Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.

Referring to fig. 1, the present embodiment provides a backflow-preventing nasopharyngeal dual-purpose sputum aspirator, which includes: the pharyngeal conduit 1 comprises a first hose 1.2 and a first sputum suction nozzle 1.1 arranged at one end of the first hose 1.2; a nasal tube 2, which comprises a second hose 2.2 and a second sputum suction nozzle 2.1 arranged at one end of the second hose 2.2. The sputum suction nozzle can be sleeved at one end of the hose, and can also be produced integrally with the hose during production. The flow channel control part 3 is provided with a first connecting port 3.1, a second connecting port 3.2 and a third connecting port 3.3, the other end of the first hose 1.2 is connected with the first connecting port 3.1, and the other end of the second hose 2.2 is connected with the second connecting port 3.2; and the

connector

4, 4 one ends of connectors with the third connector 3.3 links to each other, and the other end is used for connecting medical sputum aspirator pipe. The nasal tube 2, the pharyngeal tube 1 and the connector 4 are connected together through the flow passage control part 3 to form an integrated sputum aspirator for aspirating sputum of the mouth and nose of a patient. The present embodiment is a disposable article that can be recycled by directly releasing the connection with the medical sputum aspirator after use.

The flow control element 3 includes a housing 3.4 and a control valve 5 disposed in the housing 3.4, and the first connection port 3.1, the second connection port 3.2, and the third connection port 3.3 are disposed on the housing 3.4, where the connection ports may be directly formed on the housing, or may be formed on the surface of the housing to connect with other hoses through a protruding pipe. The control valve 5 is used for shunting, planning the flow channel of the liquid and avoiding confusion, and preventing the patient from backflowing and back-sucking due to long-time unsmooth breathing or oral foreign body sensation in the sputum sucking process. Specifically, the first connection port 3.1 and the third connection port 3.3 or the second connection port 3.2 and the third connection port 3.3 are selectively communicated with each other.

In order to achieve the above effect, the control valve 5 may be any device capable of controlling the flow direction of the liquid, such as a one-way valve, a channel switch, and the like. The device comprises a rotating part 5.3, a first baffle 5.1 and a second baffle 5.2; the first stop 5.1 and the second stop 5.2 are arranged in the rotating part 5.3 in this order in the direction of the axis of rotation of the rotating part 5.3, wherein the arrangement is an integrated connection during production and is fixedly arranged on the rotating part 5.3. This fixation means: when the rotating part 5.3 is rotatory, can drive first separation blade 5.1 with second separation blade 5.2 carries out the syntropy and rotates, also means simultaneously when first separation blade 5.1 or second separation blade 5.2 atress are rotatory, also can drive rotating part 5.3 and another separation blade and carry out the syntropy and rotate.

Specifically, the first blocking piece 5.1 is used for blocking the first connecting port 3.1, that is, the cross-sectional area of the first blocking piece 5.1 in the normal direction of the face of the housing 3.4 provided with the connecting port is larger than the cross-sectional area of the opening of the first connecting port 3.1, so that the opening can be completely blocked. When the first blocking piece 5.1 blocks the first connector 3.1, the second blocking piece 5.2 spaced from the first blocking piece 5.1 should be driven by the rotating part 5.3 to approach the first connector 3.1 and be far away from the second connector 3.2, so that the opening of the second connector 3.2 is completely exposed, and a space for communicating the second connector 3.2 with the third connector 3.3 is arranged in the casing 3.4, and sputum flows through the space and cannot enter another path through the first connector 3.1; similarly, the second blocking piece 5.2 is used for blocking the second connecting port 3.2, and when the second blocking piece 5.2 blocks the second connecting port 3.2, the first blocking piece 5.1 is far away from the first connecting port 3.1, so that the shell 3.4 is internally provided with a space for communicating the first connecting port 3.1 with the third connecting port 3.3.

For better application in practical production and use, the first connection port 3.1 is disposed on a side of the housing 3.4 close to the first blocking plate 5.1, and is located on the same straight line with the center of the opening of the third connection port 3.3. I.e. the default sputum path is from the pharyngeal conduit 1 into the connector 4. Specifically, the surface of the housing 3.4 provided with the first connection port 3.1 is taken as the top, and then the third connection port 3.3 is arranged at the bottom of the housing 3.4, and the planes of the first connection port and the third connection port are parallel to each other. Therefore, when the sputum flows through, the sputum has the shortest path, and the sputum suction can be more quickly assisted for patients.

Sometimes, the patient needs to suck the nasal cavity by using the nasal tube 2 due to the discomfort of the foreign body in the oral cavity or the incomplete suction of the sputum. A second connection opening 3.2 is provided in the side of the housing 3.4, which connection opening is adjacent to the second flap 5.2. When sucking with the pharyngeal conduit 1, the nasal conduit 2 does not have sputum to flow through or suck. When the nasal tube 2 is used, the first baffle 5.1 covers the first connecting port 3.1, and sputum flows to the third connecting port 3.3 through the second connecting port 3.2 to complete sputum suction.

The principle of suction is that the sputum is sucked by negative pressure in the tube caused by air suction of the medical sputum aspirator, so good air tightness is necessary. In practical application, parts such as an air valve, an air tap plug and the like which can realize ventilation and sealed environment switching can be used. The pressure switch group of the embodiment adopts a blocking type pressure switch, the pressure switch comprises a pressure pipe 6.1 and a pressure bolt 6.2, the pressure pipe 6.1 comprises a first end and a second end, the first end is communicated with a corresponding hose, and the other end is exposed in the air; the pressure bolt 6.2 is shaped and sized to fit into the opening of the second end of the pressure tube 6.1 for insertion into the second end of the pressure tube 6.1 to form a closed space for the pressure tube 6.1.

The nasal tube 2 and the pharyngeal tube 1 are complementary auxiliary devices for the physical condition of the patient, and are not necessary devices for simultaneous use. So when one tube is used, the other is inactive. In the present embodiment, the set of pressure switches comprises a first pressure switch 1.6 and a second pressure switch 2.6. The first pressure switch 1.6 is sleeved on the first hose 1.2, and the second pressure switch 2.6 is sleeved on the second hose 2.2. The sputum suction pipe is used for controlling different sputum suction pipes to suck sputum, and only a pressure switch to be used or being used needs to be closed, so that a sealed channel can be formed to suck the sputum.

Furthermore, the sputum suction flow of the oral cavity is different from that of the nasal cavity, so that the practical life sample is reasonably planned and set in specific use and production links, and the specific setting embodiment is not limited. However, in practice, the diameter of the opening of the first suction nozzle 1.1 of the pharyngeal conduit 1 is larger than that of the second suction nozzle 2.1 of the nasal conduit 2, which is better and faster for solving the discomfort of the patient. Meanwhile, because negative pressure exists in the pipeline in the suction process, a limiting sleeve 9 is necessary to be arranged at the opening of the sputum suction nozzle, and the limiting sleeve can be a hard ring or other supporting facilities for fixing and preventing the deformation of the opening of the sputum suction nozzle. The reduction of the working efficiency caused by the reduction of the opening of the sputum suction nozzle in the sputum suction process is avoided.

The dual-purpose sputum aspirator of preventing regurgitation nasopharynx that this embodiment provided sets up the double-end through inhaling the sputum aspirator, can help the patient to solve the discomfort better mutually in addition, reduces medical personnel and frequently changes the problem of inhaling the phlegm mouth in operation process. And the flow direction control valve 3 is arranged, so that the problem that the sputum of the patient is returned to cause infection or discomfort due to the disordered flow direction easily caused by double-communication pipelines is solved.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
