Abstract
The utility model discloses the cylinder of a kind of retainer plate of safety type thoracic cavity pin, including inner hollow, the bottom of the cylinder opens up a semicircular indentations upwards；One raised buckle is set in the outside wall surface of the cylinder, and the raised buckle is located at the surface of the semicircular indentations, and the axis of the raised buckle and the angle of a lateral edges of the semicircular indentations are 30~40 °.The retainer plate of safety type thoracic cavity of the present utility model pin, for connecting needle tubing and folding sheath, the convenient folding sheath after the completion of the pin use of thoracic cavity forms effective protection to tip portion.
Description
Technical field
It the utility model is related to technical field of medical instruments, and in particular to a kind of retainer plate of safety type thoracic cavity pin.
Background technology
Pneumothorax puncture needle is mainly used in following field：
(1) to the judgement of Pleural Effusion；
(2) the lung pressure symptom caused by a large amount of hydrops or pneumatosis is alleviated；
(3) fester treatment pyothorax is drained；
(4) avoid pleaural adhesion from thickening, influence PFT；
(5) injection of medicine into thoracic cavity.
Existing pneumothorax puncture needle product, the protection to needle point is not taken, in actual use because thoracic cavity is worn
The relatively thick cutting edge simultaneously of pricker needle tubing is than sharp situation, it is easy to scratch or stab after the completion of use medical personnel and
Medical waste treatment people, certain risk be present.
Utility model content
The purpose of this utility model is the defects of overcoming prior art, there is provided a kind of retainer plate of safety type thoracic cavity pin, is used
In connection needle tubing and folding sheath, the convenient folding sheath after the completion of the pin use of thoracic cavity forms effective protection to tip portion.
Realizing the technical scheme of above-mentioned purpose is：A kind of retainer plate of safety type thoracic cavity pin, include the cylinder of inner hollow
Body, the bottom of the cylinder open up a semicircular indentations upwards；One raised buckle is set in the outside wall surface of the cylinder, should
Raised buckle is located at the surface of the semicircular indentations, and the axis of the raised buckle and the one of the semicircular indentations
The angle of lateral edges is 30~40 °.
A kind of retainer plate of above-mentioned safety type thoracic cavity pin, wherein, the depth of the semicircular indentations is 2mm.
The retainer plate of safety type thoracic cavity of the present utility model pin, it is convenient in thoracic cavity pin for connecting needle tubing and folding sheath
Folding sheath forms effective protection to tip portion after the completion of use, it is possible to prevente effectively from needle point is exposed to medical personnel or phase
The personnel that pass is likely to contact needle point damage.
Brief description of the drawings
Fig. 1 is the three-dimensional structure diagram of the retainer plate of safety type thoracic cavity of the present utility model pin；
Fig. 2 is the top view of the retainer plate of safety type thoracic cavity of the present utility model pin；
Fig. 3 is the front view of the retainer plate of safety type thoracic cavity of the present utility model pin.
Embodiment
In order that those skilled in the art are better understood when the technical solution of the utility model, with reference to attached
Its embodiment is described in detail figure：
Refer to Fig. 1 to Fig. 3, most preferred embodiment of the present utility model, a kind of retainer plate of safety type thoracic cavity pin, including it is interior
The hollow cylinder 31 in portion, the bottom of cylinder 31 open up a semicircular indentations 32 upwards, and the depth h of semicircular indentations 32 is
2mm；One raised buckle 33 is set in the outside wall surface of cylinder 31, the raised buckle 33 is located at the surface of semicircular indentations 32,
And the axis of raised buckle 33 and the angle α 2 of a lateral edges of semicircular indentations 32 are 30~40 ° of
The retainer plate of safety type thoracic cavity of the present utility model pin, in use, retainer plate is rotatably socketed in true tube top portion
Retainer plate buckle on, and the transverse part of needle tubing is located in semicircular indentations 32.So, retainer plate can be done around retainer plate buckle
0~180 ° of rotation.Folding sheath is rotatably connected on raised buckle 33, and folding sheath is promoted after the completion of the pin use of thoracic cavity,
So that retainer plate is rotated, when a lateral edges of the semicircular indentations 32 of retainer plate are in contact with the transverse part of needle tubing, press
The needle tubing protector of pressure folding sheath is folded it, while needle tubing is fixed by the needle tubing card valve in needle tubing protector.
The retainer plate of safety type thoracic cavity of the present utility model pin, it is convenient in thoracic cavity pin for connecting needle tubing and folding sheath
Folding sheath forms effective protection to tip portion after the completion of use, it is possible to prevente effectively from needle point is exposed to medical personnel or phase
The personnel that pass is likely to contact needle point damage.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
Type, and be not used as to restriction of the present utility model, as long as in spirit of the present utility model, to described above
Change, the modification of embodiment will all fall in Claims scope of the present utility model.
