Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an oral retention type saliva suction drainage tube. Background Art

[0002] At present, saliva suction tubes are often needed in the treatment of oral diseases. By using a saliva suction tube for single suction, oral secretions can be cleared in time, the treatment area can be seen clearly, and aspiration can be prevented. The contact end of the saliva suction tube and the patient is made of hard material to facilitate fixed-point suction. This type of saliva suction tube cannot perform continuous negative pressure suction. If the suction time is too long or the suction is limited to a certain part of the oral mucosa, iatrogenic mucosal damage is very likely to occur.

[0003] In addition, for patients in clinical coma, oral or nasal intubation, and tracheotomy who are receiving advanced airway management, the placement of the endotracheal tube will obstruct the glottis. There is a decrease in physiological airway protection, such as effective coughing mechanism, swallowing difficulties, and increased oral secretions. This interference will disrupt the natural discharge of secretions through physiological pathways, and comprehensively lead to the occurrence of aspiration VAP (Ventilator associated pneumonia). At this time, the sputum suction technique can be used to attract secretions from the nasal cavity and large airway secretions. The purpose of attracting secretions from the oral and nasal cavity is to effectively prevent oral infection and prevent aspiration pneumonia caused by secretions falling into the airway. However, conventional oral suction or endotracheal suction focuses on attracting sputum that has already formed in the airway. Due to the placement of the endotracheal tube, there is a decrease in physiological airway protection, swallowing difficulties, and increased oral secretions. The effect of gravity causes oral secretions to continue to fall. The disappearance or decrease of the cough reflex in some patients further creates the risk of falling into the airway, resulting in suctioning and not being able to eliminate the hidden aspiration caused by the secretions falling through the endotracheal tube. Therefore, it is necessary to move the clinical nursing quality control forward. Artificial airway patients have emphasized routine oral suction of secretions, that is, regular use of suction tubes to suction patients' oral secretions to prevent the secretions from falling and causing VAP. However, due to the intensity of clinical nursing, observation and evaluation, and the individual physiological conditions of patients, it is difficult to have secretions suctioned at any time. The clinic has realized the seriousness of this problem. In the prior art, endotracheal intubation through subglottic suction is often used to deal with this problem. However, due to the lack of visibility of conventional subglottic suction, and the problem of residual secretions in the subglottic suction channel after each suction, the residual secretions fall rapidly when the negative pressure drainage device is disconnected, and regular suction cannot effectively solve this problem. Moreover, it is difficult to completely suck out the secretions that have reached the subglottic area due to the dual influence of the patient's body position and the subglottic suction opening. This measure is not easy to control, and the contraction and relaxation of the airway during the suction process will also cause some secretions to fall faster.

[0004] In summary, a saliva suction drainage tube is needed to solve the risk of aspiration of oral secretions caused by the accumulation and retention of oral secretions in patients, as well as the problem of mucosal damage during oral suction. Summary of the invention

The drainage strip 2 can be prevented from slipping into the patient's mouth or being sucked into the drainage tube 1 by negative pressure.

[0056] Please refer to Figure 1 The cross section of the joint pipe 3 can be set to a circular ring. The outer wall of the joint pipe 3 can be provided with at least one step, so that the outer wall of the joint pipe 2 can at least match and connect two negative pressure pipes of different diameters.

[0057] The inner diameter of the drainage tube 1 can be set to 1 cm, and the length can be set to 20 cm. The length of the drainage strip 2 can be set to 8 cm. The length of the drainage end 210 can be set to 5 cm, that is, the length of one end of the drainage strip 2 extending out of the drainage tube 1 is 5 cm.

[0058] The negative pressure device can be set as a negative pressure aspirator, the other end of the drainage tube 1 is connected to the negative pressure tube of the negative pressure aspirator through the joint tube 3, the drainage end 210 extending from one end of the drainage tube 1 is placed in the patient's oral cavity, and the negative pressure aspirator can generate a continuous negative pressure aspiration effect of 10-20kpa. The drainage strip 2 made of soft cotton yarn has good water absorption and the continuous low negative pressure generated by the negative pressure aspirator can be used to attract the patient's oral secretions in the first time, and the softness of the drainage strip 1 makes it easy to deform, avoiding iatrogenic mucosal damage to the oral mucosa; that is, through the capillary phenomenon of the cotton yarn strip, the siphon principle combined with low negative pressure aspiration, clinical problems can be comprehensively and effectively solved.

[0059] In actual applications, in patients with clinical coma, oral or nasal endotracheal intubation, and tracheotomy who are receiving advanced airway management, the placement of the endotracheal tube will obstruct the glottis, and there will be a decrease in physiological airway protection, such as effective coughing mechanism, swallowing disorders, and increased oral secretions. This interference will destroy the natural discharge of secretions through physiological pathways, and comprehensively lead to the occurrence of aspiration VAP. When using the oral retention saliva suction drainage tube of this embodiment, after the patient is intubated through the mouth or nose, a soft cotton yarn strip is placed in the patient's mouth as the drainage end 210 of the drainage strip 2. When placing, the position of the drainage end 210 of the drainage strip 2 can be adjusted in combination with the patient's body position. For example, when the patient is in a supine position, the drainage end 210 is placed in the oropharynx; when the patient is in a lateral position, the drainage end 210 is placed in the lower cheek. At this time, it should be noted that only the drainage end 210 of the drainage strip 2 made of exposed cotton yarn is placed in the oral cavity, and the drainage tube 1 cannot be placed in the oral cavity. Then turn on the negative pressure device, adjust the negative pressure to 10-20kpa, connect the negative pressure tube to the drainage tube 1, place the tube fixing piece 110 of the drainage tube 1 on the patient's mouth, fix the fixing belt 220 on the patient's head, and adjust the tightness of the fixing belt 220 to prevent it from falling off. Then the amount of drainage fluid, the position of the drainage strip 2 and the pressure of the negative pressure aspirator can be observed, and the position of the drainage strip 2 can be dynamically adjusted according to the patient's body position. In clinical practice, observe the drainage effect and whether there is oral secretion retention. When the drainage strip 2 is covered with sputum crust, the drainage tube 1 for saliva suction should be replaced in time. Under normal circumstances, the drainage tube 1 for saliva suction is replaced every 4-6 hours to reduce the reproduction of bacterial flora.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
