Background

In general, various medical wastes are generated in hospitals, health care facilities, nursing homes for the elderly, and the like. These medical wastes include disposable syringes, cotton or gauze for wiping blood or secretions, bandages, used diapers, human excrements, and the like. Medical waste is mostly contaminated with pathogenic bacteria and risks of causing infection, and it is necessary to prevent risks of causing secondary and tertiary infections and block offensive odors by comprehensive waste management, and it is generally collected by a special company and treated by incineration, chemical treatment, landfill, or the like.

In addition, with the recent increase in elderly population, the number of nursing facilities has increased, and the amount of medical waste discharged has also increased proportionally. However, the waste treatment enterprises have a limited treatment capacity, and the nursing facilities themselves incur expenses in terms of the treatment of waste, so that medical waste is stolen and discarded together with general waste or placed in an open place.

In particular, in the case of an elderly nursing facility, since there are many patients who cannot move or who are demented, the amount of diapers to be used is large. The diaper is used for receiving the excrement of a patient, so that the odor is heavy, and therefore, if the diaper is not completely treated, the surrounding environment is damaged, and the discomfort is brought to people, and particularly, the problem of the generation of worms such as maggots and the like is caused for a long time. Used diapers should not be thrown away in a state of not being opened after being rolled up with difficulty, but should be disposed of more hygienically by using a special device.

As a prior art for sanitary disposal of diapers, there has been proposed a diaper packaging device having a deodorizing function of Korean patent laid-open publication No. 10-1775523. However, the conventional medical waste disposal apparatus has a disadvantage that bad smell may be emitted and waste may leak to the outside due to poor sealing of the waste. Further, when the internal pressure is increased by the gradual decay and the expansion is caused, the sealing function is completely lost because a part of the membrane is burst.

Also, a battery 28 and a seal cut portion 30 are provided inside the case 20. The battery 28 is a charging type power supply portion that supplies power required for the passage switching portion or the seal cutting portion 30. The description of the seal-cutting portion 30 will be described later.

The needle recovery box 23c is a recovery bucket that receives and accommodates the injection needle separated from the used syringe, and is located at the lower portion of the needle separating portion 21 e. The syringe needle 51 separated from the needle separating portion 21e falls downward and is collected in the needle collecting box 23 c. The needle recovery tank 23c can also be opened or closed in a drawer-type manner.

The needle separating portion 21e is a hole penetrating a side wall surface formed in the housing 20 and separating the injection needle from the syringe, and has a needle passing hole 21c and a catching groove 21 d. The needle head passage hole 21c is a hole through which the needle head 51 passes, and the catch groove 21d is a catch portion for catching and fixing the needle plug 51a of the needle head.

For the convenience of explanation, the structure of the general syringe 50 will be explained first. The syringe 50 is composed of a syringe 53 containing a medicine and having a projection 53a formed at the tip end thereof, and an injection needle 51 fitted over the projection 53 a. A pintle 51a coupled to the protrusion 53a is integrally fixed to a rear end portion of the injection needle 51. The diameter of the pintle 51a is greater than the maximum spacing of the bayonet 21 d.

To separate the needle 51 by the needle separating portion 21e, the needle 51 is first completely inserted into the housing 20 through the needle passing hole 21c and then lowered downward so that the protrusion 53a is caught in the catching groove 21 d. When the projection 53a is caught in the catching groove 21d, the pintle 51a of the injection needle 51 is positioned rearward of the catching groove 21 d. In this state, when the cylinder 53 of the syringe is pulled horizontally, the pintle 51a is caught by the catch 21d and is separated from the projection 53 a. The separated injection needle 51 is dropped downward and contained in the needle recovery tank 23 c.

The upper plate 22 is rectangular, and is connected to the upper portion of the housing 20 by a hinge 22f, and an opening handle 22g is provided on the opposite side of the hinge 22 f. When the opening handle 22g is grasped and pulled in the direction of arrow a, the upper plate 22 is rotated upward, and the upper portion of the housing 20 is opened. The film supply part 40 can be replaced by opening the upper plate 22.

A feed passage 22a is formed on one side of the upper plate 22. The input passage 22a is a hole through which medical waste (Z of fig. 6) to be treated passes downward. Meanwhile, the control unit 25 is located on the side of the input passage 22 a. The control unit 25 outputs a control signal for controlling a channel switch unit and a seal cutting unit, which will be described later, and includes a plurality of switches 25 a.

The channel opening/closing section functions to open or close the input channel 22a in a state of being positioned below the upper plate 22, and its structure is shown in fig. 3. As shown in fig. 3, the passage switching section has a pair of side rails 22b, a movable plate 26, and a switching motor 22 e.

The side rails 22b are linear members fixed in parallel to both sides of the bottom surface of the upper plate 22, and support the movable plate 26 so that the movable plate 26 can slide. The input passage 22a is opened or blocked by the sliding movement of the movable plate 26. The movable plate 26 is a rectangular member, and is linearly moved by the opening and closing motor 22e in a state where both ends in the width direction are supported by the side rails 22 b.

In order to convert the rotational force of the switching motor 22e into the linear motion of the movable plate 26, a pinion 22m may be attached to a driving shaft of the switching motor 22e, and a rack (not shown) may be used for the movable plate 26. The rack positions can be fixed to the bottom surfaces of both ends in the width direction of the movable plate 26.

Further, a film supply section 40 and a seal cutting section 30 are provided below the input passage 22 a.

Fig. 3 is a partial perspective view for explaining the structure of the film supply part 40 and the seal cutting part 30 inside the housing 20 shown in fig. 2. Fig. 4 is a sectional view taken along line a-a of fig. 3.

The film supply unit 40 accommodates and supplies a plastic film 43 for wrapping the medical waste Z, and as shown in the drawing, is composed of a film case 41 in a four-frame shape and a film 43 for filling the film case 41.

The film 43 used in this embodiment has a certain sectional shape in the longitudinal direction to be fitted into the film case 41 in a state of being cut into a desired length. Both ends of the film 43 are open.

Fig. 5 (a) is a perspective view showing a film 43 used in the sealed discharge device 10 according to the embodiment of the present invention, and fig. 5 (b) is a view showing the film 43 shown in fig. 5 (a) being housed in the housing body 41 a.

As shown in fig. 5 (a), the film 43 has a tubular shape with both ends open, extending in the longitudinal direction. When one end of the film 43 is tightened and then inflated by introducing air into the film, the film takes the shape of a cylinder or a tube. In fact, the film in this shape can also be a semi-finished product before the plastic bag is made.

As shown in fig. 5 (b), the film 43 is folded from the lower end portion thereof into a zigzag shape and filled in the housing space 41c of the housing body 41a in a state where the lower end portion is inserted into the housing body 41 a. In particular, the lower end portion of the film 43 is drawn out from the lower portion of the film case 41 to seal the lower end portion. The sealed portion at the lower end portion is an upper welded portion 43 a. As shown in fig. 8, the upper welding portion 43a is a portion formed by the upper welding heater 35a, and prevents the medical waste Z from falling out to the lower portion. The description of this will be described later.

The film case 41 is composed of a case body 41a and a cover 41 e. The housing body 41a provides an accommodation space 41c with an open upper portion, and has a drawing slit 41b on a lower side. The drawing slit 41b is a passage for drawing the lower end portion of the film 43 filled in the housing space 41c downward.

The cover 41e is coupled to the upper portion of the housing body 41 a. When the membrane 43 is completely exhausted, the cover 41e may be opened to refill the membrane 43 into the housing body 41 a.

The seal-and-cut unit 30 is provided at a lower portion of the film supply unit 40, and functions to draw the film containing the medical waste downward, seal the film by heat-welding the film, cut the heat-welded portion, and discharge the film to the lower portion. The seal cutting part 30 is located at an upper portion of the waste collection box 23 a.

Fig. 6 to 9 are sectional views for explaining the internal structure and operation of the seal cutting part 30 of fig. 3.

As shown, the seal cutter 30 includes: a sealed chamber 31 providing a nip space 31 a; a pair of discharge doors 32 provided at a lower portion of the sealing chamber 31; a door opening and closing unit; a support plate 33, a pressing sponge 34, a space adjuster 37, a welded part, a cut part, and a film stretching unit in the pressing space 31 a.

The seal chamber 31 is open at the top and bottom and is disposed in a box-shaped casing below the input passage 22a in the plumb direction. The film supply portion 40 is disposed between the nip space 31a of the sealed chamber and the input passage 22 a. Medical waste introduced from the outside through the introduction passage 22a is lowered in a state of being mounted on the film 43 of the film supply portion 40, and then enters the nip space 31 a.

The discharge gate 32 is connected to a lower portion of the hermetic chamber 31, and is opened or closed by a gate opening and closing unit. The discharge gate 32 will be described first with reference to fig. 10 (a) and (b).

As shown in fig. 10 (a) and (b), the discharge gate 32 is formed in a pair of two, and is connected to the lower end of the seal chamber 31 by a support pin 32 d. The discharge gate 32 rotates in the direction of arrow b or the opposite direction around a support pin 32 d.

If the discharge door 32 is rotated upward to close the lower portion of the sealing chamber 31, the nip space 31a of the sealing chamber 31 is sealed. When the discharge door 32 is rotated downward and opened, the medical waste subjected to the sealing treatment falls into the waste collection tank 32a on the lower side.

The door switch unit has a door hinge 32b functioning to open and close the discharge door 32 and an electric door switch 38. The door hinge 32b is a member fixed to both end portions of each discharge door 32, which shares the support pin 32d, and extends in a direction away from the discharge door 32.

The electric door switch 38 includes an air cylinder 38a and a reciprocating lever 38 b. The door switch 38 reciprocates the reciprocating lever 38b in the length direction by the power supplied from the battery 28. For the linear motion of the reciprocating rod 38b, a ball screw or a linear motor may be used in the cylinder 38 a.

The cylinder 38a of the door switch 38 is connected to the bracket 31e by a pin 31f, and the end of the reciprocating lever 38b is connected to the extended end of the door hinge 32b by a lifter 32 c. As shown in fig. 2, the lift lever 32c is a circular rod-shaped member extending in the horizontal direction. The door switch 38 receives a signal from the control unit 25 to open or close the discharge door 32.

In addition, the film stretching unit performs a function of pulling out the film 43 by operation in a state where the discharge door 32 is closed. In particular, a negative pressure is used to elongate the membrane 43 towards the lower part. In detail, the pressure of the lower space of the membrane 43 shown in fig. 6 is induced to be smaller than the pressure of the upper space of the membrane 43, that is, so that the pressure of the nip space 31a is smaller than the pressure of the upper space of the membrane 43. If the pressure in the pressure-bonding space 31a is kept lower than the atmospheric pressure, the film 43 is pulled to the lower portion by the force corresponding to the pressure difference, and is discharged to the lower portion of the film housing 41 to be located between the pressure-bonding sponges 34.

The film stretching unit has a plurality of fans 32a for sucking out air inside the nip space 31a toward the lower portion. The fan 32a draws the film 43 downward from the film housing by reducing the pressure of the nip space 31a, and the operation timing and the rotation speed of the fan 32a are controlled by the control section 25.

A sensor 55 is disposed inside the sealed chamber 31. The sensor 55 functions as the detection film 43. That is, when the film 43 is pulled out downward by the fan 32a, the film 43 is detected to prevent the film 43 from being further pulled out. The detection signal of the sensor 55 is transmitted to the control unit 25, and the control unit 25 stops the fan 32a at the moment of receiving the detection information from the sensor, thereby preventing the film 43 from being further elongated. Eventually, the membrane 43 only descends to a level that is level with the sensor 55, thereby preventing waste.

The support plates 33 are rectangular plates having a predetermined thickness, and are arranged in two opposite directions with a nip space 31a therebetween. Of the two support plates 33, the left support plate 33 in the drawing can be reciprocated by the pitch adjuster 37, and the right support plate 33 is fixed to the inner wall surface of the sealed chamber 31. Of course, the pitch adjuster 37 may be connected to the right support plate 33 to be capable of reciprocating movement as needed.

Reference numeral 31b denotes a guide rod. The guide rod 31b is a round bar-shaped member for guiding the linear motion of the support plate 33, and extends in the horizontal direction.

The pitch adjuster 37 is composed of a main body 37a and an operating lever 37b, and operates by receiving electric power from the battery 28. The body 37a may employ a linear motor or a ball screw to reciprocate the operation rod 37b by receiving power of a battery.

The pressing sponge 34 is fixed to the opposite surfaces of the support plates 33 and has a certain thickness. As shown in fig. 8, the pressing sponge 34 functions to press the medical waste Z (in a capsule-wrapped state) located in the pressing space 31 a. The medical waste Z is pressed to reduce the volume and is closely attached to the periphery of the medical waste Z by laminating two films. The reason why the film is closely attached is to weld and cut the film. The hardness of the compression sponge 34 may vary as desired.

An upper welding heater 35a, a lower welding heater 35b, and a blade 36 are provided above the pressing sponges 34. The upper welding heater 35a and the lower welding heater 35b extend in the horizontal direction, have heater wires inside, and generate heat by electric power applied from the battery 28 to thermally weld the film 43. The upper welding heater 35a and the lower welding heater 35b are spaced in parallel, and a blade 36 is provided therebetween.

The blade 36 is a cutting edge for cutting the film in a state fixed by the upper welding heater 35a and the lower welding heater 35 b. That is, the upper welded part and the lower welded part are cut by cutting the film. Of course, other forms of cutting units capable of cutting the film 43 may also be used.

The medical waste sealed discharge apparatus 10 having the above-described structure operates as follows. First, the movable plate 26 is opened by pressing the switch 25a of the control unit 25, and then the medical waste Z is introduced through the opened introduction passage 22 a. The movable plate 26 is closed after the medical waste Z is thrown in.

The medical waste Z thus introduced is loaded into the prepared film 43. In this case, the film 43 is received by the upper welded portion 43 a. As shown in fig. 8, the upper welding portion 43a is a portion welded by the two upper welding heaters 35a, and is formed when the medical waste Z input before disposal is disposed, or belongs to a portion welded by the upper welding heater 35a after the lower end portion of the film 43 is pulled downward (in the case where the film 43 is refilled into the film housing 41).

Next, the fan 32a is activated to suck out the air inside the nip space 31a to the lower portion so that the pressure of the lower space of the film 43 is less than the atmospheric pressure, thereby forming a negative pressure environment. As the pressure of the nip space 31a decreases, the film 43 is pulled down together with the medical waste and is positioned between the nip sponges 34, as shown by the broken lines in fig. 7.

When the medical waste Z descends through the above-described process, the fan 32a is stopped, and the support plate 33 on the left side in the figure is pressurized and conveyed in the direction of the arrow f in the figure. As the support plate 33 is moved in the arrow f direction, the medical waste Z wrapped by the die 43 is pressed by the sponge. Wherein the sponge is elastically deformed by the reaction force of the medical waste.

Finally, as shown in fig. 8, when the upper welding heater 35a and the lower welding heater 35b on both sides are brought into close contact with each other through the film 43, the interval adjuster 37 is stopped, and the upper welding heater 35a and the lower welding heater 35b are simultaneously activated to weld the films. The film on top of the medical waste is formed into two melt lines. The welding line formed by upper welding heater 35a is upper welding portion 43a, and the welding line formed by lower welding heater 35b is lower welding portion 43 b.

At the moment when the upper welding heater 35a and the lower welding heater 35b are brought into close contact with each other, the blades 36 also intersect with each other to cut the film. The blade 36 cuts between the upper welded part 43a and the lower welded part 43 b.

After the welding and cutting are completed, the left support plate 33 is retracted in the arrow g direction, and the discharge door 32 is opened. The medical waste Z subjected to the film sealing treatment is collected in the waste collection box 23 a. The manager collects the waste collected in the waste collection tank 23a and appropriately handles the waste.

The present invention has been described in detail with reference to the specific embodiments, but the present invention is not limited to the embodiments, and those skilled in the art to which the present invention pertains can make various modifications within the scope of the technical idea of the present invention.
