Description

Technical Field

[0001] The invention belongs to the technical field of laryngoscopes, and in particular relates to a soft visual laryngoscope and an endotracheal intubation module. Background Art

[0002] The soft video laryngoscope is an advanced medical device, which is mainly used to observe the condition of the larynx and airway. The soft video laryngoscope adopts soft optical fiber and camera, and helps doctors to make accurate diagnosis and treatment by providing clear images. In the diagnosis of respiratory diseases, it can observe the condition of the vocal cords, throat, trachea and other parts, helping doctors to determine the type and extent of the disease and formulate reasonable treatment plans. It plays an important role in the diagnosis and treatment of respiratory diseases.

[0003] For example, patent publication number CN115530737B discloses a visual flexible laryngoscope with a stable connection component, including a display, a control body and an insertion part. One end of the control body is connected to the display, and the other end of the control body is connected to the insertion part. The insertion part includes a lamp head section, an outer hose, a hinge and an inner soft column. The outer hose is provided with a plurality of evenly distributed hinges, and two adjacent hinges are butted end to end. The outer hose is provided with an inner soft column. During the process of inserting the insertion part into the human body, the doctor manually presses the airbag on the control body to squeeze the gas into the trachea, and then diffuses it into a plurality of branch hoses. The insertion part can be controlled to maintain a certain hardness so that the insertion part can be smoothly inserted into the human body. Then, the insertion part is controlled to maintain the softest state to reduce the pain caused by the insertion part in the human body. The patient can make a certain degree of movement, and the soft insertion part can be deformed smoothly along with the patient's movement.

[0004] However, the conventional device still has the following problems when used:

[0005] However, when medical staff are doing throat examination, they usually need to hold the patient's mouth with one hand and hold the main end of the soft laryngoscope with the other hand, and at the same time insert the laryngoscope hose at the other end, and then place a disposable laryngoscope bite pad, and use tape to wrap the bite pad and the tube to fix it. When adjusting the intubation depth, the bite pad and the tube need to be fixed again. The steps are cumbersome and unreliable. If medical staff perform first aid on the patient in a mobile ambulance or ambulance bed, the cumbersome operation can easily delay the patient's first aid progress, and the mobile ambulance or ambulance bed is prone to bumps, and the shaking force of the laryngoscope causes the hose to shake slightly in the patient's throat, which can easily aggravate the patient's discomfort and is not conducive to the rescue of the patient.

[0036] The protective gasket 23 in the present invention has a certain degree of flexibility and elasticity and is separated from the inner wall of the insertion hose 6 by a certain distance, so that the insertion hose 6 provides a certain degree of flexible contraction after being squeezed by the patient's throat, further reducing the patient's discomfort, and the protective gasket 23 can be used to protect the structure on the fixed outer ring 25, and the protective gasket 23 is used to press and limit multiple limiting magnetic blocks 28 to the inner wall position of the mounting frame 27. When the quick stabilization mechanism is closed, the hose clamping handle 10 and the hose clamping handle 20 are pressed against the outer wall of the insertion hose 6. At this time, the limiting magnetic blocks 28 located in the insertion hose 6 are magnetically attracted and extend outward from the inner wall of the mounting frame 27 to the inner wall of the insertion hose 6, so that the quick stabilization mechanism will not slide easily when the insertion hose 6 is fixed, and the insertion hose 6 and the disposable laryngoscope tooth pad 16 can be made to move synchronously with the patient's mouth, thereby reducing the shaking rate of the insertion hose 6 in the patient's throat.

[0038] When the insertion hose 6 bends in the patient's mouth, the rotating steel ball 30 can assist the protective gasket 23 to move in a small range on the inner wall of the insertion hose 6. The flexible separation of the protective gasket 23 can meet the friction pressure generated by the deformation of the insertion hose 6, and the friction between the limiting magnetic block 28 and the protective gasket 23 is further reduced by setting the groove 33.

[0039] The working principle and use process of the present invention are as follows: In the present invention, after the medical staff guides the insertion hose 6 into the patient's mouth by holding the laryngoscope body 1, the quick stabilization mechanism is moved along the insertion hose 6 to the patient's oral cavity, and the disposable laryngoscope tooth pad 16 is taken and fitted between the tooth pad clamping handle 1 1 and the tooth pad clamping handle 2 21. Then, two fingers are pressed to pull the tooth pad clamping handle 1 1 and the tooth pad clamping handle 2 21 so that the two are closed in a ring shape, so that the disposable laryngoscope tooth pad 16 is kept fixed by using the limiting card groove 18 to clamp the tooth pad protrusion 17. At the same time, through the hinged relationship of the connecting hinge 9, the annular closure of the tooth pad clamping handle 1 1 and the tooth pad clamping handle 2 21 will synchronously drive the hose clamping handle 10 and the hose clamping handle 2 20 to be annularly closed, and multiple rubber The rubber clamping strip 22 increases the friction force so that the hose clamping handle 10 and the hose clamping handle 20 are stuck in the outer wall position of the insertion hose 6. By using this device, the insertion hose 6 and the disposable laryngoscope tooth pad 16 can be quickly and synchronously fixed to the patient's mouth, thereby speeding up the rescue of the patient. At this time, the medical staff stretches the folded hose 12 to make the folded hose 12 unfold and have deformation toughness, which provides a shock-absorbing effect for the present invention. At this time, since the insertion hose 6 and the disposable laryngoscope tooth pad 16 have been fixed in the patient's mouth, when the main body of the laryngoscope is shaken by the emergency vehicle or the ambulance bed and the medical staff holding it, it is cushioned by the deformation toughness of the folded hose 12, thereby reducing the discomfort of the patient to the bump, which is beneficial to the rescue of the patient. The protective The washer 23 has a certain degree of flexibility and elasticity and is separated from the inner wall of the insertion hose 6 by a certain distance, so that the insertion hose 6 can provide a certain degree of flexibility and contraction after being squeezed by the patient's throat, further reducing the patient's discomfort, and the protective washer 23 can be used to protect the structure on the fixed outer ring 25, and the protective washer 23 is used to press and limit multiple limiting magnetic blocks 28 to the inner wall position of the mounting frame 27. When the quick stabilization mechanism is closed, the hose clamping handle 10 and the hose clamping handle 20 are pressed against the outer wall of the insertion hose 6.

The protective gasket 23 in the present invention has a certain degree of flexibility and elasticity and is separated from the inner wall of the insertion hose 6 by a certain distance, so that the insertion hose 6 provides a certain degree of flexible contraction after being squeezed by the patient's throat, further reducing the patient's discomfort. The protective gasket 23 can be used to protect the structure on the fixed outer ring 25, and the protective gasket 23 is used to press and limit multiple limiting magnetic blocks 28 to the inner wall position of the mounting frame 27. When the rapid stabilization mechanism is closed, the hose clamping handle 10 and the hose clamping handle 20 are pressed against the outer wall of the insertion hose 6. At this time, the limiting magnetic block 28 located in the insertion hose 6 is magnetically attracted and extends outward from the inner wall of the mounting frame 27.The inner wall of the insertion hose 6 is pressed against the quick stabilization mechanism, so that the insertion hose 6 will not slide easily when it is fixed, and the insertion hose 6 and the disposable laryngoscope tooth pad 16 can move synchronously with the patient's mouth, thereby reducing the shaking rate of the insertion hose 6 in the patient's throat.
