Description

  The present invention relates to a waste liquid measuring bag suitable for use in a waste liquid treatment system for waste liquid discharged from a human body.

  In modern medical operating rooms, waste fluid (urine, blood, etc.) discharged from the human body (patients during surgery, etc.) is stored in a waste fluid storage bag via a waste fluid tube, and every fixed time (approximately 5 minutes during surgery). Every hour, about 20 minutes or every hour at the bedside, the amount of storage is measured in time series. In addition, the amount of waste liquid is monitored for patients who are required to rest. This is because the variation in the amount of waste liquid is important physiological data for knowing the progress of the operation and the health condition of the patient as well as blood pressure, body temperature, and pulse.

An example of such a waste liquid storage bag is JP-A-2002-34958. As shown in FIG. 6, the conventional waste liquid storage bag includes a bag body 62 made of a transparent material having a scale 61 printed on the surface thereof. The waste liquid discharged from the human body passes through the waste liquid inflow portion 63. Inflow. This conventional waste liquid storage bag is usually provided with a hanging tool 64 for hanging on the side of the operating table or the bed, and the nurse lifts the waste liquid storage bag by hand and measures the position of the liquid level when measuring regularly. And the amount of storage is recorded on a predetermined recording sheet. Further, the waste liquid stored in the waste liquid storage bag is discharged from the discharge unit 65 or the entire bag is discarded.

  However, in the above-described conventional waste liquid storage bag, when measuring the amount of storage, urine or the like must be looked at repeatedly, which is not only uncomfortable, but especially in the case of urine, the weight increases and the physical burden is increased. In addition, there was a problem that visual measurement had a large error. Further, the conventional waste liquid storage bag has a quadrangular shape as shown in the figure, and at the initial stage of storage, there is a serious problem that the liquid may be inclined toward one corner and accurate measurement cannot be performed. .

  In view of the above points, the present invention measures the amount of waste liquid to be stored with a weigh scale without touching or directly looking at the waste liquid storage bag. It is an object of the present invention to provide a waste liquid measuring bag that can always perform accurate measurement without causing any trouble.

  In order to achieve the above object, the waste liquid measuring bag according to the present invention includes a waste liquid storage portion including an inflow portion of waste liquid discharged from the human body and a discharge portion of stored liquid below the suspension portion of the weighing scale. And the bottom of the waste liquid storage part is formed in a semicircular shape so that the bag does not tilt even in the initial stage of waste liquid storage.

  The waste liquid measuring bag according to claim 2 is characterized in that the waste liquid storage part is formed by stacking a front sheet and a back sheet and thermally welding a boundary part between a peripheral part and a suspension part. The bag itself was configured to be flat.

A pinch and a sheath for storing the tip of the tube are provided. The waste liquid is not disturbed during storage, and can be discharged by a simple operation when the waste liquid is discharged.

  According to the present invention, it is used by suspending a weight scale installed near a patient's bed during or after surgery (during a medical treatment period) to record changes in the weight of waste liquid discharged from the patient in time series measurement. Since the bottom part is formed in a semicircular shape so that the bag does not tilt even at the beginning of measurement, i.e., at the beginning of waste liquid storage, accurate measurement values can be obtained without causing weighing errors in the weighing scale. There are benefits to be gained. Moreover, since the visual measurement by the nurse is not required, the working environment for measuring the amount of waste liquid is greatly improved, and the medical data of the waste liquid discharged from the patient during or after surgery (during the treatment period) Various excellent effects such as improvement of reliability can be obtained.

  Further, according to the invention described in claim 2, the waste liquid container is formed by stacking a front sheet and a back sheet and heat-welding a boundary part between the peripheral part and the suspension part. Therefore, the bag itself is flattened, and an excellent effect is obtained that is advantageous for storage and storage.

  Furthermore, according to the invention described in claim 3, the waste liquid discharged from the human body is applied to a plastic molded product in which the inflow part of the waste liquid is welded around a through hole provided in the upper surface sheet of the waste liquid storage part. It is characterized by being able to store once, so that the front and back sheets that are in close contact with each other can be separated by the flow down force of the stored waste liquid, and in particular, the inflow of waste liquid at the initial stage is smooth. It is effective.

  Furthermore, according to the invention described in claim 4, the waste liquid discharge section can clamp and release the tube having the base end penetrating and joined to the front sheet at the bottom of the waste liquid storage section, and the intermediate section of the tube. Since it has a pinch and a sheath part for storing the tube tip, it does not get in the way while the waste liquid is stored, and it is easy to operate when discharging the waste liquid, that is, the tube tip is taken out from the sheath part. It has an excellent effect that the waste liquid can be discharged toward a certain disposal site simply by opening it from the pinching tool.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 is a front view of the waste liquid storage bag of the present application, FIG. 2 is a side sectional view of the same, FIG. 3 is a perspective view showing a use state, FIG. 4 is a side view showing a hook hanging from a weighing scale, and FIG. It is a side view of a tool.

  In the figure, reference numeral 1 denotes a bag of the present application, and the bag 1 of the present application has a suspension portion 2 to a hook 33 provided at a lower end portion of a shaft 32 suspended from a weight scale 31, as shown in FIG. A storage unit 3 for waste liquid discharged from the human body (patient) is provided below the unit 2. The waste liquid storage part 3 has a bottom part 4 formed in a semicircular shape as shown in FIG. This is because the corner portion where the waste liquid is stagnated is not formed. A waste liquid inflow portion 5 discharged from the human body is provided above the housing portion 3, and a waste liquid discharge portion 6 is provided in the semicircular area of the bottom portion 6.

  A shaft 32 hanging from the weighing scale 31 is provided with a coupling portion 32 ′ made of a screw or the like at an upper end portion, and is detachably coupled to a measurement main portion 31 ′ built in the weighing scale 31. A hook 33 having a U-shaped cross section is attached (fixed) to the front surface of the lower end of the shaft 32 in a T shape.

  As shown in FIGS. 1 and 2, the present application bag 1 has a front sheet 1 a and a back sheet 1 b overlapped, and a peripheral edge portion E and a boundary portion B between the suspension portion 2 and the waste liquid storage portion 3 are linearly welded. Do it. The thermal welding of the peripheral portion E may be formed by a fusing (cutting simultaneously with the thermal welding) method.

  The suspension portion 2 is provided with a horizontally elongated hole 2 a for engaging with a lower end hook 33 of a shaft 32 suspended from the weighing scale 31. The upper edge side and both end edge sides of the horizontally elongated hole 2a are edged by a heat welding wire 2b in order to increase the strength. Further, in order to increase the strength of the suspension portion 2, a horizontally long bag 2c is provided along the upper edge, and the aggregate 2d is accommodated in the bag 2c. Needless to say, the bag 1 of the present application that is locked to the lower end hook 33 of the shaft 32 hanging from the weighing scale 31 is maintained in balance.

  The semicircular shape of the bottom 6 of the waste liquid storage part 3 may not be a true semicircle as long as it is an arc that does not form a corner where the waste liquid stagnates. The storage capacity of the waste liquid storage unit 3 is sufficient if it is about 2500 to 3000 ml, but the maximum storage capacity can be determined freely. Note that a scale 3 'for visual measurement may be provided on the surface of the waste liquid storage unit 3 for convenience.

  As shown in FIG. 2, the waste liquid inflow portion 5 has a plastic molded product 8 welded around a through hole 7 provided in the upper surface sheet 1 a of the housing portion 3. The molded product 8 is provided with a tube connecting pipe 9 and an air vent pipe 9 'penetrating on the upper surface thereof. The outer end of the tube connection pipe 9 is connected to a waste liquid tube 10 that guides the waste liquid discharged from the human body. That is, the waste liquid discharged from the human body is temporarily stored in the molded product 8 through the waste liquid tube 10, obtaining a constant flow force, and separating the front sheet 1 a and the back sheet 1 b that are in close contact with each other through the through holes 7. It can flow into the housing part 3. In this case, if a downward inclined surface 8a is formed on the front side of the molded product 8 (opposite surface of the through hole 7) as shown in the drawing, the flow force increases in the waste liquid in the molded product 8 and the smoothness is smoother. It can be made to flow. The air vent pipe 9 'is for preventing the molded product 8 from being evacuated.

  The waste liquid discharge portion 6 includes a discharge tube 11 made of an elastic material such as rubber having a base end penetrated to the front sheet 1a corresponding to the semicircular region of the bottom 6 of the storage portion 3, and a base edge of the front sheet 1a.

The base end portion of the discharge tube 11 is bent by the cover body 14 along the surface of the front sheet, and the distal end 11a is stored in the sheath portion 13 when the waste liquid discharge portion 6 is in the waste liquid processing operation or the present application bag. This is because it is not bulky (not disturbing) during storage and storage.

  As shown in FIG. 5, the clip 12 is formed by forming a slit 12c having a narrow groove portion and a large diameter portion in a frame body 12b obtained by joining a base edge 12a to a front sheet 1a of the housing portion 3. Thus, when the discharge tube 11 is in the narrow groove portion 12c ′ of the slit 12c of the frame 12b, the discharge tube 11 is clamped to stop the flow of the liquid and moved from the narrow groove portion 12c ′ to the large diameter portion 12c ″. In the example shown in the drawing, the base edge 12a of the clip 12 is on the long side, and a slit 12c having a narrow groove and a large diameter portion is in the vertical direction. However, the base edge 12a may be on the short side, and the slit 12c having the narrow groove portion and the large diameter portion may be in the front-rear direction.

  Therefore, when the waste liquid from the human body is stored in the waste liquid storage section 3 via the waste liquid inflow section 5, the waste liquid discharge section 6 is initially closed. That is, the intermediate portion of the discharge tube 11 is clamped by the narrow groove portion of the slit 12 b of the sandwiching tool 12, and the tip is stored in the sheath portion 13. Therefore, when the waste liquid in the waste liquid storage part 3 is discarded because the waste liquid storage part 3 becomes full or the like, first, the tip of the discharge tube 11 is first pulled out from the sheath part 13 and strongly picked with fingers, and in this state the discharge tube 11 is moved to the large diameter portion of the slit 12c of the clip 12 and the tip of the tube that has been picked with fingers is opened toward the disposal location.

  The weight scale 31 is installed on a table 34. The table 34 has its four leg portions 35 kept horizontal by adjusting the operation panel 36 ′ of the height adjuster 36. Thus, the lower end hook 33 of the weighing scale 31 is suspended through a through hole 34 "provided in the top plate 34 'of the table 34 (see FIG. 4).
