Abstract
The invention provides a medical plastic water-stopping clamp. The clamp comprises an open-ended water-stopping clamp body. A clamp block is arranged on the open-ended water-stopping clamp body. The inside of the water-stopping clamp body on the other side of an opening is provided with a clamp table matching the clamp block and a limiting block. A gap for holding the clamp block is formed between the clamp table and the limiting block. The position, close to one side of the clamp block, of the water-stopping clamp body is provided with a water-stopping protrusion. The other side of the water-stopping clamp body is provided with a water-stopping table. The left and right sides on the water-stopping table are provided with guide pipe channels. When water is stopped, the clamp block is downwardly pressed and crosses the clamp table to drop into a gap formed between the clamp table and the limiting block. The limiting block stops the clamp block from further downwardly pressing. Stress damage of a liquid pipe is avoided due to excessive exertion.
Description
Technical field
The present invention relates to a kind of tongs, particularly relate to a kind of medical plastic tongs.
Background technology
Medical plastic tongs is a kind of working of plastics for sealing being usually used in infusion pipeline.Medical plastic tongs one
As include the tongs body of an opening, one end, opening two ends is provided with fixture block, and the other end is provided with chuck；Tongs body
It is respectively provided on two sides with sealing fin；Sealing fin is respectively provided on two sides with catheter channel.Catheter channel passes for liquid pipe；
Fixture block coordinates with chuck and is used for closing tongs；Sealing fin for stuck liquid pipe when tongs closes, plays sealing and makees
With.Tongs sealing is convenient to operation, but when sealing, owing to sealing fin and liquid pipe contact area are little, and
Fixture block be stuck in chuck after due to effect of inertia unavoidably can further clamping, cause the most excessive and then be easily damaged liquid pipe；
The most when the temperature is low, liquid pipe toughness is poor, it is easier to block bad liquid pipe, causes liquid tube lifetime low.
Summary of the invention
The present invention solves that above technical problem provides a kind of medical plastic tongs.
The technical solution used in the present invention is: a kind of medical plastic tongs, including the tongs body of an opening, opens
The described tongs body of mouth side is provided with fixture block, is provided with described inside the described tongs body of opening opposite side
The chuck of fixture block cooperation and limited block；The gap only holding described fixture block is formed between described chuck and described limited block；Described
Tongs body is provided with sealing projection near described fixture block side, and opposite side is correspondingly provided with sealing platform；Left at described sealing platform
It is respectively equipped with catheter channel on the tongs body of right both sides.When sealing, fixture block, fixture block is pressed down to fall after crossing chuck
In gap between chuck and limited block, limited block prevents pressing down of fixture block, it is to avoid overexertion causes liquid pipe
After stuck, stress is damaged further.
Infringement to liquid pipe during in order to alleviate sealing further, described sealing projection is along liquid pipe bearing of trend cross section arcuately.
Arch increases contact area between sealing projection and liquid pipe, and liquid pipe pressure is had good transitional function, it is to avoid
Stress is concentrated, and therefore further mitigates liquid pipe institute undermined.
As preferably, described sealing platform is along liquid pipe bearing of trend rectangular in cross-section.
As preferably, described sealing projection is perpendicular to cross section, described liquid pipe direction arcuately.
As preferably, it is indent circular arc that described sealing platform is perpendicular to cross section, described liquid pipe direction top margin.
Be perpendicular on liquid pipe direction, sealing projection be outer convex, sealing platform be indent arc, matching form closes, and makes
Obtain during sealing the most reliable to liquid pipe pressure.
The present invention has the advantage that with good effect: owing to the present invention uses as above technical scheme, when sealing, press down
Fixture block, fixture block falls after crossing chuck in the gap between chuck and limited block, limited block prevent fixture block further under
Pressure, it is to avoid overexertion causes the after death stress damage further of liquid pipe clamp.
Except the technical characteristic that present invention solves the technical problem that, constitute technical scheme described above and by these skills
Outside the advantage that the technical characteristic of art scheme is brought, other technologies problem that the present invention can solve, technical scheme are wrapped
The advantage that the other technologies feature contained and these technical characteristics are brought, makees the most in detail hereinafter in conjunction with accompanying drawing
Explanation.

Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing
Describe in detail as follows:
As it is shown in figure 1, the present embodiment is a kind of medical plastic tongs, including the tongs body 1 of an opening, opening one
The described tongs body 1 of side is provided with fixture block 4, is provided with described inside the described tongs body 1 of opening opposite side
The chuck 5 of fixture block 4 cooperation and limited block 7；Form, between described chuck 5 and described limited block 7, the seam only holding described fixture block 4
Gap 6；Being provided with sealing projection 2 at described tongs body 1 near described fixture block 4 side, opposite side is correspondingly provided with sealing platform
3；The tongs body 1 of described sealing platform 3 left and right sides is respectively equipped with catheter channel.
As in figure 2 it is shown, described sealing projection 2 is along liquid pipe 8 bearing of trend cross section arcuately；Described sealing platform 3 is along liquid pipe 8
Bearing of trend rectangular in cross-section.
As it is shown on figure 3, described sealing projection 2 is perpendicular to cross section, described liquid pipe 8 direction arcuately；Described sealing platform 3 hangs down
Directly in cross section, described liquid pipe 8 direction top margin be indent circular arc.
It is to say, sealing projection 2 work surface is sphere, sealing platform 3 work surface is that face of cylinder liquid pipe is from sealing projection 2
Sphere and sealing platform 3 the face of cylinder between pass；When sealing, fixture block 4 is stuck between chuck 5 and limited block 7；?
Be perpendicular in liquid pipe 8 plane, sealing platform 3 with sealing projection 2 in the arc coordinated, by the most stuck for liquid pipe 8；Flat
Row is in the plane of liquid pipe 8 bearing of trend, and liquid pipe 8 passes through the transition of sealing projection 2 sphere, is gradually stuck, then by
Gradually being released, it is to avoid stress concentration, the liquid pipe 8 alleviated damages.
In the present embodiment, sealing projection may be used without cylinder, and corresponding sealing platform uses plane, is parallel to liquid Guan Yan
Stretch direction structure schematic diagram identical with Fig. 2, transitional function can also be played when sealing.
Above embodiments of the invention are described in detail, but described content has been only presently preferred embodiments of the present invention, no
The practical range for limiting the present invention can be considered.All impartial changes made according to the present patent application scope and improvement etc.,
Within all should still belonging to the patent covering scope of the present invention.
