Regarding tools. Further, the present invention relates to parts used in this protective equipment and a blood pump system using this protective equipment.

[0002]

2. Description of the Related Art Conventionally, various treatments have been performed using medical devices such as tubes embedded in a living body. For example, the use of artificial heart during and after heart surgery,
Examples include artificial dialysis and peritoneal dialysis. In these treatments, an infectious disease in a portion where a tube or the like penetrates the skin (hereinafter referred to as a “tube or the like penetrating portion”) has become a clinically serious problem. This is because the bonding force between the surface of the tube or the like and the living tissue in the vicinity of the skin is weak in the penetrating portion of the tube or the like, so that external force easily causes peeling between the surface of the tube or the like and the living tissue, and bacteria from that part Because it invades the skin tissue and causes an infection. Once an infectious disease occurs in the penetrating portion of the tube or the like, the infection deeply propagates into the living tissue along the tube or the like, increasing the risk of causing serious complications such as sepsis.

Therefore, the present applicant has developed a fixing tool for solving this problem and has already applied for a patent (see Japanese Patent Laid-Open No. 2000-140125). FIG. 16 is a sectional view of this fixture. As shown in FIG. 16, this fixture 910 is a fixture for protecting a tube penetration part where a tube 990 penetrates the skin of a living body from infection, and is fixed to the skin 902 of the living body around the tube penetration part. A sticking part 920 to be stuck, and a covering part 980 for covering the tube penetrating part to form an internal space 908 surrounding the tube penetrating part and passing the tube 990 therethrough.
And a covering portion 940 having.

Therefore, according to this fixing tool 910, the tube penetrating the skin of the living body can be made difficult to move, so that the separation of the tube and the living tissue due to the external force is suppressed, and as a result, the occurrence of infectious diseases is effective. Can be prevented. Further, according to this fixing tool 910, since the medicine can be filled in the internal space 908 surrounding the tube penetrating portion, it is possible to more effectively prevent the occurrence of infection.

[0005]

However, an infection at the penetrating portion of a tube or the like may cause a serious complication such as sepsis due to the extent of the infection deeply spreading / extending in the living tissue along the tube or the like. Therefore, it is required to further suppress the occurrence of this infectious disease.

The object of the present invention is to provide a protective device capable of further suppressing the occurrence of this infectious disease.

The pump unit 110 has a pump blade 118 that is driven via a rotating shaft of a motor, and a casing 116 that is connected to the pump base so as to cover the pump blade 118. Inflow port 112 provided at the end point of casing 116
Blood in the left ventricle A flows into the casing from the inside of the casing, and after energy is added by the pump blades 118 in the casing, the blood is discharged to the aorta B through the outlet 114 provided on the side surface of the casing and the artificial blood vessel C. .

An end surface contact type blood seal (hereinafter, also referred to as “mechanical seal”) is provided between the pump base 120 and the pump blade 118, and a bearing of the motor rotating shaft due to infiltration of blood components is provided. Prevents adhesion. In addition, the pump base 120 has an inlet 132 for circulating liquid.
And an outlet 134 (which is difficult to understand from FIG. 5, the inlet 132 and the outlet 134 are provided separately in the direction perpendicular to the paper surface), and the inlet 1 for these circulating liquids is provided.
The outlet 32 and the outlet 134 are connected to the controller 200 via an inner tube 302 (see FIG. 6) housed in the tube 300. A circulating fluid pump is provided in the controller 200, and the circulating fluid pump circulates the circulating fluid to the vicinity of the mechanical seal. As a result, the sliding surface of the mechanical seal is lubricated, cooled and diffused, and the filter provided in the controller 200 removes a trace amount of blood components that may enter into the circulating fluid, thereby providing a mechanical seal. And the sliding surface of the bearing is always kept clean.
The blood pump 100 includes a centrifugal pump, an axial flow pump,
A mixed flow pump or the like can be preferably used. The blood seal is not limited to the mechanical seal, and other contact type seals such as an oil seal can be used.

Further, the external controller 200 is a circulating fluid pump for supplying the circulating fluid to the vicinity of the mechanical seal of the blood pump 100, and the cable 3 accommodated in the tube 300.
A pump control section for electrically controlling the driving of the blood pump 100 via 04, a display section for displaying the operating state and data of each of these means, a communication section for exchanging information with the outside, and supplying power to each of these means. It has a system drive unit including an electric power supply unit for controlling the power supply and a control unit for controlling the respective units, and these units are housed in a compact housing.

In this example, the external controller 200 is in the form of a wheelbarrow, but in addition, it may be in the form of a wheelchair or a bag, which is suitable for the patient's condition and living environment. Things are used. further,
An electric movement type controller in which motors are added to wheels is also used.

FIG. 6 shows the blood pump system 500 of FIG.
It is a figure for demonstrating the tube 300 used for. As shown in FIG. 6, the tube 300 according to the third embodiment includes a blood pump 100 and the blood pump 1.

Is hard to break. Also,
In the tube 300 according to the third embodiment, the living body can be penetrated only at one place (tube penetrating portion), so that the influence on the living body can be minimized.

The tube 300 according to the third embodiment is
It has two inner tubes 302, and by using these two inner tubes, pure water is circulated between the blood pump 100 and the external controller 200. The pure water functions as a coolant for the motor part of the blood pump, a lubricant for the blood seal sliding part, and a sealant between the blood pump part and the motor part. Furthermore, by circulating pure water between the blood pump and the controller, even if blood enters, the rotation of the motor is stopped because the blood is diluted with pure water and coagulation of blood is suppressed. It can be effectively prevented. Further, since blood components can be removed by filtering pure water, it is possible to more effectively prevent the rotation of the motor from stopping. Furthermore, by circulating pure water, there is an effect that heat in the blood pump can be dissipated.
