Description

本発明は、血液透析治療にかかる患者の体重を測定するための体重測定装置に関するものである。   The present invention relates to a weight measuring apparatus for measuring the weight of a patient involved in hemodialysis treatment.

一般に、血液透析治療は、患者の血液を体外循環させつつ浄化及び除水（血液中の水分除去）するのであるが、かかる除水の際の水分除去量（除水量）は治療前の患者の体重からドライウェイトと呼ばれる基準体重を差し引くことにより算出される。そのため、血液透析治療にかかる患者は、治療前（血液透析治療の確認のために治療後にも行う）に必ず体重を測定することとなる。   In general, hemodialysis treatment purifies and removes water (removing water in the blood) while circulating the patient's blood extracorporeally. It is calculated by subtracting a reference weight called dry weight from the weight. For this reason, patients who undergo hemodialysis always measure their body weight before treatment (also after treatment for confirmation of hemodialysis treatment).

然るに、体重測定の際、パジャマ、サンダル又は杖を患者が身に付けて行うことが多く、或いは義手や義足を装着した患者もいるので、測定された重量が必ずしもその患者の真の体重であるとは限らない。また、自力で体重測定装置に乗れない患者の場合、車椅子に乗った状態で体重測定を行うこともあり、車椅子の重量が加算されてしまうことから、この場合であっても測定された重量が必ずしもその患者の真の体重であるとは限らない。   However, the patient often wears pajamas, sandals, or a cane when measuring body weight, or some patients wear a prosthetic hand or a prosthetic leg, so the measured weight is not necessarily the true weight of the patient. Not necessarily. In addition, in the case of a patient who cannot ride on the body weight measurement device by himself, the weight measurement may be performed in the state of riding in the wheelchair, and the weight of the wheelchair is added. It is not necessarily the true weight of the patient.

このように、パジャマ、サンダル、杖、義足、義手或いは車椅子といった患者の身体以外のものであって体重測定の際に当該患者と共に測定される種々の付随物は、患者の真の体重を測定する妨げとなるため、当該付随物の重量を考慮して患者の真の体重を求める必要がある。そこで、従来、体重測定の際には、作業者が付随物の種類やその重量を確認し、測定された重量（患者及び付随物の重量）から確認された付随物の重量を差し引くことにより、患者の真の体重を求め、血液透析治療の際の除水量を算出していた。尚、かかる先行技術は、文献公知発明に係るものでないため、記載すべき先行技術文献情報はない。   In this way, various appendages that are not the patient's body, such as pajamas, sandals, walking sticks, prosthetic legs, prosthetic hands, or wheelchairs, and are measured together with the patient during weight measurement, measure the patient's true weight. Since this is an obstacle, it is necessary to determine the true weight of the patient in consideration of the weight of the incidental. Therefore, conventionally, when measuring body weight, the operator confirms the type and weight of the accessory, and subtracts the weight of the associated accessory from the measured weight (the weight of the patient and the accessory), The true body weight of the patient was calculated and the amount of water removed during hemodialysis treatment was calculated. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

しかしながら、従来の体重測定装置においては、作業者が付随物の種類やその重量を確認する必要があったため、手間がかかってしまうことから、体重測定に時間がかかってしまうという問題があった。特に、一般的に血液透析治療前後の体重測定は、同室に複数の患者が出入りして順次行われるため、体重測定に時間がかかってしまうと患者の入退室が滞り、スムーズな体重測定を行うことができない。また、従来においては、作業者が付随物を確認する必要があることから、当該付随物の有無や種類の判断を誤ってしまうと、再度の体重測定を行う必要があり、患者に過度の負担を強いてしまうという問題もあった。   However, in the conventional weight measuring apparatus, since it is necessary for the operator to check the type of the accessory and its weight, it takes time, and thus it takes time to measure the weight. In particular, body weight measurement before and after hemodialysis treatment is performed sequentially with multiple patients entering and exiting the same room, so if it takes time to measure the body weight, the patient's entrance and exit will be delayed, and smooth weight measurement will be performed. I can't. In addition, in the past, since it is necessary for the operator to check the accompanying items, if the presence or type of the accompanying item is mistakenly determined, it is necessary to measure the weight again, which is an excessive burden on the patient. There was also a problem that forced it.

本発明は、このような事情に鑑みてなされたもので、付随物の重量を含む固有情報を読み取って患者の真の体重を自動的に演算することにより、患者の真の体重をスムーズに求めることができるとともに、作業者による付随物の有無や種類の判断ミスを回避することができる体重測定装置を提供することにある。   The present invention has been made in view of such circumstances, and by reading the specific information including the weight of the incidental and automatically calculating the patient's true weight, the patient's true weight can be obtained smoothly. Another object of the present invention is to provide a weight measuring apparatus that can avoid mistakes in the presence / absence and type of an accessory by an operator.

In addition, the personal information can be transmitted (transmitted) wirelessly. Specifically, like the specific information transmitting unit 2, the personal information includes a so-called RFID (Radio Frequency Identification) tag in so-called ubiquitous technology. The personal information transmission unit 3 may be carried by the patient H, or may be fixed to a name plate or the like worn by the patient H.

一方、アンテナ４は、固有情報送信手段２又は個人情報送信手段３が所定寸法の範囲内に近づくと、それらから送信された固有情報や個人情報を受信し得るよう構成されており、付随物を伴った患者Ｈが重量測定手段１の測定台１ａに乗ると、その患者Ｈ及び付随物に配設された固有情報送信手段２又は個人情報送信手段３からの情報を受信し得るよう設定されている。   On the other hand, the antenna 4 is configured to receive the unique information and personal information transmitted from the specific information transmitting unit 2 or the personal information transmitting unit 3 when the specific information transmitting unit 2 or the personal information transmitting unit 3 approaches the range of the predetermined size. When the accompanying patient H gets on the measuring platform 1a of the weight measuring means 1, it is set so as to be able to receive information from the specific information transmitting means 2 or the personal information transmitting means 3 disposed on the patient H and the accompanying items. Yes.

即ち、アンテナ４は、測定台１ａ上の患者及びその患者が付随した付随物からの固有情報又は個人情報に限定して受信可能とされており、周囲の患者や付随物に配設された固有情報や個人情報を受信しないよう構成されているのである。特に、本実施形態においては、アンテナ４の背面側にフェライト１０が取り付けられているため、測定すべき患者Ｈ側（測定台１ａ上の患者側）への指向性が高められており、アンテナ４の背面側にあり測定対象でない患者や付随物の固有情報又は個人情報を受信してしまうのを回避可能とされている。   That is, the antenna 4 can be received only by the specific information or personal information from the patient on the measurement table 1a and the accompanying object attached to the patient, and the antenna 4 is arranged in the surrounding patient and the accompanying information. It is configured not to receive information or personal information. In particular, in the present embodiment, since the ferrite 10 is attached to the back side of the antenna 4, the directivity toward the patient H side to be measured (the patient side on the measurement table 1a) is enhanced. It is possible to avoid receiving specific information or personal information of a patient or an accessory that is not a measurement target on the back side of the device.

然るに、本実施形態の如くアンテナ４を重量測定手段１における手摺り１ｂ以外の部位に配設するよう構成してもよく、例えば測定台１ａの下面に配設して上方に指向させるようにすれば、フェライト等の磁性体を配設せず測定台１ａ上の患者Ｈ側への指向性を向上させ、測定対象でない周囲の患者や付随物の固有情報又は個人情報を受信してしまうのを回避することが可能とされる。   However, the antenna 4 may be arranged in a portion other than the handrail 1b in the weight measuring means 1 as in the present embodiment. For example, the antenna 4 may be arranged on the lower surface of the measuring table 1a and directed upward. For example, it is possible to improve the directivity to the patient H side on the measurement table 1a without providing a magnetic material such as ferrite, and to receive specific information or personal information of surrounding patients and associated items that are not to be measured. It is possible to avoid it.

認識手段５は、アンテナ４と電気的に接続されたコンピュータ９の演算部などから成るものであり、アンテナ４で読み取られた情報が固有情報か否か、或いは個人情報か否かを認識するとともに、固有情報であれば付随物の種類や重量等を認識し、個人情報であれば患者の氏名や体重の測定の際に患者が付随すると予測される付随物の種類等を認識可能とされたものである。   The recognizing means 5 comprises a calculation unit of a computer 9 electrically connected to the antenna 4 and recognizes whether the information read by the antenna 4 is unique information or personal information. In the case of specific information, it is possible to recognize the type and weight of incidentals, and in the case of personal information, it is possible to recognize the type of incidentals that the patient is expected to accompany when measuring the patient's name and weight. Is.

演算手段６は、認識手段５と同様、アンテナ４と電気的に接続されたコンピュータ９の演算部などから成り、重量測定手段１とも電気的に接続されたものであるとともに、重量測定手段１による測定値（患者Ｈと車椅子Ｋを含む付随物全ての総重量）からアンテナ４で読み取られた付随物の重量（車椅子Ｋを含む付随物全ての重量）を差し引いて、患者Ｈの真の体重を演算するためのものである。   Similar to the recognition means 5, the calculation means 6 includes a calculation unit of a computer 9 electrically connected to the antenna 4, and is also electrically connected to the weight measurement means 1. Subtract the weight of all appendages read by antenna 4 (the weight of all appendages including wheelchair K) from the measured value (total weight of all appendages including patient H and wheelchair K) to obtain the true weight of patient H It is for calculation.

即ち、アンテナ４にて固有情報及び個人情報が受信され、認識手段５にて患者Ｈや各付随物の重量が認識されるため、患者Ｈと患者が付随した各付随物の重量の合計が把握され、その合計を重量測定手段１にて測定された測定値から差し引く演算を行えば、患者Ｈの真の体重（付随物を全て取り除いた状態の体重）を求めることができるのである。従って、付随物の重量を含む固有情報を読み取って患者Ｈの真の体重を自動的に演算することができ、患者Ｈの真の体重をスムーズに求めることができるとともに、作業者による付随物の有無や種類の判断ミスを回避することができる。   That is, since the unique information and personal information are received by the antenna 4 and the weight of the patient H and each accessory is recognized by the recognition means 5, the total weight of the patient H and each accessory accompanying the patient is grasped. Then, if the calculation is performed by subtracting the total from the measurement value measured by the weight measuring means 1, the true weight of the patient H (the weight in a state where all the accompanying items are removed) can be obtained. Therefore, it is possible to automatically calculate the true body weight of the patient H by reading the unique information including the weight of the appendage, and to obtain the true weight of the patient H smoothly. It is possible to avoid mistakes in the presence / absence and type.

更に、本実施形態に係る体重測定装置は、固有情報送信手段２から送信されてアンテナ４にて読み取られた付随物の種類と、当該個人情報送信手段３から送信されてアンテナ４にて読み取られた付随物の種類（体重の測定の際に患者Ｈが付随すると予測される付随物の種類）とを比較し、両者が一致した場合に限り、演算手段６による演算を行わせるよう構成されている。これにより、固有情報の読み取りミスを防止し、より確実に患者の真の体重を求めることができ、体重測定装置の信頼性をより向上させることができる。   Furthermore, the weight measuring apparatus according to the present embodiment is the kind of the accessory transmitted from the unique information transmitting unit 2 and read by the antenna 4, and the accompanying information transmitted from the personal information transmitting unit 3 and read by the antenna 4. The type of the accessory (the type of the accessory that is expected to be accompanied by the patient H at the time of measuring the body weight) is compared, and the calculation by the calculation means 6 is performed only when the two match. Yes. Thereby, reading error of specific information can be prevented, the true weight of the patient can be obtained more reliably, and the reliability of the weight measuring apparatus can be further improved.

表示器７は、パソコン９のディスプレー等から成り、その画面には、図３に示すように、演算手段６による演算結果（患者の真の体重）が「透析前体重」の欄、付随物（風袋）の種類や重量が「風袋補正」の各欄、付随物（風袋）の合計重量が「風袋補正値」の欄、患者の個人情報が「名前」の欄等に表示されるようになっている。また、表示器７には、同図に示す如き他の情報（例えば、患者のドライウェイトや前回後体重、体重増減等）が表示される。   The display 7 is composed of a display of the personal computer 9, and as shown in FIG. 3, the calculation result (the true weight of the patient) by the calculation means 6 is displayed in the column “Body weight before dialysis” in the screen. (Tare) type and weight are displayed in each column of “Tare Correction”, the total weight of accompanying items (Tare) is displayed in the “Tare Correction Value” column, and the patient's personal information is displayed in the “Name” column, etc. ing. Further, the display 7 displays other information (for example, the patient's dry weight, the weight after the previous time, the weight increase / decrease, etc.) as shown in FIG.

送信手段８は、演算手段６で演算された患者Ｈの真の体重に加え、認識手段５にて認識された固有情報や個人情報など他の情報を、その患者Ｈに対して血液透析治療するための血液透析装置に送信するものである。従って、血液透析装置は、例えば他の治療室内に設置されて患者Ｈに対して血液透析治療を行うためのもので、送信手段８にて送信された患者の真の体重に基づき、例えば「患者の真の体重−ドライウェイト」なる演算により除水量を求め、その求められた除水量に基づき除水が行われるよう構成されている。これにより、除水量を精度よく求めて血液透析治療を確実に行わせることができる。
The transmitting means 8 hemodialyzes the patient H with other information such as specific information and personal information recognized by the recognition means 5 in addition to the true weight of the patient H calculated by the calculating means 6. Is sent to the hemodialysis machine. Accordingly, the hemodialysis apparatus is installed in another treatment room, for example, for performing hemodialysis treatment on the patient H. Based on the true body weight of the patient transmitted by the transmission means 8, for example, “patient The water removal amount is obtained by the calculation of “true weight-dry weight”, and water removal is performed based on the obtained water removal amount. Thereby, water removal amount can be calculated | required accurately and hemodialysis treatment can be performed reliably.

本実施形態によれば、固有情報送信手段２及び個人情報送信手段３は、アンテナ４へ情報を送信可能なＩＣタグから成るので、固有情報送信手段２及び個人情報送信手段３からの固有情報又は個人情報をより精度良く且つ非接触にてアンテナ４にて読み取らせることができるとともに、当該固有情報送信手段２及び個人情報送信手段３を付随物や患者の任意の部位に配設させることができる。また、付随物の重量を含む固有情報を非接触にて読み取って患者Ｈの真の体重を自動的に演算することができるので、接触して操作することがなく衛生的である。   According to this embodiment, the unique information transmitting means 2 and the personal information transmitting means 3 are composed of IC tags capable of transmitting information to the antenna 4, so that the unique information from the unique information transmitting means 2 and the personal information transmitting means 3 or The personal information can be read by the antenna 4 with higher accuracy and in a non-contact manner, and the specific information transmission means 2 and the personal information transmission means 3 can be disposed in an accompanying part or an arbitrary part of the patient. . In addition, since the specific weight information including the weight of the accessory can be read in a non-contact manner and the true weight of the patient H can be automatically calculated, it is hygienic without being touched and operated.

また、読み取り手段としてのアンテナ４は、固有情報送信手段２で送信された固有情報に加え、個人情報送信手段３で送信された個人情報を非接触にて読み取り可能とされたので、固有情報と個人情報とを関連付けさせることが容易に可能となり、患者の真の体重或いは除水量等の算出を個人情報を参照させつつ確実に行わせることができる。   In addition to the unique information transmitted by the unique information transmitting means 2, the antenna 4 as the reading means can read the personal information transmitted by the personal information transmitting means 3 in a non-contact manner. The personal information can be easily associated with each other, and the calculation of the patient's true weight or water removal amount can be performed with reference to the personal information.

以上、本実施形態について説明したが、本発明はこれに限定されず、例えば固有情報送信手段２には、配設される付随物の所有者が記録されるとともに、当該固有情報送信手段２から送信されてアンテナ４にて読み取られた所有者と、個人情報送信手段３から送信されてアンテナ４にて読み取られた個人情報の患者の氏名とを比較し、両者が一致した場合に限り、演算手段６による演算を行わせるよう構成してもよい。この場合、固有情報の読み取りミスを防止し、より確実に患者の真の体重を求めることができ、体重測定装置の信頼性をより向上させることができる。   Although the present embodiment has been described above, the present invention is not limited to this. For example, the unique information transmitting unit 2 records the owner of the associated accessory, and the unique information transmitting unit 2 The owner transmitted and read by the antenna 4 is compared with the patient's name of the personal information transmitted from the personal information transmitting means 3 and read by the antenna 4, and the calculation is performed only when the two match. You may comprise so that the calculation by the means 6 may be performed. In this case, the reading error of the unique information can be prevented, the true weight of the patient can be obtained more reliably, and the reliability of the weight measuring apparatus can be further improved.

また、アンテナ４は、固有情報又は個人情報の読み取りを一定時間で複数回行うとともに、当該複数回の読み取り全てで同一の固有情報又は個人情報が読み取られた場合に限り、演算手段６による演算を行わせるよう構成してもよい。この場合であっても、アンテナ４による複数回の読み取り全てで同一の固有情報又は個人情報が読み取られた場合に限り演算手段６による演算を行わせるので、単に近くを通り過ぎたような患者や付随物からの情報を排除することができ、固有情報の読み取りミスを更に確実に防止し、体重測定装置の信頼性をより向上させることができる。   The antenna 4 reads the unique information or the personal information a plurality of times in a fixed time, and performs the calculation by the calculation means 6 only when the same unique information or the personal information is read by all the multiple readings. You may comprise so that it may be performed. Even in this case, since the calculation by the calculation means 6 is performed only when the same unique information or personal information is read by a plurality of readings by the antenna 4, the patient or associated incidents that have just passed nearby. Information from the object can be eliminated, reading errors of the unique information can be more reliably prevented, and the reliability of the weight measuring apparatus can be further improved.

更に、アンテナ４による固有情報又は個人情報の読み取り後、所定時間、当該固有情報又は個人情報の読み取りを行わないよう構成してもよい。この場合、患者が体重測定装置で体重を測定する際、その前の患者が車椅子Ｋにて運搬されるまでの時間を考慮することができ、前に体重の測定を行った患者の固有情報又は個人情報に基づいて演算手段６による演算が行われてしまうのを回避することができる。   Furthermore, after reading the specific information or personal information by the antenna 4, the specific information or personal information may not be read for a predetermined time. In this case, when the patient measures the weight with the weight measuring device, the time until the previous patient is transported in the wheelchair K can be taken into account, and the specific information of the patient who has previously measured the weight or It is possible to avoid the calculation by the calculation means 6 based on the personal information.

また更に、重量測定手段１の測定台１ａ上の患者Ｈにおける付随物を作業者が確認し、表示器７で表示された付随物に誤りがある場合（例えば、測定台１ａ上の患者が杖を持っていない或いは義手や義足ではないのに、表示器７でそれらの表示がある場合等）、その付随物を選択して削除し得るよう構成してもよい。この場合、作業性に若干の悪影響があるものの、最終確認のみを作業者に行わせることができるので、固有情報の読み取りミスを防止し、より確実に患者の真の体重を求めることができ、体重測定装置の信頼性をより向上させることができる。
Still further, when an operator confirms an incidental item in the patient H on the measuring table 1a of the weight measuring means 1 and there is an error in the incidental item displayed on the display 7 (for example, the patient on the measuring table 1a is a cane In the case where the display device 7 does not have a hand or a prosthesis or a leg, but the display device 7 has such display), the accessory may be selected and deleted. In this case, although there is a slight adverse effect on workability, since only the final confirmation can be made to the worker, reading errors of unique information can be prevented, and the true weight of the patient can be obtained more reliably, The reliability of the weight measuring device can be further improved.

尚、固有情報送信手段２は、車椅子Ｋ、パジャマ、サンダル、杖、義手或いは義足の他、患者の身体以外のものであって当該患者と共に測定される如何なる付随物にも配設することができ、記録される情報は、当該付随物の種類や重量或いは所有者とは異なるものであってもよい。同様に、個人情報送信手段３に記録される情報は、患者の氏名や体重の測定の際に付随すると予測される付随物の種類の他、ドライウェイトや治療の履歴等であってもよい。   In addition, the specific information transmission means 2 can be disposed on any wheelchair K, pajamas, sandals, walking stick, prosthetic hand or prosthetic leg or any other accessory other than the patient's body and measured together with the patient. The information to be recorded may be different from the type and weight of the associated item or the owner. Similarly, the information recorded in the personal information transmitting means 3 may be a dry weight, a history of treatment, or the like in addition to the types of incidental substances that are predicted to accompany the measurement of the patient's name and weight.

また更に、アンテナ４を送受信可能なものとしつつ固有情報送信手段２及び個人情報送信手段３を受信可能なものとし、アンテナ４と固有情報送信手段２及び個人情報送信手段３との間で情報を送受信可能に構成してもよい。この場合、固有情報送信手段２及び個人情報送信手段３は、受信した情報により記録された情報を更新可能なよう構成するのが好ましい。   Further, the unique information transmitting means 2 and the personal information transmitting means 3 can be received while the antenna 4 can be transmitted and received, and information is transmitted between the antenna 4 and the specific information transmitting means 2 and the personal information transmitting means 3. You may comprise so that transmission / reception is possible. In this case, it is preferable that the unique information transmitting unit 2 and the personal information transmitting unit 3 are configured to be able to update the information recorded by the received information.

次に、本発明に係る第２の実施形態について説明する。
本実施形態に係る体重測定装置は、血液透析治療にかかる患者の体重を測定するためのものであり、図４に示すように、重量測定手段１と、車椅子Ｋに取り付けられた固有情報送信手段２と、患者Ｈに取り付けられた個人情報送信手段３と、読み取り手段としてのアンテナ４’と、パソコン９を構成する認識手段５、演算手段６及び表示器７と、送信手段８とから主に構成されている。尚、第１の実施形態と同様の構成要素には、同一の符号を付し、その詳細な説明を省略する。 Next, a second embodiment according to the present invention will be described.
The weight measuring apparatus according to the present embodiment is for measuring the weight of a patient involved in hemodialysis treatment. As shown in FIG. 4, the weight measuring means 1 and the unique information transmitting means attached to the wheelchair K are provided. 2, a personal information transmitting means 3 attached to the patient H, an antenna 4 ′ as a reading means, a recognizing means 5, a computing means 6 and a display 7 constituting the personal computer 9, and a transmitting means 8. It is configured. In addition, the same code | symbol is attached | subjected to the component similar to 1st Embodiment, and the detailed description is abbreviate | omitted.

アンテナ４’は、照射波を発し得るとともに、該照射波による固有情報送信手段２又は個人情報送信手段３からの固有情報又は個人情報を含む反射波を受信し得るものである。即ち、アンテナ４’から照射波が発せられており、この照射波が及ぼす範囲内に固有情報送信手段２や個人情報送信手段３が至ると、当該照射波が反射して生じる反射波に記録された固有情報や個人情報を乗せて送信し得るようになっているのである。
The antenna 4 ′ can emit an irradiation wave and can receive a reflected wave including specific information or personal information from the specific information transmission unit 2 or the personal information transmission unit 3 by the irradiation wave. That is, an irradiation wave is emitted from the antenna 4 ′, and when the unique information transmission means 2 or the personal information transmission means 3 reaches within the range affected by the irradiation wave, the irradiation wave is reflected and recorded in the reflected wave. It is possible to send unique information and personal information.

これにより、当該反射波をアンテナ４’が受信すると、固有情報送信手段２や個人情報送信手段３に記録された固有情報や個人情報を読み取ることができ、読み取られた情報が認識手段５に送信されて、アンテナ４’で読み取られた情報が固有情報か否か、或いは個人情報か否かを認識するとともに、固有情報であれば付随物の種類や重量等を認識し、個人情報であれば患者の氏名や体重の測定の際に患者が付随すると予測される付随物の種類等を認識可能とされている。   Thus, when the reflected wave is received by the antenna 4 ′, the unique information and the personal information recorded in the unique information transmitting unit 2 and the personal information transmitting unit 3 can be read, and the read information is transmitted to the recognizing unit 5. In addition, it recognizes whether the information read by the antenna 4 ′ is unique information or personal information, and if it is unique information, recognizes the type and weight of the incidental object, and if it is personal information. It is possible to recognize the type of an accessory that the patient is expected to accompany when measuring the patient's name and weight.

その後、演算手段６により、重量測定手段１による測定値（患者Ｈと車椅子Ｋを含む付随物全ての総重量）からアンテナ４’で読み取られた付随物の重量（車椅子Ｋを含む付随物全ての重量）を差し引き、患者Ｈの真の体重を演算する。従って、付随物の重量を含む固有情報を読み取って患者Ｈの真の体重を自動的に演算することができ、患者Ｈの真の体重をスムーズに求めることができるとともに、作業者による付随物の有無や種類の判断ミスを回避することができる。   Thereafter, the weight of the accessory (including all the accessories including the wheelchair K) read by the antenna 4 ′ from the measurement value (the total weight of all the accessories including the patient H and the wheelchair K) by the weight measuring unit 1 is calculated by the calculating unit 6. Weight) is subtracted and the true weight of patient H is calculated. Therefore, it is possible to automatically calculate the true body weight of the patient H by reading the unique information including the weight of the appendage, and to obtain the true weight of the patient H smoothly. It is possible to avoid mistakes in the presence / absence and type.

更に、演算手段６による演算結果（患者の真の体重）が、表示器７の画面における、「透析前体重」の欄、付随物（風袋）の種類や重量が「風袋補正」の各欄、付随物（風袋）の合計重量が「風袋補正値」の欄、患者の個人情報が「名前」の欄等に表示されるようになっている。また、表示器７には、第１の実施形態と同様、同図に示す如き他の情報（例えば、患者のドライウェイトや前回後体重、体重増減等）が表示される。   Further, the calculation result (the true weight of the patient) by the calculation means 6 is displayed in the column of “weight before dialysis” on the screen of the display unit 7, and in each column of the type and weight of the accessory (tare correction), The total weight of the accessory (tare) is displayed in the “Tare Correction Value” column, the patient's personal information is displayed in the “Name” column, and the like. Similarly to the first embodiment, the display 7 displays other information (for example, the patient's dry weight, the weight after the previous time, the weight increase / decrease, etc.) as shown in FIG.

また更に、第１の実施形態と同様、送信手段８により、演算手段６で演算された患者Ｈの真の体重に加え、認識手段５にて認識された固有情報や個人情報など他の情報が、その患者Ｈに対して血液透析治療するための血液透析装置に送信されるよう構成されている。これにより、送信手段８にて送信された患者の真の体重に基づき、例えば「患者の真の体重−ドライウェイト」なる演算により除水量を求め、その求められた除水量に基づき除水が行われるので、除水量を精度よく求めて血液透析治療を確実に行わせることができる。
Furthermore, as in the first embodiment, in addition to the true weight of the patient H calculated by the calculation means 6 by the transmission means 8, other information such as unique information and personal information recognized by the recognition means 5 is also received. The patient H is transmitted to a hemodialysis apparatus for hemodialysis treatment. Thereby, based on the patient's true body weight transmitted by the transmission means 8, for example, a water removal amount is obtained by the calculation of "patient's true body weight-dry weight", and water removal is performed based on the obtained water removal amount. Therefore, it is possible to obtain the amount of water removal accurately and to ensure hemodialysis treatment.

本実施形態によれば、読み取り手段が、照射波を発し得るとともに、該照射波による固有情報送信手段２又は個人情報送信手段３からの固有情報又は個人情報を含む反射波を受信し得るアンテナ４’を具備するので、固有情報送信手段２又は個人情報送信手段３の情報の送信のための電力供給を不要とすることができる。即ち、第１の実施形態においては、固有情報送信手段２及び個人情報送信手段３が自ら情報を発信して当該情報を読み取り手段側に送信するものであるため、送信のための電池等を必要とするのに対し、本実施形態においては、固有情報又は個人情報を含んだ反射波にて当該情報を読み取り手段側に送信するので、電池等が不要となるのである。   According to the present embodiment, the reading unit can emit an irradiation wave, and can receive a reflected wave including specific information or personal information from the specific information transmission unit 2 or the personal information transmission unit 3 by the irradiation wave. Therefore, it is possible to eliminate the need for power supply for transmission of information by the unique information transmission unit 2 or the personal information transmission unit 3. That is, in the first embodiment, since the unique information transmitting unit 2 and the personal information transmitting unit 3 transmit information themselves and transmit the information to the reading unit side, a battery for transmission is required. On the other hand, in the present embodiment, since the information is transmitted to the reading means side by a reflected wave including unique information or personal information, a battery or the like is not necessary.

患者及び患者の身体以外のものであって当該患者と共に測定される付随物の重量を測定するための重量測定手段と、付随物に配設され、当該付随物の重量を含む固有情報が記録されるとともに当該固有情報を無線にて送信し得る固有情報送信手段と、該固有情報送信手段で送信された固有情報を非接触にて読み取り可能な読み取り手段と、記重量測定手段による測定値から前記読み取り手段で読み取られた付随物の重量を差し引いて、患者の真の体重を演算する演算手段と、血液透析治療にかかる患者に取り付けられ、その患者固有の個人情報が記録されるとともに当該個人情報を無線にて送信し得る個人情報送信手段とを具備するとともに、読み取り手段は、固有情報送信手段で送信された固有情報に加え、個人情報送信手段で送信された個人情報を非接触にて読み取り可能とされ、かつ、個人情報送信手段には、体重の測定の際に患者が付随すると予測される付随物の種類が記録されるとともに、固有情報送信手段から送信されて読み取り手段にて読み取られた付随物の種類と、当該個人情報送信手段から送信されて読み取り手段にて読み取られた付随物の種類とを比較し、両者が一致した場合に限り、演算手段による演算を行わせる体重測定装置であれば、他の機能が付加されたもの等にも適用することができる。
