Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a throat care sputum suction device. Background Art

[0002] The suction device mainly includes electric multifunctional negative pressure suction devices and simple manual suction devices. The operating end needs to be connected to a suction tube or a sponge suction tube before use. Generally, an electric type is commonly used, with a power switch and a manual switch, and negative pressure is used for suction and oral care. The existing suction device is an indispensable device in nursing. When the suction device is used, the suction tube needs to be manually connected to the negative pressure suction device, and the negative pressure generated by the negative pressure suction device is used for suction. Once the negative pressure is unstable, it will cause sputum reflux. Therefore, the suction device needs an anti-reflux mechanism to prevent sputum reflux. In addition, since the wall of the suction tube is sealed, it is also troublesome to clean. Therefore, after its use, the attachments on the internal wall are often difficult to remove, and the cleanliness of the inside of the suction tube is difficult to capture with the naked eye of medical staff. Suction tubes with insufficient cleanliness are put into use again, which is low in safety.

[0003] CN118743793A discloses a suction device for deep sputum suction. In order to solve the problem that sputum enters the throat of the patient for the second time, resulting in the affected suction effect, the contact piece and the notch are set, and the contact piece is used to extend into the mouth of the patient. Then, the suction tube extended into the mouth of the patient passes through the contact piece and the notch and extends into the throat of the patient. Through the above-mentioned action, when the suction tube is subsequently withdrawn, it will not contact the mouth of the patient, and thus the sputum on the outer wall of the suction tube is not easily scraped and retained in the mouth of the patient. At the same time, the swallowing action of the patient will not suck the sputum on the outer wall of the suction tube for the second time, thereby reducing the probability of affecting the suction effect. Although it can reduce the falling of sputum on the outer wall of the suction tube, it still cannot ensure the complete cleaning of the internal tube wall, and cannot avoid the phenomenon of sputum reflux when the negative pressure is unstable. CN111467584A discloses a sputum suction device, including a sputum suction tube, a dispersion component, a connector and a negative pressure device. The sputum suction tube is connected to the negative pressure device, and the sputum suction tube is connected to the connector through the dispersion component. The dispersion component includes a base body and a sliding sleeve. The base body is hollow and forms a dispersion cavity. One end of the base body is recessed into the dispersion cavity to form a columnar protrusion. The side opposite to the columnar protrusion forms a receiving groove. An iron core and a circuit board are arranged in the receiving groove. A winding is arranged on the iron core. The circuit board is electrically connected to the winding. A connecting port is arranged at the other end of the base body. The sliding sleeve is slidably sleeved on the columnar protrusion. The inner wall of the sliding sleeve is embedded with There is a magnetic ring, which is made of a permanent magnet. Dispersion grooves are arranged at intervals on the outer peripheral wall of the sliding sleeve. A suction port is also arranged on the base. The suction tube is connected to the base through the suction port. The change of the magnetic pole of the iron core is realized by changing the direction of the current. A magnetic ring is further arranged on the inner wall of the sliding sleeve, thereby driving the sliding sleeve in the dispersion chamber to slide back and forth, dispersing the incoming sputum, avoiding the concentration of sputum and blockage, and thus avoiding the phenomenon of sputum reflux. However, this method is easily limited by materials, is inconvenient to clean, and there will still be sputum residue, which will cause changes in the working environment and thus affect the working environment and shorten the life of the suction tube.

[0004] In order to solve the deficiencies of the existing technology, there is an urgent need for a sputum suction device that is anti-reflux and easy to clean. Summary of the invention

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0020] Embodiment 1: Figure 1 As shown, a sputum suction device for throat care comprises a sputum suction tube 1, the left end of which is connected to a negative pressure suction device, a baffle body 2 is arranged in the right end port of the sputum suction tube 1, the baffle body 2 is a conical structure with a hollow interior and an open end, a limiting protrusion extending outward is arranged at the open end of the baffle body 2, and a gapless knife slit is opened in the middle of the other end of the baffle body 2 in a M-shaped shape, the right end port of the sputum suction tube 1 is covered with a fixed sleeve 3, the fixed sleeve 3 is threadedly fixedly sleeved on the right end port of the sputum suction tube 1, and the fixed sleeve 3 and the right end of the sputum suction tube 1 clamp and fix the limiting protrusion extending outward of the baffle body 2.

[0021] In this embodiment, the material of the bluff body is silicone material.

[0022] In this embodiment, when suctioning sputum, the negative pressure suction device is turned on to generate negative pressure in the suction tube 1. Under the action of the internal and external pressure difference, the baffle body 2 is deformed and the gapless slit portion is opened, so that the sputum in the patient's throat is sucked into the suction tube 1. After the negative pressure suction device tube wall, the pressure difference between the inside and outside of the suction tube 1 decreases. As the pressure difference between the inside and outside of the suction tube 1 decreases, the baffle body 2 is deformed, and the tube wall at the gapless slit portion prevents the sputum from flowing back out of the suction tube.

[0023] Embodiment 2: Figure 2As shown, on the basis of embodiment 1, a positioning rod 4 is arranged in the fixed sleeve 3, the axis of the positioning rod 4 coincides with the axis of the fixed sleeve 3, and two support rods 5 are symmetrically arranged between the fixed sleeve 3 and the end of the positioning rod 4, one end of the support rod 5 is fixedly connected to the end of the positioning rod 4, and the other end of the support rod 5 is fixedly connected to the inner wall of the fixed sleeve 3, and the other end of the positioning rod 4 away from the support rod 5 is a spherical structure, and is in contact with the gap-free knife gap portion of the baffle body 2.

[0024] In this embodiment, one end of the spherical structure of the positioning rod 4 is used to support the bluff body 2. When sputum refluxes, the positioning rod 4 is used to support the gapless knife gap portion of the bluff body 2 to prevent the bluff body 2 from deforming and leaking out from the knife gaps.

[0025] Embodiment 3: Figure 3-4 As shown, on the basis of embodiments one and two, the suction tube 1 is symmetrically fixed with a reflux pipe 6 and a cleaning tube 7, and an adjusting plug 8 is slidably connected inside the suction tube 1. The adjusting plug 8 consists of a large cylinder at the left end and a small cylinder at the right end. A channel running through the left and right ends is arranged in the middle of the adjusting plug 8, and a side through hole is arranged on the side wall of the small cylinder of the adjusting plug 8. A spring 9 is arranged in the suction tube 1, and one end of the spring 9 is fixedly connected to the inner wall of the suction tube 1, and the other end of the spring 9 is fixedly connected to the left end of the adjusting plug 8.

[0026] In this embodiment, the length of the reflux pipe 6 is greater than the sum of the lengths of the adjusting plug 8 and the spring 9, one end of the reflux pipe 6 is connected to the sputum suction tube 1 near the right end, the other end of the reflux pipe 6 is connected to the sputum suction tube 1, the cleaning tube 7 is connected to the sputum suction tube 1, and when the right end of the adjusting plug 8 is in contact with the gap-free knife gap of the baffle body 2, the connecting part of the cleaning tube 7 and the sputum suction tube 1 is located on the left side of the adjusting plug 8.

[0027] In this embodiment, when suctioning sputum, the negative pressure suction device works to generate negative pressure in the sputum suction tube 1. Under the action of the internal and external pressure difference, the adjusting plug 8 slides in the sputum suction tube 1 and compresses the spring 9 to separate the adjusting plug 8 from the blocking body 2. As the adjusting plug 8 slides, the large cylindrical side wall of the adjusting plug 8 blocks the connecting part between the cleaning tube 7 and the sputum suction tube 1. At the same time, the blocking body 2 is deformed and the gapless knife gap is opened, thereby sucking the sputum in the patient's throat into the sputum suction tube 1.

[0028] After the sputum suction work is completed, the negative pressure suction device is closed, and the plug 8 is adjusted to slide to the right under the elastic force of the spring 9. The plug 8 and the end of the positioning rod 4 are adjusted to fix the gapless knife gap of the bluff body 2 by squeezing to prevent the slit of the bluff body 2 from opening. At the same time, the bluff body 2 blocks the right end port of the middle channel of the adjusting plug 8, and the cleaning water is flushed from the cleaning pipe 7 to the sputum suction pipe 1. On the one hand, the cleaning water flows directly from the sputum suction pipe 1 to the negative pressure suction device to clean the inner wall of the sputum suction pipe 1. On the other hand, the cleaning water flows to the bluff body 2 through the side through holes provided on the side wall of the small cylindrical part of the adjusting plug 8 and the middle channel of the adjusting plug 8, and then flows back to the sputum suction pipe 1 from the reflux pipe 6 to clean the right end port of the sputum suction pipe 1 and the bluff body 2. That is, under the cooperation of the adjusting plug 8 and the reflux pipe 7, not only the sputum is prevented from flowing back to the cleaning pipe 7, but also the channel formed by the reflux pipe 7 is used to make the cleaning water flow to the bluff body 2 and then flow back to the sputum suction pipe 1, so as to avoid the occurrence of cleaning dead corners and ensure the cleaning effect.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
