[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0027] As described in the background technology, the liquid medicine in the nebulizer may flow back toward the patient. This situation may be caused by a variety of factors, such as changes in the patient's body position or improper angle operation. When the liquid medicine flows back toward the patient, it may not only lead to waste of medicine, but more importantly, it may cause unnecessary health risks to the patient, such as drug overdose, inhalation of foreign matter, etc.
[0028] In order to solve this technical problem, the utility model provides an anti-backflow atomization tube.
[0029] Specifically, please refer to Figure 1-Figure 4 , the anti-backflow atomizer tube specifically includes:
[0030] The one-way conducting structure 1 is connected to an S-shaped tube 2, and the side and bottom of the S-shaped tube 2 are connected to a collecting bottle 4. The S-shaped tube 2 and the collecting bottle 4 cooperate to prevent the backflow of the liquid medicine.
[0031] The anti-backflow atomizer tube provided by the utility model has an S-shaped tube 2 and a collecting bottle 4. When the medicine liquid flows back, the medicine liquid will first enter the S-shaped tube 2 during the backflow process. Due to the curved design of the S-shaped tube 2, the medicine liquid will flow to the collecting bottle 4 under the action of gravity and inertia and be collected in the collecting bottle 4 connected thereto. Through the combination of the S-shaped tube 2 and the collecting bottle 4, the medicine liquid can be quickly and effectively collected when it flows back, thereby preventing the medicine liquid from entering the patient's body. By preventing the medicine liquid from flowing back, the medical risks caused by accidental aspiration or excessive inhalation of the medicine liquid are reduced, thereby ensuring the safety of the patient.
[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0035] Example 1, please refer to Figure 1-Figure 4 , an anti-backflow atomization tube, comprising a unidirectional conductive structure 1, an S-shaped tube 2 is connected to the unidirectional conductive structure 1, and the side and bottom of the S-shaped tube 2 are connected to a collecting bottle 4, the S-shaped tube 2 and the collecting bottle 4 are used together to achieve anti-backflow of liquid medicine, through the S-shaped tube 2 and the collecting bottle 4, when the liquid medicine flows back, the liquid medicine will first enter the S-shaped tube 2 during the backflow process, due to the curved design of the S-shaped tube 2, the liquid medicine will flow to the collecting bottle 4 under the action of gravity and inertia and be collected in the collecting bottle 4 connected thereto, through the combination of the S-shaped tube 2 and the collecting bottle 4, the liquid medicine can be quickly and effectively collected when it flows back, thereby preventing the liquid medicine from entering the patient's body, and by preventing the liquid medicine from flowing back, the medical risks caused by accidental aspiration or excessive inhalation of the liquid medicine are reduced, thereby ensuring the safety of the patient, the collecting bottle 4 is transparent, and if the liquid medicine flows back, the atomization is immediately stopped and adjusted.
[0036] The present application sets up two collecting bottles 4. When the tilt angle is less than ninety degrees, the collecting bottle 4 at the bottom collects the medicine liquid, and when the tilt angle is greater than ninety degrees, the collecting bottle 4 at the side collects the medicine liquid. The direction of the atomizing mask is toward the collecting bottle 4 at the side.
[0037] Further, such as Figure 2-Figure 3 As shown, a screw hole 402 is opened on the S-shaped tube 2, and a threaded tube 401 is threadedly connected to the inner wall of the screw hole 402. One end of the threaded tube 401 is fixedly connected to the collecting bottle 4. After the collecting bottle 4 is rotated to separate the threaded tube 401 from the screw hole 402, the collecting bottle 4 can be removed, thereby facilitating the cleaning of the collecting bottle 4.
[0038] Example 2, the anti-backflow atomizer tube provided in Example 1 is further optimized, specifically, as follows Figure 1-Figure 4As shown, the one-way conductive structure 1 includes a first shell 101 fixedly connected to one end of the S-shaped tube 2, a connecting tube 103 is inserted into the inner wall of the first shell 101, and the bottom end of the connecting tube 103 is fixedly connected to the second shell 102. This arrangement makes the second shell 102 and the first shell 101 detachable, which is convenient for cleaning and allows the whole to be reused.
[0039] Further, such as Figure 1-Figure 4 As shown, a fixing bolt 104 is threadedly connected to one side of the first shell 101, and one end of the fixing bolt 104 penetrates into the first shell 101 and contacts the connecting pipe 103. The setting of the fixing bolt 104 can fix the connecting pipe 103 and the first shell 101, and then fix the connection between the first shell 101 and the second shell 102. After loosening the fixing bolt 104, pulling the second shell 102 can separate the connecting pipe 103 from the first shell 101.
[0040] Further, such as Figure 2-Figure 3 As shown, a sealing gasket 105 is sleeved on the outer surface of the connecting pipe 103, and a groove is opened on the top of the sealing gasket 105, which is plugged into the bottom end of the first shell 101. The sealing gasket 105 can seal the connection between the first shell 101 and the second shell 102.
[0041] Further, such as Figure 2-Figure 4 As shown, the first shell 101 and the second shell 102 are both fixedly connected with a support frame 106, and a connecting rod 107 is inserted between the two support frames 106. The bottom end of the connecting rod 107 is fixedly connected with a counterweight block 109. The connecting rod 107 can be separated from the uppermost support frame 106, thereby avoiding affecting the separation of the first shell 101 and the second shell 102.
[0042] Further, such as Figure 4 As shown, a sealing plug 108 is fixedly sleeved on the outer surface of the connecting rod 107 , and the sealing plug 108 is located between the two connecting rods 107 .
[0043] Further, such as Figure 4 As shown, an inner tube 110 is provided in the first shell 101, and the inner tube 110 is for the sealing plug 108 to be inserted to achieve the blocking of the one-way conductive structure 1. When the first shell 101 is tilted, the gravity of the counterweight block 109 can drive the sealing plug 108 to move through the connecting rod 107, so that the sealing plug 108 is inserted into the inner tube 110 to block the inner tube 110 to achieve backflow prevention. The small part of the liquid medicine leaked during the non-blocking process is collected by the S-shaped tube 2 and the collecting bottle 4.
[0044] Further, such as Figure 4As shown, a sealing ring is provided on the outer surface of the sealing plug 108. The friction force between the sealing ring and the sealing plug 108 when inserted into the inner tube 110 is smaller than the gravity of the counterweight 109. This arrangement enables the gravity of the counterweight 109 to drive the sealing plug 108 to separate from the inner tube 110 when the one-way conducting structure 1 is reset from a tilted state. The setting of the sealing ring can improve the sealing performance when the sealing plug 108 and the inner tube 110 are plugged in.
[0045] Example 3, the anti-backflow atomizer tube provided in Example 1 or 2 is further optimized, specifically, as follows Figure 1 As shown, a magnet 3 is fixedly connected to the S-shaped tube 2. During installation, the one-way conductive structure 1 can be adsorbed on a hospital bed or other supporting objects through the magnet 3 to reduce the tilting of the one-way conductive structure 1. The S-shaped setting of the S-shaped tube 2 can also be suspended on a hospital bed or other supporting objects so that it can be temporarily placed during use.
[0046] The use process of the anti-backflow atomizer tube provided by the utility model is as follows:
[0047] The S-shaped tube 2 is connected to the mask, and the second shell 102 is connected to the nebulizer. The atomized medicine is transported to the patient from bottom to top through the second shell 102, the inner tube 110 and the S-shaped tube 2. When the patient's holding angle changes and causes the one-way conductive structure 1 to tip over, the backflowing medicine can be collected in the collecting bottle 4. When the tilt angle is greater than ninety degrees, the gravity of the counterweight block 109 can drive the sealing plug 108 to move through the connecting rod 107, so that the sealing plug 108 is inserted into the inner tube 110 to seal the inner tube 110 to prevent backflow. This arrangement is because when there is no blocking, the amount of medicine backflowing when the tilt angle is greater than ninety degrees is greater. Therefore, the sealing plug 108 is used to solve the problem of medicine backflow.
