purpose of this invention is to provide a sputum bag sealing and disinfection device to solve the technical problems in the prior art. It can effectively seal the sputum bag to prevent bacteria from spreading through the air, and it also has a disinfection function that can actively kill bacteria.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] Embodiments of this utility model: such as Figures 1-3 As shown, a sputum bag sealing and disinfection device includes a bag opening fixing ring, on which a disinfection component is provided. The bag opening fixing ring includes a first semicircular ring 1, a second semicircular ring 2, and a hinge 3. The two ends of the first semicircular ring 1 are respectively hinged to the two ends of the second semicircular ring 2 through the hinge 3. The bag opening of the sputum bag is connected to the first semicircular ring 1 and the second semicircular ring 2. A first magnet 4 is fixed on the top surface of the first semicircular ring 1, and a second magnet 5 is fixed on the top surface of the second semicircular ring 2.
[0020] The first semicircular ring 1 and the second semicircular ring 2 are preferably made of plastic to reduce production costs. The inner and outer diameters of the first semicircular ring 1 and the second semicircular ring 2 are the same. When unfolded, the first semicircular ring 1 and the second semicircular ring 2 form a complete ring shape; when folded, they seal the opening of the sputum bag.
[0021] The first magnet 4 and the second magnet 5 are sheet magnets. The first magnet 4 can be attached to the top surface of the first semi-circular ring 1, and the second magnet 5 can be attached to the top surface of the second semi-circular ring 2. When the first magnet 4 and the second magnet 5 are attracted together, the opening of the sputum bag is sealed.
[0022] In one specific embodiment, a first mounting groove 6 is formed at the bottom of the first semicircular ring 1, and a first rubber strip 7 is installed in the first mounting groove 6. A second mounting groove 8 is formed at the bottom of the second semicircular ring 2, and a second rubber strip 9 is installed in the second mounting groove 8.
[0023] The design of the first mounting groove 6, the first rubber strip 7, the second mounting groove 8, and the second rubber strip 9 allows for quick fixation of the sputum bag opening to the first semicircular ring 1 and the second semicircular ring 2, while also facilitating separation, thus enabling the present application to be reused.
[0024] The width of the first rubber strip 7 is preferably 2mm larger than the width of the first mounting groove 6, so that the first rubber strip 7 is not easy to come loose after being installed in the first mounting groove 6. Similarly, the width of the second rubber strip 9 is preferably 2mm larger than the width of the second mounting groove 8.
[0025] To facilitate the disassembly of the first rubber strip 7 and the second rubber strip 9, multiple pull rings 10 are provided on the bottom surface of both the first rubber strip 7 and the second rubber strip 9.
[0026] Furthermore, a first handle 19 is fixedly provided in the middle of the outer peripheral wall of the first semicircular ring 1, and a second handle 11 is fixedly provided on the outer peripheral wall of the second semicircular ring 2. The second handle 11 is offset from the first handle 19.
[0027] When the first semicircular ring 1 and the second semicircular ring 2 are brought together, the attraction force between the first magnet 4 and the second magnet 5 is relatively large, making it inconvenient to separate the first semicircular ring 1 and the second semicircular ring 2. In order to facilitate the separation of the two and open the sputum bag, a first handle 19 and a second handle 11 are preferably provided. Since the two are arranged in a staggered manner, one hand can hold the first handle 19 and the other hand can hold the second handle 11 and apply force in opposite directions at the same time, so that the first magnet 4 and the second magnet 5 can be separated and the sputum bag can be opened.
[0028] The first handle 19 has a through hole 12. By having a through hole 12 on the first handle 19, this application can be easily hung on a hook on the side of the hospital bed for easy access when needed.
[0029] Furthermore, the disinfection component is an existing product that can be directly purchased. In this embodiment, the disinfection component includes a sealing cap 13, a nozzle assembly 14, a pressure handle 15, a liquid outlet tube, and a bottle body 16. The nozzle assembly 14 is fixed to the sealing cap 13, the pressure handle 15 is installed on the nozzle assembly 14, the bottle body 16 is threaded to the sealing cap 13, one end of the liquid outlet tube is connected to the nozzle assembly 14, and the nozzle assembly 14 has a spray tube 17 at its spray nozzle, which passes through the second semi-circular ring 2. A rotating shaft 18 is rotatably mounted on the outer wall of the first semi-circular ring 1, and one end of the rotating shaft 18 is fixedly connected to the sealing cap 13.
[0030] It should be noted that the nozzle assembly 14 is existing technology, therefore its internal structure will not be described in detail in this embodiment. Since the dispensing tube is located inside the bottle body 16, it is not shown in the figure. By repeatedly pressing the handle 15, the handle 15 drives the nozzle assembly 14 to pump air into the bottle body 16. The increased air pressure inside the bottle body 16 forces the medicine through the dispensing tube into the nozzle assembly 14 and out through the spray nozzle. The medicine then passes through the spray tube 17 and is finally sprayed into the sputum bag, achieving sterilization and disinfection.
[0031] Preferably, hinge 3 is a spring hinge. Spring hinges are commercially available and have a torsion spring. When the first semicircular ring 1 and the second semicircular ring 2 are in the unfolded state, releasing the first handle 19 or the second handle 11 causes the first semicircular ring 1 and the second semicircular ring 2 to automatically close under the action of the torsion spring on the spring hinge, so that the first magnet 4 and the second magnet 5 are attracted together to achieve automatic closure of the sputum bag opening.
[0032] The working principle of this utility model is as follows: When in use, the opening end of the sputum bag is inserted into the first mounting groove 6 and the second mounting groove 8, then the first rubber strip 7 is inserted into the first mounting groove 6, and the second rubber strip 9 is inserted into the second mounting groove 8. In this way, the opening of the sputum bag is fixed on the first semi-circular ring 1 and the second semi-circular ring 2.
[0033] One hand holds the first handle 19, and the other hand holds the second handle 11, unfolding the first semicircular ring 1 and the second semicircular ring 2 to... Figure 1 In the indicated state, the sputum bag opening is open, allowing the insertion of tissue paper containing coughed-up material. Then, the first semi-circular ring 1 and the second semi-circular ring 2 are closed. It should be noted that when using a regular hinge, the two parts need to be manually closed. When using a spring hinge, releasing the first handle 19 or the second handle 11 causes the first semi-circular ring 1 and the second semi-circular ring 2 to automatically close under the action of the torsion spring on the spring hinge. After closing, as shown... Figure 2 As shown, the first magnet 4 and the second magnet 5 are magnetically attracted together, and the opening of the sputum bag is sealed. Viruses and bacteria cannot be transmitted through the air.
[0034] With the sputum bag sealed, pressing the handle 15 several times and spraying disinfectant into the bag will kill any viruses and bacteria inside, eliminating concerns about virus and bacteria transmission when opening the bag next time. When not in use, the first handle 19 can be hung on a hook beside the bed through the through-hole 12 for easy access.
[0035] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
