Description
Technical Field
The invention belongs to the technical field of magnetic related medical equipment, relates to a sputum aspirator, and in particular relates to a magnetic coupling transmission sputum aspirator.
Background
Sputum aspiration in an artificial airway is an important care measure to save critically ill patients. Most critical patients cannot finish spontaneous cough and sputum excretion, and complicated lung inflammation, and are easy to cause serious conditions such as respiratory tract obstruction, respiratory failure and the like. The secretion in the respiratory tract is cleared in time, the lung ventilation and ventilation functions of the patient are increased, the life quality of the patient can be effectively improved, the death rate is reduced, the prognosis is improved, and the nursing operation is one of indispensable nursing operations for critical patients. At present, sputum aspiration operation of critical patients is manually operated by nurses, and the sputum aspiration operation of each patient is carried out 3-8 times per hour, which clearly increases the working intensity of nurses, prevents synchronous operation of other important nursing operations and is not beneficial to comprehensive management of critical patients. Therefore, there is a great need for a mechanical, automated, and intelligent sputum aspirator that assists or replaces a nurse in performing sputum aspiration.
The sputum aspirator of chinese patent CN106039428A and CN105816925A adopts the driving and transmission modes of the manipulator and the linear guide rail, respectively, so as to complete the feeding and retraction of the sputum aspirator. The key technology in the above patent is a movement unit for conveying the sputum aspirator tube. However, in the above patent, the device for grasping the sputum aspirator is ideal, the smooth material of the sputum aspirator is omitted, the success rate of tube feeding is difficult to ensure, and the rotation of tube withdrawal is difficult to be effectively completed. This will directly affect the subsequent operation. Therefore, for the core operation of feeding and retracting the sputum aspirator in the artificial airway sputum aspirator operation, a structure capable of ensuring the delivery of the sputum aspirator is urgently needed.
Magnetic forces and magnetic materials have since been found to play a great role in various fields of human production and life, no exception being taken in the medical field. With the development of scientific technology, magnetic related technology is also beginning to be gradually applied to the field of medical equipment. The non-contact force of the magnet, as one of its advantages, can replace some conventional fixed structure devices. The magnetic coupling transmission technology is characterized in that the driving and the transmission are not hard linked, but the transmission function is achieved through the interaction between the magnets. The magnetic coupling transmission device is generally mainly composed of three parts, namely an inner magnetic ring, an isolation sleeve and an outer magnetic ring, wherein magnetic shoes are uniformly arranged on the inner magnetic ring and the outer magnetic ring. For example, a common magnetic coupling transmission device drives an outer magnetic ring to rotate by a motor, and a magnet of an inner magnetic ring and the outer magnetic ring synchronously rotate under the action of a magnetic field of the magnet of the outer magnetic ring, so that non-contact power transmission is realized. The advantages of the non-contact transmission technology applied to the sputum aspirator are as follows: 1. the stability and the safety of the feeding of the sputum suction tube are ensured, and when the resistance of the feeding tube is smaller than the magnetic coupling transmission force, the device can stably feed the tube; when the resistance of the pipe feeding is larger than that of the magnetic coupling transmission, the pipe feeding cannot be carried out by the device, and the transmission mode avoids the overlarge force of the pipe feeding and the damage to the air passage. 2. Is convenient to detach, sterilize and clean.

Examples
What needs to be further explained is: the operation of using the magnetic coupling driving sputum aspirator to conduct the artificial airway is mainly divided into the following steps:
first: fixing a sputum suction channel: because of mechanical ventilation, critical patients need trachea cannula to establish an artificial airway. The magnetic coupling transmission sputum aspirator is used to replace manual sputum aspiration operation, and the butt joint of a machine and an artificial airway is completed first. Firstly, a shell of the sputum aspirator is opened, an endotracheal tube and a closed sputum aspirator are respectively arranged at the front and the back of a shell of the sputum aspirator, the endotracheal tube and the sputum aspirator are respectively connected with the sputum aspirator, a manual rubbing is carried out on the outer sleeve of the closed sputum aspirator, the end of the sputum aspirator is clamped between two rollers, and the shell is closed. Realize the connection of the sputum suction channel. Because the closed sputum suction tube is provided with an oxygen channel, mechanical ventilation is not affected in the sputum suction process.
Second,: parameters are set, and sputum aspiration is completed: and selecting proper sputum sucking parameters (such as the speed, the depth, the interval time and the like of a tube conveying) at the control end, and starting a sputum sucking program. After the device is started, the motor drives the inner rotor to rotate, and the outer rotor rotates under the action of magnetic force due to the action of the magnetic field, so that the upper roller is driven to move, and the sputum aspirator tube is conveyed. When the sputum suction pipe is sent to the appointed position of the airway, the negative pressure is automatically started, and the sputum suction is completed after the sputum suction pipe is retracted. The above operations are repeated according to the time interval. Because the closed sputum aspirator Guan Ke is repeatedly used, the sputum aspirator tube and the sputum aspirator device are replaced every 12 hours for each patient.
Third,: equipment disassembly, cleaning and disinfection: the device is a reusable device, and after the device is used, the contact part (mainly two rollers) of the device and the sputum suction tube needs to be cleaned and disinfected. The magnetic coupling transmission device is not rigidly connected, so that the disassembly is convenient. The device was wiped 3 times with 75% alcohol, especially at the roller site, and then sterilized with cobalt 60 radiation for the next use.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
