Description

A kind of trachea foreign body forceps caliper
Present patent application is the divisional application of following patent application
Title：A kind of trachea foreign body forceps and caliper
Application number：201410379921.3
The applying date：2014-08-04.
Technical field
The invention belongs to medical instruments field, and in particular to foreign body in airpassage wrench structure.
Background technology
Foreign matter can be hindered breathing after suction respiratory tract by mistake, can cause asphyxia even dead when serious, after aspirated foreign body It must take out in time.Usual foreign body is to coordinate trachea foreign body forceps to be operated using airway wall, the foreign body forcepses of prior art All it is metal material, is repeatedly used after cleaning and sterilizing, but the chela position of foreign body forcepses is generally hinge with caliper main body Form connection is connect, link position has dead angle, it is difficult to thoroughly clean up, infection risk, using effect be present during reuse It is undesirable.And if the disposable cost of the foreign body forcepses of metal material is too high and waste of resource.
The content of the invention
The technical problems to be solved by the invention are：In view of the deficienciess of the prior art, offer is a kind of simple in construction, make With easy to operate, gripping foreign matter is reliable, and cost is low, trachea foreign body forceps caliper that can be disposable.
To realize the purpose of the present invention, it is achieved using following technical scheme：
A kind of trachea foreign body forceps caliper, described caliper is by flexible rubber or integrally moulded, the caliper By the pipe joint b of tubular, the support ring of tubular, the clamping jaw joint face of spheric and three clamping jaws successively one in structure Body connects and composes；The external diameter of the support ring is more than pipe joint b external diameter, and described clamping jaw joint face is outwardly, three folders Pawl is uniformly connected on the outer surface of clamping jaw joint face and three clamping jaws are on a circumference, the inner surface shaping of the clamping jaw There is clip tooth；The embedded pipe of a hard is embedded with described pipe joint b and support ring jointly, is embedded with described clamping jaw The reinforcing panel of hard；An annular rib, annular rib and three folders are formed in the middle part of the inner surface of the clamping jaw joint face Circle diameter residing for pawl is equal, the 1/2-2/3 of a diameter of support ring internal diameter of the annular rib；The clamping jaw joint face of caliper It is recessed under the suction function of pipe joint b sides to support ring, so as to drive three clamping jaws to be drawn close to clamping jaw joint face center In contraction state.
Described caliper is by elastic caoutchouc or integrally moulded, and easy to process, production cost is low, surface Glabrous thorn Or pointed end, to sense of discomfort caused by tracheae and damage small；The clamping jaw joint face is driven by negative pressure and produces Inward deflection So as to drive three clamping jaws to do pinching action to clamp foreign matter；Described reinforcing panel and embedded pipe make caliper have enough machines Tool intensity and clamping jaw joint face position and can have good elasticity, ensure that clamping jaw can effectively and firmly clamp foreign matter.Institute Each clamping jaw is consistent action when the annular rib stated enables the clamping jaw joint face be produced indent deformation by negative pressure, avoids pressing from both sides Pawl action is unstable and foreign matter is produced movement again.The 1/2-2/3 of a diameter of support ring internal diameter of the annular rib, so press from both sides Pawl joint face has good elasticity in the radial direction, and coordinate with annular rib has enough mechanical strengths again, ensures folder Pawl action is strong.
