Description

Buccal type pulmonary alveolus surfactant injection catheter with laryngoscope assistance

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to buccal form alveolus surface active substance pours into pipe under laryngoscope is supplementary.

Background

The alveolar surfactant is a lipoprotein secreted by alveolar epithelial cells, is distributed on the surface of an alveolar liquid molecular layer, and has the function of reducing the surface tension of an alveolar liquid-air interface. The alveolar surfactant reduces the generation of interstitial fluid and interstitial fluid in alveoli, prevents pulmonary edema, reduces elastic resistance due to reduced surface tension, reduces inhalation resistance, and reduces inhalation work. The alveolar surfactant helps to maintain stability of the alveoli, and the density of the alveolar surfactant is increased as the radius of the alveoli is smaller and is also decreased as the radius is larger, so that the density of the surfactant is high and the effect of reducing surface tension is strong when the alveoli are small or exhale, and the alveolar surface tension is low, so that the alveoli can be prevented from collapsing; in the large alveolus or during inhalation, the density of the surfactant decreases and the surface tension of the alveolus increases, thus preventing the alveolus from over-expansion and maintaining the stability of the alveolus. Since part of the neonatal lung has not yet matured, especially premature infants, the absence of alveolar surfactant can cause diseases such as neonatal respiratory distress syndrome, etc., where exogenous input of alveolar surfactant is required. At present, the common technology of injecting lung surfactant through tubule (less innovative surfactant administration, LISA)/(minor innovative surfactant treatment, MIST) is the innovation of the technology of applying lung surfactant, the technology replaces trachea cannula with thin tube, completes the replacement therapy of exogenous lung surfactant by effective autonomous respiration of the infant patient, but the thin tube is soft, the hose is not easy to pass through when passing through narrow parts such as glottis and the like, the hose is not convenient to protect after being inserted, the conduit is possibly blocked due to the occlusion of the gum of the infant and the like, the prior art enters the alveolar surfactant through the autonomous respiration of the newborn, the alveolar surfactant is dripped into the trachea, the alveolar surfactant cannot be uniformly distributed on all alveolar surfaces through spontaneous respiration, and the liquid is directly injected into the tracheal cannula to easily cause choking.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the weak point among the prior art, provide one kind and conveniently insert the intubate, can be with the supplementary lower buccal form alveolar surfactant injection pipe of laryngoscope on alveolar surfactant evenly distributed alveolar surface.

In order to solve the technical problem, the utility model adopts the following technical scheme: the laryngoscope-assisted lower buccal alveolar surfactant injection catheter comprises a hose part and an oxygen hose, wherein the hose part is connected with the oxygen hose, one end part of the oxygen hose is connected with an active substance injection tube, the other end part of the oxygen hose is fixedly provided with a connecting tube, the end part of the connecting tube is fixedly provided with an outer circular plate, two hangers are fixed on the side part of the outer circular plate, the outer circular plate is connected with the connecting tube, the connecting tube is sleeved on the hose part, the inner side of the connecting tube is provided with an internal thread, the outer surface of the connecting tube is provided with an external thread, the internal thread of the connecting tube is in threaded connection with a tough hose part, the tough hose part is positioned on the outer side of the hose part, the connecting tube is also provided with a nipple part, the nipple part consists of a nipple and a mounting ring, the center of the mounting ring is fixedly provided with a threaded joint, the nipple is sleeved on the outer side of the tough hose part, and the mounting ring is mounted on the external thread on the outer surface of the connecting tube through the threaded joint; the outer wall of hose portion still is provided with length scale mark.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the new technology can control the flow rate of oxygen and the injection speed of the alveolar surfactant, further control the concentration of the alveolar surfactant entering the alveolus, blow away liquid through the oxygen, can be uniformly distributed after breathing, cannot cause choking cough, even blocks a trachea to cause asphyxia, and is safe and efficient. The novel technique conveniently passes the narrow position of glottis, and hose portion diameter is less moreover, and the texture softness reduces mucosa stimulation and damage to the trachea, can adopt the nipple to create the wound fixedly, and the convenient supplementary intubate of tough pipe portion can prevent to cause the hose obliteration to reasons such as gum interlock to the hose protection after the intubate.
