Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for providing information on medical supplies and a method for supplying medical supplies using the same, and particularly to information on medical supplies necessary for treatment or surgery of a diseased part of a patient's body. , The method of providing to a prescribed medical institution,
The present invention relates to a method of supplying necessary medical supplies to a medical institution based on such medical supply information.

[0002]

BACKGROUND ART Conventionally, surgery involving skin transplantation has been performed in order to treat skin diseases, skin defects, skin damage, etc. The method of treatment varies greatly depending on the missing area, damaged area, and their depth.
Therefore, depending on the treatment method, medicines, disinfectants, infusions, gauze, sterilized cloths, compresses, bandages, blades (scalpels, scissors, etc.), gowns, gloves, masks required for surgery and treatment. , Medical materials such as caps, human skin preserved in other households, wound dressing materials, grafts for dermal defects, artificial skin, etc., and their numbers are different.

Particularly, since skin damage due to burns (burns), electric shock, accidents, etc. is unexpectedly taken, a patient is usually brought to a medical institution as an urgent case and urgently treated. If you don't get it, you can't save your life. Therefore, in order to prepare for such an emergency, a medical institution must always secure a large amount of medical supplies, and in general, a large amount of medical supplies including pharmaceuticals are stocked.

[0004] For example, in the case of an urgent patient who has a burn of 50% of the body surface area and weighs 70 kg, 2
In 4 hours, a large amount of lactated Ringer's solution, which is an electrolyte infusion, is required, and according to the "Baxter formula", a value obtained by multiplying the product of body weight (kg) and injury rate (%) by 4 (ml), That is, 14 L (liter) is required. In addition, 1.4L of colloidal solution (fresh frozen plasma etc.)
Also, various medical supplies such as gauze and sterile cloth are required.

However, due to various reasons such as continuous illness, lack of medical supplies necessary for surgery and treatment is often caused in medical institutions (especially in small and medium-sized hospitals for labor saving and cost saving). What is happening is the reality.

In the case of the burns exemplified above, it is necessary to know the injury rate (%) of the patient, that is, the proportion of the injured area in the total surface area, in order to determine the guideline for the treatment such as the amount of infusion solution. However, the injury rate is
Wallace's Law of 9's, Blocker's Law of 5's, Palm area is approximately 1% of the patient's body surface area
“Palm method”, which is calculated as equivalent to “Lund &
It is measured by various known methods such as "Browner's formula". Among them, in particular, the above-mentioned “Lund &Browner's formula” is said to be able to calculate a relatively accurate value, but such a method is complicated, and the injury rate can be quickly obtained. Therefore, the above-mentioned “law of 9” is generally applied to adults and the above-mentioned “law of 5” is applied to young children to calculate the injury rate. -ing However, since the injury rate calculated by such a method is not always accurate, there is an inherent problem that there is a risk of excessive administration of infusion.

[0007] In addition, the condition (severity) of burns is as follows.
It is well known that the damage depth has a great influence in addition to the damage rate as described above. More specifically, the depth of burn is as follows: I degree: damage to epidermis (stratum corneum) only, shallow degree II: damage remaining in superficial part of dermis (basal layer of epidermis), depth II degree: dermis It is classified into damage that reaches the deep part (papillary layer, subpapillary layer), grade III: damage to the epidermis and all layers of the dermis or more. In addition, in grade I and inferior grade II, it is judged that the injury rate is mild enough not to be hospitalized up to about 30%, whereas in infiltrate grade II and grade III, the injury rate is 30%. If exceeded, severe burns will occur and the mortality rate will increase. For this reason, in addition to the above-described injured area, the injured depth must be accurately calculated, and an appropriate treatment suitable for the patient and a medical material applied to it must be appropriately selected. In particular, in shallowness II and deeper depths, the selection of wound dressing, dermal defect graft, artificial skin, etc. applied to the defect wound surface is different. It was necessary to measure and prepare the medical supplies required for the treatment and to prepare them.

[0008] By the way, in the case of a burn having a great depth of injury, early skin transplantation is required. In general, such skin transplantation includes (a) an autologous transplant for transplanting the skin of the patient who receives the skin transplant, (B) Allogeneic (transgenic) transplantation for transplanting human (other) skin of the same species, (c)
There are three methods such as xenotransplantation in which skins of pigs, which are different species, are transplanted. However, except for the autotransplantation described in (a) above, the skin does not undergo permanent engraftment and temporary covering of the defective site of the skin. It is used only as a temporary measure or as an emergency measure. On the other hand, the autologous transplantation of (a) is the most effective method because it transplants the patient's own skin, and thus there is no immune rejection reaction and the transplanted skin is easy to engraft. In order to obtain healthy skin pieces for transplantation from the patient himself,
When the defective surface of the skin extends over a wide area, the limit naturally exists. Therefore, as a substitute for the skin of the patient himself / herself, there is a strong demand for self-cultured skin (artificial skin) obtained by culturing cells of the patient himself / herself, which has no rejection reaction and is capable of permanent engraftment.

However, since skin culturing requires a certain period of time, it is almost impossible to prepare the above-mentioned autologous skin in an emergency.
Generally, wound dressings, grafts for dermal defects, same-preserved human skin (human-preserved human skin), different-preserved skin such as pig skin,
Furthermore, the homogenous cultured skin is appropriately selected and applied temporarily. Among them, the same-preserved human skin and the same-type cultured skin are more preferably selected.

For example, the degree of invasion II and I required for skin transplantation.
When a second-grade patient is brought to a medical institution as an emergency case, the doctor decides a treatment policy while providing first aid. that time,
If the application of homologous preserved human skin or homologous cultured skin is decided, with the consent of the patient or the patient's family, the one stored in the same medical institution, another medical institution or a skin bank will be used. However, at present, allogeneic preserved human skin is very difficult to obtain because it is provided by a deceased human, and homologous cultured skin can be preserved for only a few days. (For example, "Genegraph of Organogenesis", which is licensed in the United States)
5 days, and the cultured epidermal cell sheet of Genzyme Co., Ltd. for 2 days) and the cost is extremely high. Therefore, it is extremely difficult to stock the same kind of human skin and the same kind of cultured skin in a medical institution. Therefore, medical personnel such as doctors and nurses inform the supplier (supplier) of allogeneic skin culture about the size of allogeneic skin skin required for transplantation and have them immediately supply allogeneic skin skin. It will be.

However, at the time of receiving such an order, each medical institution does not always know the size and characteristics of the cultured skin (such as contraction, expansion, and whether or not it can be laminated) after application, Even if the patient's injured area and injured depth are accurately recognized, it is not possible to accurately communicate the size and quantity of the cultured skin required for transplantation, and it takes considerable time for such procedure. There is a problem that it will be required. As a result, there has been a fear that a significant increase in medical expenses for patients may be caused.

The above-mentioned problem is not limited to the case of receiving an allogeneic skin culture in the case of an emergency, and it is not limited to the case of performing a transplantation surgery intentionally using an autologous skin or an allogeneic skin culture. Also, it may occur when the doctor decides the treatment policy with the outpatient and obtains the consent of the patient, and the size and quantity of the cultured skin required for the treatment, and the schedule and the production including the cultured skin. Since the cost and the like are not clear, the doctor often had difficulty in explaining the explanation and could only give a rough answer to the question from the patient.

[0013]

Therefore, the present invention has been made in the background of such circumstances, and the main problem to be solved is to perform non-medical work in medical staff such as doctors and nurses. The purpose of the present invention is to construct a system for ensuring a high medical standard while reducing the above. Among them, in the present invention, image data of a diseased part, a defective part, a wound part or a repaired part of the patient's body is obtained. A method and system for providing information on medical supplies, which can provide medical institutions with information on medical supplies required for treatment or surgery, particularly tissue equivalents such as cultured skin and corneas, simply by sending them.

Here, in order to obtain the surface area of the affected area, for example, the following method can be mentioned as a specific example, but the method is not limited thereto. That is, first, the image data sent from the first terminal 14 is displayed on the display device 30 such as a printer, and based on the image, the affected part of the patient is determined to be the human body having a size closest to the patient's body shape. Draw on the corresponding part of the model (human model). Then, apply an appropriate pattern cloth to the affected area written in the human body model, and draw a line along the affected area or cut the pattern cloth to obtain the surface area of the affected area. .

More specifically, as the pattern cloth, grids are preliminarily attached, and different ones are used for each of the grids, and the number of the grid is used to determine the affected part. Total the number of squared eyes in the part corresponding to the part,
The total number of grids, the surface area of the affected area by multiplying the area per grid, or, or, weigh the pattern cloth cut into an area corresponding to the affected area, it, The surface area of the affected area can be determined by substituting it in a calibration curve that shows the relationship between the weight and the area of the pattern cloth that has been determined in advance. Note that conventionally known aggregation software (for example, Microsoft Excel) may be used for the above-described aggregation and calculation.

Since the surface area of the affected area thus obtained is obtained by using the human body model closest to the body shape of the patient, "law of 9", "law of 5", "palm" Method, "Lund &Broder'sformula" and the like, the measurement error is extremely small. Since the physique of the patient is not necessarily the same as the human body model used, it is desirable to further perform the correction in consideration of the weight of the patient and the like when a more accurate surface area is required.

Then, the surface area of the affected part obtained by the above-mentioned method or the like is inputted from the input device 42 such as a keyboard, so that the treatment surface information obtaining means 54 obtains the treatment surface information. It has become.

Specifically, as shown in FIG. 3 (a), when the affected area is skin, the medical supplies necessary for the treatment of such skin include, for example, auto-cultured skin and homo-cultured skin. The cultivated skin of is selected, and drugs necessary for surgery for transplanting the cultivated skin, antiseptic agents, infusions, wound dressings, dermal defect grafts, gauze, sterile cloths, compresses, bandages, cutting blades, Gowns, gloves, masks and caps are selected. Then, the quantity of the selected medical supplies is calculated according to the treatment surface information such as the surface area of the affected area, and the cost is calculated based on the calculated quantity. Among the cultured skin, in particular, in the case of self-cultured skin prepared by culturing the patient's own cells, the production will be started after the patient's cells are obtained. In addition, the size of the patient's skin required for culturing and the production (supply) schedule, such as the number of days required to produce (supply) a desired amount of auto-cultured skin, etc. are calculated. It will be. And
By inputting the information on the medical supplies selected and calculated in this way from the input device 42 such as a keyboard or a mouse, the medical supplies information acquiring means 56 acquires the information.

As a method of calculating the quantity of medical supplies, for example, when calculating the number of cultured skin, wound dressing, human skin preserved in another family, etc., the affected area 58 is covered in consideration of their characteristics. Is enough to do the smallest number,
Illustrate a method such as dividing the surface area of the affected part 58 by the area per piece of cultured skin, or superimposing a grid having a frame width similar to that of one piece of cultured skin on the image data to make a determination. Can be done.

The medical material information thus obtained is preferably created so as to include a plurality of options according to the state of the affected area, as shown in FIG.

More specifically, in the affected area area table, the medical supplies necessary for the treatment of the affected area and the quantity thereof are stored in association with each other according to the size of the affected area. The production is started after the cells are obtained, the unit price, the time required for production or supply, and the number of sheets that can be produced or supplied, depending on the type of autocultured skin such as epidermal cell sheet or dermal cell sheet, characteristics. While the information on autologous skin such as precautions is stored, the other medical supplies table shows the product name, manufacturer name, unit price, stock amount, etc. according to the type of medical supplies other than the above autologous skin. Records information on medical supplies in Japan.

Then, the medical supplies necessary for the treatment of the surface area (treatment surface information) of the affected area 58 obtained by the treatment surface information acquisition means 54 are obtained from the medical supplies database 84 as described above. Then, the medical supplies information is created.

On the other hand, in the present embodiment, the order determining means 60 in the processing device 22 of the first terminal 14 stores the medical material information received from the second terminal 16 and the medical material stored in advance in the medical institution. Contrast with condition data such as inventory data, number of days until surgery such as skin transplantation, maximum medical expenses desired by patients, medical policy of doctors (for example, using cultured dermal cell sheets during surgery), etc. Is performed to judge whether to place an order or not.

Then, the order content selection / decision means 62 is

At the same time, the order information is sent to the supply command means 70.

As described above, the medical material information providing system 10 and the medical material supplying system 18 having the internal structure of this embodiment as shown in FIG. 7 are used to provide medical material information to a medical institution. The flow of supplying medical supplies is similar to that of the previous embodiment, and the supply of medical supplies information and the supply of medical supplies are performed according to the flow chart shown in FIG. 5 as described above.

Although the representative embodiments of the present invention have been described in detail above, they are merely examples, and the present invention is not limited to the specific description of such embodiments. It should be understood that it should not be construed as limiting.

For example, in the above embodiment, in order to avoid confusion between the information providing organization and the medical material supplying organization, they have been described as different organizations, but as described above, the information providing organization and the medical material supplying organization. It is usually desirable that the institution is the same institution. In addition, when the information providing organization and the medical supplies supplying organization are the same organization, FIG.
It is even more desirable that the second terminal 16 and the third terminal 20 are composed of the same computer, as indicated by 0.

Also, in the above example, the diseased part of the patient's body,
The defect site, the wound site or the repair site was taken by the imaging device 46 installed in the medical institution, but it is not limited to the medical institution and is taken at any place such as an accident site or an ambulance. Is possible. Further, when the image is taken at a place other than the medical institution, the image data need not necessarily be transferred from the first terminal 14 installed in the medical institution to the second terminal 16 installed in the information providing institution. Alternatively, the information may be sent from the shooting site to the information providing organization via the computer network 12.

Further, in the above-described embodiment, the order information is directly transmitted from the first terminal 14 installed in the medical institution to the medical material supply institution, but the medical institution has a plurality of first terminals. When there is the above, such information may be transmitted via the medical supplies procurement section of the medical institution. By adopting such a configuration, it becomes possible for the medical supplies procurement section to collectively manage the order status of medical supplies ordered in the medical institution. Further, the order information transmitted from the medical institution may be transmitted to the medical supplies supplying organization via a wholesale organization such as a pharmaceutical wholesaler. As a result, ordering information from a plurality of medical institutions can be collectively managed, and the medical substance supply organization can more efficiently supply medical supplies.

In addition, in the above-described embodiment, the total surface area of the diseased part, the defective part, the wound part or the repaired part of the patient's body is obtained as the treatment surface information. It is desirable that the depth of damage to the diseased part, the defective part, the wound part or the repaired part and the surface area (surface area for each depth) of each of them be obtained. Specifically, in the case of a burn, I degree, shallow II degree, deep II degree, and I degree
It is desirable that the damage depth such as II degree and the damage area for each depth (surface area for each depth) be obtained. Also,
In addition, from the surface area and the surface area according to depth as described above, the surface area% of the burned body (TSBA: Total Burn Surface Area
The burn index (BI) or the like, which is an index indicating the severity of the burn, may be obtained. The depth of injury may be determined by a medical institution or an information providing institution. When the depth of injury is determined at a medical institution, for example, as shown in FIG. 11, image data in which a boundary line for distinguishing regions having different depths of injury is drawn from the medical institution. It is desirable that it be done by the provider.

Also, in the above example, the treatment surface information acquisition means 5
Although the provisional surface area calculation unit 74 of 4 was designed to obtain the total surface area of the affected area 58, if the affected area is a burn, after detecting the burn area in the same manner as in the above example, It is also possible to distinguish the burn depth by the shade (shade) of the burn site and obtain the surface area for each burn depth. For example, the burn site is binarized with a predetermined threshold value, such as a degree I burn site and a deeper depth site, or a shallower site including shallow degree II burn and a deeper site than that site. The burn depths may be distinguished, and the surface area may be calculated for each burn depth thus distinguished in the same manner as in the above example.

In addition, in the above example, the display devices were installed in all terminals, but in the second terminal and the third terminal,
It does not necessarily have to be installed.

Further, in the above embodiment, the medical supplies to be ordered are selected after it is decided whether or not to place the order, but the present invention is not limited to such a configuration. It is not limited, but of course, after the selection of medical supplies, it is possible to decide whether or not to place an order.

EXAMPLES Hereinafter, representative examples of the present invention will be shown to clarify the present invention in more detail. However, the present invention is not limited by the description of such examples. Needless to say, it is not something to receive.

Example 1-Removal of pigmented black nevus and transplantation of autologous epidermal cell sheet-Surgery for removal of all pigmented black nevus of 17-year-old boy (weight 63 kg), back

First, at a medical institution, a digital camera was used to photograph the pigmented black nevus on the back of the patient together with a 30 cm measure, which is a dimension grasping member, and the image data was taken by a personal computer installed in the medical institution. Input to (first terminal). Next, this image data was sent to the second terminal of the information providing organization by e-mail together with the individual patient data (age, weight).

On the other hand, the information providing organization receives the e-mail from the medical institution and obtains the image data of the diseased part of the patient,
Print it on a printer and put it on a "60 kg adult male life-size model (human body model)" that is the closest size to the patient's physique.
Entered the disease site. Then, in this human body model,
Apply a thin polyester cloth that is poor in elasticity and supple so that there is no bulging, stop the area around the diseased area where it was written with double-sided tape and tacks, and then write the polyester cloth A cut was made along the site and this weight was measured. Then, the obtained weight was compared with a calibration curve, which was obtained in advance and which represents the relationship between the weight of polyester cloth and the surface area, to determine the surface area of the diseased site of the patient. However, since the physique of the patient is not always the same as that of the human body model, the surface area obtained above was corrected in consideration of the difference from the actual weight to obtain the surface area of the diseased part of the patient.

Then, based on the obtained therapeutic surface information (surface area of the diseased site), the size and number of the cultured epidermal cell sheets required for the operation for removing the pigmented black nevus, and
The patient's skin size and skin site required to obtain the cultured epidermal sheet, and the production (supply) schedule and cost required to produce the cultured epidermal sheet were calculated. In addition, medicines, disinfectants, infusions, gauze, sterilized cloths, compresses, bandages necessary for this surgery and treatment,
Medical supplies information was obtained by calculating the recommended items and quantity of cutting blades (scalpels, scissors, etc.), gowns, gloves, masks, caps, and wound dressings, and their costs. As the medical supplies information, the size and the number of the cultured epidermal cell sheets, characteristics, and the necessary items and quantities of the other medical supplies required after the supply possible date of the cultured epidermal cell sheets are adopted, The information about the number of the cultured epidermal cell sheets and the information on the surface of the treatment such as the surface area of the affected area are attached.

Then, the medical material information thus obtained is transmitted to the medical institution through the Internet, and the information is displayed at the medical institution, whereby the information on the medical material necessary for the operation is provided. .

As a result, a busy doctor or nurse can take a picture of the affected part of the patient at the time of outpatient consultation and send it to a predetermined information providing organization to obtain information such as the quantity and cost of necessary medical supplies. , It will be possible to obtain with certain accuracy. As a result, it is possible to explain the treatment to the patient during the outpatient examination.

Further, if necessary medical supplies are ordered on the Internet from the obtained medical supplies information, the necessary medical supplies can be easily procured. Therefore, in the medical institution, it is possible to reduce the complicated inventory holding and the paperwork, and it becomes possible for the doctor and the nurse to concentrate on the medical treatment. Further, normally, it becomes possible to use materials such as an extremely expensive cultured epidermal cell sheet without excess or deficiency, and waste can be eliminated.

Example 2 After a burn patient was transported to a medical institution, the injured part was first washed and disinfected, and then the affected part was photographed with a digital camera. At that time, the ruler, which is a dimension grasping member, is included in all the image data to be photographed. Then, the image data is transferred via the storage medium of the digital camera to
After importing into a computer (first terminal) installed in a medical institution, the personal data (age, weight, sex) and the personal data of the patient were transferred by e-mail to a manufacturer, which is an information provider and a medical supplies provider.

On the other hand, the manufacturer receives the electronic mail from the medical institution at the computer (second terminal) and outputs the image data of the affected part of the patient with the image processing software: NI.
Using H image (software provided free of charge by NIH, USA), the surface area of the affected area was determined by tracing the affected area with a mouse. Further, by binarizing the image data with such image processing software, the burn depth of the affected area was determined according to the shade (shading) of the affected area, and the surface area for each depth was also obtained.
The binarization was performed at the boundary between the shallow depth II burn and the deep depth II burn and the boundary between the deep depth II burn and the third depth burn. Further, when determining the surface area of the affected area and the surface area by depth, the correction data derived by the sex, height, and weight of the patient were used.

Then, based on the obtained treatment surface information (surface area of diseased part, surface area according to depth), the computer of the second terminal makes the medical supplies necessary for the treatment of burns, their size, number of sheets, supply schedule. , Calculate the cost,
The medical supplies information as shown in FIG. 12 was acquired. In addition,
When obtaining information on medical supplies, apply the same type of skin to the deeper part of the inferiority II degree or higher, apply the autologous cultured epidermis to the areas of inferiority II and III, and the total burn area. To the computer (second terminal) in advance, necessary data can be prepared so that a choice of contents such as applying a wound dressing: Sofratulle (gauze-like dressing; manufactured by Yamashita Roussel) can be made. I gave it.

Then, the information on the medical supplies thus obtained was transmitted to the medical institution through the Internet, and the information was displayed at the medical institution, so that the information on the medical supplies necessary for the surgery was provided. .

As a result, in a medical institution, it takes only a minute time from the transmission of the image data to the acquisition of the information on the medical supplies. Therefore, the treatment policy can be determined very quickly as compared with the conventional method. Was possible.

If the burned patient is taken to the medical institution immediately after the treatment, the healthy skin of the patient is taken and transported to the manufacturer of the cultured skin. In Japan, by the next day, it will reach the manufacturer and the production of auto-cultured skin can be started immediately. Therefore, medical institutions can immediately set up treatment and surgery schedules according to the supplied medical supplies, and manufacturers can immediately prepare for production.

On the other hand, conventionally, after a patient similar to that in the above-mentioned second embodiment is transported to a medical institution and subjected to appropriate treatment, a telephone call “from right shoulder to waist, invasion II The manufacturer, which is an information provider and medical supplies provider, receives an order for the production and shipment of auto-cultured skin and homo-cultured skin, which is the request for shipping of homo-cultured skin and production of auto-cultured skin. However, the patient's burn area was not clear, and more clear material had to be requested.
Then, obtain a burned part on the human body diagram by hand, calculate the burned area,
From the surface area thus obtained, the required number of auto-cultured skins or allogeneic cultures, etc. were calculated. However, in such a handwritten drawing, it is not possible to obtain an accurate surface area as in Example 2 above, and between the calculated number of cultured skins and the number of actually used cultured skins, There was an excess and deficiency.

[0125] Further, it takes a considerable amount of time from when the medical institution is contacted to when the information such as the number of cultured skins necessary for treatment is provided to the medical institution. Offering was difficult. Moreover, in medical institutions, after receiving such information, they often consult with the patient or the patient's family regarding the medical policy, so it often takes several days before the actual order is placed. In addition, medical institutions have little knowledge about the size of wound dressing and cultured skin, the cases approved by the Ministry of Health, Labor and Welfare, and the number of times they are applied, so not only must they be explained, but insurance approval is required. Because of the low awareness of the adapted cases, this explanation was necessary and more time had to be spent.
