Description

A kind of terminal device for radial artery puncturing

Technical field

The utility model relates to a kind of fixed devices of puncture, and in particular to a kind of terminal device for radial artery puncturing, Belong to medical auxiliary apparatus technical field.

Background technique

Radial artery puncturing art is a kind of technology being commonly used in clinical position, can be used for monitoring arterial pressure, and intervention is controlled It treats and takes a blood sample etc..It usually requires to make hand abduction in puncture process, column shape is rolled into towel is operated on, by patient's Wrist is placed on column and operates on towel, and palm palmar is fixed in hand cradle with adhesive tape, could sufficiently expose in this way wrist portion in favor of It is more easily operated, therefore before carrying out puncture procedure arm position is supported and is fixed and is particularly important.

Existing radial artery puncturing art needs patient's palmar surfaces of fingers carrying on the back song as far as possible, makes site of puncture skin-tightening and radial artery It is fixed；The impression radial artery pulse to be punctured is removed with finger fingertip again, to reduce the area that operator experiences beating as far as possible, contracting Small puncture range, is easily found optimum puncturing point in this way.In the operation of prior art radial artery puncturing, it is located at radial artery puncture point The highest point of horizontal plane, it is particularly important.But this needs patient sufficiently to cooperate patient, keeps upper limb position required by patient.It is existing Upper limb position needed for though technology helps patient to keep using some auxiliary devices, because of the pain stimulation in puncturing, or because of patient Itself joint condition, involuntary upper limks movements, the case where leading to puncture failure is also more generation.

Utility model content

Technical problem to be solved in the utility model is, the shortcomings that for the above prior art, proposes a kind of for oar The terminal device of arteriopuncture, it is compact-sized reasonable, radial artery puncturing success rate is improved, the comfort level of patient is combined.

In order to solve the above-mentioned technical problem, the utility model provides a kind of terminal device for radial artery puncturing, including Bottom plate, palm restraint strap and the cushion block being mounted on hand cradle plate are fixed with the cushion block in the middle part of the plate upper surface, The cushion block includes the pedestal being connected with bottom plate, flexible lifting cushion and tail end check valve, and the flexible lifting cushion is mounted on On the pedestal, there is cavity in the flexible lifting cushion, the cavity is equipped with the charge and discharge port communicated with the outside world, described The tail end check valve is installed, the tail end check valve is connected with external gas source at charge and discharge port；Pass through the tail end check valve Into cavity, inflation/deflation realizes that the control flexible lifting cushion is gone up and down；It is equipped at the bottom plate of the side of the cushion block solid Determine the palm restraint strap of hand, palm restraint strap both ends are fixed on the back side of hand cradle plate by fixing piece.

The utility model further limits technical solution, is previously described for the terminal device of radial artery puncturing, the palm The fixing piece of restraint strap is velcro, hasp or bandage；The flexible lifting cushion upper surface is equipped with matched with human arm Radian.

It is previously described for the terminal device of radial artery puncturing, the tail end check valve includes spool, reset spring and valve Shell, the spool are made of closure gasket and the guide post being arranged on closure gasket, and the valve casing is by mouthpiece and package structure Be less than package diameter at, the mouthpiece diameter, one end of the mouthpiece is connected with one end of package, the package it is another Spring stand is equipped at the port at end, the spool is mounted in valve casing, and the guide post of the spool is plugged in mouthpiece, valve The closure gasket of core is sealed on one end that mouthpiece is connected with package, and described reset spring one end resists closure gasket, another End is connected with the spring stand on package.

Further, it is previously described for the terminal device of radial artery puncturing, the upper surface of the bottom plate is pasted equipped with the back of the hand Indicating area is closed, to prompt patient's hand placement position.

Beneficial effect is: the terminal device for radial artery puncturing of the utility model, will when carrying out radial artery puncturing Patient hand is fixed on bottom plate, forces wrist flex by liftable cushion block, so that site of puncture skin-tightening, radial artery Closer to body surface, facilitates puncture, improve the success rate of disposable puncture；Liftable cushion block is set in wrist portion, can be used to adjust Wrist flex degree is saved, different patients wrist's bendings is adapted to, improves patient comfort；The inflatable flexible lifting cushion of wrist The height that can be gone up and down by how much controls of gas injection rate, demand when adapting to puncture, flexibility lifting cushion reduce to patient's skin The compressing of skin, semicircular palm restraint strap can be adjusted according to the size of patient's palm, both saved trouble, is time saving, is safe, can It leans on, and improves patient comfort；The tail end check valve used in the application, is designed using special construction, can not only be guaranteed It smoothly inflates, while being also highly resistant to the lower pressure in patient's puncture process, it is ensured that flexibility lifting cushion does not lose heart And deformation, guarantee that is punctured is normally carried out with stable posture.
