Description

A respiratory sputum suction device for patients with infectious diseases

technical field

The invention relates to the technical field of medical devices, in particular to a respiratory sputum suction device for patients with infectious diseases.

Background technique

Sputum suction refers to a method of sucking out the secretions of the respiratory tract through the mouth and nose to keep the respiratory tract unobstructed and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. Indications are for comatose patients, patients with a lot of sputum with the possibility of suffocation, and patients who need intratracheal administration, injection of contrast agent or dilution of sputum.

During the suction process, turn the patient's head to the operator's side, and a comatose patient can use a tongue depressor or an opener to help the patient open their mouth. Fold the end of the catheter with one hand (connecting to the glass tube) to prevent the negative pressure from adsorbing the mucous membrane and causing damage. Use the other hand to hold the head end of the suction catheter and insert it into the patient's oropharynx, step on the switch of the suction device, loosen the end of the catheter, first suck up the secretions from the oral and pharynx, and then replace the suction tube. Homeopathically insert the sputum suction tube into the trachea through the throat to a certain depth (about 15cm), pull the sputum suction tube upward from the deep part, rotate it left and right, and suck the sputum. Each suction time should not exceed 15s to avoid hypoxia of the patient. The disadvantage is that 1. The sputum is prone to overflow during the sputum suction process. The patient is a patient with an infectious disease and will spread the virus in the air, causing human-to-human transmission; 2. The sputum suction process is manually performed by medical staff. Completed, the depth and severity of the tube are all completed by the experience of the medical staff; 3. When pulling up, the suction tube needs to be rotated, and the ratio of the rotation speed and the lifting speed cannot be constant by manual operation, which may easily cause discomfort to the patient; 4 . When the patient is uncomfortable, it is necessary to manually bend the suction tube to block the negative pressure, and it is not easy to achieve complete blocking by manual operation; 5. After the suction is completed, the contaminated suction tube can only be bent section by section due to its soft material. Recycling is time-consuming and labor-intensive.

Below the two openings 15 .

In this embodiment, the first installation pipe and the second installation pipe adopt the design structure of the three-way pipe, the suction pipe enters from the second installation pipe, and passes out from one end of the first installation pipe under the action of the rotating push-pull mechanism, Then enter the second protective tube sleeve; the other port of the first installation tube can be communicated with the oxygen supply machine to provide the required oxygen for the patient. During the process of entering and exiting the suction tube, the first installation tube and the second installation tube enter the role of protection and guidance, and the first installation tube and the second installation tube also play the role of connecting the first protection sleeve and the second protection tube. The role of the casing and the oxygen tube.

As shown in FIG. 3 , FIG. 4 and FIG. 5 , the rotating push-pull mechanism 3 further includes a third installation pipe 16 , the outer wall of the third installation pipe 16 is provided with an external thread, and the inner wall of the second installation pipe 13 is provided with an inner thread The top of the second installation pipe 13 is threadedly connected to the bottom of the third installation pipe 16; the upper part of the outer wall of the third installation pipe 16 is evenly distributed with a number of transmission teeth 17; the height of the transmission teeth 17 is greater than that of the third installation pipe 16 to the box The distance from the top end surface, and the height of the transmission teeth 17 is greater than the height of the inner thread of the second installation pipe 13 and the outer thread of the third installation pipe 16;

The transmission teeth 17 mesh with the first gear 18, the first gear 18 is installed on the rotating shaft of the motor 19, the motor 19 is installed in the box 11, and the width of each tooth of the first gear 18 is smaller than that of the adjacent two transmission teeth 17. the distance between the teeth;

The central axis of the third installation pipe 16 is provided with a first guide pipe 20 that can pass through the suction pipe 1, and the first guide pipe 20 is fixed on the inner wall of the third installation pipe 16; The tube wall is provided with a third opening 21 that communicates with the inside and outside of the first guide tube 20, and a push block 22 is provided at the position of the third opening 21. The push block 22 can extend into the third opening 21, and the push block 22 is connected to the telescopic rod 23. One end of the telescopic rod 23 is fixedly connected to the inner wall of the third installation pipe 16 .

In this embodiment, the third installation tube, the first guide tube and the push block are used as execution units for pushing and lifting the sputum suction tube, and play the roles of pushing, pulling and blocking the sputum suction tube. When the suction tube needs to be pushed in, the new suction tube is pulled out from the first protective tube sleeve and passed through the first guide tube; at this moment, the forward motor and the telescopic rod are activated, and the telescopic rod pushes the suction tube On the inner wall of the first guide pipe; the motor drives the third installation pipe to rotate through the first gear and the transmission teeth, and the third installation pipe is threadedly connected with the second installation pipe. Under the restriction of the second installation pipe, the first installation pipe is Rotate and move downward, because the suction tube is fixed on the inner wall of the first guide tube by the push block at this time, the first guide tube and the suction tube are in a fixed state, and the first guide tube is driven by the third installation tube. When the third installation pipe is at the lowest position, the telescopic rod controls the push block to be away from the suction pipe, and the suction pipe is separated from the first guide rod. The guide rod and the third installation tube rotate and rise to the highest position, and then enter the process of rotating downward to complete a push cycle. Since the telescopic rod and the first guide rod are both fixed on the inner wall of the third installation pipe and are in opposite positions, the telescopic rod can enter the first guide rod through the third opening under any circumstances. When the sputum suction tube needs to be lifted, push the third installation tube to the lowest position, the push block fixes the sputum suction tube and the first guide tube, and then rotates up to complete the extraction process. When it is found that the patient has symptoms of discomfort, the motor stops working immediately, and the telescopic rod pushes the push block to block the suction tube to avoid harming the patient. Since the gap between the transmission teeth is larger than the tooth width of the first gear, the first gear plays a role similar to a lever, which can not only avoid the phenomenon of tooth jamming caused by the downward rotation, but also play a role in the design of the number of teeth. The role of the geared motor. The top end surface of the box body and the upper end surface of the second installation pipe play the role of the lifting limit of the third installation pipe.
