Description

Technical Field

[0001] The present invention relates to the field of postpartum care appliances, in particular to a disinfection device for an obstetric intensive care unit. Background Art

[0002] Regardless of whether the mother gives birth by vaginal delivery or cesarean section, a large amount of lochia will flow out within a few days after delivery. Although the maternity pad will be changed regularly and the mother's perineum will be cleaned, it is impossible to completely prevent blood from remaining in the mother's perineum due to the continuous flow of lochia. Under the action of the human body temperature, the blood attached to the mother's perineum will coagulate to form blood clots, which cannot be completely removed by direct flushing with a flusher. The commonly used method is that the nurse uses cotton balls, cotton towels and other soft items to wipe the mother's perineum while flushing. However, when cleaning, the distance between the nurse's hands and the cotton balls and cotton towels is too small, and the nurse may even need to hold the cotton towel in hand for scrubbing. At this time, the blood in the mother's perineum will penetrate the cotton balls or cotton towels and come into contact with the nurse. When the nurse has a wound on his hands, cross infection is likely to occur. Secondly, the nurse's too close touch will also cause some mothers to feel psychological discomfort, thereby affecting their mood.

[0003] Later, a gynecological genital cleaning brush appeared, as disclosed in the patent application number CN201811218742.6. A sponge is set up, and liquid is injected into the sponge using a piston to keep the sponge moist. At this time, the nurse can use a fixing device to fix the sponge. At this time, the nurse only needs to hold the outer shell structure of the cleaning brush to scrub the perineum with the sponge. The nurse's hands are at a large distance from the perineum of the parturient, which avoids cross infection and also prevents the nurse's hands from being too close to the perineum and causing discomfort to the parturient.

[0004] However, when the above-mentioned cleaning brush is used, if the sponge absorbs too much blood, the cleaning effect will be reduced, so the sponge needs to be replaced. Since the amount of lochia is large, in addition to the patient's perineum, the lochia will adhere to the buttocks, inner thighs and even the lower abdomen, resulting in a large area to be scrubbed. Therefore, the sponge needs to be constantly replaced during the scrubbing process, which is also inconvenient. Summary of the Invention

[0005] The present invention is intended to provide a disinfection device for an obstetric intensive care unit to solve the problem of constantly replacing sponges during scrubbing.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a disinfection device for an obstetric intensive care unit, comprising a flushing unit, a cleaning unit and a disinfection rod, the cleaning unit comprising a cleaning cover, a linear drive member and a power member, and a plurality of convex teeth are fixed to the inner wall of the cleaning cover; the disinfection rod comprises a head and a rod, the head is arranged at one end of the rod, and the head is located in the cleaning cover, one end of the cleaning cover is provided with an opening for the head to slide out, the rod passes through the end of the cleaning cover opposite to the opening and extends to the outside of the cleaning cover, the linear drive member is connected to the rod and is used to drive the head to slide out of the opening of the cleaning cover, and the rod can rotate relative to the cleaning cover; the power member is opposite to the rod and is used to drive the rod to rotate; the head is provided with a flexible cleaning layer, and the cleaning layer can contact the convex teeth, the cleaning cover is connected with a water outlet pipe and a water inlet pipe, and the water outlet pipe is opposite to the head; the flushing unit comprises a water inlet power member and a drainage power member, and the water inlet power member and the drainage power member are respectively connected to the water inlet pipe and the water outlet pipe.

[0007] The beneficial effects of this program are: The disinfection stick in this solution can replace traditional cotton balls or cotton towels to scrub the perineum of parturient women. Compared with cotton balls, the disinfection stick in this solution is larger in size and can cover a larger area of ​​skin when used, thereby improving scrubbing efficiency.

[0008] Secondly, the flushing and cleaning units provided in this solution allow the disinfection rod to be slid into the cleaning cover and cleaned. The cleaned disinfection rod can then be used to clean the perineum. After cleaning, the disinfection rod remains moistened. A small flow of water can then be applied to the skin by bringing the moistened disinfection rod into contact, transferring blood from the skin to the disinfection rod. The drainage power element then creates a negative pressure within the cleaning cover, drawing the blood and water from the clean layer into the cleaning cover and draining them through the outlet pipe, completing the perineal cleansing process. Compared to continuous flushing with a direct douche, this solution prevents large amounts of water from flowing through the perineum, potentially soaking the nursing pad beneath the mother while she lies flat on the bed. This water can then flow along the pad to the mother's back and other areas, soaking clothing on her back. It also prevents excessive water from overflowing from the pad, potentially soaking the sheets beneath it, due to insufficient pad capacity.

[0009] At the same time, when a mother gives birth naturally, most of the time she will undergo an episiotomy. At this time, there is often a wound on the perineum of the mother. If only a flusher is used to directly flush the perineum, a large amount of water will flow through the wound, causing pain in the wound. This solution uses scrubbing to clean, which can avoid excessive water flowing along the perineum of the mother to the wound location, so no pain will be caused.

[0010] Finally, during cleaning, the convex teeth in this solution come into contact with the cleaning layer to clean the cleaning layer, and the blood and blood scabs on the cleaning layer fall off, ensuring that the cleaned cleaning layer can better clean the perineum.

[0011] Furthermore, the end of the head away from the rod is a cleaning end, the surface of the cleaning end is an arc-shaped surface, and the cleaning layer is located between the cleaning end and the rod; the cleaning layer includes a plurality of flexible wires, which are distributed along the circumference of the head and are distributed in a manner such that one end is close to the head and the other end is away from the head.

[0012] The beneficial effects of this solution are: compared with sponges, the flexible silk in this solution is softer, and it is easier to clean blood when it enters the cleaning layer, and it is easier to keep dry after cleaning. Compared with cotton, the flexible silk in this solution does not fall off and is cleaner to use.

[0013] The curved surface of the cleaning end is not covered with flexible wire. When cleaning is required around the wound, the friction between the curved surface and the skin is smaller, thus avoiding secondary damage to the wound.

[0014] Furthermore, the diameter of the cleaning end near one end of the rod is larger than the diameter of the portion of the head corresponding to the cleaning layer, and is also larger than the inner diameter of the cleaning layer, forming a step between the cleaning end and the cleaning layer.

[0015] The beneficial effect of this solution is that the upward projection of the step covers the part where the flexible wire is connected to the head, thereby preventing the connection part from directly contacting the side wall of the opening during the process of sliding the head into the cleaning cover, which may cause the flexible wire to fall off or deform.

[0016] Furthermore, an end of the flexible wire away from the head is inclined toward a side close to the stem.

[0017] The beneficial effects of this solution are as follows: because the flexible wire is tilted, when the head is slid out of the opening, the flexible wire is first deformed toward the side closer to the head under the limiting effect of the opening, and then automatically resets after passing through the opening. At this time, the angle of deformation of the flexible wire is acute, so the force during reset is relatively small, which can prevent water attached to the flexible wire from being ejected during the reset process and splashing onto the bed, nursing pad, or patient's clothing and skin. After the head is slid into the cleaning cover, the flexible wire resets at a larger angle after passing through the opening, and the greater force can cause blood scabs attached to the flexible wire to fall off the flexible wire.

[0018] Furthermore, the lowermost protruding tooth is lower than the end of the lowermost flexible wire away from the head.

[0019] The beneficial effects of this solution are as follows: the convex teeth in this solution can better clean the flexible wire, and the plurality of convex teeth provided can comb the flexible wire during cleaning, further promoting the removal of blood scabs stuck inside the flexible wire, thereby improving the cleaning effect.

[0020] Furthermore, one end of the convex tooth away from the cleaning cover is inclined toward a side close to the connecting rod, and a water outlet hole connected to the water inlet pipe is provided on the convex tooth.

[0021] The beneficial effects of this solution are as follows: the convex teeth in this solution can better clean the flexible wire, and when the convex teeth are inserted into the cleaning layer, the ends of the convex teeth are closer to the connection between the flexible wire and the head, and the water flowing out from the water outlet can directly flush the connection part and make the water flow out from the root of the flexible wire, further improving the flushing effect of blood and blood scabs.

[0022] Furthermore, an annular sealing ring is fixed to the lower end of the cleaning cover, and the inner diameter of the sealing ring is smaller than the diameter of the largest part of the head.

[0023] The beneficial effect of this solution is that when the head enters the cleaning cover, the sealing ring and the head can be abutted against each other to seal the opening. At this time, a certain amount of water can be stored in the cleaning cover to soak and clean the head and the cleaning layer, further improving the cleaning effect of the flexible wire and avoiding a large amount of water dripping during cleaning.

[0024] Furthermore, a cavity that can be opened and sealed is provided in the head, and a cold storage liquid is stored in the cavity.

[0025] The beneficial effects of this solution are: by adding cold storage liquid to the head, the head can be kept at a low temperature. When the perineum of the parturient becomes red and swollen due to normal delivery, the cleaning end can apply ice to the red and swollen area when it comes into contact with the perineum, which is conducive to recovery of the redness and swelling.

[0026] Furthermore, an end of the head portion close to the rod portion is provided with a liquid inlet channel connected to the cavity, and the rod portion is detachably connected to the liquid inlet channel and is used to seal the liquid inlet channel.

[0027] The beneficial effects of this solution are: the cold storage liquid can be more conveniently added to the cavity and discharged from the cavity through the liquid inlet channel. The rod can be separated from the head, making it easier to replace the head, thereby keeping the cleaning layer clean.

[0028] Furthermore, the water inlet power component is connected to a liquid storage tank.

[0029] The beneficial effect of this solution is that the liquid storage tank is used to store water, making cleaning more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example The embodiment is basically as follows Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the disinfection device for an obstetric intensive care unit includes a flushing unit, a cleaning unit, a water storage tank, and several disinfection rods. The cleaning unit includes a cleaning cover 2, a linear drive member 14, and a power member 17. The cross-section of the cleaning cover 2 is a prototype, and the vertical cross-section of the cleaning cover 2 is elliptical, so the diameter of the middle portion of the cleaning cover 2 is larger than the diameters of the upper and lower ends. The cleaning cover 2 has an opening at the bottom, and an annular sealing ring 28 is glued to the side wall of the opening. In this embodiment, the sealing ring 28 is made of silicone. Several comb teeth 26 are welded to the inner wall of the cleaning cover 2, with the end initially facing away from the cleaning cover 2 being pointed and curved downward. An annular water inlet cover 21 is provided on the outer periphery of the cleaning cover 2, forming a water inlet chamber 25 between the water inlet cover 21 and the cleaning cover 2. A water outlet hole 27 is provided on the comb teeth 26, and the water outlet hole 27 passes through the cleaning cover 2 and communicates with the water inlet chamber 25. The upper surface of the comb teeth 26 is arc-shaped, and the end of the water outlet hole 27 away from the cleaning cover 2 is located on the side of the arc close to the tip, and there is an angle between the direction of the water outlet hole 27 and the tip of the comb teeth 26 away from the cleaning cover 2. The upper portion of the water inlet cover 21 is connected to a water inlet pipe 22 and a water outlet pipe 24. The water inlet pipe 22 is connected to the water inlet chamber 25, and the end away from the water inlet chamber 25 is connected to the water inlet power element 17. The water outlet pipe 24 is connected to the upper portion of the cleaning cover 2, and the end away from the cleaning cover 2 is connected to the water discharge power element 17. In this embodiment, the water inlet power element 17 is a water pump, and the water discharge power element 17 is a water-steam dual-purpose pump. The water inlet power member 17 in this embodiment is connected to the water tank through a pipeline, and the water tank is provided with a water inlet and is threadedly connected with a water inlet cover to seal the water inlet.

[0033] The disinfection rod includes a head and a rod 41. The head is oval in shape, with a cleaning end 4 at its lower end. The sidewalls of the cleaning end 4 are smooth, curved surfaces covered with a friction plate 46. The friction plate 46 is made of silicone and can be detachably connected to the cleaning end 4 by snapping or magnetic attraction. In its natural state, the diameter of the upper end of the cleaning end 4 is larger than the inner diameter of the sealing ring 28 and smaller than the outer diameter of the sealing ring 28, allowing the head to slide vertically over the sealing ring 28 by deforming the sealing ring 28.

[0034] A cleaning layer is provided above the cleaning end 4. In this embodiment, the diameter of the portion of the head facing the bottom of the cleaning layer is smaller than the diameter of the top of the cleaning end 4, forming a step 45 at the top of the cleaning end 4. The cleaning layer is composed of several flexible filaments 44 made of existing microfiber material. Specifically, the flexible filaments 44 are distributed along the circumference of the head, with one end fixed to the head and the other end adjacent to the cleaning cover 2. In actual implementation, the length of the flexible filaments 44 is controlled to ensure initial contact between the cleaning layer and the comb teeth 26 when they are opposite each other. The ends of the flexible filaments 44 facing away from the head are all tilted upward, and the lowest flexible filament 44 is higher than the lowest comb teeth 26.

[0035] A cavity 42 is provided inside the head, and a liquid inlet channel 43 is provided at the top of the head. The diameter of the rod 41 is smaller than the diameter of the upper end of the head. The lower end of the rod 41 is threadedly engaged with the liquid inlet channel 43, sealing the cavity 42. An extension tube 23 is welded to the bottom of the cleaning cover 2. The cross-section of the extension tube 23 is circular, and the diameter of the lower end of the extension tube 23 is larger than the diameter of the head.

[0036] Above the cleaning cover 2, sleeve 11 and main unit 1 are positioned in sequence. The upper end of sleeve 11 is bolted to the bottom of main unit 1, while the lower end is fixed to the head or alternatively, engaged by threads. The upper end of rod 41 passes through sleeve 11 and extends into main unit 1. A gap is formed between rod 41 and sleeve 11, ensuring that rod 41 can rotate relative to sleeve 11 or slide vertically.

[0037] A guide cylinder 12 is vertically welded to the inside of the main unit 1. A through hole is provided on the top of the main unit 1 and a positioning cylinder 3 is mounted thereon via a bearing. The through hole is opposite to the positioning cylinder 3 and has a diameter slightly larger than the diameter of the rod 41, ensuring that the upper end of the rod 41 can extend from the through hole to above the positioning cylinder 3. In this embodiment, the guide cylinder 12, positioning cylinder 3, through hole, and rod 41 are coaxial, and the cross-sections of the upper end of the rod 41 and the positioning cylinder 3 are all quadrilaterals. After the rod 41 slides upward, the rod 41 can slide into the positioning cylinder 3 and rotate with the positioning cylinder 3. The outer wall of the positioning cylinder 3 is keyed to a driven gear. The power member 17 and the linear drive member 14 are both mounted in the main unit 1. In this embodiment, the power member 17 and the linear drive member 14 are both micromotors. The output shaft of the power member 17 is connected to a driving gear meshing with the driven gear via a coupling. Specifically, the driving gear and the driven gear in this embodiment are both bevel gears.

[0038] The guide cylinder 12 is located below the positioning cylinder 3. An annular slider 5 is slidably connected to the guide cylinder 12. The slider 5 is provided with an L-shaped mounting groove, and a turntable 52 is provided in the mounting groove. The turntable 52 has a T-shaped vertical projection. An annular cover plate 51 is provided above the mounting groove and is fixed to the slider 5 by bolts. The cover plate 51 is used to limit the turntable 52 and ensure that the turntable 52 can rotate relative to the slider 5 but will not completely separate from the slider 5. An annular elastic ring 53 is glued to the inner wall of the turntable 52. In this embodiment, the elastic ring 53 is made of elastic rubber. In its natural state, the inner diameter of the elastic ring 53 is slightly smaller than the diameter of the rod 41. When the rod 41 slides upward, the elastic ring 53 can be deformed and pass through the elastic ring 53, thereby ensuring that the slider 5 can drive the rod 41 to slide synchronously when it slides vertically. A connecting rod 16 is welded to the left wall of the slider 5. A through slot 13 is vertically defined on the left wall of the guide cylinder 12. The left end of the connecting rod 16 passes through the through slot 13 and extends to the left side of the guide cylinder 12. A ball screw 15 is provided below the linear drive 14. The screw 15 of the ball screw 15 is vertically arranged and its upper end is connected to the output shaft of the linear drive 14 via a coupling. The nut seat of the ball screw 15 is connected to the connecting rod 16 via screws, allowing the nut seat to drive the connecting rod 16 to slide upward or downward synchronously.

[0039] The specific implementation process is as follows: When the disinfection device of this embodiment is used, the rod 41 is inserted upwardly through the opening of the cleaning cover 2 and the sleeve 11 into the guide cylinder 12 until the upper end of the rod 41 passes through the elastic ring 53 and extends into the positioning cylinder 3, at which point the head is located in the cleaning cover 2. Then, cold boiled water or iodine tincture is introduced into the cavity 42 through the water inlet pipe 22. For example, cold boiled water flows out through the water outlet holes 27 on the comb teeth 26 to moisten the flexible wire 44.

[0040] Then close the water inlet power member 17, start the linear drive member 14, and drive the slider 5 downward through the linear drive member 14 to make the head slide out from under the woven extension sleeve 11. At this time, turn on the power member 17 and the drainage power member 17, and combine with the existing flusher to try to make the lower flexible wire 44 contact with the perineum to scrub the scab area. The power member 17 drives the positioning cylinder 3 to rotate, driving the rod 41 and the head to rotate. Specifically, at this time, the speed of the power member 17 is controlled so that when the head rotates, the droplets on the flexible wire 44 will not detach from the flexible wire 44 due to centrifugal action; and when the drainage power member 17 is working, a negative pressure is formed in the cleaning cover 2 and the extension cylinder 23.

[0041] During scrubbing, the disinfection device is tilted so that the rod 41 and the head are at a small angle to the skin. The lower end of the extension tube 23 is positioned close to the area to be cleaned. A small amount of cold boiled water is dripped onto the area to be cleaned through the irrigator, diluting the blood and blood scabs in the scrubbed area. The diluted blood adheres to the flexible wire 44 and is drawn into the cleaning cover 2 and the extension tube 23 due to the negative pressure generated within the cleaning cover 2 and the extension tube 23. In actual implementation, two water outlet pipes 24 can be provided, with the other one connected to the extension tube 23, to further promote the rapid discharge of blood drawn into the extension tube 23.

[0042] After cleaning is completed or when there are more blood scabs on the flexible thread 44, the head is slid upward again into the cleaning cover 2 through the linear drive member 14, and the water inlet power member 17 is started to use cold boiled water to clean the flexible thread 44. When the head rotates, the comb teeth 26 comb the flexible thread 44, causing the blood scabs on the flexible thread 44 to fall off. The cleaned flexible thread 44 and the head can slide down again to continue scrubbing the perineum.

[0043] When a mother has a tear or other wound during childbirth, the cleaning end 4 is used to scrub the skin around the wound. Compared with the flexible wire 44, the cleaning end 4 is smoother and less likely to cause secondary damage to the wound. In actual implementation, if the wound has begun to heal and there is a blood scab around the wound that is difficult to fall off, the friction plate 46 is installed on the cleaning end 4. Compared with the smooth cleaning end 4, the friction between the friction plate 46 and the skin is relatively greater, and the cleaning effect is better.

[0044] When the perineum of a parturient is swollen due to a tear, episiotomy, or other wound, ice cubes or ice water are added to the cavity 42 to keep the head and cleaning end 4 at a low temperature. At this time, the friction plate 46 is removed and the smooth cleaning end 4 is placed against the swollen area to apply an ice compress to the swollen area, relieving the pain of the parturient and promoting the reduction of swelling. After a certain number of uses, the disinfecting stick in this solution can be removed and replaced to prevent wound infection.

[0045] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
