Abstract

A compact venous needle and blood collection puncture needle guiding apparatus that eliminates human error during puncture and can perform appropriate puncture regardless of the skill of the person performing the puncture and the state of the patient or the like. An upper arm fixing portion, a probe, and a display monitor are provided. The probe and the display monitor are integrally configured, and the probe captures a cross-sectional image in a major axis direction that is a blood vessel axis direction. And a second imaging unit that captures a cross-sectional image in the minor axis direction perpendicular to the major axis direction, and the display monitor 3 simultaneously or simultaneously with the first imaging unit and the second imaging unit. By using a compact intravenous injection and blood collection puncture needle guiding device characterized in that the probe 2 is slidably held on the upper arm fixing portion 1, the skill of the person performing the puncture, the patient, etc. Appropriate puncture can be performed regardless of the state.

Description

The present invention relates to a device that assists a nurse or the like in guiding a puncture target into a blood vessel so that a venous injection or an arterial injection can be performed safely and accurately.

Currently, venipuncture and arterial puncture performed by nurses in outpatients and blood collection rooms are performed based on many years of experience in the field and technical guidance from seniors. However, puncture techniques are difficult for children and elderly patients with thin blood vessels and fat and fat patients, and the blood vessel wall may be damaged due to a needle puncture, etc. There were also concerns.

JP-A-11-33026

In order to eliminate the human error at the time of puncture as described above, it is desired that appropriate puncture can be performed regardless of the skill of the person performing the puncture and the state of the patient or the like.

In order to solve the above problems, the present invention includes an upper arm fixing portion, a probe, and a display monitor, wherein the probe and the display monitor are integrally formed, and the probe is a cross section in a major axis direction that is a blood vessel axis direction. A first image capturing unit that captures an image, and a second image capturing unit that captures a cross-sectional image in a short axis direction perpendicular to the major axis direction. The display monitor includes a first image capturing unit and a second image capturing unit. A compact venous needle guidance and puncture needle guiding device is provided in which the imaging unit is displayed at the same time or in a switched manner, and the probe is slidably held on the upper arm fixing unit.

According to the compact intravenous injection and blood collection puncture needle guidance device of the present invention, it can be performed while monitoring the puncture action that relied on the nurse's skill and intuition, reducing the burden on the subject, The needle can be punctured without human error without requiring a high level of skill.

It is the schematic of the puncture needle guidance device for compact type intravenous injection and voting of the present invention. It is a schematic diagram of the probe of the compact type intravenous injection and puncture needle guidance device of the present invention. It is the screen of the display monitor of the puncture needle guidance device for compact type intravenous injection and voting of the present invention.

Examples of the compact type intravenous injection and puncture needle guidance device of the present invention are shown below.

FIG. 1 is a schematic view of a compact intravenous injection and puncture needle guiding apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes an upper arm fixing portion, which has a shape in which a part of an annular bracelet is opened. It has the function to do. Reference numeral 2 denotes a probe which is slidably supported by the upper arm fixing portion 1. Since it is a slide type, it can be securely attached and fixed to the arm of each subject. A display monitor 3 is fixed to the probe 2 and can display an image captured by the probe 2 on a screen.

FIG. 2 is a schematic diagram of the probe 2, which has a T-shape and is a long-axis linear probe 2 a that takes a shallow cross-sectional image in the long-axis direction that is the blood vessel axis direction, and is orthogonal to the long-axis direction. It comprises a short-axis linear probe 2b that takes a shallow cross-sectional image in the short-axis direction. The long axis linear probe 2a confirms the position in the width direction of the blood vessel, and the short axis linear probe 2b confirms the position in the depth direction of the blood vessel. Further, a puncture position fixing marker may be attached to the center of the probe 2 to serve as a guide for the injection needle.

FIG. 3 is a diagram showing a screen of the display monitor 3, and displays an image captured by the probe 2 shown in FIG. FIG. 3A shows a state in which an image in the long axis direction of a blood vessel imaged by the long axis linear probe 2a is displayed. FIG. 3B shows a state in which an image in the short axis direction of the blood vessel imaged by the short axis linear probe 2b is displayed. The images in FIGS. 3A and 3B are switched and displayed on the entire screen, but two screens in the major axis direction and the minor axis direction may be simultaneously displayed in one screen. Good.

As described above, the compact intravenous injection and puncture needle guidance device of the present invention is a portable portable device that integrates the probe, display monitor, and upper arm fixing part, so it can be taken outside the hospital and used anywhere can do.
