Non-sticking nasogastric probe

FIELD: medical engineering.

SUBSTANCE: device has silicon single-lumen tube as base. Device wall has longitudinal cuts near the olive at the same level. The cuts divide non-sticking nasogastric probe circumference into four equal sections. Capillary polypropylene tube for introducing solutions easily passes through the lumen. The tube has needle at the level of sections. It is attached to the non-sticking nasogastric probe olive with one end. Free end of the capillary tube movably passes through the non-sticking nasogastric probe wall from inside to outside 8-10 cm far from free end edge.

The present invention relates to medical equipment, namely, drains, and can be used in hospitals, particularly in surgical hospitals.

Known nasogastric (stomach) probe - NGZ (Figure 1).

The disadvantage of this probe is the failure to provide adequate drainage of the stomach due to Dneprospetsstal main tube and sticking to the walls of the stomach to the drain holes of the probe, thereby preserved adrenium of the stomach cavity and remains gastritis.

The closest in technical essence and the achieved result is a device for irrigation of drug substance hollow organs (copyright certificate №1651912, class a 61 M 1/00, 1988) (Figure 2), consisting of outer and inner tubes with injection and suction systems and fixed to the tubes perforated hollow tip, communicated with the inner tube. The tip is made in the form of a hemisphere with a radius equal to the radius of the outer tube, the surface of which is a hole with a diameter decreasing toward the outside of the end.

However, the known device is in direct contact with a limited area of the gastric mucosa, the corresponding surface of the probe, and does not allow the jets of the gastric mucosa irrigated solutions introduced into the probe, while the Pro is Ivanyi stomach.

The purpose of the invention is the increased functionality of the refinery by increasing the area of the contact surface of the gastric mucosa with the drained cavity created by the probe, and providing opportunities for improving blood circulation in the stomach in the whirlpool of the gastric mucosa with the introduction of fluids into the probe, thereby reducing the period of postoperative gastroschisis.

The essence of the proposal is that depressives nasogastric tube (NGS) contains a base of silicone odnoprovodnoi tube wall NGS near olive has a longitudinal incisions on one level, dividing the circumference NGS equals 4 sections. In the lumen NGS passes freely polypropylene capillary tube for intravenous injections with needle holes at the level of sections, one end of which is fixed to the olive NNGS, the free end of the capillary tube movably passes through the wall of NGS from the inside outwards 8-10 cm to the edge of the free end.

Figure 3 shows a General view NNGS, figure 4 is a view in the folded position, figure 5 - view from spherically bent sections (working status).

Depressives nasogastric tube (NHS) consists of a base 1 made of silicon odnoprovodnoi tube, the lumen of which passes freely polypropylene capillary tube 2 for the introduction of solutions, one is oncom fixed to Oliva NGS-3. Wall NGS near olive has a longitudinal incision length up to 10 cm on one level, dividing the circumference NGS equals 4 section 4. When pulling the capillary tube 2 in the lumen NGS is bending sections 4 out and approximation olive 3 to presechenii part NGS. When the bending section form field, separating the walls of the gastric mucosa from the capillary tube with holes 5, through which the irrigation mucosa. The spherical shape of the sections allows to increase the surface area of the gastric mucosa, available irrigation, and to create conditions of acceleration irrigated jets for hydromassage mucous.

Depressives nasogastric tube (NGS) is used as follows.

Pre make a statement NGS through the lower nasal passage into the stomach. Further, tightening capillary tube 2 at the free end 6 of a relatively free end NGS 7 in the cavity of the stomach is the bending sections 4 to spherical shape (working condition). When introduced into the capillary tube 2 solution for irrigation through hole 5 is spraying the solution on the walls of the gastric mucosa. At the same time it is possible to aspirirovanna fluid out of the stomach cavity through the lumen of the free end NGS-7.

The use of the present invention allows to extend the functionality of nasogastric tubes and the use in the treatment of postoperative gastroschisis, erosive, stasavage gastritis prophylaxis of bleeding method of massage of the gastric mucosa.

Depressives nasogastric tube contains a base of silicone odnoprovodnoi tube, characterized in that the wall depressives nasogastric tubes near olive has a longitudinal incisions on one level, dividing the circumference depressives nasogastric tubes to equal 4 sections, the lumen passes freely polypropylene capillary tube for the introduction of solutions having needle holes at the level of sections, one end of which is fixed to the olive depressives nasogastric probe, the free end of the capillary tube movably passes through the wall of depressives nasogastric tubes from the inside outwards 8-10 cm to the edge of the free end.

SUBSTANCE: one should perform puncturing of epidural space at Th12-L1 level. Through the lumen of puncture needle one should introduce catheter to move it cranially at the depth of 3 cm. After that one should inject 10 ml 05%-marcaine solution to perform repeated injections per 5.0 ml every 4 h during 1-8 d. The effect is achieved due to unloading minor cycle of circulation.

EFFECT: higher efficiency of therapy.

SUBSTANCE: method involves clipping aneurysms and setting two catheters into chiasmatic cistern and into internal carotid artery cistern. After having finished the operation, liquor is discharged concurrently from chiasmatic cistern and internal carotid artery cisterns in the amount of 5-7 ml at a rate of 30-40 ml/h. Two F90PvB Portex filters are sequentially attached to each catheter and the collected liquor is introduced at a rate of 30-40 ml/h and filtered. The cycle is repeated until one volume of circulating liquor is filtered. The process is repeated 6 h later in taking one filter off from each catheter and liquor filtration is continued through one filter. The liquor filtration sessions are repeated every other day depending on subarachnoid hemorrhage intensity. Total liquor filtration treatment is not to last more than 96 h long.
