Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a respiratory tract sputum aspirator for patients with infectious diseases.
Background
Sputum aspiration refers to a method for sucking secretion of respiratory tract through oral cavity and nasal cavity to keep respiratory tract unobstructed and prevent complications such as aspiration pneumonia, atelectasis, asphyxia, etc. The preparation is suitable for patients with coma, especially patients with the possibility of asphyxia in the sputum, and patients who need intratracheal administration, contrast medium injection or sputum dilution.
The sputum aspiration process is to turn the patient's head to the operator's side, and the comatose patient can use a tongue depressor or an opener to help the patient open his mouth. The catheter tip was folded (where the glass tube was attached) by one hand to avoid negative pressure adsorption to the mucosa, causing injury. The other hand uses the sterile holding forceps to hold the head end of the sputum suction catheter to be inserted into the oral pharynx of a patient, the switch of the aspirator is stepped on by feet, the tail end of the catheter is loosened, the secretion of the oral pharynx and the throat is sucked completely, then the sputum suction catheter is replaced, the sputum suction catheter is inserted into the trachea to a certain depth (about 15 cm) through the throat in order when the patient inhales, and the sputum suction catheter is lifted from the deep part to rotate left and right to suck the sputum. The sputum sucking time is not more than 15s each time, so that the hypoxia of the patient is avoided. The sputum suction device has the defects that 1, the condition that the sputum is overflowed easily occurs in the sputum suction process, and the patient is an infectious disease patient, so that viruses can be scattered in the air to cause people to pass; 2. the sputum suction process is completed manually by medical staff, and the depth of the tube insertion, the weight and the like are completed by the experience of the medical staff; 3. when the sputum aspirator is lifted, the sputum aspirator needs to be rotated, the proportion of the manual operation rotation speed and the lifting speed can not be constant, and the discomfort of a patient is easily caused; 4. when a patient is untimely, the sputum suction tube is required to be bent manually to block the negative pressure, and the complete blocking is not easy to realize by manual operation; 5. after the sputum suction is finished, the polluted sputum suction pipe is made of soft materials, and can be bent and recovered section by section, so that time and labor are wasted.

In the process of entering and exiting the sputum suction tube, the first mounting tube and the second mounting tube enter the protection and guide functions, and the first mounting tube and the second mounting tube also play the role of connecting the first protection sleeve, the second protection sleeve and the oxygen tube.
As shown in fig. 3, 4 and 5, the rotary pushing and pulling mechanism 3 further includes a third mounting tube 16, an outer wall of the third mounting tube 16 is provided with an external thread, an inner wall of the second mounting tube 13 is provided with an internal thread, and a top of the second mounting tube 13 is in threaded connection with a bottom of the third mounting tube 16; a plurality of transmission teeth 17 are uniformly distributed on the upper part of the outer wall of the third installation tube 16; the height of the transmission teeth 17 is larger than the distance from the third mounting tube 16 to the top end surface of the box body, and the height of the transmission teeth 17 is larger than the heights of the internal threads of the second mounting tube 13 and the external threads of the third mounting tube 16;

In this embodiment, the third mounting tube, the first guide tube and the push block function as an execution unit for pushing and lifting the sputum aspirator, and function as pushing, lifting and blocking the sputum aspirator. When the sputum suction pipe needs to be pushed in, a new sputum suction pipe is pulled out of the first protective pipe sleeve and penetrates through the first guide pipe; at the moment, a forward motor and a telescopic rod are started, and the telescopic rod pushes the sputum suction tube to the inner wall of the first guide tube; the motor drives the third mounting tube to rotate through the first gear and the driving gear, the third mounting tube is in threaded connection with the second mounting tube, the first mounting tube rotates forward and moves downwards under the limiting action of the second mounting tube, and the first guiding tube and the sputum suction tube are in a fixed state as the sputum suction tube is fixedly connected to the inner wall of the first guiding tube by the pushing block at the moment, and the first guiding tube rotates forward and moves downwards under the driving of the third mounting tube; when the third installation pipe is at the lowest position, the telescopic rod controls the push block to be far away from the sputum suction pipe, the sputum suction pipe is separated from the first guide rod, the motor is reversely rotated at the moment, the first guide rod and the third installation pipe are driven by the motor to rotate and rise to the highest position, and then the first guide rod and the third installation pipe enter a rotating downward movement process to complete one-time pushing circulation. Because telescopic link and first guide bar are all fixed at the third installation intraductal wall, and the position is relative, therefore in the telescopic link all accessible third opening gets into first guide bar under any circumstances. When the sputum suction tube is required to be lifted, the third mounting tube is pushed to the lowest position, the sputum suction tube and the first guide tube are fixed by the pushing block, and then the sputum suction tube and the first guide tube are rotated and lifted to complete the lifting process. When the discomfort symptoms of the patient are found, the motor immediately stops working, and the telescopic rod pushes the push block to block the sputum suction tube, so that the patient is prevented from being injured. Because the clearance between the transmission teeth is greater than the tooth width of the first gear, the first gear plays a role similar to a deflector rod, so that the phenomenon of tooth clamping caused by downward rotation can be avoided, and the effect of a gear motor can be achieved through the design of the number of teeth.

When the sputum suction tube is not fixed by the push block due to interference fit between the second guide tube, the third guide tube and the sputum suction tube, the sputum suction tube cannot reset due to gravity and the like. When the patient wears the mask, the position of the mounting plate in the first sliding groove is adjusted, so that the third guide tube is inserted into the nasal cavity of the patient, and the required oxygen is provided for the patient while the sputum suction tube is guided.
