Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more specifically to a dressing changing device for breast and thyroid surgery care. Background Art

[0002] The thyroid gland and mammary gland are both important endocrine glands, each of which secretes different hormones and plays a key role in the body's metabolism, growth and development. Thyroid hormones can affect the metabolism of estrogen and prolactin, and the normality of the mammary gland is closely related to the levels of estrogen and prolactin in the body.

[0003] After breast and thyroid surgery, patients need to be cared for and given dressings, including checking wounds, removing pus and secretions, cleaning wounds and covering dressings. Nursing and dressing changes are important surgical operations to prevent and control wound infection, eliminate factors that hinder wound healing and promote wound healing. Currently, most breast and thyroid surgery nursing dressing change devices lack waste disposal devices, so that the waste after dressing change can only be placed on the dressing change device. Since the dressing change device is frequently used, various medicines and instruments used for dressing change are placed on it during use, which can easily lead to cross infection and is not conducive to the patient's recovery.

[0004] In view of the above problems, some solutions have been provided in the prior art. For example, the Chinese utility model patent with announcement number CN215536013U discloses a dressing changing device for breast and thyroid surgical care. The device can seal the trash can through an arc plate, thereby preventing cross-infection of pollutants and other items to a certain extent; however, the prior art needs to open the arc plate during the storage of pollutants. At this time, the pollutants in the trash can will be directly exposed to the outside world, and then the bacteria on the pollutants will come into contact with the clean medicines on the surface of the workbench with the air, causing the clean medicines to be contaminated, which in turn affects the patient's wound infection and poses a safety hazard to the patient's health.

[0018] Furthermore, a roller for driving the collection block to move is provided on the bottom wall of the collection block, and a handrail is fixedly installed on the side wall of the collection block.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) This solution uses a partition. When the blocking plate is opened, the partition can separate the pollutants below the partition from the collection port. After the blocking plate is closed, the partition rotates downward and causes the pollutants above the partition to fall into the space below the collection chamber. After the pollutants fall into the collection chamber below the partition, the reset spring drives the partition to reset and seal the pollutants below the partition again, thereby effectively preventing the waste in the collection chamber from contacting the outside world through the air when the blocking plate is opened to throw in waste, thereby reducing the probability of cross-infection of waste and playing a role in reducing patient safety hazards;

[0021] (2) This solution opens an air cavity. After the reset pad contracts and drives the horizontal rod to reset, the gas in the air cavity flows into the disinfection cavity through the first control component, and the pressure in the disinfection cavity is increased. Then, under the action of the pressure, the disinfectant in the disinfection cavity flows into the disinfection cavity through the pressure valve and the disinfection tube, and the space above the partition in the collection cavity is disinfected through the disinfection hole on the disinfection cavity, further preventing the viruses and bacteria in the collection cavity from being cross-infected with other external drugs through the collection port. At the same time, the setting of the first control component can make the disinfection work after the partition and the sealing plate are both horizontal, which can improve the disinfection effect of the space between the partition and the sealing plate, thereby further reducing the safety risks of patients;

[0022] (3) In this scheme, a sealing gasket is set. During the upward movement of the partition, the gas pressure in the space above the partition in the installation groove increases and tends to flow to the outside through the third air pipe. During the upward rotation of the partition, the partition gradually contacts the sealing block and drives the sealing block to move upward. When the partition is in a horizontal state, the sealing block drives the connecting hole to contact the third air pipe. At this time, the gas in the space above the push plate in the installation groove flows into the cavity through the third air pipe, the connecting hole, and the second air pipe, and causes the sealing gasket to collide. Then, the colliding sealing gasket fits tightly with the side wall of the partition, thereby increasing the airtightness between the partition and the collection chamber, thereby further preventing the virus and bacteria under the partition from flowing to the outside through the gap between the partition and the collection chamber, and further reducing the safety risks of patients.

DETAILED DESCRIPTION

[0035] The technical solutions 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; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 10 , a dressing changing device for breast and thyroid surgery nursing, comprising a collecting block 1, the collecting block 1 is provided with a collecting chamber 2 for collecting pollutants, the top wall of the collecting chamber 2 is provided with a collecting port communicating with the outside, and the collecting chamber 2 is provided with a blocking component for blocking the collecting port;

[0037] The blocking component includes a blocking plate 301 rotatably mounted on the side wall of the collection port, a first magnet 302 is embedded in the blocking plate 301, a second magnet 303 mutually attracted to the first magnet 302 is embedded in the collection block 1, a partition 304 for secondary blocking of pollutants is rotatably mounted on the side wall of the collection chamber 2, and a return spring 305 is fixedly mounted between the rotating shaft of the partition 304 and the collection block 1, a first gear 306 and a second gear 307 are fixedly mounted on the rotating shafts of the blocking plate 301 and the partition 304, respectively, and a driving component for driving the blocking plate 301 and the partition 304 to open and close is provided on the collection block 1;

[0038] The driving assembly includes a vertical groove opened on the collecting block 1, in which a vertical rod 308 is slidably installed, a rack 309 cooperating with the first gear 306 is fixedly installed on the top wall of the vertical rod 308, and an inclined block 310 cooperating with the second gear 307 is provided on the vertical rod 308.

[0039] The vertical rod 308 is evenly provided with sliding grooves that cooperate with the inclined block 310, and a first spring 401 is fixedly installed between the side wall of the inclined block 310 and the sliding groove. A horizontal rod 402 is fixedly installed on the bottom wall of the vertical rod 308, and a reset pad 403 is fixedly installed between the top wall of the horizontal rod 402 and the collecting block 1. A pedal 404 is fixedly installed on the side wall of the horizontal rod 402, and a disinfection component that cooperates with the reset pad 403 is provided on the collecting block 1.

[0040] In the initial state, the reset spring 305 is in a freely extended state. When it is necessary to discard waste, the medical staff can first step on the pedal 404 with their feet, and then the pedal 404 drives the vertical rod 308 to move downward through the horizontal rod 402. At this time, the reset pad 403 is stretched and has a tendency to recover. In the process of the vertical rod 308 moving downward, the rack 309 is driven to move downward, and then the blocking plate 301 is driven to rotate around the rotation axis point through the first gear 306 during the process of the rack 309 moving downward, and the collection port is opened and closed. Then, the medical staff can throw the waste into the collection chamber 2, and the waste falls on the partition 304. The top wall of the vertical rod 308 is formed on the top wall of the vertical rod 308. At the same time, the inclined block 310 is driven to move downward in the process of the vertical rod 308 moving downward. In the process of the inclined block 310 passing the second gear 307, the reset spring 305 prevents the partition 304 from rotating around the rotating shaft. Then, when the inclined block 310 passes the second gear 307, the second gear 307 causes the inclined block 310 to squeeze the first spring 401 along the slide groove. When the inclined block 310 is out of contact with the second gear 307, the first spring 401 stretches and drives the inclined block 310 to reset. Then, after the waste is discarded, the reset pad 403 contracts and drives the horizontal rod 402 to move upward. During the upward movement, the rack 309 is driven to move upward by the vertical rod 308. During the upward movement of the rack 309, the blocking plate 301 is driven to rotate downward by the first gear 306 to block the collection port. When the side wall of the blocking plate 301 contacts the collection port, the rack 309 is disengaged from the first gear 306. Then, under the action of the first magnet 302 and the second magnet 303, the blocking plate 301 is fixed in the collection port. After the rack 309 is disengaged from the first gear 306, the blocking plate 301 blocks the collection port. At the same time, as the vertical rod 308 continues to move upward, it drives the inclined block 310 and the first gear 316 to rotate downward. The two gears 307 contact each other, and then the second gear 307 drives the partition 304 to rotate downward under the action of the inclined block 310. At this time, the reset spring 305 begins to accumulate force, and then the waste on the partition 304 falls along the top wall of the partition 304 to the bottom of the collecting chamber 2. When the inclined block 310 is out of contact with the second gear 307, the reset spring 305 drives the partition 304 to reset and seal the waste under the collecting chamber 2, thereby effectively preventing the waste in the collecting chamber 2 from contacting the outside world through the air when the sealing plate 301 is opened to throw in waste, thereby reducing the probability of cross-infection of waste and playing a role in reducing patient safety hazards.

[0041] like Figure 2 , Figure 3 , Figure 4As shown, the disinfection component includes a disinfection chamber 501 provided on the collection block 1, and the disinfection chamber 501 is filled with disinfectant, a disinfection groove 502 is provided on the collection block 1, and disinfection holes 503 connected to the collection chamber 2 are evenly provided on the side wall of the disinfection groove 502, a disinfection tube 504 extending into the disinfection chamber 501 is inserted on the side wall of the disinfection groove 502, and a pressure valve 505 whose input end is connected to the disinfection chamber 501 is fixedly installed at one end of the disinfection tube 504 away from the disinfection groove 502, an air cavity 506 is provided on the reset pad 403, and a first air inlet valve 507 whose input end is connected to the outside is inserted on the air cavity 506, and a first control component connecting the air cavity 506 with the disinfection chamber 501 is provided on the collection block 1.

[0042] The first control component includes a groove formed on the collecting block 1, in which a sealing rod 601 extending into the air cavity 506 is slidably installed, a second spring 602 is fixedly installed between the top wall of the sealing rod 601 and the groove, an air groove 603 is formed on the sealing rod 601, a first air pipe 604 connected to the disinfection cavity 501 is inserted in the groove, and an end of the first air pipe 604 away from the groove is located above the liquid level of the disinfectant.

[0043] By adopting the above technical solution, the reset pad 403 is stretched during the downward movement of the horizontal rod 402, and at this time, the air cavity 506 inhales air through the first air inlet valve 507, and then during the upward movement of the reset pad 403, the gas in the air cavity 506 flows into the disinfection cavity 501 through the first control component, and the pressure in the disinfection cavity 501 increases, and then under the action of pressure, the disinfectant in the disinfection cavity 501 flows into the disinfection cavity 501 through the pressure valve 505 and the disinfection tube 504, and the space above the partition 304 in the collection cavity 2 is disinfected through the disinfection hole 503 on the disinfection cavity 501, further preventing the virus and bacteria in the collection cavity 2 from cross-infection with other external drugs through the collection port, and further reducing the safety risks of patients.

[0044] By setting the first control component, in the process of the reset pad 403 driving the horizontal rod 402 to move upward, it will gradually contact the sealing rod 601 and drive the sealing rod 601 to move upward. At this time, the second spring 602 is compressed and has a tendency to recover. After the vertical rod 308 is reset, the sealing plate 301 and the partition 304 are both in a horizontal state. The sealing rod 601 drives the air groove 603 to contact the first air pipe 604. At this time, the gas in the air cavity 506 can flow to the disinfection chamber 501 through the first air pipe 604, and drive the disinfectant in the disinfection chamber 501 to disinfect the collection chamber 2 above the partition 304. By performing disinfection after the partition 304 and the sealing plate 301 are both in a horizontal state, the disinfection effect of the space between the partition 304 and the sealing plate 301 can be improved, thereby improving the disinfection effect.

[0045] When the horizontal rod 402 stretches the reset pad 403 downward, the second spring 602 stretches and drives the sealing rod 601 to move downward. During the downward movement of the sealing rod 601, the air groove 603 is driven to break contact with the first air pipe 604, thereby preparing for disinfection again.

[0046] like Figure 2 , Figure 4 , Figure 5 As shown, a mounting block 701 is fixedly installed on the side wall of the collecting chamber 2, a mounting groove 703 is opened on the mounting block 701, a T-shaped push plate 702 is vertically slidably installed in the mounting groove 703, and a third spring 704 is fixedly installed between the top wall of the push plate 702 and the mounting groove 703.

[0047] The collecting block 1 is embedded with a C-shaped sealing gasket 801 that cooperates with the partition 304, and the sealing gasket 801 is provided with a cavity 802, and the cavity 802 is inserted with a second air pipe 803 that cooperates with the mounting groove 703, and the collecting block 1 is provided with a second control component that cooperates with the second air pipe 803.

[0048] The second control component includes a linkage groove opened on the collecting block 1, a sealing block 804 is slidably installed in the linkage groove, and a fourth spring 805 is fixedly installed between the top wall of the sealing block 804 and the linkage groove, a connecting hole 806 cooperating with the second air pipe 803 is opened on the sealing block 804, a third air pipe 807 connected to the installation groove 703 is inserted on the side wall of the linkage groove, and a second air intake valve 808 whose input end is connected to the outside is inserted on the side wall of the installation groove 703.

[0049] The sealing block 804 is provided with a pressure relief groove 9 which cooperates with the first air pipe 604 .

[0050] By adopting the above technical solution, during the downward rotation of the partition 304, the third spring 704 stretches and drives the push plate 702 to move downward. During the downward movement of the push plate 702, it gradually contacts the pollutants on the top wall of the partition 304, and drives the pollutants along the partition 304 to fall into the space below the collection chamber 2. Then, when the partition 304 rotates upward, it drives the push plate 702 to move upward and squeeze the third spring 704, thereby ensuring that the pollutants enter the space below the collection chamber 2 normally.

[0051] During the downward movement of the partition 304, the space above the push plate 702 in the installation groove 703 inhales air through the second air inlet valve 808, and gradually loses contact with the sealing block 804 during the downward rotation of the partition 304. At this time, the fourth spring 805 stretches and drives the sealing block 804 to move downward, and drives the connecting hole 806 to lose contact with the third air pipe 807 during the downward movement of the sealing block 804. Then, during the upward movement of the partition 304, the gas pressure in the space above the partition 304 in the installation groove 703 increases and tends to flow to the outside through the third air pipe 807. During the upward rotation of the partition 304, the partition 304 gradually contacts the sealing block 804. The sealing block 804 is touched and drives the sealing block 804 to move upward, and when the partition 304 is in a horizontal state, the sealing block 804 drives the connecting hole 806 to contact the third air pipe 807. At this time, the gas in the space above the push plate 702 in the installation groove 703 flows into the cavity 802 through the third air pipe 807, the connecting hole 806, and the second air pipe 803, and causes the sealing gasket 801 to collide, and then the colliding sealing gasket 801 fits tightly with the side wall of the partition 304, thereby increasing the airtightness between the partition 304 and the collection chamber 2, thereby further preventing the virus and bacteria under the partition 304 from flowing to the outside through the gap between the partition 304 and the collection chamber 2, and further reducing the safety risks of patients.

[0052] When the partition 304 rotates downward, the fourth spring 805 drives the pressure relief groove 9 to contact the outside through the sealing block 804. At this time, the gas in the cavity 802 flows to the outside through the second air pipe 803 and the pressure relief groove 9, and then the sealing gasket 801 gradually shrinks and resets. Therefore, in the process of the partition 304 rotating upward, the sealing gasket 801 can be prevented from affecting the reset of the partition 304, thereby ensuring the normal reset of the partition 304.

[0053] like Figure 1 As shown, a placement rack 10 for placing clean medicines is fixedly mounted on the side wall of the collecting block 1, and a cleaning opening is opened on the side wall of the collecting chamber 2, and a cabinet door 11 is hinged in the cleaning opening.

[0054] By adopting the above technical solution, when in use, medical staff can place clean medicines to be used on the placement rack 10, and when there is too much waste in the collection chamber 2, the cleaning staff can first open the cabinet door 11, and then the cleaning staff can take out the waste through the cleaning port, which improves the convenience of the device.

[0055] like Figure 1 As shown, a roller 12 for driving the collection block 1 to move is provided on the bottom wall of the collection block 1 , and a handrail 13 is fixedly installed on the side wall of the collection block 1 .

[0056] By adopting the above technical solution, during the process of medical staff changing dressings, the medical staff can use the handrail 13 to push the collection block 1 to roll on the ground through the roller 12, and move the device to the patient, which makes it easier for medical staff to change dressings.

[0057] Instructions for use: When it is necessary to discard waste, the medical staff can first step on the pedal 404 with their feet, and then the pedal 404 drives the vertical rod 308 to move downward through the horizontal rod 402. At this time, the reset pad 403 is stretched and has a tendency to recover. In the process of the vertical rod 308 moving downward, the rack 309 is driven to move downward, and then the blocking plate 301 is driven to rotate around the rotation axis point through the first gear 306 during the process of the rack 309 moving downward, and the collection port is opened and closed. Then the medical staff can throw the waste into the collection chamber 2, and the waste falls on the top wall of the partition 304. At the same time, in the process of the vertical rod 308 moving downward, the inclined block 310 is driven to move downward. When the waste is discarded, the reset pad 403 contracts and drives the horizontal rod 402 to move upward. When the horizontal rod 402 moves upward, the rack 309 is driven upward by the vertical rod 308. When the rack 309 moves upward, the blocking plate 301 is driven downward by the first gear 306 to rotate, and the collecting port is closed. The blocking plate 301 is sealed, and when the side wall of the blocking plate 301 contacts the collecting port, the rack 309 disengages from the first gear 306, and then the blocking plate 301 is fixed in the collecting port under the action of the first magnet 302 and the second magnet 303; after the rack 309 disengages from the first gear 306, the blocking plate 301 blocks the collecting port, and at the same time, as the vertical rod 308 continues to move upward, the inclined block 310 is driven to contact the second gear 307, and then the second gear 307 drives the partition 304 to rotate downward under the action of the inclined block 310. At this time, the reset spring 305 begins to accumulate force, and then the waste on the partition 304 falls along the top wall of the partition 304 to the bottom of the collecting chamber 2. When the inclined block 310 and the second gear 307 are When the wheel 307 is out of contact, the reset spring 305 drives the partition 304 to reset and seal the waste below the collection chamber 2; the reset pad 403 is stretched during the downward movement of the horizontal rod 402, and the air cavity 506 inhales air through the first air inlet valve 507. Then, during the upward movement of the reset pad 403, the gas in the air cavity 506 flows into the disinfection chamber 501 through the first control component, and the pressure in the disinfection chamber 501 is increased. Then, under the action of the pressure, the disinfectant in the disinfection chamber 501 flows into the disinfection chamber 501 through the pressure valve 505 and the disinfection tube 504, and the space above the partition 304 in the collection chamber 2 is disinfected through the disinfection hole 503 on the disinfection chamber 501.During the downward movement of the partition 304, the space above the push plate 702 in the installation groove 703 inhales air through the second air inlet valve 808, and gradually loses contact with the sealing block 804 during the downward rotation of the partition 304. At this time, the fourth spring 805 stretches and drives the sealing block 804 to move downward, and drives the connecting hole 806 to lose contact with the third air pipe 807 during the downward movement of the sealing block 804. Then, during the upward movement of the partition 304, the gas pressure in the space above the partition 304 in the installation groove 703 increases and tends to flow to the outside through the third air pipe 807. During the upward rotation of the partition 304, the partition 304 gradually contacts the sealing block 804 and drives the sealing block 804 to move upward. When the partition 304 is in a horizontal state, the sealing block 804 drives the connecting hole 806 to contact the third air pipe 807. At this time, the gas in the space above the push plate 702 in the installation groove 703 flows into the cavity 802 through the third air pipe 807, the connecting hole 806, and the second air pipe 803, and causes the sealing gasket 801 to collide. Then, the colliding sealing gasket 801 is closely attached to the side wall of the partition 304, thereby increasing the airtightness between the partition 304 and the collecting chamber 2. ;
