JPS5835261Y2 - Holding device for anesthesia and oxygen inhalation masks - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a flexible tube holding device for an anesthesia and oxygen inhalation mask.

Generally, a mask for anesthesia or oxygen inhalation is fixed via an adapter such as a chimney piece to the tip of each flexible tube connected to an exhalation valve and an inhalation valve, respectively.

Conventionally, during surgery, measures have been taken to hold this mask in the hand and lightly press it against the patient's face, or to hold the mask by attaching the flexible tube to a frame such as a bed. In the former case, the worker had to endure the fatigue of holding a mask for a long time, and at the same time was forced to perform other tasks with at least one hand.

Moreover, in the latter case, it is necessary to attach a flexible tube every time the surgery is performed, and at the same time, the stability is poor, and the situation may endanger the patient, so it is not a safe method of use.

The present invention has been devised to eliminate such drawbacks, and one embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of an anesthesia mask supported using the holding device according to the present invention. In the figure, 1 is a closed circulation general anesthesia machine, for example, and this anesthesia machine 1 is attached to the side of the device The provided cylinder 3 and the anesthetic gas and oxygen flowing out from the cylinder 3 are approximately 5k
A pressure reducing valve 4 that reduces the pressure to g/cm2, a flow control valve 5, a flow meter 6, a vaporizer 7 that vaporizes a volatile anesthetic, and a surface vaporizer that obtains a desired concentration of frosene gas. Canister (carbon dioxide absorption device) with flowtick 8 and breathing bag 9 connected at the bottom
10, and an exhalation valve 1 for making the respiratory air flow in one direction.
1 and an inhalation valve 12, exhalation and inhalation flexible pipes 13 and 14 connected to each of these valves 11 and 12, and an anesthesia mask 15 on one side and an anesthetic mask 15, respectively. It is composed of connected chimney pieces 16.

17 is a holding device for an anesthesia mask, which is the core of this invention.
This device 17 is made by bending a flat metal plate into an L-shape by press working, as shown in the gap in FIGS. It is L-shaped, which has a placing part 19 and an upright part 20 which is formed by vertically standing the bent side surface of this placing part 19. It is arranged so that it can be fixed naturally and removably by the weight of the futon 21 and pillow 22 and the weight of patient A's head.

Further, on the flat upper half-periphery side edge of the upright portion 20, there are symmetrically formed serpentine pipe hooking recesses 23 to 25 in which the exhalation and inhalation serpentine pipes 13 and 14 are removably engaged. Three steps are formed from the periphery toward the center at predetermined intervals in the direction.

The proximal end of each of these recesses 23 to 25 is connected to the flexible pipe 13.
, 14 are formed in an arc shape along the outer periphery, and the opening is slightly wider than the base end so that the flexible tubes 13 and 14 can be smoothly attached and detached.

Furthermore, in this embodiment, a pair of left and right recesses 26,26.
．． 28.28 are formed in three stages in the vertical direction, and the distance between these recesses, that is, the interval between 26.27 and 27.28 is the distance between the recesses on the upright portion 20 side, which is 23.
This is set narrower than the interval between 24 questions and 24.25.

In other words, each of the recesses 23 to 25 on the side of the standing part 20 is used for a large-diameter flexible tube for adults, and each of the recesses 2 on the side of the mounting part 19 is
6 to 28 are small-diameter flexible tubes designed for use by children.

Then, the flexible tubes 13, 14 are inserted into any one of these recesses 23 to 28 that is optimal according to the patient A's physique, etc., and the narrow diameter portions of the flexible tubes 13, 14 are inserted into the recess. The anesthetic mask 15 is held by being hooked onto the inner circumferential edge via the flexible tubes 13 and 14.

Although the holding device 17 is manufactured in a single process by pressing a metal flat plate, it is also possible to make the holding device 17 by molding it from a synthetic resin material instead of metal because it will be lightweight.

In this way, in the present invention, the placing part 13 and the standing part 20 are formed by bending a flat thin plate of a predetermined width into an L shape, and the peripheral edges of the placing part 19 and the standing part 20 are Concave pipe hooking recesses 23 of appropriate depth from the peripheral edge toward the center at predetermined intervals in the side direction.
28, and the flexible pipe hooking recesses 23 to 2 of the upright portion 20.
5 is a large-diameter flexible tube for adults, and the flexible tube hooking recesses 26 to 26 of the mounting portion 19 are provided. 28 is formed with a small-diameter flexible tube for children, and this device can be easily maintained in a stable state by inserting the placement part 19 between the bed and the futon. Of course, it can be fixed to the recess 23 which is cut out from the peripheral edge toward the center.
~25, the flexible pipes 13 and 14 can be easily attached and detached,
Moreover, since the placing part 19 and the standing part 20 are formed from flat thin plates, the large diameter parts of the flexible tubes 13 and 14 are positioned so as to sandwich the peripheral part of the recess from both the front and back sides, and the small diameter parts are placed in the recess. By hooking, the flexible tubes 13 and 14 are reliably prevented from moving in the longitudinal direction, thus eliminating the need to constantly manually hold the mask 15 in close contact with the patient's face, and stably fixing and supporting the mask 15 in an accurate position. It is possible.

In addition, in the present invention, similar to the upright part 20, the placing part 19 is provided with recesses 26 to 28 for hanging small-diameter baby pipes, so that the upright part 20 can be held horizontally and the bed and futon can be connected to each other. By inserting the tube between the two, the concave tube hooking recesses 26 to 28 of the placing portion 19 can be converted into a small diameter tube and used for a child patient.
