Abstract
The utility model provides a deep vein puncture device, including syringe needle, puncture cylinder, piston, handle, its characterized in that: the position of the corresponding inclined plane of the pintle orientation of syringe needle is provided with guide structure, guide structure is red long square bulge, puncture cylinder the inside is provided with the pressure measurement device, the pressure measurement device comprises space, piston, stamen silk and the pressure sensor of the piston front end of puncture in the cylinder jointly, the stamen silk sets up in puncture cylinder ware, pressure sensor sets up on the piston. Carrying out dark vein when puncture through this scheme, medical personnel not only can pass through guide structure, and accurate messenger's seal wire is walked according to the circuit of wanting, sets up the scale in addition on the syringe needle, the degree of depth that the grasp of being convenient for was thrust. Through the pressure measurement device on the puncture cylinder, according to the pressure value, whether the judgement of preparing more avoids the mistake to sting the artery for dark vein simultaneously.
Description
Technical field
This utility model relates to a kind of technical field of medical instruments, is specifically related to a kind of deep vein puncture device.
Background technology
In medical practice, deep vein puncture technology is an important diagnostic techniques, is usually used in vein and should not puncture and need long-term infusion or need to rapidly input the situation of liquid nutritional.Existing piercing needle is made up of needle point, pin stalk and pintle, needle point is typically provided with inclined-plane, need seal wire is sent into Deep venou when puncturing, this will derivation silk trend according to anticipation circuit walk, but at present needle point towards having uncertainty, often operation is gone in the memory by medical personnel, it is possible that the situation of seal wire deviation anticipation route；Although and existing deep vein puncture solves the problem of puncture and intubation, but how to prevent accidental injury large artery trunks, it is to avoid the unstability aspect in piercing process is the most unsatisfactory.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is proposed that a kind of simple in construction and have the deep vein puncture device of guide frame and pressure tester.
For realizing the purpose of this utility model, the utility model proposes a kind of deep vein puncture device, including syringe needle, piercing needle cartridge, piston, handle, it is characterised in that: the pintle inclined surface of described syringe needle towards position be provided with guide frame, described guide frame is that red rectangle is protruding；Be provided with pressure tester inside described piercing needle cartridge, described pressure tester be the space by the piston nose in piercing needle cartridge, piston,StamenSilk and pressure transducer collectively constitute, describedStamenSilk is arranged in piercing needle cartridge device, and described pressure transducer is arranged on piston.
It is provided with scale, it is simple to grasp pin further and obstruct the degree of depth thrust on syringe needle described further.
Described furtherStamenSilk is made up of shape-memory material such as Nitinol.
Described furtherStamenSilk surface configuration has insulating coating, the corrosion to it of the anti-Hemostatic Oral Liquid.
The beneficial effects of the utility model are: this programme design is ingenious, by this programme when carrying out deep vein puncture, medical personnel, not only by guide frame, make seal wire walk according to the circuit wanted accurately, and scale is set on syringe needle, it is simple to grasp the degree of depth thrust.Simultaneously by the pressure tester on piercing needle cartridge, according to force value, more prepare determines whether Deep venou, it is to avoid thorn tremulous pulse by mistake, the program has significant practicality, it is easy to be acceptable to the market popularization.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further:
Fig. 1 is structural representation of the present utility model.
1. piercing needle cartridge 2. syringe needle 3. pressure transducer 4.StamenSilk 5. piston 6. handle 7. guide frames.
Detailed description of the invention
It is structural representation of the present utility model referring to Fig. 1, the utility model proposes a kind of deep vein puncture device, including syringe needle 2, piercing needle cartridge 1, piston 5, handle 6, it is characterized in that: the pintle inclined surface of described syringe needle 2 towards position be provided with guide frame 7, described guide frame 7 is that red rectangle is protruding；Be provided with pressure tester inside described piercing needle cartridge 1, described pressure tester be by the space of piston 5 front end in piercing needle cartridge 1, piston 5,StamenSilk 4 and pressure transducer 3 collectively constitute, describedStamenSilk 4 is arranged in piercing needle cartridge 1, and described pressure transducer 3 is arranged on piston 5.
During use, first syringe needle 2 is penetrated skin, then take out pressure piercing needle cartridge 1, determine whether Deep venou according to the force value of pressure transducer 3, if Deep venou, according to guide frame 7, stamen silk 4 is thrust skin according to needle point direction, then carry out next step operation.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model, and the technology contents of the most detailed description of this utility model is known technology.
