Description
Technical field
The invention belongs to technical field of medical instrument, and in particular to a kind of self-destructing type transfusion syringe.
Background technique
Intravenous infusion needle is one of the most frequently used, simplest medical instrument, infusion apparatus include sequentially be fixedly connected it is defeated
Liquid needle, attachment base and perfusion tube, attachment base are equipped with the connection wing, and facilitating medical staff to pinch the connection wing makes transfusion needle prick people to skin
In skin.With advances in technology, transfusion needle by original multiple disinfection, reuse mode, develop to current disposable
The mode used.But existing disposable infusion needle does not have self-destroying function, slightly processing can be reused, once it repeats
It uses, the cross-infection of the blood diseases such as AIDS, hepatopathy or other diseases is just easily caused, to cause greatly to endanger to society
Evil, furthermore the unshielded measure of syringe needle after use, it is exposed outside, can also handle to Biohazard Waste make troubles, and syringe needle can also
It punctures skin and causes cross-infection.
In view of the above problems, Chinese Patent Application No. discloses for CN201520496439.8, " one kind is easy to use certainly
Ruin formula transfusion needle ", which slides by being provided with annular groove on syringe needle and is provided with elastic spacing fixture block and limit on sheath
Position protrusion, after the completion of infusion, retention bead clamps annular groove under the action of elastic spacing fixture block, so that syringe needle can not
It moves forward and backward, but the patent is only to be fixed on transfusion needle in sliding sheath, the structure of transfusion needle is completely, to pass through
Transfusion needle can be taken out by cutting off sliding sheath, slightly handled and be just able to carry out secondary use self-destructed purpose is not achieved.
Summary of the invention
The invention is intended to provide a kind of self-destructing type transfusion syringe, the structure of transfusion needle can be destroyed.
In order to achieve the above objectives, the present invention provides following technical scheme：A kind of self-destructing type transfusion syringe, including transfusion needle, also
Including first sleeve, elevating mechanism and the second sleeve for being socketed in first sleeve periphery, the transfusion needle is arranged in first sleeve
Interior, the syringe needle of the transfusion needle reaches outside second sleeve；Lateral through slot has been set gradually from left to right in the second sleeve
And link slot, the right side of the transverse direction through slot are connected to link slot, the connection wing is slidably connected at lateral lead to after passing through first sleeve
In slot and link slot, the transverse direction through slot includes the second lateral through slot and the first lateral through slot being arranged from outside to inside；Described
Interlayer is equipped in the barrel of two sleeves, the elevating mechanism is set to the side in interlayer and close to transfusion needle syringe needle, the lifting
The bottom of mechanism is equipped with sponge block and the cement reservoir equipped with glue, and cement reservoir is located at the right side of sponge block, the first sleeve
Outer wall is equipped with the supporting block for being used to support elevating mechanism, and the length of the described first lateral through slot is greater than the length of supporting block, described
Perfusion tube is fixedly connected with first sleeve.
The working principle of the invention：
The syringe needle of transfusion needle is located at outside second sleeve, by pinch connection the wing can penetrate in patient skin carry out it is defeated
Liquid.
The left side that the wing is located at the first lateral through slot is connected, supporting block can support elevating mechanism, after completing infusion, pass through
The connection wing is pulled towards right side, perfusion tube is fixedly connected with first sleeve, and the connection wing drives transfusion needle synchronous mobile towards right side,
Transfusion needle enters in second sleeve, because the length of the first lateral through slot is greater than the length of supporting block, when the connection wing is moved to
After in link slot, supporting block is not just supporting elevating mechanism, and elevating mechanism decline drives sponge and cement reservoir to move down, stores up
Capsule and sponge, which drop to, is in same level with syringe needle.The wing is connected by rotation, the connection wing is rotated and moved in link slot
It moves into the second lateral through slot, supporting block and elevating mechanism dislocation, is pushing the connection wing to the direction of cement reservoir, the connection wing drives
Transfusion needle is punctured in cement reservoir and is ultimately inserted into sponge towards movement outside second sleeve, transfusion needle, stops the mobile connection wing,
Glue enters in transfusion needle and is covered on infusion wire surface, and after glue dries, transfusion needle is blocked and is adhered on sponge.
Beneficial effects of the present invention：The wing is connected by pulling, after the connection wing is pierced into cement reservoir, cement reservoir rupture, glue
Entering in liquid storage needle and adhere to the surface of transfusion needle after glue dries, just makes transfusion needle after transfusion needle is inserted into sponge
It blocks and is adhered on sponge, just reached self-destructed purpose after transfusion needle blocking, in addition residual liquid (blood in transfusion needle
Liquid, medical fluid) it will not leak out, transfusion needle is fixed in sponge, is not exposed to outside, such medical staff will not be stained with these
Liquid, while also avoiding being stabbed by transfusion needle, reduce infected probability.
Further, the elevating mechanism includes transverse bar and vertical bar, and the top of the vertical bar and transverse bar, which are fixed, to be connected
It connects, the vertical bar includes the first vertical bar, the second vertical bar and third vertical bar being set gradually from left to right, the sponge
The bottom of block, cement reservoir and the first vertical bar is fixedly connected, and the bottom of second vertical bar and third vertical bar passes through second
It is supported after sleeve with supporting block.The bottom and supporting block of second vertical bar and third vertical bar support, and just can pass through transverse direction in this way
Bar makes sponge block and cement reservoir be in hanging state, and after first sleeve is mobile towards right side, supporting block is moved a certain distance
Afterwards, the second vertical bar and third vertical bar are after the support of no supporting block, cement reservoir and sponge block decline.
Further, the right side of the second sleeve is clamped by the right side of buckle and first sleeve.The is realized by buckle
The connection of one sleeve and second sleeve.
Further, the thickness of the sponge block is greater than the length of the second lateral through slot.When the connection wing is in the second horizontal concrete chute
When mobile towards left side, setting in this way, the distance that limitation transfusion needle is moved to the left penetrate the syringe needle of transfusion needle will not
Sponge block.
Further, the slot diameter of the described second lateral through slot is gradually reduced from right to left.Setting in this way, the connection wing exist
When second lateral through slot moves from right to left, it can be connected in the second lateral through slot, reinforce the fixation to infusion apparatus.
Further, the direction of the thickness of the supporting block towards perfusion tube is gradually increased.When supporting block moves right, in this way
Setting can be such that the second vertical bar and third vertical bar is gradually reduced.
