Description

Angle measuring puncture needle

Technical Field

The utility model relates to a arteriovenous puncture needle.

Background

Hemodialysis is the most common medical means in hospital medicine and is used for treating renal failure, acute pancreatitis, fulminant hepatitis, postoperative liver failure, and the like. Hemodialysis must be performed by puncturing the artery or vein of the patient with an arteriovenous puncture needle. During puncture, the puncture angle has high requirements, namely the puncture depth is different according to the blood vessel condition of a patient, the angle can be judged by visual inspection only by the experience of a nurse, the puncture difficulty is higher for a novice, and the success at one time is difficult, so the pain of the patient is increased, and the contradiction between doctors and patients is easily caused.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an angle measurement pjncture needle can real-time measurement puncture angle.

In order to solve the technical problem, the technical scheme of the utility model is to adopt an angle measurement puncture needle, which comprises a puncture needle body, wherein the rear end of the puncture needle body is provided with a needle seat and a needle wing which is fixed on the needle seat and is convenient to hold; the rear end of the needle seat is connected with the joint through an extension pipe; the needle base is provided with an angle measuring device for measuring angles.

As an improvement, the angle measuring device comprises a shell, wherein an annular channel is arranged in the shell; the channel is internally provided with a small ball which can roll along the channel; and the shell is provided with scale marks for marking angles. The small ball can roll along the channel under the driving of gravity, so that the position of the small ball is correspondingly changed when the angle of the puncture needle is changed, and the puncture angle is measured according to the position of the small ball.

As a further improvement, the radius of the circle in which the channel lies perpendicular to the needle body is indicated as 0 °, and the radius parallel to the needle body is indicated as 90 °. So that the indication corresponds to the actual puncture angle.

As a further improvement, the housing is provided with a channel that is partially transparent. The position of the small ball is convenient to observe.

As an improvement, the needle wing is arranged on the side surface of the needle seat, and the angle measuring device is arranged on the side, opposite to the position of the needle wing, of the needle seat. The handle is convenient to hold and observe.

The utility model discloses an useful part lies in: the puncture needle with the structure measures the puncture angle in real time by utilizing the position of the small ball staying under the driving of gravity, the measurement is accurate, the real-time display is realized, and the measurement device does not need to be adjusted. Has high practical value in clinic or teaching.

The labels in the figure are: 1 puncture needle body, 2 needle seats, 3 extension tubes, 5 shells, 6 channels, 7 balls and 8 human bodies.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.

As shown in fig. 1, the utility model comprises a puncture needle body 1, wherein a needle base 2 and a needle wing (not shown in the figure) fixed on the needle base 2 for holding are arranged at the rear end of the puncture needle body 1; the rear end of the needle seat 2 is connected with a joint through an extension tube 3; the needle base 2 is provided with an angle measuring device for measuring angles. Preferably, the needle wing 4 is arranged on the side surface of the needle seat 2, and the angle measuring device is arranged on the side of the needle seat 2 opposite to the position of the needle wing 4.

The angle measuring device comprises a shell 5, wherein an annular channel 6 is arranged in the shell 5; the housing 5 is transparent in the part provided with the channel 6. A small ball 7 capable of rolling along the channel 6 is arranged in the channel 6; and scale marks for marking angles are arranged on the shell 5. The radius of the circle in which the passage 6 is located perpendicular to the puncture needle body 1 is indicated as 0 °, and the radius parallel to the puncture needle body 1 is indicated as 90 °.

When in use, the nurse holds the needle wing 4 with the thumb and the index finger for puncturing. The human body 8 is placed in a horizontal position, and the plane of the channel 6 is vertical to the horizontal plane, so that the included angle a between the puncture needle body 1 and the human body 8 is consistent with the included angle b between the vertical line from the center of the small ball 7 to the human body and the scale mark 0. This corresponds to a change in the position of the ball 7, regardless of the change in the angle of the needle. The nurse can read the puncture angle directly through the scale line on the housing 5.

The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
