Description
Technical field
What the present invention proposed is the disposable central venous catheter insertion device that medical instruments field is used for human body therapy and monitoring.
Background technology
Before the present invention proposed, the structural texture that is used for the disposable central venous catheter embedded device of human body at medical instruments field was: cavity one side having the angle syringe needle and having a syringe of Y shape interface is provided with wire leading pipe.In use, penetrate in the human vein blood vessel through human body breast skin of neck, when in finding syringe, having blood to flow out through the angle syringe needle of manpower with syringe; Explain that syringe needle has penetrated in the vein blood vessel, at this moment, wire guide is inserted in the vein blood vessel through Y shape needle tubing; Then central venous catheter is inserted in the vein blood vessel along seal wire, extracts seal wire out, retain conduit; Input liquid reaches to vein blood vessel blood transfusion, transfusion through conduit, and the purpose of measuring central venous pressure.
The shortcoming that existing central venous catheter is inserted the device existence is:
1, syringe needle is an angle, is opened on puncture needle foremost, when angle partly penetrates into blood vessel wall generation blood vessel wall and rides, though pumpback also has blood to flow out, can occur that seal wire is inserted difficulty and seal wire is put the blood vessel outside, makes operation failure.
2, after piercing needle penetrates blood vessel, at first insert seal wire, be that the center penetrates conduit more then with the seal wire, complex steps has increased the stimulation to blood vessel.
3, Y shape sting device and seal wire manufacture difficulty are big, and cost is high, and yield rate is low.
Summary of the invention
Insert the existing shortcoming of device to existing central venous catheter, the present invention proposes disposable central venous catheter and insert device.The puncture needle pin hole horizontally set of this device avoids blood vessel to ride; The skin-dilating needle of being furnished with the semicircle section solves the skin reaming and helps the technical problem that conduit inserts; Be connected with puncture shank connecting portion through guide pin, solve conduit in company with the technical problem of inserting.
The scheme that technical solution problem of the present invention is adopted is:
Broken handle is taken over syringe and is connected, and inside has passage, in the end of broken handle barrier film is housed, and stretches in the puncture needle boom end puncture shank inner chamber in the broken handle and is provided with puncture shank connecting portion, and the front end of puncture shank is a piercing needle; Skin-dilating needle is the semicircle tubulose of taper, and front end is provided with the skin-dilating needle head, and the rear end is provided with the skin-dilating needle handle; Be installed with guide pin in the conduit, the guide pin front end is provided with the guide pin connecting portion, and the guide pin rear portion is provided with the guide pin handle; Piercing needle is inclined plane shape or taper, and sidepiece is provided with horizontal pin hole.
Good effect, the vascular puncture that the present invention and tradition are used is inserted the device of conduit and is compared, and has simple in structurely, easy to use, reduces damage, simplifies step, safe and reliable and the low advantage of cost, suitable medical apparatus and instruments as the human body diseases diagnosis and treatment is used.

Among the figure, 1. syringe is taken over, the broken handle of 1.1., 1.2. barrier film, 1.3. puncture shank connecting portion; 1.4. the puncture shank, 1.5. piercing needle, 1.6. pin hole, 2. skin-dilating needle, 2.1. skin-dilating needle head; 2.2. the skin-dilating needle handle, 3. conduit, 4. guide pin, 4.1. guide pin connecting portion, 4.2. guide pin handle.
The specific embodiment
According to shown in Figure 1: broken handle 1.1 is taken over 1 with syringe and is connected; Inside has passage; In the end of broken handle barrier film 1.2 is housed, stretches into that intracavity is provided with puncture shank connecting portion 1.3 in puncture shank 1.4 ends in the broken handle, the front end of the shank that punctures is a piercing needle 1.5.
According to shown in Figure 2: skin-dilating needle 4 is provided with skin-dilating needle head 4.1 for the semicircle tubulose of taper, front end, and the rear end is provided with skin-dilating needle handle 4.2.
According to shown in Figure 3: be installed with guide pin 4 in the conduit 3, the guide pin front end is provided with guide pin connecting portion 4.1, and the guide pin rear portion is provided with guide pin handle 4.2.
According to shown in Figure 4: piercing needle 1.5 is an inclined plane shape, and the inclined-plane blocks, and sidepiece is provided with horizontal pin hole 1.6.
According to shown in Figure 5: piercing needle 1.5 is a taper, and the awl end is the state of blocking, and taper piercing needle both sides are respectively equipped with horizontal pin hole 1.6.
Above-mentioned each parts make up use step by step.
Use of the present invention:
The syringe adapter of puncture needle is joined with syringe, firmly piercing needle is inserted in the specific vein blood vessel of breast neck, when blood flows out through skin; Skin-dilating needle is inserted in the skin along puncture shank periphery, and rotation, make the other skin histology of puncture shank lax; Help inserting conduit, take off skin-dilating needle then, pass barrier film with the guide pin that is with conduit; Through guide pin connecting portion and the continued access of puncture needle connecting portion, guide pin and puncture shank are become one, reuse is defeated broken broken handle; The conduit that guide pin is peripheral inserts in blood vessel along the puncture shank, when reaching assigned address, extracts guide pin and puncture shank; Conduit is deposited in the vein blood vessel, in blood vessel, injects liquid, realize transfusion and gaging purpose through conduit.
Advantage:
1, use of the present invention can avoid bevel needle to ride blood vessel wall, makes seal wire slip into difficulty and seal wire and slides into blood vessel and cause puncture failure outward, has improved the success rate of puncture.
2, puncture needle syringe needle of the present invention is oblique or taper, and sidepiece has horizontal pin hole, makes puncture needle skid off blood vessel because of slight outwards moving after the success that prevents to puncture.
3, after puncturing successfully, the puncture needle shank is connected lengthening with guide pin through connecting portion, forms the puncture shank and makes up with guide pin, and have the function of complete seal wire, and be convenient to conduit and penetrate, and has alleviated the stimulation to blood vessel, has simplified operating procedure.
4, puncture needle shank of the present invention can be processed thinner diameter, can alleviate the pair damage that puncture causes, in case the mistake perforating arteries, the hemostasis of compressing blood vessel is easier, reduces the incidence rate of hematoma.
