Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a perineal dryer. Background Technology
[0002] In clinical nursing, some patients experience loss of consciousness and diarrhea. The patient's excrement is distributed in the perineum and perianal area. If cleaning is not done properly, or if the perineum and perianal area are not dried in time after cleaning, redness or incontinence dermatitis can easily occur in the patient's perineum and perianal area.
[0003] Existing perineal dryers directly output the gas produced by the drying gas production device to the perineal and perianal areas. When the temperature and humidity of the gas output by the drying gas production device are unstable, the gas directly acts on the patient's perineal or perianal areas, which can cause physical discomfort and may even lead to disease in severe cases.
[0004] Therefore, how to provide a perineal dryer that can output dry gas with stable temperature and humidity to the patient's perineal area and perianal region is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] Based on the above analysis, this utility model aims to provide a perineal dryer to solve the technical problem in the prior art where the temperature and humidity of the gas output from the drying gas production device are unstable, and the gas temperature is too high or too low, which can easily cause discomfort to the patient.
[0006] The objective of this utility model is mainly achieved through the following technical solutions:
[0007] A perineal dryer includes a mixing chamber, an output chamber, and a perianal output tube; the mixing chamber and the output chamber are separated by a first end face, and a first through hole is provided on the first end face, through which the mixing chamber and the output chamber are connected; the perianal output tube is connected to the output chamber;
[0008] The mixing chamber includes a first curved surface and an input end formed on the first curved surface; the first curved surface and the first end face form the mixing chamber, and a first air guide groove is formed on the inner wall of the first curved surface, which is spirally arranged along the first curved surface; the input end is connected to the output end of the dry gas production device through a pipeline; the input end is arranged along the first air guide groove.
[0009] The dry gas output from the dry gas production device enters the mixing chamber through the input end, moves along the first air guide groove for gas mixing, and is delivered to the output chamber and the perianal output pipe through the first through hole. The dry gas is then output to the patient's perineal and perianal areas through the output chamber and the perianal output pipe.
[0010] Furthermore, it also includes a delivery pipe, one end of which is connected to the first through hole, and the other end of which is disposed in the output chamber.
[0011] Furthermore, a second air guide groove is provided on the inner wall of the conveying pipe, and the drying gas moves along the second air guide groove inside the conveying pipe.
[0012] Furthermore, a second through hole is provided on the side wall of the conveying pipe, and multiple second through holes are arranged along the second air guide groove; during the movement of the dry gas in the second air guide groove, it is discharged from the second through hole to the output chamber.
[0013] Furthermore, the output chamber includes a second end face and a second curved surface; the second end face faces the patient's perineal region; the second curved surface faces the patient's thigh region.
[0014] Furthermore, a third through hole is provided on the second end face, and multiple third through holes are arranged in a matrix on the second end face; the drying gas is output to the patient's perineal area through the third through hole.
[0015] Furthermore, the diameters of the multiple third through holes are different; from the corresponding position of the perineum to the peripheral area of the second end face, the diameter of the third through holes increases from small to large.
[0016] Furthermore, a fourth through hole is provided on the second curved surface, and multiple fourth through holes are arranged in a matrix on the second curved surface; the drying gas is output to the patient's thigh area through the fourth through hole.
[0017] Furthermore, the perianal output tube has a fifth through hole evenly distributed on its wall; the dry gas is output to the patient's perianal area through the fifth through hole.
[0018] Furthermore, it also includes fixed hooks.
[0019] Furthermore, the fixing hook is connected to the output chamber via an elastic rope.
[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:
[0021] (1) In the perineal dryer of this utility model, the drying gas first enters the mixing chamber and extends the movement trajectory of the drying gas in the mixing chamber through the first air guide groove, so that the drying gas is fully mixed in the mixing chamber, ensuring that the drying gas output from the mixing chamber to the output chamber is a drying gas with uniform temperature and humidity. Then, the output chamber delivers the drying gas with stable temperature and humidity to the patient's perineal area and perianal area, quickly drying the patient's perineal area and perianal area. At the same time, it avoids the drying gas with unstable temperature and humidity from damaging the patient's skin.
[0022] (2) The perineal dryer of this utility model has a second air guide groove on the inner wall of the conveying pipe and a second through hole on the side wall of the output pipe. During the movement of the mixed dry gas along the second air guide groove, it is conveyed into the output chamber through the second through hole and then output through the output hole of the output chamber. The setting of the second air guide groove and the second through hole on the conveying pipe allows the mixed dry gas to enter the output chamber from multiple directions and deliver uniform dry gas to the output holes in various directions of the output chamber, avoiding the dry gas from being blown directly onto a certain part of the patient's skin and causing discomfort to the patient.
[0023] (3) The perineal dryer of this utility model includes a second end face facing the perineum, a second curved surface facing the inner thigh, and an anal output tube facing the perianal area. It can dry the perineum, perianal area and other areas of the patient that need to be dried in a complete manner, and there are no requirements for the patient's posture, making it convenient to use.
[0024] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation
[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0032] A specific embodiment of this utility model is as follows: Figure 1 As shown, a perineal dryer is disclosed, which includes a mixing chamber 1, an output chamber 2, and a perianal output tube 3; the mixing chamber 1 and the output chamber 2 are integrally formed; the mixing chamber 1 and the output chamber 2 are separated by a first end face 11, and a first through hole 12 is provided on the first end face 11; the perianal output tube 3 is connected to the output chamber 2;
[0033] like Figure 3 As shown, the mixing chamber 1 includes a first curved surface 13 and an input end 15 formed on the first curved surface 13; the first curved surface 13 and the first end face 11 form the mixing chamber 1, and a first air guide groove 131 is formed on the inner wall of the first curved surface 13, the first air guide groove 131 being spirally formed along the first curved surface 13; the input end 15 is connected to the output end of the dry gas production device through a pipeline; the input end 15 is arranged along the first air guide groove 131;
[0034] The dry gas output from the dry gas production device enters the mixing chamber 1 through the input end 15, moves along the first air guide groove to mix the gas, and is delivered to the output chamber 2 and the perianal output pipe 3 through the first through hole 12. The dry gas is then output to the patient's perineal and perianal areas through the output chamber 2 and the perianal output pipe 3.
[0035] The perineal dryer of this invention delivers drying gas to a mixing chamber 1 via a drying gas production device. A first air guide groove 131 on the inner wall of the first curved surface 13 of the mixing chamber 1 extends the movement trajectory of the drying gas within the mixing chamber 1. During this movement, the drying gas is thoroughly mixed within the mixing chamber 1, ensuring that the drying gas output from the mixing chamber 1 to the output chamber 2 is a drying gas with balanced temperature and humidity. The output chamber 2 then delivers drying gas with stable temperature and humidity to the patient's perineal and perianal areas, achieving rapid drying of the patient's perineal and perianal areas. Simultaneously, it avoids drying gas with unstable temperature and humidity that could damage the patient's skin.
[0036] Two input terminals 15 are provided. The positions of the input terminals 15 on the first curved surface 13 include a first position and a second position. The first position corresponds to the anterior region of the patient's body, and the second position corresponds to the posterior region of the patient's body. In use, the dry gas production device can be connected to the corresponding input terminal 15 according to the patient's posture.
[0037] In this embodiment, the mixing chamber 1 and the output chamber 2 are integrally molded and made of skin-friendly silicone material, which is moderately soft and hard to ensure comfort during use.
[0038] When the mixed dry gas flows from mixing chamber 1 to output chamber 2, to prevent the gas in mixing chamber 1 from being directly output to output chamber 2, resulting in uneven output at the output end of output chamber 2 and causing discomfort to the patient's local skin due to excessive dryness, and to avoid the patient's local skin not being properly dried, in this embodiment, mixing chamber 1 outputs to output chamber 2 through a delivery pipe 14. One end of the delivery pipe 14 is connected to the first through hole 12, and the other end of the output pipe is disposed inside the mixing chamber 1.
[0039] A second air guide groove is provided on the inner wall of the conveying pipe 14.
[0040] like Figure 2 As shown, a second through hole 141 is provided on the side wall of the conveying pipe 14, and the second through hole 141 is tangent to the second air guide groove.
[0041] The dried gas mixed in the mixing chamber 1 enters the delivery pipe 14 and is transported in the second air guide groove on the inner wall of the delivery pipe 14. The second air guide groove is a spirally rising groove structure along the delivery pipe 14. During the spiral movement of the dried gas in the second air guide groove, it moves along the second through hole 141 to the output chamber 2, so that the dried gas entering the output chamber 2 has multiple air directions. The dried gas with different air directions is aimed at different outlets. Different outlets correspond to different skin areas of the patient, which can achieve uniform output of dried gas and dry all areas of the patient.
[0042] In this embodiment, the output chamber 2 includes a second end face 21 and a second curved surface 22; the second end face 21 faces the patient's perineal region; and the second curved surface 22 faces the patient's thigh region.
[0043] In this embodiment, a third through hole 211 is provided on the second end face 21, and a plurality of the third through holes 211 are arranged in a matrix on the second end face 21.
[0044] In this embodiment, the diameters of the multiple third through holes 211 are different; from the perineal position to the periphery of the second end face 21, the diameters of the third through holes 211 increase from small to large.
[0045] The perineal area of the patient is relatively fragile. The diameter of the third through hole 211 corresponding to this area is small, and the spacing between the third through holes 211 is small. The dry gas output from the perineal area is a gentle breeze, which can dry the perineal area while avoiding damage to the perineal area.
[0046] In this embodiment, a fourth through hole 221 is provided on the second curved surface, and a plurality of the fourth through holes 221 are arranged in a matrix on the second curved surface.
[0047] The second curved surface corresponds to the patient's thigh area, and the dry gas entering the output chamber 2 dries the patient's thigh area through the fourth through hole 221.
[0048] In this embodiment, a fifth through hole 31 is provided on the wall of the perianal output pipe 3. Drying gas passes through the output chamber 2 and the perianal output pipe 3 in sequence, and then is output to the patient's perianal area through the fifth through hole 31 on the perianal output pipe 3 to dry the patient's perianal area.
[0049] In this embodiment, a fixing hook 4 is also included, which is connected to the output chamber via an elastic rope 5.
[0050] The perineal dryer can be secured to the patient using the fixing hook 4 for easy use.
[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
