Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an automatic sensing alarm endotracheal tube for surgery. Background Art

[0002] Endotracheal tube is a medical device that is inserted into the trachea and / or bronchus of a patient to create a temporary artificial breathing channel for the patient, especially for patients who cannot breathe independently. Endotracheal intubation and mechanical ventilation are emergency means to rescue critically ill patients who have respiratory and cardiac arrest due to various reasons. It is an important method to maintain the patient's breathing and ensure the blood oxygen supply of important organs.

[0003] The number of children with otolaryngology is increasing day by day, especially those with adenoids and tonsils who need surgical intervention. Pediatric patients are very prone to hypoxia, and the whole operation requires general anesthesia, endotracheal intubation and assisted ventilation. Otolaryngology surgery requires the placement of supporting laryngoscopes and other tools. In order to facilitate the operation, the endotracheal tube cannot be fixed firmly with conventional adhesive tape and dental pads. During the operation, the child's head and face need to be covered with surgical disinfection towels, and it is impossible to observe whether the tube is out of place in time. Due to the interference of surgical operations, the endotracheal tube is very easy to fall out and cannot be found in time. Some of them will even fall out of the trachea completely and need to be re-intubated urgently. Once the endotracheal tube slips clinically, it will cause self-injury again, such as respiratory damage after re-intubation, prolonged treatment time, irreversible hypoxia in the brain, and even cause the death of the patient. The existing technology is to fix a temperature sensor on an ordinary endotracheal tube. When the temperature sensor cannot sense the temperature, the alarm sounds an alarm. However, the temperature sensor and the alarm need to be connected with a wire, which is easy to pull the wire during the operation, which is inconvenient to operate. Summary of the invention

[0004] The utility model aims at the above problems, makes up for the deficiencies of the prior art, and provides an automatic sensing alarm endotracheal tube for surgery to solve the problems in the above background technology.

[0005] The technical solution of the utility model is: an automatic induction alarm for surgical tracheal tube, comprising a tube body, an alarm body bonded under the tube body, a permanent magnet movably connected under the alarm body, a soft pad bonded under the permanent magnet, the soft pad bonded to the lower lip, the tube body, the alarm body, the permanent magnet and the soft pad fixed together by an annular fixing tape, and a magnetic sensor and an alarm are arranged on the alarm body;

[0006] When the alarm body and the permanent magnet are separated, the alarm sends out an alarm signal.

[0007] Furthermore, the soft pad is made of silicone.

[0008] Furthermore, an adhesive is provided under the cushion, and the adhesive is a double-sided adhesive.

[0009] Furthermore, the double-sided adhesive tape is anti-allergic double-sided adhesive tape.

[0010] Furthermore, the magnet material of the permanent magnet is neodymium iron boron.

[0011] Furthermore, a battery is installed on the alarm body.

[0012] Furthermore, the alarm is a buzzer or a voice prompter.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The automatic sensing alarm is used for surgical endotracheal tubes. The alarm body is bonded under the tube body, a permanent magnet is movably connected under the alarm body, a soft pad is bonded under the permanent magnet, and the soft pad is bonded to the lower lip. The tube body, the alarm body, the permanent magnet and the soft pad are fixed together by an annular fixing tape. During the operation, when the alarm body is separated from the permanent magnet, an alarm will be triggered, so that medical staff can find out whether the endotracheal tube is dislocated in time when they cannot see the endotracheal tube after laying the drape during the operation, and remind the surgeon in time to avoid hypoxia and secondary intubation of children caused by complete dislocation of the endotracheal tube.

[0015] (2) The automatic sensing alarm is used for surgical tracheal tubes, and the cushion can be made of silicone material. On the one hand, silicone is relatively soft and not easy to hurt the skin. On the other hand, it can increase the friction between the cushion and the permanent magnet, making it difficult for the cushion and the permanent magnet to slip off.

[0016] (3) The automatic sensing alarm is used for surgical endotracheal tubes. The alarm is set with a buzzer or a voice prompt. When the permanent magnet is separated from the alarm body, the alarm emits a buzzer sound or a voice prompt to remind the doctor. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0021] like Figure 1 , Figure 2 As shown, in this embodiment, an automatic induction alarm for surgical tracheal tube includes a tube body 1, an alarm body 2 is bonded under the tube body 1, a permanent magnet 3 is movably connected under the alarm body 2, a soft pad 4 is bonded under the permanent magnet 3, and the soft pad 4 is bonded to the lower lip. The tube body 1, the alarm body 2, the permanent magnet 3 and the soft pad 4 are fixed together by an annular fixing tape 5, and a magnetic sensor 21 and an alarm 22 are provided on the alarm body 2;

[0022] When the alarm body 2 and the permanent magnet 3 are separated, the alarm 22 sends out an alarm signal.

[0023] The utility model has an alarm body 2 bonded under a catheter body 1, a permanent magnet 3 movably connected under the alarm body 2, a soft pad 4 bonded under the permanent magnet 3, and the soft pad 4 bonded to the lower lip, and the catheter body 1, the alarm body 2, the permanent magnet 3 and the soft pad 4 are fixed together by an annular fixing adhesive tape 5. During the operation, the alarm will be triggered when the alarm body 2 is separated from the permanent magnet 3, so that the medical staff can find out whether the tracheal tube is dislodged or not in time when the tracheal tube cannot be seen after the operation drape is laid, and the surgeon can be reminded in time to avoid the problem of hypoxia and secondary intubation of children caused by the complete dislodgment of the tracheal tube.

[0024] Specifically, in some embodiments of the present invention, the soft pad 4 is made of silicone material. The present invention uses silicone material for the soft pad 4. On the one hand, the silicone 4 is relatively soft and not easy to hurt the skin. On the other hand, the friction between the soft pad 4 and the permanent magnet 3 can be increased, so that the soft pad 4 and the permanent magnet 3 are not easy to slip off.

[0025] Specifically, in some embodiments of the utility model, an adhesive is provided under the soft pad, and the adhesive is a double-sided adhesive, and the double-sided adhesive is an anti-allergic double-sided adhesive. Since the operation time is relatively long, long-term sticking is easy to cause skin allergies. The utility model uses an anti-allergic double-sided adhesive to avoid the problem of skin allergies caused by the use of conventional double-sided adhesives.

[0026] Specifically, in some embodiments of the present invention, the magnet material of the permanent magnet 3 is neodymium iron boron. The magnet material of the permanent magnet 3 of the present invention is neodymium iron boron, which has a strong adsorption capacity and increases the stability of the alarm body 1.

[0027] Specifically, in some embodiments of the present invention, a battery 23 is installed on the alarm body 2. Since the power wire is easily pulled during surgery, the alarm device on the catheter body 1 is easily torn off, affecting the progress of the surgery, so the present invention uses a battery to avoid the problem of wire pulling during surgery.

[0028] Specifically, in some embodiments of the present invention, the alarm 22 is a buzzer or a voice prompter. The present invention uses a buzzer or a voice prompter alarm setting, when the alarm body 2 is separated from the permanent magnet 3, the alarm 22 emits a buzzer sound or a voice prompt to remind the doctor.

[0029] The operating principle of this utility model:

[0030] When the utility model is used, the endotracheal tube is inserted through the mouth, and the alarm body 2, the permanent magnet 3, and the soft cushion 4 are fixed in sequence under the tube body 1 at the position of the patient's lower lip by the annular fixing tape 5. The tube body 1 is bonded to the alarm body 2, the alarm body 2 is movably connected to the permanent magnet 3, the permanent magnet 3 is bonded to the soft cushion 4, and the soft cushion 4 is bonded to the lower lip. During the operation, when the alarm body 2 is separated from the permanent magnet 3, the magnetic sensor 21 senses the change in magnetic field intensity between the alarm body 2 and the permanent magnet 3, and converts the above change into an electrical signal and sends it to the alarm 22. The alarm 22 will emit a buzzing sound or a voice prompt to remind the doctor, so that the medical staff can find out whether the endotracheal tube is dislodged or shifted in time when the endotracheal tube is not visible after the operation is paved, and remind the surgeon in time to avoid the problem of hypoxia and secondary intubation of children caused by the complete dislodgment of the endotracheal tube, thereby ensuring the safety during the operation.

[0031] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in the field after reading this specification are all within the scope of protection of the present invention.
