Description

Technical Field

[0001] The present application relates to the technical field of sputum suction equipment, and in particular to a sputum suction device for deep sputum suction. Background Art

[0002] A sputum suction device refers to a device that uses the principle of negative pressure to suction sputum and provide oral care for the wounded and sick. It is suitable for military combat rescue and medical treatment as well as timely suction of respiratory mucus in hospitals or homes.

[0003] Some existing sputum suction devices are mainly composed of a main unit, a sputum storage chamber and a sputum suction tube. When in use, the sputum suction tube is connected to the sputum storage chamber, and then the other end of the sputum suction tube is inserted into normal saline, and negative pressure is generated between the main unit and the sputum storage chamber, so that the normal saline is sucked by the sputum suction tube (this step is used to judge the quality of the sputum suction tube and screen whether there is a gap in the sputum suction tube). Then, the main unit is stopped, and the other end of the sputum suction tube is inserted into the throat (or deeper) of the injured person. Then, negative pressure is generated through the main unit and the sputum storage chamber, so that negative pressure is synchronously generated in the sputum suction tube, and sputum in the throat is sucked, so that the sputum enters the sputum storage chamber. When the sputum suction is completed, the main unit is turned off, and the sputum suction tube is gradually pulled out. Finally, the other end of the sputum suction tube is inserted into the normal saline again, and negative pressure is generated between the main unit and the sputum storage chamber again, so that the normal saline is sucked by the sputum suction tube (this step is used to flush the sputum in the sputum suction tube). Through the above actions, the sputum suction operation is completed.

[0004] However, in the process of the suction tube being withdrawn from the patient's throat, sputum will adhere to the outer wall of the tube. As the suction tube moves, this part of the sputum is likely to come into contact with the patient's mouth and be scraped off and retained. At the same time, in the process of the suction tube being withdrawn, the patient's throat is prone to swallowing due to the movement and detachment of the suction tube, which makes the sputum scraped off and retained prone to secondary sputum intake, thereby affecting the suction effect. Summary of the invention

[0005] The present application proposes a sputum suction device for deep sputum suction, which has the advantage of reducing the probability of secondary sputum entry into the outer wall of the suction tube, and is used to solve the problem that sputum enters the throat of the injured and sick for the second time, resulting in the affected suction effect.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a sputum suction device for deep sputum suction, comprising: a main unit, a sputum storage chamber is fixedly installed at the upper position of the main unit, an air suction end of the main unit is connected with the sputum storage chamber, a sputum suction tube is arranged on one side of the sputum storage chamber, one end of the sputum suction tube is connected with the air suction port of the sputum storage chamber, and the other end of the sputum suction tube is used to extend into the throat of the injured person;

[0007] A contact piece is sleeved on the outer side of the suction tube, the end of the contact piece facing away from the sputum storage chamber is a tapered end, the inner diameter of the end of the contact piece facing the sputum storage chamber is larger than the inner diameter of the end of the contact piece facing away from the sputum storage chamber, the inner diameter of the end of the contact piece facing away from the sputum storage chamber is larger than the diameter of the suction tube, and notches are equidistantly arranged inside the contact piece and at the tapered end of the contact piece, and the notches are located on the outer side of the suction tube.

[0008] Furthermore, arc blocks are fixedly installed on the outer wall of the contact piece at equidistant intervals in the circumferential direction corresponding to the position of the tapered end of the contact piece.

[0009] Furthermore, a sleeve is sleeved on the outer side of the contact piece at a position away from the tapered end of the contact piece, a motor is fixedly installed on the outer side of the sleeve and close to the tapered end of the contact piece, a power wheel is fixedly installed on the output shaft of the motor, a swivel is rotatably installed inside the contact piece and at a position corresponding to the power wheel, the inner diameter of the swivel is larger than the diameter of the sputum suction tube, the swivel is located on the outer side of the sputum suction tube, a sliding socket is provided on the outer side of the contact piece and at a position corresponding to the power wheel, the opening of the sliding socket faces the outer side of the contact piece and the sleeve, the outer side of the swivel extends out of the sliding socket, the power wheel extends into the sliding socket and contacts with the outer side of the swivel, an inclined rod is fixedly installed equidistantly around the side of the swivel facing away from the sputum storage chamber, the inclined rod is located on the inner side of the contact piece, and one end of the inclined rod contacts with the outer side of the sputum suction tube.

[0010] Furthermore, a card slot is symmetrically opened on one side of the contact piece facing the sputum storage chamber, the opening of the card slot faces the sputum storage chamber, and a card block is fixedly installed on the inner side surface of the shell and corresponds to the position of the card slot, and the card block forms an active card connection with the card slot.

[0011] Furthermore, the circumferential outer side of the power wheel is provided with a rubber structure, and the power wheel forms an extrusion contact with the outer side surface of the rotating ring.

[0012] Furthermore, one end of the inclined rod facing away from the rotating ring is tilted inwardly, and the end of the inclined rod facing away from the rotating ring contacts the outer side surface of the sputum suction tube.

[0013] Furthermore, a support rod is fixedly installed on the inner side of the oblique rod, and the inner end of the support rod is in contact with the outer side surface of the sputum suction tube.

[0014] Furthermore, the contact piece, arc block, swivel, inclined rod and support rod are all made of medical plastic materials.

[0015] This application has the following beneficial effects:

[0016] The present application provides a suction device for deep sputum suction. Through the provision of a contact piece and a notch, the contact piece is extended into the mouth of an injured person. Thereafter, the suction tube extended into the mouth of the injured person passes through the contact piece and the notch and is extended into the throat of the injured person. Through the above-mentioned action, when the suction tube is subsequently withdrawn, it will not contact the mouth of the injured person, thereby making it difficult for sputum on the outer wall of the suction tube to be scraped and retained in the mouth of the injured person. At the same time, the swallowing action of the injured person will not cause the sputum on the outer wall of the suction tube to be sucked in again, thereby reducing the probability of affecting the suction effect.

[0017] Through the arrangement of the inclined rod and the swivel, during the above-mentioned process of pulling out the suction tube, the swivel drives the inclined rod to rotate, so that the end of the inclined rod moves in circumferential contact with the outer wall of the suction tube, causing part of the sputum on the outer wall of the suction tube to be scraped off by the inclined rod and wrapped around the inclined rod. Through this action, the probability of sputum on the outer wall of the suction tube falling into the external environment is reduced, making the external medical environment less susceptible to contamination.

[0018] Through the arrangement of the inclined rod and the suction tube, since the end of the inclined rod is in contact with the outer wall of the suction tube, when the suction tube is pulled out at a faster speed, the outer wall of the suction tube is likely to exert a force on the inclined rod, prompting the inclined rod to further contact the suction tube and play a certain speed-limiting role on the suction tube. Through the above-mentioned actions, the probability of the medical staff misoperating and causing the suction tube to be pulled out at a faster speed is reduced, making the suction effect less likely to be affected.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Embodiment 1

[0030] See also Figure 1 and Figure 2 A sputum suction device for deep sputum suction comprises a main unit 1, a sputum storage chamber 2 is fixedly installed at the upper position of the main unit 1, the air suction end of the main unit 1 is connected with the sputum storage chamber 2, a sputum suction tube 3 is arranged on one side of the sputum storage chamber 2, one end of the sputum suction tube 3 is connected with the air suction port of the sputum storage chamber 2, the other end of the sputum suction tube 3 is used to extend into the throat (or deeper) of the injured person, a contact piece 4 is sleeved on the outer side of the sputum suction tube 3, the end of the contact piece 4 facing away from the sputum storage chamber 2 is a tapered end, the inner diameter of the end of the contact piece 4 facing the sputum storage chamber 2 is larger than the inner diameter of the end of the contact piece 4 facing away from the sputum storage chamber 2, the inner diameter of the end of the contact piece 4 facing away from the sputum storage chamber 2 is larger than the diameter of the sputum suction tube 3, and a notch 5 is equidistantly penetrated in the interior of the contact piece 4 and at its tapered end, and the notch 5 is located at the outer side of the sputum suction tube 3.

[0031] When in use, the other end of the suction tube 3 is inserted into the saline solution, and a negative pressure is generated between the main unit 1 and the sputum storage chamber 2, so that the saline solution is sucked by the suction tube 3 (this step is used to judge the quality of the suction tube 3), then, the main unit 1 is shut down, and at the same time, the tapered end of the contact piece 4 is inserted into the mouth of the patient (the tapered end of the contact piece 4 is provided to support the patient's mouth, so as to prevent the patient from unconsciously closing his mouth, which affects the insertion and withdrawal of the suction tube 3), then, the other end of the suction tube 3 is gradually passed through the contact piece 4 and the notch 5, and then inserted into the throat (or deeper) of the patient, after which a negative pressure is generated through the main unit 1 and the sputum storage chamber 2, so that a negative pressure is simultaneously generated in the suction tube 3, and the sputum in the throat is sucked, so that the sputum enters the sputum storage chamber 2, when the sputum suction is completed, the main unit 1 is turned off, and the suction tube 3 is gradually pulled out, in this process, the sputum adhered to the outer wall of the suction tube 3 passes through the contact piece 4 and the notch 5 synchronously with the suction tube 3 The notch 5 is a curved surface structure at the conical end of the contact piece 4, and the sputum has a certain viscosity, so that when the sputum suction tube 3 is withdrawn, the sputum adhered to the outer wall of the sputum suction tube 3 is more easily guided by the notch 5, and then enters the contact piece 4 along the gap between the notch 5, the contact piece 4 and the sputum suction tube 3), and then moves to the external environment. Through the above-mentioned action, the sputum suction tube 3 will not contact the mouth of the patient when it is withdrawn, so that the sputum on the outer wall of the sputum suction tube 3 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 sputum suction tube 3 for the second time (because the sputum is inside the contact piece 4), thereby reducing the probability of the sputum suction effect being affected. Finally, the other end of the sputum suction tube 3 is inserted into the saline solution again, and the host 1 and the sputum storage chamber 2 generate negative pressure again, so that the saline solution is sucked by the sputum suction tube 3 (this step is used to flush the sputum in the sputum suction tube 3). Through the above-mentioned action, the sputum suction operation is completed.

[0032] See also Figure 2 The outer wall of the contact piece 4 is fixedly provided with arc blocks 6 at equal intervals in the circumferential direction corresponding to the position of the tapered end thereof.

[0033] By setting the arc block 6, when the tapered end of the contact piece 4 is inserted into the mouth of the patient, the patient can close his mouth by himself and bite the arc block 6 by teeth, thereby fixing the contact piece 4, so that the contact piece 4 does not need extra manpower to hold, thereby improving the convenience of using the device.

[0034] Embodiment 2

[0035] See also Figure 1-Figure 6This embodiment is a further improvement of the first embodiment, and the improvement lies in that: a sleeve 7 is sleeved on the outer side of the contact member 4 away from its tapered end, a slot 8 is symmetrically provided on the side of the contact member 4 facing the sputum storage chamber 2, and the opening of the slot 8 faces the sputum storage chamber 2. A block 9 is fixedly installed on the inner side of the sleeve 7 and corresponds to the position of the slot 8. The block 9 forms a sliding connection with the slot 8. A motor 10 is fixedly installed on the outer side of the sleeve 7 and close to the tapered end of the contact member 4. A power wheel 11 is fixedly installed on the output shaft of the motor 10. The circumferential outer side of the power wheel 11 is a rubber structure, and a swivel 1 is rotatably installed inside the contact member 4 and corresponds to the position of the power wheel 11. 2, the inner diameter of the swivel 12 is larger than the diameter of the sputum suction tube 3, the swivel 12 is located at the outer side of the sputum suction tube 3, a sliding socket 13 is provided on the outer side of the contact piece 4 and at the position corresponding to the power wheel 11, the opening of the sliding socket 13 faces the outer side of the contact piece 4 and the sleeve 7, the outer side surface of the swivel 12 extends out of the sliding socket 13, the power wheel 11 extends into the sliding socket 13, and forms an extrusion contact with the outer side surface of the swivel 12, and an inclined rod 14 is fixedly installed equidistantly on the side of the swivel 12 facing away from the sputum storage chamber 2, the inclined rod 14 is located at the inner side of the contact piece 4, and the end of the inclined rod 14 facing away from the swivel 12 is inclined inwardly, and the end of the inclined rod 14 facing away from the swivel 12 contacts the outer side surface of the sputum suction tube 3.

[0036] In the process of extracting the sputum suction tube 3, the motor 10 drives the power wheel 11 to rotate, so that the swivel ring 12 drives the inclined rod 14 to rotate, and then the end of the inclined rod 14 is moved in a circumferential contact with the outer wall of the sputum suction tube 3, so that the sputum on the outer wall of the sputum suction tube 3 is scraped off by the inclined rod 14 and wrapped around the inclined rod 14 (since the sputum has a certain viscosity, when the sputum contacts the end of the inclined rod 14, part of the sputum will adhere to the end of the inclined rod 14, and at the same time, through the rotation of the inclined rod 14, the adhered sputum is pulled by the inclined rod 14 and gradually wrapped around the inclined rod 14, while the rest of the sputum that is not adhered to the inclined rod 14 is guided by the rotating inclined rod 14, thereby causing this part of the sputum to be scraped off by the inclined rod 14). The sputum is spirally coiled on the outer wall of the sputum suction tube 3. The above-mentioned action of dispersing the sputum reduces the probability of the sputum adhering to the outer wall of the sputum suction tube 3 accumulating together, thereby reducing the probability of the sputum falling into the external environment. This action reduces the probability of the sputum on the outer wall of the sputum suction tube 3 falling into the external environment, making the external medical environment less susceptible to pollution. At the same time, since the end of the inclined rod 14 facing away from the swivel 12 is inclined inwardly and contacts the outer wall of the sputum suction tube 3, when the sputum suction tube 3 is withdrawn at a faster speed, the outer wall of the sputum suction tube 3 can easily exert a force on the inclined rod 14 (the contact friction between the two), prompting the inclined rod 14 to further contact the sputum suction tube 3 and exert force on the sputum suction tube 3. The sputum suction tube 3 is pulled outward quickly, and the sputum suction tube 3 is pulled outward quickly, and the sputum suction tube 3 is pulled outward quickly. The ... The sputum is not easy to affect the friction resistance between the two. In addition, slowly pulling out the suction tube 3 can reduce the irritation to the airway of the injured person and reduce the discomfort such as difficulty breathing caused by rapid pulling out. At the same time, slow pulling out can also avoid excessive friction between the suction tube 3 and the airway mucosa, thereby reducing the risk of mucosal damage and bleeding). In addition, since the inclined rods 14 arranged equidistantly around the circumference contact the outer wall of the suction tube 3, the suction tube 3 is supported to a certain extent, which promotes the existence of approximately the same spacing between the suction tube 3 and the tapered end of the contact piece 4, thereby reducing the probability of the tapered end of the contact piece 4 scraping the sputum on the outer wall of the suction tube 3 when the suction tube 3 is pulled out, thereby further reducing the influence on the suction effect.

[0037] The contact piece 4, the arc block 6, the rotating ring 12 and the inclined rod 14 are all made of medical plastic materials.

[0038] The above structure is easy to assemble and disassemble, so that the above structure in direct contact with the patient can be directly discarded after use. When suction operation is needed again, the new structure is connected to the sleeve 7 to improve the safety of use.

[0039] Embodiment 3

[0040] See also Figure 1-Figure 6 This embodiment is a further improvement of the second embodiment, and the improvement lies in that a support rod 15 is fixedly installed on the inner side of the inclined rod 14, the support rod 15 and the inclined rod 14 are arranged perpendicular to each other, the inner end of the support rod 15 contacts the outer side of the sputum suction tube 3, and the support rod 15 is made of medical plastic material.

[0041] By providing the support rod 15 , the contact area between the inclined rod 14 and the outer wall of the sputum suction tube 3 is indirectly increased, so that more sputum is forced to separate from the sputum suction tube 3 , and at the same time, the speed limiting effect on the sputum suction tube 3 being withdrawn is improved.
