Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention belongs to the field of medical equipment for diagnosis, and more specifically, it is used for collecting body fluid etc. with a puncture needle while displaying an ultrasonic tomographic image. The present invention relates to an ultrasonic glove for use in puncturing.

[Technical background of the invention and its problems]

Traditionally, a suitable puncture cannula (hereinafter referred to as a puncture needle) has been used to remove body tissue or body fluids such as the liver or kidneys for diagnostic purposes. An ultrasonic puncture glove (hereinafter referred to as a probe) is used so that safer punctures can be performed while simultaneously checking the movement of the needle on the display. In this glove, as shown in FIG. 1, a large number of ultrasonic transducing elements 2 are arranged in parallel on the body contacting surface 1σ of the puncturing glove body iVc, which has a substantially rectangular parallelepiped shape.

Each of these ultrasonic transducer elements 2 is connected to a display VC (not shown) via a cable 6 attached to one side of the probe body 1. By sequentially driving each of the ultrasonic transducer elements 2, each ultrasonic wave A VC is provided so that a tomographic image of the organ j in contact with the conversion element 2 can be displayed on the display. A U-shaped slit 4 is opened in the center of the body contacting surface 1α of the glove body 1. The slit 4 opens upward from the slit 4 and reaches the opposite surface 5 of the body contacting surface 1α. A puncture hole 8 is constituted by a pair of inner surfaces 6.6 and its back surface 7.The inner surface 6 of this puncture hole 8VC is
．． A puncture needle (not shown) is placed between the holes 6 and 6 to perform puncturing.

A probe configured in this way may be contaminated due to bleeding from within the subject during puncture and blood in the puncture needle (cell fluid and blood adhering to the tip of the needle).
, there is a risk of complications such as serum hepatitis, etc., and it is essential to thoroughly disinfect each subject. However, in recent years, as the number of subjects to be punctured has increased, it has become impossible to puncture a large number of patients in a day by disinfecting gloves for each subject. Therefore, as a means to save the labor of sterilization, a method has been adopted in which a sterile bag (hereinafter referred to as a cover) is attached to the glove and the cover is replaced for each patient to prevent contamination of the sieve glove. FIG. 2 shows an example of an adapter for a central puncture type ultrasonic glove in which a cover is attached to the probe and the cover is semi-fixed to the puncture hole 8.

In FIG. 2, the gloves are given the same reference numerals as in FIG. 1, and the explanation thereof will be omitted. The cover 9 has a bag shape made of a flexible material such as polyethylene vinyl, and has a size sufficient to accommodate the glove body 1. The central puncture type ultrasonic glove adapter (hereinafter referred to as the adapter) 10 has a shape that matches the puncture hole 8 in the glove body 1VL, and has a trapezoidal surface 11 along the back surface 7 of the puncture hole 8 and the trapezoidal surface. 11 and adjacent to puncture hole 8
A side surface 12 that extends from the inner surface 6.6 and opens at a predetermined angle.
゜12. Further, a support piece 16 is provided at the narrow end of the adapter 10 so as to come into contact with the body contacting surface 1α of the glove when the adapter 10 is inserted into the puncture hole 8.

When the adapter 10 configured as described above is inserted into the puncture hole 8 of the probe housed in the cover 9 in the direction of arrow A in the figure, the back surface 7 and the inner surface 6 forming the puncture hole 8 are inserted.
．． 6 is a cover 9'fr: trapezoidal surface 1 of the adapter 10 through
1 and side 12.12VC covered, and adder 1
Since the support piece 13 of 0 contacts the body contacting surface 1α of the glove through the cover 9, it is prevented from being pulled out from above, and the cover 9 can be reliably compressed and held in the shape of the puncture hole 8. Therefore, since the puncture hole 8 and the body contacting surface 1a of the probe are completely covered by the cover 9, there is a risk of contamination due to adhesion of blood etc. during puncturing.
Moreover, since the adapter 10 has a shape that follows the puncture hole 8, puncturing can be performed in the same notch as the puncture hole 8 without any hindrance. However, when this adapter 10 is attached to and detached from all puncture holes 8, the support piece 16
There is a risk that the body contacting surface 1α may be damaged by pressing the body contacting surface 1α of the probe. This body contact surface 1
α is usually covered with an acoustic lens in order to converge the ultrasonic waves, and this acoustic lens generally has a t/c that makes the propagation within the lens the speed of sound and provides good density to the subject. Silicone rubber is used for this purpose. This silicone rubber has low abrasion resistance, so there is a very high risk of damage when attaching or detaching the adapter 100. Damage to the acoustic glass will have a negative effect on the transmission and reception of ultrasound waves, so it is important to ensure accurate diagnosis. has become an obstacle.

[Purpose of the invention]

The present invention has been developed in consideration of the circumstances described in Section 8e above, and is designed to prevent damage to the acoustic lens when attaching or removing the cover to the puncture hole, and to prevent the cover covering the puncture hole from bending or wrinkling.
