Present patent application is the divisional application of following patent application
Title:Foreign body in airpassage clamp device and caliper
Application number:201410380315.3
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 which thoroughly cleaning is clean, there is infection risk, using effect 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 shortcomings of the prior art there is provided one kind is simple in construction, make
With easy to operate, gripping foreign matter reliability, low cost, the caliper structure of foreign body in airpassage clamp device that can be disposable.
To realize the purpose of the present invention, it is achieved using following technical scheme:
A kind of caliper structure of foreign body in airpassage clamp device, described caliper by flexible rubber or plastics one into
Type, the caliper in structure by the pipe joint b of tubular, the support ring of tubular, spheric rib joint face and four
Integrally connected is constituted individual holding piece successively;The external diameter of the support ring is more than pipe joint b external diameter, pipe joint b periphery shaping
There is anticreep convex tendon;Described rib connection is recessed towards support ring, and four holding pieces are uniformly adjacent to be connected to rib joint face
Outer surface periphery, the outer surface of holding piece and the outer surface smoother of support ring excessively connect, and the end of holding piece is tapered, four
The end of individual holding piece surrounds a circular open front, the 1/10-1/5 of a diameter of support ring external diameter of open front;Adjacent two
Latasuture is left between individual holding piece;Support rod is formed on the inside of each holding piece, the bottom of support rod is connected to
On the outer surface of the rib joint face, and the bottom of support rod extends to the center of rib joint face;Described pipe connects
Be embedded with jointly in head b and support ring be embedded with the embedded pipe of a hard, described support rod hard reinforcing it is embedding
Plate;Described pipe joint b inwalls slidably connect a piston body, and one is connected between piston body and the center of rib joint face
Individual connecting rod, the 1/10-1/5 of a diameter of support ring internal diameter of connecting rod;Uniformly through hole, through hole are offered on described rib joint face
The circumferentially array distribution centered on connecting rod;The piston body of caliper is moved under air pressure promotion to support ring direction, so as to pass through
Connecting rod drives rib joint face to bulge, and rib joint face drives support rod to be flared out driving holding piece together to open
Open;Unclamp rib joint face after flexible handle to reset under the effect of its own elastic force, support rod and holding piece are also reset to receipts
Contracting state.
Described caliper is easy to process by elastic caoutchouc or integrally moulded, and production cost is low, surface Glabrous thorn
Or pointed end, the sense of discomfort produced to tracheae and damage are small;The piston body is driven to holding piece direction by air pressure and moved,
So as to which rib connection is faced out into ejection, then rib joint face drives three support rod ends then to drive folder to external expansion
Hold piece expansion, piston body, rib joint face reset during air pressure is cancelled, so as to do pinching action different to wrap for holding piece
Thing;Described reinforcing panel and embedded pipe make caliper there is enough mechanical strengths and rib joint face position can have it is good
Elasticity, it is ensured that holding piece can effectively and firmly clamp foreign matter.On the one hand described through hole enables piston body both sides to produce
Pressure differential and beneficial to piston body movement, another aspect foreign matter stuck position a small amount of hydrops that may be present can from through hole suck rib
In space between joint face and piston body.The 1/10-1/5 of a diameter of support ring external diameter of the open front, so can be true
Protect holding piece easily to open, can guarantee that nipped foreign matter will not come off from open front again.A diameter of support ring of the connecting rod
The 1/10-1/5 of internal diameter, such connecting rod both can guarantee that to be connected firmly with rib joint face, while can ensure that rib joint face again
Deformation quantity is larger, holding piece is opened by a relatively large margin, the foreign matter larger beneficial to volume is clamped.The diameter of the annular rib
For the 1/2-2/3 of support ring internal diameter, such rib joint face has good elasticity in the radial direction, coordinates with annular rib
There is enough mechanical strengths again, it is ensured that holding piece action is strong.
