Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to an endotracheal tube fixing and anti-dropout alarm device. Background Art
[0002] Endotracheal intubation is a technique that involves implanting a special tube into the airway through the glottis. It is used for tracheal suction, alveolar lavage, and can even be provided to patients who require airway protection. In this case, an artificial airway can be established to protect the patient's airway itself and assist the patient in mechanical ventilation.
[0003] Currently, when inserting a tracheal tube into a patient's airway, a fixed anti-dropout tube is provided to bite into the patient's mouth for oral support, and the tracheal tube is inserted into the airway through the internal pipe of the fixed anti-dropout tube. However, when the fixed anti-dropout tube of the existing technology is used, the patient may spit out the tube due to pressure after tracheal intubation, thereby causing the tracheal tube to move. Medical staff often fail to discover it in time, which affects the quality of the patient's mechanical ventilation. Therefore, to address the above problems, we have proposed a tracheal tube fixed anti-dropout tube alarm device. Utility Model Content
[0004] In view of the above problems, the purpose of the present invention is to provide a tracheal tube fixing and anti-dropping alarm device, which is equipped with a warning device. When the tracheal tube moves beyond a certain range, it will issue an alarm to promptly remind medical staff to deal with it.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tracheal intubation fixed anti-dislodgement tube alarm device, comprising a support tube, a fixed tube and a warning module, wherein the support tube is used to support the oral cavity, and a channel 1 for inserting the tracheal intubation and a channel 2 for inserting the suction tube are provided inside the support tube, a tracheal intubation is detachably installed in the fixed tube, and the fixed tube is movably installed inside the channel 1, an annular groove is provided on the inner wall of the channel 1, a magnet 1 is provided on the inner walls at both ends of the annular groove, and a magnet 2 adsorbed with the magnet 1 is provided on the outer wall of the fixed tube, and the warning module comprises a pressure sensor arranged inside the annular groove, a controller arranged on the support tube and a warning member, and the pressure sensor and the warning member are electrically connected to the controller.
[0006] The beneficial effects of the utility model are as follows: by installing the endotracheal tube in the fixed tube, and then installing the fixed tube into the first channel, the first magnet and the second magnet are attracted to each other, and the second magnet is in contact with the pressure sensor. At this time, the pressure is within the set pressure value. After the second magnet is separated from the first magnet, the pressure signal on the pressure sensor weakens or disappears and transmits the signal to the controller. The controller controls the warning part to sound an alarm, and promptly reminds medical staff to deal with it.
[0007] In order to facilitate the adjustment of the depth of endotracheal tube insertion according to different patients;
[0008] As a further improvement of the above technical solution: a thread groove is provided on the inner wall of the fixing tube, and a thread ring matching the thread groove is provided on the outer wall of the tracheal cannula.
[0009] The beneficial effect of this improvement is that the insertion depth of the tracheal tube varies from patient to patient. Therefore, before installing the fixing tube into channel 1, the fixing tube can be fixed to a suitable position by threading the fixing tube through the threaded groove and the threaded ring, so that the tracheal tube inserted into the body is of a length suitable for the patient, which is convenient for the patient to use.
[0010] In order to effectively support the oral cavity;
[0011] As a further improvement of the above technical solution: two bite rings are provided at one end of the support tube, and a bite unit is formed between the two bite rings.
[0012] The beneficial effect of this improvement is that when the support tube is placed in the patient's mouth, the patient's upper and lower teeth will be placed in the occlusal unit. At this time, the two occlusal rings limit the patient's teeth to prevent the patient's teeth from sliding on the support tube, thereby increasing the support stability of the support tube.
[0013] To reinforce the endotracheal tube;
[0014] As a further improvement of the above technical solution: a fixing screw is threadedly connected to the support tube, and one end of the fixing screw extends to the interior of channel one.
[0015] The beneficial effect of this improvement is that when the fixing tube drives the tracheal tube into the interior of channel one, magnet one and magnet two will fix the position of the tracheal tube in advance, and then tighten the fixing screw so that one end of the fixing screw enters the interior of channel one to fix the fixing tube.
[0016] To facilitate the use of support tubes;
[0017] As a further improvement of the above technical solution: an auxiliary portion is provided at one end of the support tube away from the bite ring.
[0018] The beneficial effect of this improvement is that when the support tube needs to be placed in the patient's mouth, by holding the auxiliary part, it is convenient to reduce the contact of the hand with the endotracheal tube and the fixed tube when inserting the fixed tube into the channel 1, and at the same time it is convenient to place the support tube accurately in the mouth.
[0019] In order to increase the stability of the support tube;
[0020] As a further improvement of the above technical solution: two reinforcement belts are symmetrically provided on one of the bite rings, and the free ends of the two reinforcement belts are connected by a connecting piece.
[0021] The beneficial effect of this improvement is that when in use, the two reinforcement belts are wrapped around the back of the head and then connected and fixed by the connector, so as to avoid accidental contact under the action of external force during surgery, which may cause the support tube to come out of the oral cavity or move.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.
[0029] like Figure 1-5As shown, a tracheal intubation fixed anti-dropout tube alarm device includes a support tube 1, a fixed tube 4 and a warning module, the support tube 1 is used to support the oral cavity, the support tube 1 is provided with a channel 2 for inserting the tracheal intubation tube 5 and a channel 2 3 for inserting the sputum suction tube, the fixed tube 4 is detachably installed with the tracheal intubation tube 5, the fixed tube 4 is movably installed inside the channel 1 2, an annular groove 6 is provided on the inner wall of the channel 1 2, a magnet 7 is provided on the inner wall of both ends of the annular groove 6, a magnet 2 8 adsorbed by the magnet 1 7 is provided on the outer wall of the fixed tube 4, the warning module includes a pressure sensor 9 provided inside the annular groove 6, a controller 10 provided on the support tube 1 and a warning member 11, and the pressure sensor 9 and the warning member 11 are both electrically connected to the controller 10;
[0030] Specifically, the warning member 11 can be a warning device such as an alarm or a warning light. When it needs to be used, the fixed tube 4 is installed on the tracheal cannula 5, and then the fixed tube 4 drives the tracheal cannula 5 to be installed into the interior of channel 1 2. As the fixed tube 4 enters the interior of channel 1 2, magnet 1 7 is adsorbed by magnet 2 8, and magnet 2 8 is in contact with pressure sensor 9. This pressure sensor 9 is a pressure sensor 9 with reverse output. When the pressure sensor 9 receives the pressure signal, it outputs a specific electrical signal, which is changed into a signal state that does not trigger the warning member 11 through the reverse circuit. When the tracheal cannula 5 drives the fixed tube 4 to move, the pressure on the pressure sensor 9 disappears, and the output electrical signal is transmitted to the controller 10. The controller 10 controls the warning member 11 to issue an alarm, reminding medical staff to take timely measures to enable the patient to achieve effective mechanical ventilation. After the tracheal cannula 5, a suction tube can be inserted through channel 2 3 at any time to suck out the sputum inside the mouth to avoid blockage and choking of the patient.
[0031] Preferably, a thread groove 12 is provided on the inner wall of the fixing tube 4, and a threaded ring 13 that matches the thread groove 12 is provided on the outer wall of the tracheal cannula 5. The insertion depth of the tracheal cannula 5 is different for different patients. Therefore, before installing the fixing tube 4 into the channel 1 2, the fixing tube 4 can be fixed to a suitable position by threading the thread groove 12 and the threaded ring 13, so that the tracheal cannula 5 inserted into the body has a length suitable for the patient, which is convenient for use by the appropriate patient.
[0032] Preferably, two bite rings 14 are provided at one end of the support tube 1, and a bite unit 15 is formed between the two bite rings 14, wherein the bite ring 14 is made of rubber, silicone or other materials. When the support tube 1 is placed in the patient's mouth, the patient's upper and lower teeth will be placed in the bite unit 15. At this time, the two bite rings 14 limit the patient's teeth to prevent the patient's teeth from sliding on the support tube 1, thereby increasing the support stability of the support tube 1.
[0033] Preferably, a fixing screw 16 is threadedly connected to the support tube 1, and one end of the fixing screw 16 extends to the interior of channel 1 2. When the fixing tube 4 drives the tracheal tube 5 into the interior of channel 1 2, magnet 1 7 and magnet 2 8 will fix the position of the tracheal tube 5 in advance, and then tighten the fixing screw 16 so that one end of the fixing screw 16 enters the interior of channel 1 2 to fix the fixing tube 4.
[0034] Preferably, an auxiliary portion 17 is provided at one end of the support tube 1 away from the bite ring 14. When the support tube 1 needs to be placed in the patient's mouth, by holding the auxiliary portion 17, it is convenient to reduce the contact between the hand and the tracheal tube 5 and the fixing tube 4 when inserting the fixing tube 4 into the channel 1 2, and at the same time, it is convenient to accurately place the support tube 1 in the mouth.
[0035] Preferably, two reinforcement straps 18 are symmetrically provided on one of the occlusal rings 14, and the free ends of the two reinforcement straps 18 are connected by a connector 19, wherein the connector 19 can be a structure such as Velcro, snap fasteners, etc. When in use, the two reinforcement straps 18 are wrapped around the back of the head and then connected and fixed by the connector 19 to avoid accidental contact under the action of external force during surgery, which may cause the support tube 1 to be out of the mouth or move.
[0036] The working principle and usage process of the present invention are as follows: when using the device, the doctor first determines the appropriate depth of insertion into the patient's body according to the patient's height before performing tracheal intubation 5 on the patient, then rotates the fixing tube 4, fixes the fixing tube 4 at the appropriate position on the tracheal intubation 5, places the support tube 1 into the patient's mouth, and then places the patient's upper and lower teeth into the occlusal unit 15, and then as the tracheal intubation 5 goes deeper, the fixing tube 4 enters the interior of the support tube 1, and the magnet 1 7 and the magnet 2 8 are attracted to each other. At this time, the magnet 2 8 contacts the pressure sensor 9, and then the fixing screw 16 is twisted, and one end of the fixing screw 16 enters the channel 1 2 to resist and fix the fixing tube 4. When the fixing tube 4 is displaced and the magnet 1 7 and the magnet 2 8 are separated, there is no force on the pressure sensor 9, and the electrical signal is transmitted in reverse, and the signal is transmitted to the controller 10. The controller 10 controls the warning part 11 to issue an alarm. At this time, the medical staff observes the warning signal and finds that the tracheal intubation 5 has been displaced by a certain length, and promptly checks and handles the relevant situation.
