Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, in particular to an airway unblocking device for critical medical respiratory support. Background Art
[0002] Foreign bodies in the trachea and bronchi are one of the common causes of sudden airway obstruction. After foreign bodies or food are accidentally inhaled into the trachea, the patient will experience sudden spasmodic choking, coughing, hoarseness, shortness of breath and sputum. Severe cases can cause mucosal edema, luminal stenosis, inability to expel alveolar gas and secondary emphysema. Large foreign bodies can completely block the trachea and cause atelectasis of the lung on that side.
[0003] In the critical care medicine department, many patients often have respiratory tract obstructions such as sputum or blood clots, and need to use airway clearance devices to clear the airway. However, in the existing technology, most airway clearance devices can only decompose airway obstructions through decomposition fluids, and when decomposing debris on the inner wall of the airway, they can only be decomposed through other devices. This not only adds trouble to the patient's airway clearance, but also affects the use effect of the airway clearance device. Utility Model Content
[0004] The utility model aims to provide an airway clearing device for critical care respiratory support to solve the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an airway clearing device for respiratory support in critical care medicine, comprising an airway clearing device body and an adjustment component; wherein the airway clearing device body comprises a accommodating rubber kit and an airway clearing tube; the airway clearing tube is fixed on the accommodating rubber kit; the adjustment component is arranged on the airway clearing tube; wherein the adjustment component comprises an annular groove, an adjustment kit, an annular part and a water hole; an annular groove is provided on the airway clearing tube; the adjustment kit is sleeved on the airway clearing tube; the annular part is sleeved in the annular groove, and the annular part is fixedly connected to one end of the adjustment kit; a number of water holes are evenly provided on the airway clearing tube and the adjustment kit.
[0006] As a preferred embodiment, the annular member is rotationally matched with the annular groove.
[0007] As a preferred embodiment, the water holes on the rod of the adjustment kit and the water holes on the rod of the airway clearing tube are arranged alternately, and the water holes on the head of the adjustment kit and the water holes on the head of the airway clearing tube are in the same position.
[0008] As a preferred embodiment, it further comprises a limiting assembly; the limiting assembly is arranged on the annular member.
[0009] As a preferred embodiment, the limit assembly includes a spring groove, a limit ball, a return spring and a limit groove; the annular member is provided with a plurality of spring grooves on the side close to the accommodating rubber sleeve; the limit ball is slidably arranged in the spring groove; the two ends of the return spring are respectively fixedly connected to the spring groove and the limit ball; the annular groove is provided with a plurality of limit grooves on the side close to the spring groove.
[0010] As a preferred implementation, the limiting ball is snap-fitted into the limiting groove.
[0011] As a preferred embodiment, more than half of the volume of the limiting ball is located in the spring groove.
[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:
[0013] The airway clearing device for critical care respiratory support, through the provided adjustment component, when it is necessary to use the airway clearing device body to decompose the patient's airway obstruction, first, rotate the adjustment kit to make the adjustment kit rotate on the airway clearing tube, and make the annular part rotate in the annular groove, until the water holes on the head of the adjustment kit and the water holes on the head of the airway clearing tube are in the same position, thus completing the adjustment of the airway clearing device body. When it is necessary to use the airway clearing device body to decompose the debris on the inner wall of the patient's airway, rotate the adjustment kit to make the water holes on the rod of the adjustment kit and the water holes on the rod of the airway clearing tube be in the same position. The two different functions are realized by the airway clearing device body, thereby greatly improving the use effect of the airway clearing device body.
[0014] The airway clearing device for critical care respiratory support is provided with a spring groove, a limiting ball, a rebound spring and a limiting groove. When the annular part rotates in the annular groove, the spherical surface of the limiting ball will squeeze the inner wall of the limiting groove, causing the limiting ball to slide in the spring groove, causing the rebound spring to be forced to contract until the spherical surface of the limiting ball contacts the inner wall of the annular groove. At this time, the rebound spring no longer contracts. When the spherical surface of the limiting ball contacts the inner wall of the next limiting groove, the rebound spring is no longer stressed and begins to stretch, causing the limiting ball to slide in the opposite direction in the spring groove until the limiting ball is engaged with the next limiting groove. Through the matching relationship between the limiting ball and the limiting groove, not only can the rotation of the annular part in the annular groove be restricted, but it can also be used to prompt the position of the water hole on the adjustment kit and the water hole on the airway clearing tube, so as to facilitate the overlap or stagger of the position of the water hole on the adjustment kit and the water hole on the airway clearing tube.

[0030] The utility model provides an adjustment component 2. When it is necessary to use the airway clearing device body 1 to decompose the patient's airway obstruction, first, rotate the adjustment kit 202 to make the adjustment kit 202 rotate on the airway clearing tube 102, and make the annular member 203 rotate in the annular groove 201, until the water hole 204 on the head of the adjustment kit 202 is in the same position as the water hole 204 on the head of the airway clearing tube 102, and the adjustment of the airway clearing device body 1 is completed. When it is necessary to use the airway clearing device body 1 to decompose the debris on the inner wall of the patient's airway, rotate the adjustment kit 202 to make the water hole 204 on the rod of the adjustment kit 202 be in the same position as the water hole 204 on the rod of the airway clearing tube 102, and realize two different functions through the airway clearing device body 1, thereby greatly improving the use effect of the airway clearing device body 1.
[0031] As a preferred embodiment, it also includes a limit assembly 3; the limit assembly 3 is arranged on the annular member 203; wherein, the limit assembly 3 includes a spring groove 301, a limit ball 302, a return spring 303 and a limit groove 304; the annular member 203 is provided with six spring grooves 301 on the side close to the accommodating rubber kit 101; the limit ball 302 is slidably arranged in the spring groove 301; wherein, more than half of the volume of the limit ball 302 is located in the spring groove 301; the two ends of the return spring 303 are fixedly connected to the spring groove 301 and the limit ball 302 respectively; twelve limit grooves 304 are provided on the side of the annular groove 201 close to the spring groove 301; wherein, the limit ball 302 is snap-fitted with the limit groove 304.
[0032] The utility model provides the spring groove 301, the limiting ball 302, the return spring 303 and the limiting groove 304. When the annular member 203 rotates in the annular groove 201, the spherical surface of the limiting ball 302 will squeeze the inner wall of the limiting groove 304, so that the limiting ball 302 slides in the spring groove 301, and the return spring 303 is forced to shrink until the spherical surface of the limiting ball 302 contacts the inner wall of the annular groove 201.

[0033] How it works
[0034] When the airway clearing device for critical care respiratory support of the present invention needs to be used to decompose the airway obstruction of the patient, first, the adjusting kit 202 is rotated to make the adjusting kit 202 rotate on the airway clearing tube 102, so that the annular member 203 rotates in the annular groove 201, so that the spherical surface of the limiting ball 302 presses the inner wall of the limiting groove 304, so that the limiting ball 302 slides in the spring groove 301, and the return spring 303 is forced to shrink until the spherical surface of the limiting ball 302 contacts the inner wall of the annular groove 201. At this time, the return spring 303 no longer shrinks. When the spherical surface of the limiting ball 302 contacts the inner wall of the next limiting groove 304, the return spring 303 is no longer stressed and begins to stretch, so that the limiting ball 302 slides in the spring groove 301 in the opposite direction until the limiting ball 302 is engaged with the next limiting groove 304. When the water hole 204 on the head of the adjustment kit 202 is in the same position as the water hole 204 on the head of the airway clearing tube 102, the adjustment of the airway clearing device body 1 is completed.
