Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an auxiliary bladder device set.

[0002]

[Prior art]

 In patients with spinal cord injury, cerebral hemorrhage and encephalomalacia, postoperative patients, bedridden elderly, etc., urination is often difficult and symptoms such as urinary incontinence are often associated. In such cases, urinary tract management was mainly performed by the continuous urinary method using an indwelling urinary catheter. It has been clarified that this method has various problems, and as a solution to these problems, an auxiliary bladder device set has been proposed (Japanese Patent Laid-Open No. 60-171047, Japanese Patent Laid-Open No. 17-1047). 60-176661).

These auxiliary bladder device sets have a function of intermittently urinating urine accumulated in the bladder by utilizing the principle of siphon. In addition, in order to urinate the urine without leaving any urine in the bladder when urinating, a pressure regulation chamber holding a ventilation resistance filter is provided. By using such an auxiliary bladder device set, the bladder will be repeatedly filled and discharged with urine at regular intervals, making it possible to maintain the body's original urinary function. In addition, the self-cleaning action and infection defense function are also expressed, and it has become possible to reduce the occurrence of urinary tract infection due to bacteria.

[Problems to be solved by the device]

 However, when these auxiliary bladder device sets are used in a medical facility such as a hospital, the patient is bound to the bed. In particular, patients with cerebrovascular accidents and spinal cord injuries who are the targets of the auxiliary bladder device set will undergo various trainings to return to society, but at this time, remove the device and keep the removed part clean. It had the drawback of being difficult.

It is an object of the present invention to solve the above problems and provide an auxiliary bladder device set which can be used by patients and medical staff with peace of mind.

[0006]

[Means for Solving the Problems]

 As a result of intensive studies to achieve the above object, the present inventors have provided a detachable connector of the same size when connecting the device to the connecting tube and urine storage device in the above-mentioned auxiliary bladder device set. As a result, they have found that the above problems can be solved and arrived at the present invention.

That is, the present invention is an auxiliary bladder device that intermittently discharges urine by the action of a siphon tube. The gist is an auxiliary bladder device set characterized by being connected by a detachable connector of a size.

Hereinafter, the present invention will be described in detail. The auxiliary bladder device set that intermittently discharges urine by the action of the siphon applies the siphon principle, and therefore does not require a mechanical or electrical drive and control device for urine storage and urination, and can be operated at any interval. It is a device that allows urination after leaving. For example, there is an auxiliary bladder device installed via a micturition tube to a urinary catheter placed in the bladder and a device in which a urine storage device is connected below the auxiliary bladder device. Examples include character-shaped and concentric shaft type siphon tubes. As an example using an inverted U-shaped siphon tube, the device described in JP-A-60-171047, and as an example using a concentric shaft type siphon tube, JP-A-60-176661. An example is the device described in the publication.

Such an auxiliary bladder device is used by being connected to a urinary catheter discharge end via a connecting tube and a urine storage device via another connecting tube. The auxiliary bladder device of the present invention is connected to the discharge end of the urine catheter by a connecting tube having one set of detachable connectors, and further, a urine reservoir via another connecting tube having one set of detachable connectors of the same size. Connected to.

As a material for forming the main body of the auxiliary bladder device, for example, hard plastic is used, but the hard plastic is not particularly limited as long as it can be injection-molded. Preferably, polycarbonate, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate, polystyrene, polyarylate, acrylic resin or the like is used.

The material of the detachable connector in the present invention is not particularly limited as long as it is a thermoplastic resin. However, it is desirable that the inner diameter of the connector is 3 mm or more, preferably 5 mm or more.

The urine storage device according to the present invention may be a tank, a plastic bag, a bottle or the like, but a urine storage device capable of maintaining a closed system is preferably used.

The connecting tube is not particularly limited as long as it is a flexible material.

A specific example of the present invention will be described with reference to the drawings. Figure 1 shows an auxiliary bladder device set in which a removable connector is provided on the connecting tube that connects the auxiliary bladder device and the urinary catheter, and a removable connector of the same size is provided on another connecting tube that connects to the urine storage device. Is shown. In FIG. 1, a urinary catheter 2 placed in a bladder 1 is connected to a pressure adjusting chamber 5 of an auxiliary bladder device by a connecting tube 3 having a removable female connector 15 and a connecting tube 4 having a male connector 16. It is connected at the bottom. The pressure adjusting chamber 5 contains a concentric shaft type siphon pipe, and the concentric shaft type siphon pipe is composed of an outer pipe 6 and an inner pipe 7. Further, in the pressure adjusting chamber 5, a ventilation port 8 is formed at a position higher than the highest position of the concentric shaft type siphon tube, and the ventilation port 8 is provided with a ventilation resistance filter 9 for sealing the ventilation port 8. There is. The inner tube 7 projects below the pressure adjusting chamber 5, is connected by a flexible tube 10 to a tube 11 having the same inner diameter as the inner tube 7, and further has a connecting tube having a removable female connector 17. The tube 11 and the urine reservoir 14 are connected via a connecting tube 13 having a male connector 12 and a male connector 18.

FIG. 2 shows a state in which the urinary catheter and the urine storage device are connected and the patient leaves the bed to perform training. In FIG. 2, the connecting tube 3 and the connecting tube 13 are connected by a female connector 15 and a male connector 18, and a urine reservoir 14 is carried by a patient. FIG. 3 shows a state in which the two connecting tubes of the auxiliary bladder device are connected and the storage state of the auxiliary bladder device when the patient leaves the bed. In FIG. 3, the connecting tube 4 and the connecting tube 12 are connected by the male connector 16 and the female connector 17, and the auxiliary bladder device is kept closed and stored.

The auxiliary bladder device set of the present invention is used in patients with spinal cord injury, cerebral hemorrhage, encephalomalacia, post-operative patients, bedridden elderly people who have difficulty urinating, and patients who have urinary incontinence symptoms. be able to.

[0017]

[Work]

 In the auxiliary bladder device set of the present invention, the urinary catheter, the urine storage device, and the auxiliary bladder device can be respectively attached and detached by the detachable connector, so that the patient can easily detach from the auxiliary bladder device by detaching the detachable connector. However, the detached connector can be connected directly to the urine storage device, allowing free movement. In addition, since the inlet and outlet of the removed auxiliary bladder device can be joined with a detachable connector, a closed system can be maintained, external contamination can be prevented, and the route of infection can be cut off.

[0018]

[Effect of device]

 The auxiliary bladder device set of the present invention can easily remove the auxiliary bladder device main body from the patient, can expand the range of action of the patient, and keep the closed system when the auxiliary bladder device main body is removed. It can prevent external contamination and cut off the route of infection.
