【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【発明の属する技術分野】本発明は腹膜透析装置に関する。 The present invention relates to relates to a peritoneal dialysis machine. より詳しくは、腹腔内に過度の圧力がかかることがなく、吐出圧が一定で実質的に脈流を生ずることのない腹膜透析装置に関する。 More particularly, without consuming excessive pressure in the abdominal cavity, to a peritoneal dialysis device without the discharge pressure occurs substantially ripple constant.

【0002】 [0002]

【従来の技術】腎不全患者の治療には、従来、人工透析療法や腹膜透析療法が採用されている。 The treatment of the Prior Art renal failure patients, conventional, artificial dialysis and peritoneal dialysis therapy is employed. 人工透析療法は通常週に約3回の通院が必要であり、患者に時間的な拘束を強いるため、患者の社会復帰の大きな妨げになっている。 Dialysis therapy is necessary is about 3 times of visits to a normal week, to force a time restraint on patients, it has become a major obstacle to social rehabilitation of patients. 一方、腹膜透析療法は、患者の腹膜を利用して透析を行う方法であり、治療に一日4回の透析液の交換が必要であるが、在宅での治療に適しており、社会復帰が可能であることから近年注目されつつある。 On the other hand, peritoneal dialysis is a method for performing dialysis utilizes the patient's peritoneal, but replacing the 4 times a day for dialysate treatment is required, suitable for the treatment at home, the reintegration possible is attracting attention in recent years because it is.

【0003】腹膜透析療法には、昼間に患者自身が透析液の交換を行うCAPD(Continu-ous Ambulatory Per [0003] In peritoneal dialysis therapy, CAPD the patient himself in the daytime is the replacement of the dialysate (Continu-ous Ambulatory Per
itoneal Dialysis)と、自動腹膜透析装置を利用して自動で透析液の交換を行うAPD(Automated Peritoneal And itoneal Dialysis), APD that by using the automated peritoneal dialysis apparatus for performing the exchange of automatic in the dialysate (Automated Peritoneal
Dialysis )とがある。 Dialysis) and there is. CAPDは透析液の交換を患者自身が行うため、バッグの接続やバルブの切り替え等煩雑な操作が必要である。 CAPD is for performing the patient's own exchange of dialysate, it is necessary connections and switching such a complicated operation of the valve of the bag. 一方、APDは透析液交換作業の手間が省ける上、患者の腹腔カテーテルにおける接続回数がCAPDに比較して少なくなるため、細菌の混入による腹膜炎の発生する危険を減少させることができる。 Meanwhile, APD is on labor of dialysate replacement can be omitted, since the number of connections in the peritoneal catheter of a patient is reduced as compared to CAPD, can reduce the risk of occurrence of peritonitis caused by bacterial contamination. APDの中でも、夜間就寝中に透析液を交換するが昼間は透析液の交換をせずに貯液のままでいるCCPD Among the APD, but to replace the dialysate during the night in bed during the day remain of the reservoir without the exchange of the dialysate CCPD
(Continuous Cyclic Peritoneal Dialysis )、および夜間就寝中に透析液を交換し昼間は貯液しないNPD (Continuous Cyclic Peritoneal Dialysis), and during the day the change of dialysis solution during the night in bed not liquid storage NPD
(Nightly Peritoneal Dialysis)は、昼間の透析液交換が不要であるため社会復帰に適している。 (Nightly Peritoneal Dialysis) is, during the day of the dialysis fluid exchange is suitable for rehabilitation because it is unnecessary.

【0004】APDに使用する自動腹膜透析装置の場合、患者の腹腔内への透析液の注液および患者の腹腔内からの透析液の排液には、従来、落差圧を利用した落差式のものが採用されているが、この落差式のものは、落差を確保する必要があるため装置が大型になり、また排液の落差を確保するためにベッドの使用が強制されていた。 In the case of automated peritoneal dialysis apparatus used in APD, the drainage of the dialysate from the peritoneal cavity liquid injection and patient dialysate into the peritoneal cavity of the patient, conventionally in the fall centrifugal utilizing difference pressure what it is adopted, those of the drop-type apparatus it is necessary to secure the drop becomes large, also the use of the bed in order to ensure a drop of effluent has been forced. このような欠点を解消するものとして、近年、患者の腹腔内への透析液の注液および患者の腹腔内からの透析液の排出にローラーポンプを用いる方法が採用されているが、ローラーポンプには、腹腔カテーテルが閉塞している場合であっても透析液を強制的に供給してしまうという欠点があり、その結果、回路内圧が急激に上昇して回路を破損する虞があった。 As for eliminating the aforementioned disadvantages, in recent years, although liquid injection and a method using a roller pump to discharge the dialysate from the peritoneal cavity of the patient in the dialysate into the peritoneal cavity of the patient is employed, the roller pump , there is disadvantage that even when the abdominal catheter is obstructed thereby forcibly supplying dialysate, as a result, there is a risk of damaging the circuit circuit pressure rises sharply. また、透析液を腹腔内から排液する際にローラーポンプを用いると、腹腔内に透析液が残っていない場合にも強制的に吸引し、患者の腹腔に過剰な陰圧を加える虞があった。 Moreover, the use of a roller pump when draining dialysis fluid from the peritoneal cavity, even forcibly sucked when no remaining dialysate into the abdominal cavity, there is a possibility to add an excess of negative pressure to the patient's peritoneal cavity It was.

【0005】そこで、この問題を解決する方法として、 [0005] Therefore, as a method to solve this problem,
圧力検出手段により検出された腹腔内圧力に基づきポンプを制御する方法が提案されている(実公平3−403 Method of controlling the pump based on the detected intraperitoneal pressure has been proposed by the pressure detecting means (actual fair 3-403
03号公報)。 03 JP). このものは、透析液の移送を患者の腹腔内圧力を監視しながら行うため安全性が高いという利点を有するが、ローラーポンプを利用しているため、脈流が発生し、患者の腹腔に刺激を与えるという欠点があり、また、透析治療中に腹腔カテーテルの位置がずれる虞があった。 This thing is, the transfer of the dialysate has the advantage of high safety for performing while monitoring an intraperitoneal pressure of the patient, because it utilizes a roller pump, a pulsating flow occurs, stimulation to the patient's peritoneal cavity has the disadvantage of giving, also, the position of the peritoneal catheter there is a possibility that shift during dialysis treatment.

【0006】一方、落差の確保を必要としない方法として、従来、透析液用バッグを密閉硬質容器内に収納し、 On the other hand, as a method which does not require securing drop, conventionally, accommodating the bag dialysate in a closed rigid container,
透析液用バッグの雰囲気を加圧、減圧することで透析液を移送する方法や、軟質膜が張られた一対のチャンバーを交互に加圧、減圧することにより透析液を移送する方式が知られているが、前者の方法では、1回分の腹腔内貯留液量を腹腔内へ一度に供給または腹腔内から一度に排液する必要があるため、腹腔内貯留液量が多い場合に、透析液用バッグを収容するための密閉硬質容器も大きくなり、装置が大型になるという欠点を有していた。 Pressurized atmosphere of the dialysate bag, or a method of transferring dialysate by vacuum pressure the pair of chambers soft film is stretched alternately, a method of transferring the dialysis fluid by reducing the pressure is known and that, but if the former method, since it is necessary to drain batch of intraperitoneal effusion amount at a time from the supply or intraperitoneally at a time into the peritoneal cavity, often intraperitoneal reservoir fluid volume, the dialysate becomes large sealed rigid container for housing the use bags, it had the disadvantage that the apparatus becomes large.
また、後者の方法では、チャンバーの加圧、減圧時の切り換え時に、これに連動してバルブを切り換える必要があり、その際に騒音が発生するという欠点があった。 In the latter method, the pressure of the chamber, when switching under decompression, it is necessary to switch the valve in conjunction with this, the noise is disadvantageously generated at that time.

【0007】 [0007]

【発明が解決しようとする課題】本発明は如上の事情に鑑みてなされたもので、患者の腹腔に過剰な圧力を加えることがなく、患者の腹腔に刺激を与える脈流の圧力変動幅を小さくすることができ、小型で騒音の発生の少ない腹膜透析装置を提供することを目的とする。 [0008] The present invention has been made in view of the circumstances According to the process 30, without applying excessive pressure to the patient's abdominal cavity, the pressure fluctuation range of the pulsating flow to stimulate the patient's peritoneal cavity It can be reduced, and an object thereof is to provide a generating less peritoneal dialysis apparatus of the noise small.

【課題を解決するための手段】本発明は上記の課題を解決するために鋭意検討の結果、ポンプと並列に腹腔内に移送される透析液をバイパスする回路を設け、腹腔内の圧力が所定の圧力を超えたときに、透析液がバイパス回路でバイパスされる様にすればよいことに想到し、本発明を完成した。 The present invention SUMMARY OF] As a result of intensive studies in order to solve the above problems, a circuit for bypassing the dialysate is transferred into the abdominal cavity in parallel with the pump provided, the pressure in the abdominal cavity is predetermined when it exceeds the pressure of the dialysate is conceived that it is sufficient as to be bypassed by the bypass circuit, thereby completing the present invention. すなわち、本発明は、少なくとも2つの異なる組成の透析液を複数の透析液容器から混合容器に供給して混合し加温した後、該加温された透析液を腹腔内に移送し、使用済み透析液を排液するようにした腹膜透析装置において、透析液の混合容器への供給および腹腔内への移送、使用済み透析液の排液が1つの正逆転可能なローラーポンプで行われるとともに、該ローラーポンプと並列に設けられたバイパス回路により、腹腔の内圧が所定の圧力を超えたときに腹腔内に移送される透析液の一部がバイパスされるようにしてなる腹膜透析装置。 That is, the present invention may transfer After warming mixed is supplied to a mixing vessel dialysate of at least two different compositions from a plurality of dialysate containers, the the pressurized hot dialysate into the peritoneal cavity, spent in peritoneal dialysis apparatus in which the dialysate to drain, supply and transfer into the peritoneal cavity to the mixing vessel of the dialysis liquid, for the drainage of the spent dialysate is conducted in one a reversible roller pump, the bypass circuit provided in parallel with the roller pump, peritoneal dialysis apparatus in which a part of the dialysate is transferred into the abdominal cavity is so as to be bypassed when the internal pressure of the abdominal cavity exceeds a predetermined pressure. ここでバイパス回路には腹腔内の圧力が所定の圧力を超えたときに開く圧力制御弁を設けるのが好ましい。 Here the bypass circuit preferably provided with a pressure control valve that opens when the pressure in the abdominal cavity exceeds a predetermined pressure.
