Description

Simple negative pressure anal canal drainage device

Technical Field

The utility model belongs to the technical field of the anal canal drainage, concretely relates to simple and easy negative pressure anal canal drainage device.

Background

Fecal incontinence is a phenomenon frequently occurring in patients with intestinal surgery, coma, poisoning or paraplegia and the like, the stool is usually thin or even water-like, anal canal drainage is mostly adopted in nursing to lead out the stool in the rectum or an anal bag is adopted to collect the stool, but the phenomenon that liquid seeps to contaminate the skin near the anus to cause local skin inflammation is inevitable; therefore, the nursing staff needs to frequently replace the patient hip pad, scrub the skin around the anus, replace clothes and the like, and the nursing difficulty is greatly increased. Some hospitals adopt the trachea cannula to replace the anal canal for drainage operation, thereby obtaining better effect.

Therefore, there is a need for an anal drainage device based on endotracheal intubation.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an anal canal drainage device based on trachea cannula, prevent seepage.

Another object of the present invention is to provide an anal canal drainage device capable of forming negative pressure.

In order to solve the technical problem, the utility model discloses a simple negative pressure anal canal drainage device, which comprises an insertion tube and a drainage bag detachably connected with the lower end of the insertion tube, wherein the upper part of the insertion tube is connected with a first air bag in a surrounding way, the lower part of the insertion tube is provided with a first inflation nozzle, and the first air bag is connected with the first inflation nozzle through an inflation tube;

the outer side of the drainage bag is sleeved with a second air bag group, the second air bag group comprises a plurality of horizontally arranged annular air bags and a plurality of strip-shaped air bags which are arranged perpendicular to the annular air bags, the annular air bags are communicated with the strip-shaped air bags, and the second air bag group is provided with a second inflating nozzle; the second air bag group supports the drainage bag in a full air state, so that the drainage bag reaches the maximum volume and forms negative pressure.

Preferably, the cannula and the drainage bag are connected by a connector thread.

Preferably, the inflation tube is arranged inside the cannula lumen.

Preferably, the surface of the first air bag is provided with a plurality of annular bulges for preventing skid and leakage.

Preferably, the drainage bag is provided with scales.

Preferably, the maximum volume of the drainage bag is not less than 500 ml.

Preferably, the cannula is provided with length scales.

The utility model discloses a simple and easy negative pressure anal canal drainage device has following advantage at least:

the utility model discloses a simple and easy negative pressure anal canal drainage device simple structure can effectively prevent the seepage, and the back is aerifyd to the second gasbag group, can temporarily form the negative pressure and force the patient to defecate and flow, and drainage bag detachable uses, and the drainage bag collect after full change new drainage bag can, and needn't insert the intubate again, reducible patient is painful to reduce treatment cost.

Drawings

Fig. 1 is a schematic structural view of a simple negative pressure anal canal drainage device.

The reference numbers in the figures are: 1-cannula, 2-drainage bag, 3-first air bag, 4-first inflation nozzle, 5-inflation tube, 6-second air bag group, 610-annular air bag, 620-strip air bag, 630-second inflation nozzle, 7-annular bulge and 8-connecting piece.

Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in figure 1, the simple negative pressure anal canal drainage device comprises an insertion tube 1 and a drainage bag 2 detachably connected with the lower end of the insertion tube, wherein the upper part of the insertion tube is connected with a first air bag 3 in a surrounding manner, the lower part of the insertion tube is provided with a first inflating nozzle 4, and the first air bag is connected with the first inflating nozzle through an inflating tube 5;

a second air bag group 6 is sleeved on the outer side of the drainage bag, the second air bag group comprises three horizontally arranged annular air bags 610 and a plurality of strip-shaped air bags 620 which are perpendicular to the annular air bags, the annular air bags are communicated with the strip-shaped air bags, and a second inflating nozzle 630 is arranged on the second air bag group; the second air bag group supports the drainage bag in a full air state, so that the drainage bag reaches the maximum volume and forms negative pressure.

The intubation tube is in threaded connection with the drainage bag through a connecting piece 8.

The inflation tube is arranged on the inner side of the cannula tube cavity. The gas tube is arranged on the inner side, so that the flatness and the tightness of the outer wall of the cannula cannot be influenced, and leakage is prevented.

The surface of the first air bag is provided with a plurality of annular bulges 7 for preventing skidding and leakage.

The drainage bag is provided with scales. According to the scale, the insertion depth is different for different patients.
