Description

 The present invention relates to a sputum suction device, and more particularly to a sputum suction device having a rotation switch.

 Some patients lying on the bed cannot discharge sputum on their own. Such patients require medical staff to drain the sputum using a sputum suction device. A conventional sputum suction device includes a patient-side joint connected to a patient's nostril, an oxygen supply joint connected to an oxygen supply source, a sputum suction joint, and a cleaning joint. In use, oxygen necessary for breathing of the patient is continuously supplied by supplying oxygen from the oxygen supply source from the oxygen supply joint into the patient's nostril via the patient side joint. When the patient's vagina is aspirated, the medical staff penetrates the vagina suction tube into the vagina suction joint and inserts it into the patient side joint. Next, the sputum in the patient's nostril is sucked into the sputum suction tube by negative pressure. After the soot suction is completed, the medical staff inserts the cleaning tube into the cleaning joint, flows the cleaning liquid from the cleaning tube into the cleaning joint, and cleans the soot remaining in the suction device.

 However, some conventional sputum suction devices are not provided with a switch. When the switch is not provided, in the process of sucking sputum, part of oxygen is sucked by the negative pressure of the sputum suction tube, so that oxygen supplied to the patient is reduced and oxygen is wasted. Also, in the cleaning process, part of oxygen flows out by the cleaning liquid, so that the amount of oxygen supplied to the patient decreases and part of oxygen is wasted.

 Another problem with the conventional phlegm suction device is that, after the phlegm suction is completed, when the medical staff pulls out the phlegm suction tube from the moth suction device, wrinkles remain on the outer surface of the moth suction tube. It is done. Since sputum contains pathogenic bacteria, there is a risk of infection to medical staff or cleaning workers.

The inventor of the present invention aimed to solve the problems in the above-described conventional sputum suction device.
In addition, as a conventional sputum suction device, there exist some which are disclosed by patent document 1, 2, for example.

 It is an object of the present invention to prevent oxygen from being sucked and flowing out in the process of sucking soot and to prevent soot from remaining on the outer surface of the soot suction pipe. An object of the present invention is to provide a sputum suction device having a switch.

 In order to solve the above-described problems, the scissor suction device having the rotation switch of the present invention includes a main body and a rotation switch.

 A patient side joint and an oxygen supply joint communicating with the patient side joint are provided at one end of the main body. The other end of the main body is provided with a soot suction joint and a cleaning joint communicating with the soot suction joint. The main body further has a connecting portion communicating with the cleaning joint.

 The rotation switch is attached to the connection portion and can switch between the first position and the second position. The rotary switch is provided with a cleaning liquid inlet communicating with the cleaning joint, a cleaning liquid outlet communicating with the cleaning liquid inlet and the soot suction joint, and two soot suction holes arranged opposite to both sides of the cleaning liquid inlet. Further, a heel scraping plate is provided on the periphery of the heel suction hole near the heel suction joint.

 When the rotation switch is in the first position, the two heel suction holes face the patient side joint and the heel suction joint, so that the patient side joint and the heel suction joint communicate with each other. When the rotation switch is in the second position, communication between the patient side joint and the heel suction joint is blocked.

 When the rotation switch is in the first position, the heel scraping plate is disposed on the periphery of the heel suction hole close to the heel suction joint.

 The sputum suction device of the present invention has a rotation switch. The rotation switch has two mutually opposite saddle suction holes. When the rotation switch is in the first position, since the two heel suction holes face the patient side joint and the heel suction joint, the patient side joint and the heel suction joint communicate with each other. At this time, the heel suction tube can be passed through the heel suction joint and can enter the patient side joint via the two heel suction holes. Thereby, a patient's wrinkle can be sucked. Also, since the two soot suction holes have dimensions that allow the soot suction pipe to pass therethrough, oxygen supplied from the oxygen supply joint is sucked from the two soot suction holes while sucking the soot. Is not sucked into. When the rotation switch is in the second position, since the two heel suction holes do not face the patient side joint and the heel suction joint, communication between the patient side joint and the heel suction joint is blocked. Accordingly, at this time, the cleaning liquid can be injected into the soot suction joint through the cleaning liquid inlet and the cleaning liquid outlet of the rotation switch. Moreover, since oxygen is blocked by the outer wall of the rotation switch, it does not enter the heel suction joint. That is, according to the present invention, the rotation switch can prevent oxygen from being sucked and flowing out during the soot suction process.

 In addition, when the rotation switch is in the first position, the heel suction plate is provided at the periphery of the heel suction hole near the heel suction joint, so that the heel suction tube is pulled out from the two heel suction holes and the heel suction joint. At this time, the soot remaining on the outer surface of the soot suction pipe is scraped off by the soot scraping plate and remains in the rotation switch. Thereby, since no soot remains on the outer surface of the soot suction pipe, it is possible to prevent the pathogenic bacteria in the soot from being infected with medical staff or cleaning workers.

 DESCRIPTION OF EMBODIMENTS Embodiments showing the objects, features, and effects of the present invention will be described in detail with reference to the drawings. The drawings are used for illustration and do not limit the invention.

 Please refer to FIG. 1, FIG. 2 and FIG. As shown in FIGS. 1, 2, and 5, the present invention provides a scissor suction device 1 having a rotation switch 200. The sputum suction device 1 has a main body 100. A patient-side joint 110 is provided at one end of the main body 100 (upper end in FIG. 1). A patient's nose mouth mask M (see FIG. 6) is connected to the patient side joint 110. An oxygen supply joint 120 communicating with the patient-side joint 110 is provided near the patient-side joint 110 of the main body 1 (left side in FIG. 1). An oxygen pipe 300 is inserted and connected to the oxygen supply joint 120. A heel suction joint 130 is provided at the other end of the main body 100 (lower end in FIG. 1). The soot suction pipe 410 of the soot container 400 is inserted and connected to the soot suction joint 130. A cleaning joint 140 communicating with the heel suction joint 130 is provided near the heel suction joint 130 of the main body 100. A cleaning pipe 500 is inserted and connected to the cleaning joint 140.

 The main body 100 of the sputum suction apparatus 1 further includes a connection portion 150 that communicates with the cleaning joint 140. The connection part 150 is a hollow tubular shape. The soot suction joint 130, the cleaning joint 140, and the connecting portion 150 communicate with each other. The rotation switch 200 is inserted and connected to the connection unit 150. A notch 151 is formed at the periphery of the connecting portion 150. The notch 151 occupies about a quarter (about 90 degrees) of the circumference. The notch 151 limits the rotation range of the rotation switch 200. A convex edge 152 is formed on the outer surface of the connecting portion 150. A groove 153 is provided between the convex edge 152 and the notch 151. A sealing ring 154 (such as an O-ring) is disposed in the groove 153. A state in which the rotation switch 200 is combined with the connection unit 150 is shown in FIG.

 The rotation switch 200 is attached to the connection unit 150. The rotation switch 200 can switch between the first position P1 and the second position P2. More specifically, the rotation switch 200 includes a rotation lid portion 210 and an insertion connection portion 220 that protrudes from the rotation lid portion 210 and is inserted into the connection portion 150. A display member 211 is formed on the outer surface of the rotating lid 210. The display member 211 displays the position of the rotation switch 200 to the user.

 As can be seen from the cross-sectional view of FIG. 6, the insertion connecting portion 220 is tubular, and a partition plate 221 is formed therein. The partition plate 221 divides the inside of the insertion connecting portion 220 into two regions. A cleaning liquid inlet 222 communicating with the cleaning joint 140 is formed in a region near the cleaning joint 140 of the divided insertion connection portion 220. Further, on the outer wall of the insertion connecting part 220, there are a cleaning liquid outlet 223 communicating with the cleaning liquid inlet 222 and the soot suction joint 130, and two soot suction holes 224, 225 arranged on both sides of the cleaning liquid inlet 222 and facing each other. Provided. More specifically, as can be seen from FIG. 1, one scissor suction hole 224 is provided on the same straight line as the display member 211. Therefore, when the rotation switch 200 is in the first position P1 (the display member 211 is in the upper position) as shown in FIG. 3, the two sputum suction holes 224 and 225 are arranged up and down, and the patient side Since the joint 110 and the heel suction joint 130 are opposed to each other, the patient side joint 110 and the heel suction joint 130 communicate with each other (see FIG. 4). In addition, since the inner diameter of the soot suction holes 224 and 225 is substantially the same as the outer diameter of the soot suction pipe 410, the soot suction pipe 410 can penetrate the two soot suction holes 224 and 225 and be tightly connected. Combined.

 Here, as can be seen from FIG. 1, a heel scraping plate 226 is provided on the periphery of the heel suction hole 225 near the heel suction joint 130 in the two heel suction holes 224 and 225. The scissor scraping plate 226 has a through hole 2261. The inner diameter of the through hole 2261 is slightly smaller than the outer diameter of the soot suction pipe 410. However, since the material of the heel scraping plate 226 has flexibility, the heel suction tube 410 and the heel scraping plate 226 can be penetrated by slightly elastically deforming the through-hole 2261. Can be combined closely. When pulling out the soot suction tube 410 from the soot suction holes 224 and 225, the soot scraping plate 226 can scrape the soot remaining on the outer surface of the soot suction tube 410.

 In order to improve convenience when replacing the heel scraping plate 226, the heel scraping plate 226 is not bonded and fixed on the heel suction hole 225 in the embodiment shown in FIG. Engaging protrusions 2251 are formed around both sides of the heel suction hole 225 close to the heel suction joint 130. In addition, two engagement grooves 2262 that are fitted and fixed to the two engagement convex portions 2251 are provided on the surface of the scraper scraping plate 226. By fitting and fixing the two engaging grooves 2262 of the scissor scraping plate 226 and the engaging projections 2251 on both sides of the scissor suction hole 225, the scissor scraping plate 226 can be attached to and detached from the scissor suction hole 225. It is attached to.

 As can be seen from FIG. 4, a vent hole 227 facing the cleaning liquid outlet 223 is selectively provided on the wall of the insertion connecting portion 220. The vent hole 227 has a small hole diameter and allows only air to pass therethrough, and the vent hole 227 can enhance the convenience of the cleaning operation. Of course, since the air holes 227 are selectively provided, the cleaning operation can be performed without the air holes 227 being provided. However, if the vent hole 227 is not provided, the cleaning liquid cannot be smoothly fed into the rotation switch 200 unless the water pressure of the cleaning liquid is high.

 Please refer to FIG. 5 and FIG. As shown in FIGS. 5 and 6, when the rotation switch 200 is in the first position P <b> 1, the bag suction tube 410 in the bag container 400 is inserted into the bag suction joint 130, and the two switches of the rotation switch 200 are inserted. The suction holes 224 and 225 can be penetrated to enter the patient side joint 110. As shown by the dotted arrow in FIG. 6, oxygen from the oxygen pipe 300 flows into the oxygen supply joint 120 and smoothly flows into the patient side joint 110 and is not affected by the sputum suction pipe 410. Moreover, since the inner diameter of the soot suction holes 224 and 225 is substantially the same as the outer diameter of the soot suction pipe 410, the soot suction pipe 410 is closely combined when passing through the soot suction holes 224 and 225. As a result, oxygen does not pass through the soot suction holes 224 and 225 and flow into the soot suction joint 130. Accordingly, in the process of sucking the soot, the rotation switch 200 can prevent oxygen from being sucked into the soot suction joint 130 and the soot container 400, so that oxygen can be prevented from being wasted. And the patient does not feel a decrease in oxygen supply.

 Please refer to FIG. As shown in FIGS. 7 to 9, when the rotation switch 200 is in the second position P2, the rotation switch 200 is rotated 90 degrees, so that the two scissor suction holes 224 and 225 are rotated. After that, the patient side joint 110 and the heel suction joint 130 are not aligned. Thereby, the communication between the patient side joint 110 and the heel suction joint 130 is blocked. At this time, the washing liquid outlet 223 and the sputum suction joint 130 communicate with each other, and the vent hole 227 faces the patient side joint 110. As shown by the thick dotted arrow in the upper half of FIG. 9, oxygen from the oxygen tube 300 flows into the oxygen supply joint 120 and then flows into the patient side joint 110 very smoothly. Further, since the hole diameter of the vent hole 227 is small and the gas flows into a path having a small resistance force, most of the oxygen cannot pass through the vent hole 227. The cleaning liquid in the cleaning pipe 500 flows from the cleaning joint 140 into the cleaning liquid inlet 222 of the insertion connection part 220 of the rotation switch 200, flows into the soot suction pipe 410 from the cleaning liquid outlet 223, and reaches the soot container 400. .

 Compared with the prior art, the present invention has the following effects.

 The sputum suction device 1 of the present invention has a rotation switch 200. The rotation switch 200 includes two mutually opposite saddle suction holes 224 and 225. When the rotation switch 200 is at the first position P1, the two heel suction holes 224 and 225 are opposed to the patient side joint 110 and the heel suction joint 130, so that the patient side joint 110 and the heel suction joint 130 communicate with each other. At this time, the heel suction tube 410 can penetrate the heel suction joint 130 and enter the patient side joint 110 via the two heel suction holes 224 and 225. Thereby, a patient's wrinkle can be sucked. In addition, since the size of the two soot suction holes 224 and 225 has only a size that allows the soot suction pipe 410 to pass through, the oxygen supplied from the oxygen supply joint 120 is sucked into the two soot suctions while sucking up the soot. It is not sucked from the holes 224 and 225 to the heel suction joint 130. When the rotation switch 200 is in the second position P2, the two heel suction holes 224 and 225 do not face the patient side joint 110 and the heel suction joint 130, and therefore, between the patient side joint 110 and the heel suction joint 130. Communication is interrupted. Accordingly, at this time, the cleaning liquid flowing into the cleaning joint 120 from the outside can be injected into the soot suction joint 130 via the cleaning liquid inlet 222 and the cleaning liquid outlet 223 of the rotation switch 200. Further, since oxygen is blocked by the outer wall of the rotation switch 200, it does not enter the heel suction joint 130. That is, according to the present invention, the rotation switch 200 can prevent oxygen from being sucked out and discharged during the soot suction process.

 Further, when the rotation switch 200 is in the first position P1, the heel scraping plate 226 is provided at the periphery of the heel suction hole 225 near the heel suction joint 130. When pulling out from 224, 225 and the heel suction joint 130, the heel remaining on the outer surface of the heel suction tube 410 is scraped off by the heel scraping plate 226 and remains in the rotation switch 200. Thereby, since no soot remains on the outer surface of the soot suction pipe 410, it is possible to prevent the pathogens in the soot from infecting medical staff or cleaning workers.

 As can be seen from the above, the present invention has industrial applicability, novelty and inventive step, and the structure of the present invention is unpublished, and thus completely meets the requirements of the patent application.
