However, in the prior art, the sputum suction tube is manually controlled to rotate and extract, the sputum suction tube shakes greatly in the airway, which may be in contact with the airway for a long time, thereby damaging the mucosa of the airway, throat and the like of the patient. When the sputum suction tube is separated from the human body, the sputum suction tube contacts the sputum on the side wall of the airway when entering the human body, the sputum is easy to adhere to the sputum suction tube, the sputum suction tube is easy to contact the oral cavity or the nasal cavity of the patient, and secondary pollution is easy to occur if the sputum falls into the oral cavity. UTILIZING CONTENT

[0004] The utility model discloses a sputum suction device which solves the technical problem that sputum on the sputum suction tube is easy to cause secondary infection when the sputum suction tube is separated from the human body in the prior art.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A sputum suction device comprises a fixing cylinder connectable with a human body, a through slot matched with a sputum suction tube is arranged on the fixing cylinder, the sputum suction tube is slidably connected with the through slot, a liquid storage cavity is further arranged on the fixing cylinder, the liquid storage cavity is communicated with the through slot, a sputum scraping assembly matched with the sputum suction tube is arranged at the communication position of the liquid storage cavity and the through slot, a protective plate is arranged on one side of the liquid storage cavity, and a through hole matched with the sputum suction tube is arranged on the protective plate.

[0031] The following is combined with Figs. 1-2 This utility model will be described in detail. Example 1

[0032] A suction device, such as Figs. 1-2 As shown, the device includes a fixed cylinder 1 that can be connected to the human body.

The fixed cylinder 1 is also provided with a liquid storage chamber 107 that communicates with the through groove 102. A sputum scraping component that cooperates with the suction tube is provided at the connection between the liquid storage chamber 107 and the through groove 102. A protective plate 105 is provided on one side of the liquid storage chamber 107. The protective plate 105 is provided with a through hole 106 that cooperates with the suction tube.

[0033] In this embodiment, the fixing cylinder 1 and the like are disposable items, and have been sterilized before use.

[0034] In this embodiment, the length of the fixing tube 1 is 1-5cm. When the fixing tube 1 is used for oral suctioning, the length of the fixing tube 1 is 5cm. When the fixing tube 1 is used for nasal suctioning, the length of the fixing tube 1 is 1cm.

[0035] In this embodiment, the protective plate 105, the liquid storage cavity 107 and the through groove 102 are integrally formed with the fixed cylinder 1, and the through hole 106 is integrally formed with the protective plate 105.

[0036] In this embodiment, the size of the through hole 106 is matched with the size of the suction tube, and the suction tube can come into contact with the human body after passing through the through hole 106.

[0037] In this embodiment, the fixing cylinder 1 is made of rigid silicone. Using rigid silicone can reduce the cost of using this device, and rigid silicone has a better adhesion effect on sputum, which increases the difficulty of sputum flowing in the storage chamber 107, thus enabling better storage and preservation of the collected sputum.

[0038] The fixed cylinder 1 is connected with the human body, the through groove 102 is connected with the sputum suction tube, and the position of the sputum suction tube entering the human body can be preliminarily guided, so that the shaking range of the subsequent sputum suction tube in the subsequent sputum suction operation is small, and the contact with the airway and the throat of the patient is reduced to protect the airway and the throat of the patient.

[0039] Further, the sputum scraping assembly is used to scrape the sputum on the sputum suction tube body, so that the sputum is separated from the sputum suction tube, the sputum separated from the sputum suction tube enters the liquid storage cavity 107 and is temporarily stored, and the protective plate 105 is arranged to prevent the sputum stored in the liquid storage cavity 107 from re-entering the human body and causing secondary infection of the human body.

[0040] Meanwhile, the sputum scraping assembly can further guide and limit the position of the sputum suction tube, so that the contact between the sputum scraping assembly and the sputum suction tube is more close, and the scraping effect of the sputum is better. Therefore, the device has excellent guiding and limiting effect, can reduce the harm of the sputum suction tube to the airway and the throat of the patient, and can scrape and collect the sputum adhered to the sputum suction tube body to prevent secondary infection caused by the contact between the sputum and the patient's body.

[0041] In the embodiment, the sputum scraping assembly comprises a first adjusting mechanism arranged on the fixed cylinder 1, the first adjusting mechanism comprises a scraping cylinder 3 slidingly arranged in the through groove 102, one end of the scraping cylinder 3 is provided with a plurality of opening grooves 301 penetrating the side wall of the scraping cylinder 3 and communicating with the top wall of the scraping cylinder 3, and the fixed cylinder 1 is provided with a first inclined surface structure 103 capable of clamping the scraping cylinder 3, and the first inclined surface structure 103 is located at the end of the through groove 102.

[0042] In the embodiment, the opening grooves 301 are integrally formed with the scraping cylinder 3, and the scraping cylinder 3 is made of PVC plastic material.

[0043] In the embodiment, the opening grooves 301 are provided with two, and the two opening grooves 301 are symmetrically arranged.

[0044] In the embodiment, the first inclined surface structure 103 is integrally formed with the fixed cylinder 1, and the first inclined surface structure 103 is arranged at one end close to the liquid storage cavity 107.

[0045] In the embodiment, the inclination angle of the first inclined surface structure 103 is 15°.

[0046] The side wall of the scraping cylinder 3 is provided with two open grooves 301 communicating with the top wall of the scraping cylinder 3. When the scraping cylinder 3 is in sliding connection with the through groove 102, the open grooves 301 can change the diameter of the contact between the scraping cylinder 3 and the first inclined surface structure 103 when the first inclined surface structure 103 contacts the scraping cylinder 3. Through the change of the diameter of the contact between the first inclined surface structure 103 and the scraping cylinder 3, the sputum suction tube in contact with the scraping cylinder 3 can be fixed. This arrangement can make the scraping cylinder 3 cooperate with sputum suction tubes of different diameters, and can fix and clamp the sputum suction tube, thereby increasing the practicability of the device.

[0047] At the same time, this fixing mode can also adjust the clamping force of the scraping cylinder 3 and the sputum suction tube when the first inclined surface structure 103 contacts the scraping cylinder 3, so that the sputum scraping assembly can better scrape the sputum, reduce the total amount of sputum taken out of the fixed cylinder 1 by the sputum suction tube, and at the same time cooperate with the fixed cylinder 1 to reduce the possibility of contacting the human body, thereby improving the protection effect on the human body and effectively protecting the patient.

[0048] In this embodiment, the first inclined surface structure 103 forms a convex structure protruding towards the center of the through groove (102).

[0049] As the scraping cylinder 3 continuously contacts the first inclined surface structure 103, the first inclined surface structure 103 can continuously clamp the scraping cylinder 3 in the direction close to the airway of the human body, so that the gap between the open grooves 301 on the scraping cylinder 3 becomes smaller and smaller, thereby changing the diameter of the scraping cylinder 3 at the position of the first inclined surface structure 103, and further adapting to the size of different sputum suction tubes, better guiding and limiting the sputum suction tube and scraping the sputum. The protection effect on the patient is improved, and the possibility of secondary infection of the patient caused by sputum is prevented.

[0050] In this embodiment, the first inclined surface structure 103 is connected with a guide inclined surface structure 104, and the inclination direction of the guide inclined surface structure 104 is inclined away from the center of the through groove 102.

[0051] In this embodiment, the inclination angle of the guide inclined surface structure 104 is 20°.

[0052] In this embodiment, the guide inclined surface structure 104 is integrally formed with the fixed cylinder 1.

[0053] The sputum scraped by the sputum scraping assembly gradually enters the liquid storage cavity 107 through the guide inclined surface structure 104, and is collected between the liquid storage cavity 107 and the protective plate 105 under the action of gravity. The amount of sputum adhering to the sputum suction tube is small, and during the process of the sputum suction tube being pulled out of the human body, a part of the sputum suction tube is always in contact with the through hole 106. Therefore, the sputum collected in the liquid storage cavity 107 will not flow out of the through hole 106 and contact the patient again, causing secondary infection. The arrangement of the guide inclined surface structure 104 further improves the protection effect on the patient and increases the safety of the device in use.

[0054] In the embodiment, the scraping cylinder 3 is threadedly connected with the through groove 102.

[0055] In the embodiment, the scraping cylinder 3 is provided with an outer thread on the outer side wall, and the through groove 102 is provided with an inner thread matched with the outer thread.

[0056] In the embodiment, the outer thread is arranged on the outer side wall at the position where the scraping cylinder 3 is provided with the open groove 301.

[0057] The scraping cylinder 3 and the through groove 102 are threadedly connected, so that the connection of the two is stable, the sputum suction tube is not loosened, and the stability of the device during use is increased.

[0058] In the embodiment, the through hole 106 is provided with an arc-shaped baffle 2 on the side wall.

[0059] In the embodiment, the arc-shaped baffle 2 is integrally formed with the protection plate 105.

[0060] In the embodiment, the end of the arc-shaped baffle 2 close to the through groove 102 is provided with a bevel structure, and the thickness of the end is 0.3 cm.

[0061] The arc-shaped baffle 2 can cooperate with the through hole 106, so that the sputum collected by scraping moves only in the space between the arc-shaped baffle 2 and the liquid storage cavity 107, further improving the protection effect of the sputum scraped, and further increasing the safety of the device during use.

[0062] In the embodiment, the fixed cylinder 1 is further provided with a tooth groove 101.

[0063] In the embodiment, the tooth groove 101 is integrally formed with the fixed cylinder 1, and the width of the tooth groove 101 is 2 cm.

[0064] The patient can directly bite the tooth groove 101 through the teeth to preliminarily connect the device with the human body, thereby increasing the comfort of the patient when using the device.

[0065] The specific use method of the device is as follows:

[0066] Refer to Figs. 1-2When the device is used, the patient first bites the tooth socket 101 or directly inserts the device into the patient's nostril to preliminarily connect the device with the patient's body. Then the sputum suction tube is taken out and connected with the negative pressure device. After testing the sealing property of the sputum suction tube, the negative pressure opening on the sputum suction tube is punched, and then the sputum suction tube is inserted into the scraping cylinder 3 in the fixed cylinder 1, and the other end of the sputum suction tube is inserted out of the through hole 106 of the protection plate 105 into the human body. When the sputum suction tube reaches the corresponding position in the human body, the medical staff rotates the scraping cylinder 3 to make the first inclined surface structure 103 extrude and fix the scraping cylinder 3 to fix the sputum suction tube, thereby generating an abutment point (or the sputum suction tube is connected with the scraping cylinder 3 and the fixed cylinder 1 first, the length of the other end of the sputum suction tube inserted out of the through hole 106 is matched with the length of the sputum suction tube inserted into the human body, then the sputum suction tube is fixed by rotating the scraping cylinder 3, and then the sputum suction tube is checked and intubated according to the conventional operation, and finally the patient bites the fixed cylinder 1 or inserts the fixed cylinder 1 into the patient's nasal cavity).

[0067] Then the medical staff closes the negative pressure opening and rotates and pulls the sputum suction tube to absorb the sputum in the patient's body. When the sputum suction tube enters the through hole 106 again, it is in contact with the abutment point, and the sputum adhering to the sputum suction tube is scraped and collected by the abutment point of the scraping cylinder 3. The sputum collected by scraping enters the storage cavity 107 through the guide inclined surface structure 104 of the scraping cylinder 3. Since the sputum adhering to the sputum suction tube is less, it can be completely collected in the storage cavity 107 after scraping and will not re-enter the human body from the through hole 106 to cause secondary pollution to the human body.

[0068] When the sputum suction is completed, the sputum suction tube is directly extracted and processed according to the subsequent conventional operation, and then the fixed cylinder 1 is taken out. The device has simple structure, convenient operation, controllable cost, increased sputum suction effect and safety, and broad prospect. Example 2

[0069] This embodiment is basically the same as example 1, the difference is that in this embodiment, as shown in Fig. 1 the guide inclined surface structure 104 is connected with a third inclined surface structure, and the inclined direction of the third inclined surface structure is upwardly inclined from the side close to the human body to the side away from the human body.

[0070] In this embodiment, the angle of the third inclined surface structure is 10°.

[0071] The sputum collected by scraping enters the storage cavity 107 through the preliminary guidance of the guide inclined surface structure. Under the guidance of the third inclined surface structure of the storage cavity 107 and the fixed cylinder 1, the sputum is guided into the bottom of the storage cavity 107, thereby reducing the problem of overflow of sputum from the through hole 106 to cause secondary infection to the human body, and improving the safety of the device in use.
