Abstract
The invention relates to the technical field of medical appliance, in particular to a vacuum exhaust type jugular vein injector. The vacuum exhaust type jugular vein injector consists of an injection needle, a sleeve, an annular cavity, a tightening nut, a guide tube, a main syringe, an accessory syringe, a rubber cover, an air collection bucket, an exhaust tube and connecting tube, wherein the sleeve is sleeved on the tail end of the injection needle and is integrally spliced with the injection needle, the injection needle and the exhaust tube are an integer, are orthogonal and are communicated with each other, the exhaust tube is connected with the bottom end of the air collection bucket through the connecting tube, and a syringe needle of the accessory syringe penetrates through the rubber cover and is located in the air collection bucket. According to the vacuum exhaust type jugular vein injector, the injection needle is designed into a three-way structure, and residual air bubbles are extracted by using the accessory syringe, so that the air bubbles can be effectively prevented from entering blood vessels in an injection process, and the safety in injection through a detaining needle is improved.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of vacuum exhaust type jugular vein injector.
Background technology
Application number is the Jugular vein imbedding type injector of 200810157693.X, and its purpose is to utilize easily remaining needle to carry out the Jugular vessel injection to the patient, has avoided puncture repeatedly to jugular vein blood vessel injury.But in its conduit is inserted the process of sleeve pipe, be very easy to make extraneous air to enter in sleeve pipe, thereby generation bubble, bubble can block blood capillary with blood flow, the blood supply of local organization is produced impact difficult to the appraisal, do not stop outside air and produce in conduit and sleeve pipe cohesive process and have practicable method in this patent application.
Summary of the invention
The present invention provides a kind of and the bubble that produces in conduit and sleeve pipe cohesive process can be eliminated clean vacuum exhaust type jugular vein injector before intravasation for solving the deficiencies in the prior art.
The scheme that solves the technology of the present invention problem is: vacuum exhaust type jugular vein injector is made of entry needle, sleeve pipe, annular chamber, clamp nut, conduit, main syringe, secondary syringe, serum cap, gas collection bucket, exhaustor and connection tube.Wherein the sleeve pipe made of elastomeric material be placed in the tail end of entry needle and bonding with entry needle be an integral body.It is a whole and quadrature and communicating with each other both that entry needle is in part and exhaustor in sleeve pipe, and exhaustor stretches out from the sidewall of sleeve pipe, and is connected by the bottom of connection tube with the gas collection bucket.Connection tube is transparent flexible pipe.The gas collection bucket is up big and down small truncated cone-shaped cylindrical shell, and the upper end of gas collection bucket is by a discoidal serum cap sealing, and the syringe needle of secondary syringe passes serum cap and is in the gas collection bucket.
The tail end of sleeve pipe is truncated cone-shaped, the outer wall of described truncated cone-shaped is threaded, the truncated cone-shaped that clamp nut is placed in the tail end of sleeve pipe partly goes up and cooperatively interacts with the screw thread of sleeve pipe tail end, inwall at the tail end of sleeve pipe has an annular chamber, the upper end of conduit is enclosed within on the tail end of entry needle and is in described annular chamber, and the lower end of conduit is connected with main syringe.
During operation, when need to be connected in the upper end of conduit the tail end connection with entry needle the time, first the upper end with conduit is inserted in described annular chamber, and the rotation clamp nut, and under the extruding of clamp nut to the truncated cone-shaped tail end of sleeve pipe, the upper end of conduit is fixed in annular chamber.The bubble that the joint produces can enter into the gas collection bucket through connection tube from exhaustor, and can extract bubble this moment by secondary syringe.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. because the present invention's entry needle is set to three-port structure, and use secondary syringe that residual bubble is extracted, can effectively stop bubble intravasation in injection process, increased the safety of injecting by remaining needle.
2. because the present invention adopts soft connection tube, exhaustor is connected with the gas collection bucket, can reach no matter which direction entry needle is in can guarantee that the gas collection bucket is in the effect of vertical state, for the extraction of bubble provides convenience.
3. the tail end of sleeve pipe is truncated cone-shaped and the coordinating of clamp nut, make conduit can facilitate, be firmly fixed in sleeve pipe, avoided in prior art, conduit and telescopic joint not compact, holding caducous situation occurs, simultaneously, also avoided due to conduit and telescopic joint not compact, thereby ambient atmos enters the situation generation of the lasting generation of injection bubble from joint both.

In figure: 1. entry needle 2. sleeve pipe 3. annular chamber 4. clamp nut 5. secondary syringe 8. serum cap 9. gas collection bucket 10. exhaustor 11. connection tubes of the main syringe 7. of conduit 6.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Vacuum exhaust type jugular vein injector is made of entry needle 1, sleeve pipe 2, annular chamber 3, clamp nut 4, conduit 5, main syringe 6, secondary syringe 7, serum cap 8, gas collection bucket 9, exhaustor 10 and connection tube 11.Wherein the sleeve pipe 2 made of elastomeric material be placed in the tail end of entry needle 1 and bonding with entry needle 1 be an integral body.It is a whole and quadrature and communicating with each other both that entry needle 1 is in part and exhaustor 10 in sleeve pipe 2, and exhaustor 10 stretches out from the sidewall of sleeve pipe 2, and is connected with the bottom of gas collection bucket 9 by connection tube 11.Connection tube 11 is transparent flexible pipes.Gas collection bucket 9 is up big and down small truncated cone-shaped cylindrical shells, and the upper end of gas collection bucket 9 is by discoidal serum cap 8 sealings, and the syringe needle of secondary syringe 7 passes serum cap 8 and is in gas collection bucket 9.
The tail end of sleeve pipe 2 is truncated cone-shaped, the outer wall of described truncated cone-shaped is threaded, the truncated cone-shaped that clamp nut 4 is placed in the tail end of sleeve pipe 2 partly goes up and cooperatively interacts with the screw thread of sleeve pipe 2 tail ends, inwall at the tail end of sleeve pipe 2 has an annular chamber 3, the upper end of conduit 5 is enclosed within on the tail end of entry needle 1 and is in described annular chamber 3, and the lower end of conduit 5 is connected with main syringe 6.
During operation, when the tail end that need to be connected with entry needle in the upper end of conduit 5 connected, first the upper end with conduit 5 was inserted in described annular chamber 3, and rotation clamp nut 4, under the extruding of the truncated cone-shaped tail end of 4 pairs of sleeve pipes 2 of clamp nut, the upper end of conduit 5 is fixed in annular chamber 3.The bubble that the joint produces can enter into gas collection bucket 9 through connection tube 11 from exhaustor 10, and can extract bubble this moment by secondary syringe 7.
