Problems solved by technology

[0002] Multiple serous cavity effusions and pneumothorax are common diseases in major hospitals. Thoracic cavity, abdominal cavity, pericardial cavity and other punctures are also commonly performed in major hospitals. The etiological diagnosis of patients provides necessary help, but the puncture needles used in major hospitals are still unsatisfactory, because the existing puncture needles have no scale mark or the scale mark is not clear, and there is no fixing device, so when performing puncture, the operator It is not easy to grasp the depth of the puncture, and the puncture needle is easy to slide back and forth without being noticed by the operator, especially when the gas in the pleural cavity and the effusion of the chest, abdomen, and pericardium are small, it is easy to damage normal tissues, which brings potential risks to the puncture ; The length of the existing puncture needle is single, and for the effusion in the deeper part, especially the encased effusion, it is often difficult for the conventional puncture needle to reach the position of the effusion, which cannot meet the requirements of clinical medical personnel

Embodiment Construction

[0013] The structure of the present invention is as figure 1 -2 shows: a positioning puncture needle with a scale display, including a needle head 1, the needle head 1 is connected to the needle seat 2, the needle seat 2 is provided with a branch pipe 4, and the branch pipe 4 is provided with a one-way valve 5. 1 is provided with a plurality of main scale marks 6 and auxiliary scale marks 7, a positioning nut 3 is set on the needle 1, and a needle length mark 8 is also provided on the needle base 2.

[0014] In the present invention, the auxiliary scale marks 7 are located adjacent to each other. Usually, the distance between two adjacent main scale marks 6 is 1 cm; the auxiliary scale marks 7 are equidistantly distributed between the two main scale marks 6 .

[0015] The main scale mark 6 and the auxiliary scale mark 7 of the present invention are obtained by using the industrial treatment principle of turning the surface of steel parts blue and black. The mark on the needle...

Abstract

The invention discloses a location puncture needle with scale display. The puncture needle comprises a needle head, wherein the needle head is connected to a needle base; a branch tube is arranged on the needle base; a check valve is arranged in the branch tube; a plurality of main scale marks and auxiliary scale marks are arranged on the needle head; and a locating screw cap sleeves the needle head. A needle head length mark is additionally arranged on the needle base. A fixed device is arranged on the puncture needle of the invention and the fixed device is moved to the corresponding position of a body surface after successful puncture and is fixed, so that medical personnel can master a punctured depth easily during operating, and the operator can feel more assured since the puncture needle is prevented from sliding forth and back; in addition, the puncture needle can relieve complications caused by human factors in the puncture, improve the success rate of the puncture, reduce medical risks, reduce medical disputes and relieve pain in patients.

Description

technical field [0001] The invention relates to a puncture needle, in particular to a puncture needle with a scale and a fixing device, which can be widely used in puncture operations by medical staff in hospitals. Background technique [0002] Multiple serous cavity effusions and pneumothorax are common diseases in major hospitals. Thoracic cavity, abdominal cavity, pericardial cavity and other punctures are also commonly performed in major hospitals. The etiological diagnosis of patients provides necessary help, but the puncture needles used in major hospitals are still unsatisfactory, because the existing puncture needles have no scale mark or the scale mark is not clear, and there is no fixing device, so when performing puncture, the operator It is not easy to grasp the depth of the puncture, and the puncture needle is easy to slide back and forth without being noticed by the operator, especially when the gas in the pleural cavity and the effusion of the chest, abdomen, ...
