Description

Specification

Pressure ulcer pocket measuring instrument

Technical field

[0001] The present invention relates to a pressure ulcer pocket measuring instrument for measuring the size of a pressure ulcer pocket.

Background art

[0002] Pressure sores are a type of pressure necrosis, and are ulcers that develop in areas where weight is applied due to impaired skin circulation when critically ill patients are bedridden for a long time. A pressure ulcer with a high degree of serious injury may have a pocket shape that opens on the surface of the skin.

Treatment of patients with pressure ulcer pockets requires regular measurement of the size of the pressure ulcer pocket, such as once a week. In the past, long cucumbers were inserted through the opening of the pressure ulcer pocket to find the contour of the pressure ulcer pocket, that is, the deepest part of the pocket, and the contour was marked to measure the size of the pressure ulcer pocket.

[0003] However, when long insulators are used, there is a risk of delaying healing of the wound by accidentally damaging the wound when the depth is difficult to understand. In addition, because the long eggplant is not flexible, there are cases where it cannot be measured depending on the patient's posture, and if the correct measurement cannot be performed, the wound may be contaminated.

[0004] Because of these problems, there is also an invention of a measuring instrument that uses a flexible material to prevent damage to pressure ulcer pockets (for example, Patent Document 1). However, even in a strong invention, there was a problem that grasping the outline of the pressure ulcer pocket had to rely on intuition, and skill was required.

Disclosure of the invention

[0006] The present invention has been made in view of the background as described above, and an object of the present invention is to provide a pressure ulcer pocket measuring instrument that can easily measure the size of a pressure ulcer pocket without damaging the wound. The subject is to provide. [0007] In order to solve the above-described problems, a pressure ulcer pocket measuring instrument according to the present invention includes a light emitting portion at a distal end to be inserted into a pressure ulcer pocket and a lead wire for supplying electricity or light to the light emitting portion. And a supply part connected to the insertion part and supplying electricity or light to the conducting wire.

This conducting wire is, for example, an electric wire or an optical fiber.

According to such a pressure ulcer pocket measuring instrument, it is possible to visualize the contour of the pressure ulcer pocket by inserting the insertion portion into the pressure ulcer pocket while causing the light emitting portion to emit light through the lead wire. Can be measured. In other words, since the pressure ulcer pocket contour is visually divided, it is possible to mark the contour without forcibly inserting a measuring instrument to the deepest part of the pressure ulcer pocket, and there is no risk of damaging the pressure ulcer pocket. Or the outline mark is accurate. Then, the outline of the pressure ulcer pocket can be visually observed and the area around the distal end of the insertion portion can be marked so that the work can be performed quickly.

[0008] It is preferable that the measuring instrument is covered with a flexible tube without damaging the pressure ulcer. By adopting such a flexible tube, the insertion part becomes flexible, and even when a measuring instrument is applied to the deepest part of the pressure ulcer pocket that is difficult to damage the wound, the wound is hardly damaged. In addition, if the insertion part is flexible, measurement can be easily performed regardless of the patient's posture.

[0009] In the measuring instrument, it is desirable that a scale is displayed on the tube. This makes it easier to measure the size of the pressure ulcer pocket.

[0010] The measuring instrument is provided with a fastener for applying an outer force clamping force of the tube.

It is desirable that the conducting wire and the tube are not displaced from each other. In this way, movement of the conducting wire and the light emitting portion relative to the tube can be prevented, and the tube and the conducting wire can be easily maintained in a certain shape, and the work of inserting the insertion portion into the pressure ulcer pocket can be easily performed.

[0011] In the measuring instrument, the conductive wire is preferably an electric wire. When we adopt electric wire

The light-emitting part can emit light sufficiently brightly even with a flexible thin line, and there is no risk of functional damage even when the insertion part is folded, so it is convenient for handling and carrying. [0012] In the measuring instrument, it is desirable to provide a disposable cover at the distal end of the insertion portion. By doing in this way, the infection by the bacteria between patients can be prevented.

[0013] In the measuring instrument, it is desirable that the light emitting unit emits red light. Since the human skin can easily pass red, if the light-emitting part emits light in red, it is easy to measure with little change in brightness before and after insertion into the pressure ulcer pocket.

[0014] As described above, according to the pressure ulcer pocket measuring instrument of the present invention, the size of the pressure ulcer pocket can be easily measured without damaging the wound.

Next, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the pressure ulcer pocket measuring instrument 1 is configured to include an insertion portion 10 formed in an elongated cord shape and a holding portion 20 including a supply portion connected to the proximal end of the insertion portion 10. The

The insertion unit 10 has a light emitting unit 11 at the tip. The light emitting unit 11 also has a red LED (Light Emitting Diode) power. By adopting red color, it becomes easy to confirm the contour 43 (see Fig. 4 (c)) of the pressure ulcer pocket 41 where the change in brightness is small before and after insertion under the skin. Electric power is supplied to the light emitting unit 11 via an electric wire 12 as a conducting wire arranged in the insertion unit 10. The electric wire 12 is covered with a tube 13. Electric power is supplied to the electric wire 12 from a dry battery 21 as a supply unit arranged in the holding unit 20. This power is switched on and off by a push-type switch 22. It is desirable to use a switch 22 that can be kept on so that the measurement can be performed with both hands.

[0019] As shown in Fig. 2 (a), the distal end portion of the insertion portion 10 (hereinafter referred to as "tip insertion portion A", see Fig. 1) shows the distance between the tube 13 and the distal force. Scale 17 is displayed by printing. This scale 17 is used to measure the depth of the pressure ulcer pocket 41.

As shown in FIG. 2 (b), in the insertion portion 10, the electric wire 12 is disposed in the tube 13. The wire 12 is inserted into the outer tube 13 after being covered with the inner tube 12a. The tube 13 can also be a flexible material, such as a polyvinyl chloride resin. In the present embodiment, the tube 13 is transparent so that the light from the light emitting portion 11 can escape to the outside. Since the inside can be seen from the outside of the tube 13, the color of the inner tube 12a is higher in contrast to the scale 17. For example, for the black scale 17, a white inner tube 12a is used. However, if the light emitting part 11 is not covered with the tube 13, the tube 13 may be made of an opaque material.

As shown in FIG. 1, a fastener 15 is disposed on the proximal end side of the distal end insertion portion A. As shown in FIG. 3, the fastener 15 is a metal pipe crushed in the radial direction. By holding the electric wire 12, the inner tube 12 a and the tube 13 from the outside, these members are connected to each other. Preventing them from shifting from each other. As a result, the wire 12 and the light emitting part 11 are prevented from coming off from the tube 13, and even if the part ahead of the fastener 15, that is, the part of the tip insertion part A is displaced, it is restored to its original shape with an appropriate force. This function makes it easier to perform the operation when inserting the distal end insertion portion A into the pressure ulcer pocket 41.

Next, a method for using the pressure ulcer pocket measuring instrument 1 will be described.

Prepare a disposable cover 30 with one end closed and the other open, as shown in Figure 4 (a).

. Cover 30 should be disinfected by gas sterilization.

As shown in FIG. 4 (b), the end insertion portion A is inserted into the cover 30 with other end forces. This cover 30 is for keeping the tip insertion portion A clean, and can be prevented from being infected by bacteria between patients by exchanging it every time it is measured.

Next, as shown in FIG. 4C, power is supplied to the light emitting unit 11 using the switch 22 to cause the light emitting unit 11 to emit light.

Next, as shown in FIG. 4 (d), the pressure ulcer pocket 41 of the patient 40 has an opening 42 force, and the distal end insertion portion A together with the cover 30 is inserted into the pressure ulcer pocket 41 from the opening 42. Then, the light emitting part 11 is inserted to the vicinity of the deepest part of the pressure sore pocket 41. At this time, since the light from the light emitting part 11 shows the contour 43 of the deepest part of the pressure ulcer pocket 41, adjusting the position of the light emitting part 11 (i.e. It is possible to prevent the wound from being damaged by applying a strong measuring instrument.

Then, mark 45 is marked with a felt pen along the visualized outline 43. This operation is repeated, and a mark 45 is marked on the entire contour 43 as shown in FIG. 4 (e). Conventionally, the force that can be marked only by a small part by eye measurement If the pressure ulcer pocket measuring instrument 1 of this embodiment is used, the contour 43 can be seen to the periphery of the light emitting part 11, so that the V is wide to some extent. With this, the contour 43 can be accurately marked.

In order to easily measure the size of the pressure ulcer pocket 41, the light emitting part 11 may be applied to the deepest part of the pressure ulcer pocket 41 and the scale 17 may be read.

[0023] Based on the mark 45 described above, the area of the pressure ulcer pocket 41 is measured by measuring the major axis a and the minor axis b orthogonal to the major axis a (the maximum diameter orthogonal to the major axis). Calculate and evaluate size. [0024] According to the pressure ulcer pocket measuring instrument 1 of such an embodiment, the following effects are obtained. First, the contour 43 of the pressure ulcer pocket 41 is visualized by the light from the light emitting part 11, so that the contour 4

Can mark 3 accurately and quickly. Since the measurement can be performed while looking at the contour 43, the wound is not damaged.

And since the electric wire 12 is covered with the flexible tube 13, the wound is hard to be damaged.

. In particular, in the embodiment, since the light emitting portion 11 is also covered with the tube 13, damage to the wound is reliably prevented. Moreover, since the insertion part 10 becomes flexible, it becomes easy to perform measurement regardless of the posture of the patient.

In addition, the scale 17 allows an outline of the size of the pressure ulcer pocket 41 to be grasped at a glance. Further, by using the disposable cover 30, infection by bacteria between patients can be prevented.

As described above, according to the present invention, since the size of the pressure ulcer pocket is accurately determined, it is possible to contribute to the determination of the appropriate direction of pressure ulcer treatment.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be implemented with appropriate modifications. For example, as the conducting wire, not only an electric wire but also an optical fiber can be used. In this case, it is only necessary to attach a component that diffuses the light that is not emitted by the LED as the light emitting part. The supply unit is provided with a light source such as an LED and a power source for supplying power to the LED.

However, considering the brightness of light emission, flexibility, and handling of folding, it is desirable to use electric wires.
