Description

Technical Field

[0001] This invention relates to the technical field of medical device accessories, and in particular to an outpatient nursing dressing change device. Background Technology

[0002] In the surgical outpatient clinic, we often receive patients who need to undergo procedures such as disinfection, dressing changes, and burn treatment. Surgical nursing often requires the use of nursing medications and instruments such as forceps, scissors, scalpels, gauze, and sterile cotton.

[0003] When treating a patient's wound, blood or used medications are often produced, along with gauze and medical cotton. In current technology, these items are usually thrown directly into the trash can. While convenient, the medical cotton and gauze soaked in the medication and blood cannot be sorted, making subsequent processing difficult. Furthermore, because there is no dedicated cleaning equipment, waste liquids from cleaning and disinfection are spilled on the bed or floor during collection, easily causing environmental pollution.

[0004] The files retrieved so far are:

[0005] 1. CN211105785U discloses an operating room collection and care device, relating to the field of medical equipment technology. The device includes a box body, a lid rotatably connected to one side of the top of the box body, and multiple casters installed at the bottom. An inlet is opened in the middle of the lid, and a valve is installed on the inlet. A shelf is slidably connected to the inner wall of the box body. A telescopic cylinder is fixedly connected to one side of the box body, and a squeezing plate is fixedly connected to the output end of the telescopic cylinder. When care waste is placed into the box body through the inlet, solid waste is retained on the shelf, while liquid waste enters the collection tank through a connecting pipe equipped with a filter screen, achieving separation of solid and liquid waste. This facilitates separate treatment of the two types of waste later and avoids the situation where liquid waste drips everywhere when treating solid waste without separation.

[0006] 2. CN212016038U discloses a medical outpatient nursing dressing change device, including a box body. A storage chamber is located on the upper left side of the box body, and a door is located on the left side of the storage chamber. A connector is fixedly connected to the middle of the storage chamber, and the right end of the connector extends into the interior of a waste fluid collection tank. A locking block is fixedly connected to the bottom right side of the storage chamber, and a collector is engaged inside the locking block. A filter screen is fixedly connected to the middle of the waste fluid collection tank, located below the connector. This invention uses a spray gun and a collector to evenly spray cleaning fluid onto the patient's wound, thereby quickly disinfecting and cleaning the wound. Simultaneously, the collector is positioned below the cleaning area to facilitate waste collection, avoiding pollution caused by waste and ensuring a stable and efficient dressing change process. This improves the dressing change efficiency of the device and enhances its rationality and feasibility.

[0007] 3. CN215538796U discloses a leachate treatment device with self-cleaning function, including a first motor, a hose, a bidirectional threaded rod, an electric cylinder, stirring blades, a filter screen, and a nozzle. The bidirectional threaded rod is rotated by the rotating end of the second motor. The first connecting block and the second connecting block are respectively connected to the right-hand thread and the left-hand thread on the bidirectional threaded rod. The rotation of the bidirectional threaded rod causes the first connecting block and the second connecting block to move closer together, which in turn drives the first hinge rod and the second hinge rod to move the first slider and the second slider closer together. The first slider slides along the first slide rail, and the second slider slides along the second slide rail, which causes the pressure plate to move downward to squeeze the garbage, so that the leachate in the garbage can flow out more fully. The rotation of the rotating end of the first motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the stirring blade to rotate. The stirring blade stirs and mixes the flocculant and the leachate.

[0008] Although the above-mentioned device discloses a separation mechanism for medical cotton or gauze from medication and blood, it has obvious drawbacks, such as complex operation, cumbersome steps, and inability to be automated. This causes inconvenience to users, hinders processing, affects the efficiency of dressing changes, and fails to achieve any positive effect. Summary of the Invention

[0048] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] like Figure 1 , 2 As shown in Figures 3, 4, 7, 8, and 11, an outpatient nursing dressing change device of the present invention includes:

[0051] Box 1 is hollow inside and has openings on its side walls. The top of box 1 is connected to inlet 2.

[0052] Inside the housing 1, there is a holding tank 3 located directly below the inlet 2. The waste inlet end of the holding tank 3 is rotatably mounted with a ring 4 via a pin. A filter screen 5 is fixed inside the ring 4. The holding tank 3 is connected to a valve that extends to the outside of the housing 1.

[0053] A connecting rod is fixed inside the housing 1. A rotating shaft 6 is rotatably mounted on the connecting rod. A pressure plate 7 is fixed on the rotating shaft 6. A protrusion 8 for squeezing the filter screen 5 is provided on the pressure plate 7.

[0054] In this embodiment, during use, the user cleans at the inlet 2. The blood and medicine generated during the cleaning process flow along the inlet 2 and through the filter screen 5 into the holding tank 3. The used medical cotton or bandage is intercepted and adhered to the filter screen 5. The valve outside the box 1 is opened periodically to allow the liquid inside the holding tank 3 to flow out. The protrusion 8 and the rotating shaft 6 are rotated periodically to squeeze the medical cotton and bandage, separating the solid and liquid, making it easier to recycle the medical cotton and bandage. After squeezing, the pin, ring 4 and filter screen 5 are rotated to remove the medical cotton and bandage from the filter screen 5.

[0055] As a preferred embodiment of the above, such as Figure 4 , 5 As shown in 6, 7, 8, 10 and 11, a fixing plate 9 is fixed inside the box body 1 by the support legs. An annular groove 10 is opened on the fixing plate 9. A connecting groove 11 is opened on both sides of the annular groove 10. The two connecting grooves 11 and the annular groove 10 form an "eye" shaped groove.

[0056] The sliding shaft 12 is guided by the "eye"-shaped groove formed by the annular groove 10 and the two connecting grooves 11, so that the rack 15 and other components can move along the rectangular track under the unidirectional rotation of the motor 16, thereby driving the protrusion 8 and the holding bucket 3 to move in turn.

[0057] Two sliding shafts 12 are slidably installed in the "eye"-shaped groove. A connecting plate 13 is fixed to the two sliding shafts 12, and a drive shaft 14 is fixed to the connecting plate 13. A rack 15 is fixed to the other end of the drive shaft 14. Figure 12 As shown;

[0058] A motor 16 is fixed on the fixed plate 9. A drive arm 17 is fixed on the output shaft of the motor 16. An elongated hole is opened on the drive arm 17, and the drive shaft 14 passes through the elongated hole.

[0059] Inside the housing 1, there is a connecting rod 2. A central shaft 18 is rotatably mounted on the connecting rod 2. A gear 19 is fixed on the central shaft 18. A rack 15 meshes with the gear 19. A reciprocating shaft 20 is fixed on the edge area of ​​the gear 19.

[0060] A track 21 is fixed on the fixed plate 9. A reciprocating block 22 is slidably installed on the track 21. An elongated hole 2 is opened on the reciprocating block 22. The end of the reciprocating shaft 20 extends into the elongated hole 2.

[0061] A push shaft 23 is fixed on the reciprocating block 22, and a swing arm 24 is fixed on the pressure plate 7. An elongated hole 3 is opened on the swing arm 24, and the end of the push shaft 23 extends into the elongated hole 3.

[0062] With the above settings, during the meshing process between the rack 15 and the gear 19, the gear 19 rotates 360°, and the reciprocating shaft 20 and other components return to their initial positions. Since the reciprocating shaft 20 is fixed on the edge area of ​​the gear 19, the reciprocating block 22, the push shaft 23 and other components move along the track 21 and return to their initial positions. Since the push shaft 23 extends into the elongated hole 3 of the swing arm 24, the rotating shaft 6, the pressure plate 7 and the protrusion 8 swing at a certain angle and return to their initial state.

[0063] In this embodiment, when the motor 16 operates once, the output shaft of the motor 16 and the drive arm 17 rotate 360°, as shown in the figure. Since the drive shaft 14 passes through the elongated hole on the drive arm 17, during the rotation of the drive arm 17, the two sliding shafts 12 move along the rear end of the annular groove 10, causing the drive shaft 14, connecting plate 13, rack 15, and sliding shafts 12 to translate. Since the rack 15 meshes with gear 19, gear 19, central shaft 18, and reciprocating shaft 20 all rotate. When one of the sliding shafts 12 moves to the corner of the annular groove 10, the other sliding shaft 12 moves to the connection point between the connecting groove 11 and the annular groove 10. The continuing rotation of the drive arm 17 causes the drive shaft 14, connecting plate 13, sliding shaft 12, and rack 15 to move forward. Gear 19 disengages from rack 15, and rack 15 causes gear 19 to rotate during the above process. After rotating 360°, components such as the reciprocating shaft 20 returned to their initial positions. Since the reciprocating shaft 20 is fixed on the edge area of ​​the gear 19, the reciprocating block 22, the push shaft 23, etc., were displaced along the track 21 and returned to their initial positions. Since the push shaft 23 extends into the elongated hole 3 of the swing arm 24, the rotating shaft 6, the pressure plate 7, and the protrusion 8 swung at a certain angle and returned to their initial state. The protrusion 8 squeezes the medical cotton and bandages on the filter screen 5 to separate the solid and liquid. The liquid flows to the bottom of the container 3. In summary, when the motor 16 is powered on and rotates, it can automatically move the rack 15 along the rectangular track. During the movement, the rack 15 can first drive the protrusion 8 to swing, and then drive the container to swing. Without complicated control programs, the squeezing of medical cotton or bandages and the tilting of the container 3 can be completed, which is very convenient to use.

[0064] As a preferred embodiment of the above, such as Figure 4 , 5 As shown in Figures 6, 7, 8 and 12, a connecting rod 3 is fixed inside the housing 1, a central shaft 25 is rotatably mounted on the connecting rod 3, and a gear 26 and a sprocket 1 27 are fixed on the central shaft 25.

[0065] A connecting rod four is fixed on the fixed plate 9. A central shaft three 28 is rotatably mounted on the connecting rod four. A sprocket two 29 is fixed on the central shaft three 28. A chain 30 is fitted on the sprocket two 29 and the sprocket one 27.

[0066] A circular plate 31 is also fixed on the central shaft 3 28, and a reciprocating shaft 2 32 is fixed on the edge area of ​​the circular plate 31;

[0067] A second track 33 is fixed on the fixed plate 9. A second reciprocating block 34 slides on the second track 33. An elongated hole 4 is opened on the second reciprocating block 34. The other end of the second reciprocating shaft 32 extends into the elongated hole 4.

[0068] The reciprocating block is also provided with an elongated hole five. A swing arm two 35 is fixed to one end of the rotating shaft 6. A push shaft two 36 is fixed to the swing arm two 35. The other end of the push shaft two 36 extends into the elongated hole five.

[0069] In this embodiment, the rack 15 moves forward. When the two sliding shafts 12 are respectively located at the corner of the annular groove 10 and the connection point between the connecting groove 11 and the annular groove 10, the continuously rotating drive arm 17 causes the rack 15 to move to the left along the other end of the annular groove 10. The rack 15 meshes with the second gear 26. The moving rack 15 causes the second gear 26, the second central shaft 25, and the first sprocket 27 to rotate. When the two sliding shafts 12 are respectively located at the corner of the annular groove 10 and the connection point between the connecting groove 11 and the annular groove 10, the continuously rotating drive arm 17 causes the sliding shafts 12, the connecting plate 13, and the drive shaft 14 to move backward. When the rack 15 separates from the gear 26, the gear 26 rotates 360° under the drive of the rack 15. With the cooperation of the chain 30, the sprocket 29, the central shaft 38, the circular plate 31 and the reciprocating shaft 22 all rotate. Since the reciprocating shaft 22 is fixed on the edge area of ​​the circular plate 31, the rotating reciprocating shaft 22 causes the reciprocating block 24 to move a certain distance along the track 23 and then return to its initial position. Since the push shaft 26 fixed at the end of the swing arm 25 extends into the long hole 5, the pin and the filter screen 5 rotate a certain angle and then return to their initial state, so that the squeezed medical cotton and bandage are separated from the filter screen 5.

[0070] After the output shaft of motor 16 has rotated 360°, it will be in the position shown in the figure. To perform the next cleaning, simply turn on motor 16 and rotate the output shaft of motor 16 360°.

[0071] As a preferred embodiment of the above, such as Figure 7 , 9 As shown in Figure 10, a door 37 is rotatably installed at the opening, a half ring 38 is fixed inside the box body 1, a retaining ring 39 is slidably installed inside the box body 1, a transition rod 40 is fixed on the other end of the retaining ring 39, a triangular plate 41 is fixed on the other end of the transition rod 40, and a through hole is opened on the box body 1 for the triangular plate 41 to extend out.

[0072] A drive rod 42 is rotatably mounted on the door 37, and a drive block 43 is rotatably mounted on the other end of the drive rod 42. A track 3 44 is fixed inside the box body 1, and the drive block 43 slides with the track 3 44.

[0074] Inside the housing 1 is a receiving bucket 47, the receiving bucket 47 is positioned by a semi-ring 38 and a retaining ring 39, and a handle is movably installed on the receiving bucket 47;

[0075] In this embodiment, the medical masks and bandages that have been removed from the filter screen 5 fall into the receiving bucket 47 under the action of gravity. When it is necessary to clean the receiving bucket 47, the box door 37 is opened, and the drive block 43 slides along the track 3 44 under the pull of the drive rod 42.

[0076] During the sliding process of the drive block 43, it pushes the triangular plate 41, the transition rod 40 and the retaining ring 39 to move downwards. The return spring 46 is compressed. After the box door 37 is opened, the retaining ring 39 will not hinder the movement of the receiving bucket 47. Then, hold the handle and pull out the receiving bucket 47. When the box door 37 is closed, the drive block 43 moves in the opposite direction under the push of the drive rod 42. Under the elastic force of the return spring 46, the retaining ring 39 moves upwards to block the receiving bucket 47 and prevent it from shaking.

[0077] As a preferred embodiment of the above, such as Figure 2 , 10 As shown in Figure 11, the top of the box 1 is provided with several storage slots 48;

[0078] In this embodiment, the storage compartment 48 is a sunken type, which can hold different medicines and medical instruments, making it more convenient to use.

[0079] As a preferred embodiment of the above, such as Figure 2 As shown, the area around the inlet 2 is inverted cone shape;

[0080] In this embodiment, the inlet 2 is surrounded by an inverted cone shape, which helps the liquid flow through the inlet 2 and reduces environmental pollution.

[0081] As a preferred embodiment of the above, such as Figure 1 and 2 As shown, a handle 2 is installed on box 1, and casters are installed on box 1;

[0082] In this embodiment, the device is moved by holding handle two and using the casters, making it more convenient to use.

[0083] As a preferred embodiment of the above, such as Figure 8 As shown, filter 5 is hemispherical, and the protrusions 8 are made of rubber;

[0084] In this embodiment, the filter 5 is hemispherical, and the medical cotton and bandage can be concentrated at the bottom of the filter 5, which is more conducive to liquid separation and solid collection.

[0085] As a preferred embodiment of the above, such as Figure 12As shown, a support rod 49 is installed inside the housing 1 to support the pressure plate 7;
