Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a sputum suction tube. Background Art

[0002] In the medical fields of critical care medicine and surgical operations, suction is a key airway management technique, especially in solving upper airway obstruction in patients with cough and sputum disorders. Suction requires timely and efficient clearing of excessive respiratory secretions to achieve the purpose of quickly restoring airway patency.

[0003] At present, a soft suction tube is usually connected to an aspirator at one end, and the other end is inserted into the patient's mouth and nose for suction. However, the main problems with suction are: 1. Since the suction tube is made of soft material, the front end cannot control the direction when it enters the mouth, and cannot guide the suction; 2. Because the suction cannot be guided, when the patient's sputum is thick or the secretions form large scabs, the small suction tube is quickly blocked and does not work, resulting in a low sputum clearance rate; 3. Patients with thick sputum usually have dry mouth. The current suction device cannot flush and suction at the same time, making the suction process extremely difficult; 4. Repeated suction will give patients a very poor suction experience, increase compliance resistance and aggravate hypoxia; 5. In emergency situations, such as when thick sputum or blood clots quickly block the glottis and cause suffocation crisis, ordinary suction tubes cannot quickly and accurately remove foreign matter.

[0004] Obviously, the current suction tubes still need to solve problems such as efficiency, comfort, and broad-spectrum applicability, which seriously affect the airway management of critically ill and postoperative patients. The low suction efficiency requires constant replacement of the suction tube, which is a huge waste of manpower costs and medical resources.

[0005] Therefore, a sputum suction tube is urgently needed to solve the above problems. Utility Model Content

[0009] To optimize the above technical solutions, the specific measures taken also include:

[0010] Furthermore, a circle of soft brushes is provided on the front section of the hard tube close to the spherical suction head.

[0011] Furthermore, the hard pipe is provided with a longitudinal crack along its entire length, and the longitudinal crack allows the main pipe to pass into or out of the hard pipe.

[0012] Furthermore, a side hole is formed on a side wall of the hard tube at one end away from the spherical suction head.

[0013] Furthermore, the outer diameter of the spherical suction head is greater than the inner diameter of the hard tube.

[0014] Furthermore, one end of the suction tube away from the main tube is connected to a suction joint, and the suction joint is used to connect to a negative pressure device.

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 As shown, a sputum suction tube of an embodiment of the utility model comprises a main pipe 1, a spherical suction head 2 and a hard tube 10, one end of the main pipe 1 is connected to the spherical suction head 2, the hard tube 10 is sleeved on the main pipe 1, the tube body of the hard tube 10 is plastically bent at an obtuse angle near the front section of the spherical suction head 2, and the other end of the main pipe 1 is forked and respectively connected to a suction tube 3 and a flushing tube 4.

[0026] The utility model sets a hard tube 10 on the main tube 1, and plastically bends the tube body of the front section of the hard tube 10 near the spherical suction head 2 at an obtuse angle, so that when in use, the hard tube 10 is pushed to the front end of the main tube 1 by using the obtuse bending structure of the front section of the hard tube 10, and the user holds the rear section of the hard tube 10 to rotate left and right, thereby adjusting and guiding the use direction of the spherical suction head 2 located in the direction of the front section of the hard tube 10, and thereby solving the problem that the main tube 1 is soft in material and the front end cannot control the direction and cannot guide the suction of sputum when entering the oral cavity; the obtuse bending structure of the front section of the hard tube 10 is also convenient for extending into the deep part of the oral cavity for suction. At the same time, the suction tube 3 and the flushing tube 4 connected in a forked shape at the other end of the main tube 1 can be used for suction through the suction tube 3 or flushing through the flushing tube 4 as needed when the device is used.

[0027] As attached Figure 2 As shown, in another embodiment, a circle of soft brushes 11 is provided on the tube body of the front section of the hard tube 10 near the spherical suction head 2. Therefore, when in use, the hard tube 10 can be slid outside the main tube 1, so that the circle of soft brushes 11 provided around the front section of the hard tube 10 can be used to clean the large scabs formed by the patient's viscous sputum or secretions; at the same time, because the hard tube 10 itself has a certain hardness, unlike the small and soft main tube 1, it can be well cleaned by the soft brush 11.

[0028] In another embodiment, a longitudinal slit 13 is provided on the entire longitudinal tube body of the hard tube 10, and the longitudinal slit 13 allows the main tube 1 to pass into the hard tube 10 for installation, or pass out of the hard tube 10 to complete the disassembly of the hard tube 10, so that the main tube 1 or the hard tube 10 can be used alone. In this way, when in use, the hard tube 10 and the main tube 1 can be disassembled and assembled as needed through the longitudinal slit 13 provided on the tube body of the hard tube 10, thereby increasing the practicality and applicability of the device.

[0029] In another embodiment, a side hole 12 is formed on the side wall of the hard tube 10 at one end away from the spherical suction head 2. Therefore, when in use, the user can hold the rear section of the hard tube 10 and the main tube 1 and press on the side hole 12 to fix the relative position of the hard tube 10 and the main tube 1, and at the same time, the rotation control of the hard tube 10 is more convenient.

[0030] In another embodiment, the outer diameter of the spherical suction head 2 is larger than the inner diameter of the hard tube 10. Therefore, when the hard tube 10 is disposed on the outer sleeve of the main tube 1, the size of the spherical suction head 2 can be used to limit the slipping of the hard tube 10, thereby avoiding the risk of the hard tube 10 slipping off.

[0031] In another embodiment, the end of the suction tube 3 away from the main tube 1 is connected to a suction connector 6, and the suction connector 6 is used to connect to a negative pressure device. The suction tube 3 is provided with an air leakage valve 5. When in use, the negative pressure suction tube of the negative pressure device can be connected through the suction connector 6. When the air leakage valve 5 is pressed to block the negative pressure environment, a negative pressure environment is formed around the spherical suction head 2, and suction can be performed; otherwise, it is connected to the atmosphere and has no suction effect.

[0032] In another embodiment, the end of the flushing tube 4 away from the main pipe 1 is connected to a flushing interface 9, and the flushing interface 9 is used to connect to a water supply device. Among them, a water bag 8 is provided on the flushing tube 4, and the water bag 8 is connected to the flushing tube 4. A buckle 7 is also provided on the flushing tube 4, and the buckle 7 is used to block or open the circulation of the flushing tube 4. When in use, the buckle 7 is opened to open the flushing tube 4, and vice versa. Among them, the flushing interface 9 is connected to the end of the infusion tube of the water supply device, and the flushing water can perform the flushing function through the water bag 8, the flushing tube 4, the main pipe 1 and the spherical suction head 2 in sequence. When the water bag 8 is squeezed, the spherical suction head 2 can pulse flushing. At the same time, when in use, the suction tube 3 can be pinched as needed, or the negative pressure device and the air leakage valve 5 can be used to maintain the pressure in the suction tube 3, so as to ensure that the flushing water flows smoothly from the flushing tube 4 into the main pipe 1 and is sprayed out from the spherical suction head 2.

[0033] The present invention sleeves the hard tube 10 on the outside of the main tube 1. When the hard tube 10 is pushed to the front end of the main tube 1, the front end of the main tube 1 moves integrally with the bend of the front section of the hard tube 10. By rotating the hard tube 10, the spherical suction head 2 can be controlled to perform directional sputum suction. The side branch at the rear end of the main tube 1 is connected to the flushing tube 4. When water is injected into the flushing tube 4 and the buckle 7 is opened, the water can be sprayed out through the main tube 1 and the spherical suction head 2 to flush and dilute the sputum in the oral cavity; when the buckle 7 is closed and the air leakage valve 5 is blocked at the same time, the main tube 1 and the spherical suction head 2 resume the suction function, thereby achieving the effect of flushing and sputum suction in one. In addition, a soft brush is provided at the front section of the hard tube 10, which can quickly wipe and clean the sputum crust near the glottis during first aid, thereby achieving high efficiency in respiratory emergency management.

[0034] The present invention can achieve the effects of directional suction of viscous and stubborn sputum, flushing and diluting suction of sputum, and cleaning of lumped foreign matter with a brush, which not only greatly improves the suction efficiency and comfort level, but also effectively improves the success rate of respiratory emergency management.

[0035] The present invention can achieve the following beneficial effects by combining the main pipe 1 and the hard pipe 10:

[0036] 1. Directional suction: When the hard tube 10 is put on the outside of the main tube 1 through the longitudinal slit 13, the hard tube 10 is pushed to the front end of the main tube 1, and the side hole 12 is held. The front end of the main tube 1 is integrated with the hard tube 10. The front end of the hard tube 10 determines the directional position of the spherical suction head 2, which is convenient for directional suction; 2. Improved comfort of sputum suction: When the patient has dry mouth and thick sputum deep in the mouth, and needs to be rinsed and suctioned at the same time, the suction connector 6 is connected to the hospital's negative pressure suction tube, and the flushing interface 9 is connected to the bagged flushing water infusion tube or the syringe, and the buckle 7 is opened, and the flushing water can be sprayed out by the ball suction 2. After flushing, close the buckle 7 and press the sealing leak valve 5 at the same time, which can apply negative pressure to the main pipe 1 and suction the ball suction head 2. This flushing process not only flushes and dilutes the thick sputum and secretions in the patient's mouth, making the sputum easier to suck out, but also relieves the patient's dry mouth and foreign body sensation in the mouth; 3. Improved sputum suction efficiency: Because the above process can suction and flush sputum in a targeted manner, the sputum suction efficiency is more accurate and efficient; 4. Suitable for emergency mode: With the assistance of a visual laryngoscope, if a large piece of sputum crust or thick sputum is found near the glottis, the finger pulse oxygen saturation has dropped sharply. At this time, the hard tube 10 can be directly inserted into the patient's mouth, and the foreign matter at the glottis can be wiped out with a soft-bristle brush 11, or the hard tube 10 can be put on the outside of the main tube 1 to wipe and attract at the same time; 5. In addition to combined use, the present invention can also be disassembled and used to cope with different usage scenarios and exert different adaptive effects according to actual surgical or medical needs.

[0037] In actual use, the manufacturer of the utility model can complete the bending plasticity of the hard tube 10 and the integral connection of the main tube 1 and other components. The application process of the multifunctional sputum suction tube of the utility model is described as follows:

[0038] Before using the device of the utility model, the suction joint 6 is connected to the hospital negative pressure suction tube, the flushing interface 9 is connected to the bagged flushing water infusion tube or the syringe, and the buckle 7 is in a closed state.

[0039] Taking patients with thick sputum that is difficult to cough up after surgery as an example, when it is necessary to suction sputum deep in the patient's mouth in a directed manner, the hard tube 10 is put on the outside of the main tube 1 through the longitudinal slit 13 and pushed to the front end of the main tube 1. Due to the presence of the spherical suction head 2, the front end of the hard tube 10 will not slip out of the front end of the main tube 1. At this time, by holding the side hole 12, the relative position of the hard tube 10 and the internal main tube 1 can be firmly fixed together, which is convenient for integrated movement. After the hard tube 10 and the spherical suction head 2 are integrated into the oral cavity, the air leakage valve 5 is pressed to apply negative pressure to the main tube 1, and suction is performed around the spherical suction head 2. Due to the bending plasticity of the front section of the hard tube 10, the hard tube 10 can be rotated left and right to achieve guided suction of sputum deep in the oral cavity.

[0040] When nasal suction is needed, the hard tube 10 and the main tube 1 can be disassembled for use, the main tube 1 can be drawn out from the hard tube 10 through the longitudinal slit 13, and the spherical suction head 2 can be carefully inserted into the nose after being coated with lubricating oil to attract secretions deep in the nasal cavity, and the remaining steps are the same as above.

[0041] When the patient has dry mouth and thick sputum deep in the mouth, and needs to be rinsed and suctioned at the same time, after the above connection, make sure that the buckle 7 is in the closed state, the flushing water is introduced through the water filling interface, squeeze the water bag 8, and the water bag 8 is filled with water during the recovery process. Open the buckle 7, squeeze the water bag 8 again, and the flushing water can be sprayed through the flushing tube 4, the main tube 1, and the spherical suction head 2. After flushing, close the buckle 7. At this time, press the sealing valve 5 to apply negative pressure to the main tube 1, and suction around the spherical suction head 2. This process dilutes the sputum and secretions on the one hand, and on the other hand, it can flush the viscous secretions in the main tube 1 and the suction tube 3, which is convenient for maintaining the patency of the suction tube.

[0042] For example, after anesthesia induction, with the assistance of a visual laryngoscope, a large piece of sputum crust or thick sputum is found near the glottis, and the blockage of the glottis by foreign matter has caused a sharp drop in the oxygen saturation of the finger pulse. At this time, the hard tube 10 can be directly inserted into the patient's mouth, and the foreign matter in the glottis can be directly wiped out with a soft brush 11. The hard tube 10 can also be put on the outside of the main tube 1 while wiping and suctioning. The suction steps are the same as above and will not be repeated. In this way, the patency of the glottis can be quickly restored to ensure smooth intubation and ventilation.

It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should be regarded as the protection scope of the utility model.
