Abstract

The utility model discloses an arc scalp acupuncture, including syringe needle and butt joint pipe, connect syringe needle and transfer line respectively to the both ends of pipe, the syringe needle is the curved shape of arc, makes the flow of cerebrospinal fluid in the syringe needle more smooth and easy, and the syringe needle is difficult to deviate from in the pressure bag.

Description

Arc scalp needle

Technical Field

The utility model relates to a medical appliance, in particular to an arc scalp acupuncture.

Background

Scalp needle is not only used for clinical transfusion, but also used for external drainage of brain chamber, and is used for connecting brain chamber liquid storage bag and drainage device. When the cerebrospinal fluid needs to be continuously drained from the liquid storage bag to the outside of the body of a patient with a ventricular and abdominal shunt disorder or an Ommaya sac embedded infant, the scalp needle needs to be folded into 90 degrees and inserted into the liquid storage bag, the scalp needle is similar to a harbor needle of a transfusion harbor, and then the drainage device is connected with the tail end of the scalp needle to play a role in draining the cerebrospinal fluid.

The defects of the technology are as follows:

1. the syringe needle of traditional scalp needle is the shape of right angle bending, because contains matters such as fibrin, bacterium in the cerebrospinal fluid, can increase the viscosity of cerebrospinal fluid for the mobility of cerebrospinal fluid in the syringe needle weakens, and cerebrospinal fluid can flow unsmoothly in the corner of syringe needle, causes the jam even.

2. The needle is bent at right angles, namely the needle is in a gamma shape and comprises a gamma part and a gamma part, the end part of the gamma part is connected with the end part of the gamma part, the included angle between the gamma part and the gamma part is a right angle, after the needle penetrates into the pressure sac, only the gamma part vertically penetrates into the pressure sac, and the gamma part is exposed out of the scalp, so that the needle is easy to be separated from the pressure sac, and the infection risk is increased by repeated puncture.

3. After the needle is inserted into the pressure bag, the loosening of the "-" part may cause the corners of the needle to float due to the bent shape of the needle, resulting in unstable fixation of the "-" part which is attached to the scalp by application.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an arc scalp acupuncture, the syringe needle is the crooked shape of arc, makes the flow of cerebrospinal fluid in the syringe needle more smooth and easy, and the syringe needle is difficult to deviate from in the pressure bag.

In order to achieve the purpose of the invention, the utility model adopts the following technical scheme: an arc scalp needle comprises a needle head and a butt joint pipe, wherein the two ends of the butt joint pipe are respectively connected with the needle head and a transfusion pipe, and the needle head is in an arc-shaped bent shape.

Preferably, the needle head is provided with a first circular arc and a second circular arc, the two ends of the first circular arc are respectively connected with the end part of the butt joint pipe and the end part of the second circular arc, the first circular arc is bent from the butt joint pipe end towards one side of the butt joint pipe, the central angle corresponding to the first circular arc is between 10 degrees and 30 degrees, the second circular arc is reversely bent from the first circular arc end, and the central angle corresponding to the second circular arc is between 90 degrees and 120 degrees, so that the flow of cerebrospinal fluid in the needle head is smoother, and the needle head is not easy to be separated from the pressure bag.

Preferably, the outer circumferential surface of the butt joint pipe is provided with a needle wing, and the needle wing is convenient for holding the butt joint pipe.

Preferably, the needle wing is made of soft rubber, the soft rubber has elasticity, when the needle wing is pressed by fingers, the needle wing can deform, and the pressed position of the needle wing can be inwards concave, so that the butt joint pipe can be conveniently held.

Preferably, the needle wing is provided with a plurality of anti-slip pieces with different sizes, the anti-slip pieces are annular, the small anti-slip pieces are located in the rings of the large anti-slip pieces, and all the anti-slip pieces are concentrically arranged, so that the friction force between fingers and the needle wing is enhanced, the fingers are prevented from sliding on the needle wing, and the scalp needle is prevented from falling off from the hand.

Preferably, the anti-slip piece is positioned on the surface of the needle wing, which is back to the scalp, the surface of the needle wing, which faces the scalp, is a smooth surface, and the smooth surface of the needle wing is attached to the scalp, so that the contact position of the needle wing and the scalp is prevented from causing pressure damage.

Compared with the prior art, the arc scalp needle adopting the technical scheme has the following beneficial effects:

1. adopt the utility model discloses a curved scalp acupuncture, syringe needle are the crooked shape of arc, are the shape of right angle bending for the syringe needle, and the cerebrospinal fluid is more smooth and easy in the flow of the corner of syringe needle, avoids the corner of syringe needle to be blockked up.

2. After the needle penetrates the scalp, the path of the needle penetrating into the pressure bag is arc-shaped due to the fact that the needle is in the shape of arc-shaped bending, and compared with the way of vertically penetrating into the pressure bag, the needle is not easy to be separated from the pressure bag.

3. After the needle head punctures the scalp, the needle head is in the shape of arc bending, and the needle head is difficult to become flexible, so the butt joint pipe can be fixed on the scalp relatively stably through applying ointment or plaster.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The arc scalp acupuncture shown in fig. 1 to 2 includes a needle head 1 and a butt joint tube 2, two ends of the butt joint tube 2 are respectively connected with the needle head 1 and a transfusion tube 4, the needle head 1 is in an arc-shaped bent shape, the needle head 1 has a first arc 51 and a second arc 52, two ends of the first arc 51 are respectively connected with an end of the butt joint tube 2 and an end of the second arc 52, the first arc 51 is bent from the butt joint tube 2 end toward one side of the butt joint tube 2, a central angle corresponding to the first arc 51 is between 10 ° and 30 °, the second arc 52 is reversely bent from the first arc 51 end, and a central angle corresponding to the second arc 52 is between 90 ° and 120 °, so that cerebrospinal fluid flows more smoothly in the needle head 1, and the needle head 1 is not easy to escape from a pressure bag.
