Abstract
The utility model relates to the technical field of medical instruments and particularly relates to a bubble-extraction-type intravenous injector. The bubble-extraction-type intravenous injector consists of an injection needle, a sleeve, a ring cavity, a clamp nut, a conduit, a main syringe, an auxiliary syringe, a rubber cover, an air collection hopper, an air discharge tube and a connection tube, wherein the sleeve is sleeved at the tail end of the injection needle and adhered with the injection needle into a whole; the injection needle is integrated with the air discharge tube and is orthometric and communicated with the air discharge tube; the air discharge tube is connected with the bottom end of the air collection hopper by virtue of the connection tube; and the syringe needle of the auxiliary syringe penetrates through the rubber cover and is positioned in the air collection hopper. According to the utility model, the injection needle is arranged to be in a tee-joint structure, and the auxiliary syringe is used for extracting residual bubbles, so that the bubbles can be effectively prevented from entering into blood vessels in an injection process, and the safety of injection with a remaining needle is improved.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of bubble extraction-type intravenous injector.
Background technology
Application number is the Jugular vein imbedding type injector of 200810157693.X, and its purpose is to utilize easily remaining needle that the patient is carried out the cervical region intravenous injection, has avoided puncture repeatedly that the jugular vein blood vessel is caused damage.But its conduit is being inserted in the telescopic process; Be very easy to make in the extraneous air admission sleeve pipe; Thereby generation bubble; Bubble can block blood capillary with blood flow, and the blood supply of local organization is produced influence difficult to the appraisal, does not stop outside air and in conduit and tube process, produces and have practicable method in this patent application.
The utility model content
This utility model provides a kind of and can the bubble that produce in conduit and the tube process be eliminated clean bubble extraction-type intravenous injector before intravasation for solving the deficiency of prior art.
The scheme that solves this utility model technical problem is: bubble extraction-type intravenous injector is made up 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 processed of elastomeric material be placed in the tail end of entry needle and bonding with entry needle be an integral body.Entry needle is in part and exhaustor in the sleeve pipe to be whole and the two quadrature and to communicate with each other, and exhaustor stretches out from telescopic sidewall, and is connected with the bottom of gas collection bucket through connection tube.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.
Telescopic tail end is a truncated cone-shaped; The outer wall of said truncated cone-shaped is threaded; The truncated cone-shaped that clamp nut is placed in telescopic tail end partly goes up and cooperatively interacts with the screw thread of sleeve pipe tail end; Inwall at telescopic tail end has an annular chamber, and the upper end of conduit is enclosed within on the tail end of entry needle and is in the said annular chamber, and the lower end of conduit is connected with main syringe.
During operation, in the time need the tail end of the upper end of conduit and entry needle being connected, the upper end with conduit is inserted in the said annular chamber earlier, and the rotation clamp nut, and under the extruding of clamp nut to telescopic truncated cone-shaped tail end, the upper end of conduit is fixed in the 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 through secondary syringe.
Adopt such scheme, compared with prior art, the utlity model has following marked improvement:
1. be set to three-port structure owing to this utility model entry needle, and used secondary syringe that residual bubble is extracted, can stop bubble intravasation in the injection process effectively, increased through remaining needle and carried out injection safety.
2. because this utility model adopts soft connection tube that exhaustor is connected with the gas collection bucket, can reach no matter which direction entry needle is in can both guarantee that the gas collection bucket is in the effect of vertical state, for the extraction of bubble provides convenience.
3. telescopic tail end is a truncated cone-shaped and the cooperating of clamp nut; Make conduit can make things convenient for, be firmly fixed in the sleeve pipe, avoided in the prior art, conduit and telescopic joint not compact; Situation about coming off easily takes place; Simultaneously, also avoided, thereby ambient atmos is from the lasting situation generation that produces bubble of the joint entering injection of the two owing to conduit and telescopic joint not compact.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is done further to describe.
Bubble extraction-type intravenous injector is made up 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 processed of elastomeric material be placed in entry needle 1 tail end and bonding with entry needle 1 be an integral body.Entry needle 1 is in part and exhaustor 10 in the sleeve pipe 2 to be whole and the two quadrature and to communicate with each other, and exhaustor 10 stretches out from the sidewall of sleeve pipe 2, and is connected with the bottom of gas collection bucket 9 through 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 the gas collection bucket 9.
The tail end of sleeve pipe 2 is a truncated cone-shaped; The outer wall of said 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, and the upper end of conduit 5 is enclosed within on the tail end of entry needle 1 and is in the said annular chamber 3, and the lower end of conduit 5 is connected with main syringe 6.
During operation; In the time need the tail end of the upper end of conduit 5 and entry needle 1 being connected, the upper end with conduit 5 is inserted in the said annular chamber 3 earlier, 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 the annular chamber 3.The bubble that the joint produces can enter into gas collection bucket 9 through connection tubes 11 from exhaustor 10, and can extract bubble this moment through secondary syringe 7.
