Description

Excrement drainage device

Technical Field

The utility model relates to the field of medical instruments, in particular to a stool drainage device.

Background

Fecal incontinence is often seen in critically ill patients with poisoning, coma, craniocerebral trauma, spinal cord injury and the like, but fecal incontinence easily causes the skin around the anus to be wet, soaked or even broken, which causes discomfort, pain, skin injury and even pressure injury of the patients, and also causes certain psychological burden to the patients. Therefore, there is a need for a medical device for collecting and nursing excrement such as feces in patients with rectal, colonic or ileoastomy (artificial anus) and patients with fecal incontinence.

Two anus bags are available in the market at present, one is an anus bag with a chassis, the chassis is separated from a stool collection bag, when the anus bag is used, a stoma or the periphery of an anus is cleaned and kept dry, a hole with proper size and shape is cut on the chassis according to the shape and the size of the stoma or the anus, then the chassis is tightly attached to the skin along the stoma or the anus, the collection bag is arranged on the chassis, a lock ring is locked, a discharge port at the lower end of the collection bag is tightly sealed, and when the stool exists, a sealing clamp is opened to empty the collection bag and clean the collection bag; one is a bottomless anus bag, which is used to clean and dry the stoma or the anus, cut the skin adhesion part into the right size according to the shape and size of the stoma or the anus, blow a small amount of air into the bag, adhere the stoma bag on the stoma or the skin around the anus, seal the discharge port at the lower end of the collection bag tightly, open the sealing clamp when in excrement, empty the collection bag and clean.

The two prior arts described above have the following disadvantages:

1. the texture of the part stuck with the skin is hard, the stickiness is not strong, the skin around the anus is uneven, the bag is easy to be broken due to unstable sticking, and the economic burden of a patient is increased;

2. the stoma is manually cut into the size and the shape, the edge of the stoma is irregular, and the stoma can extrude the skin to cause pressure injury due to the hard texture;

3. excrement and anus combustion gas can only be collected in the bag, need the nurse to open repeatedly and collect bag clearance excrement and clean anus bag, will cause the broken bag of anus bag not implement like this, increases patient's economic burden, and it is very inconvenient to clear up excrement from the bag in addition, causes the pollution again easily, can let nurse's work load greatly increased like this simultaneously.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects and shortcomings of the technical problems, the utility model provides the excrement drainage device which can effectively reduce pressure injury of perianal skin and improve the comfort of a patient; the negative pressure drainage reduces because of the bag body that the excrement accumulation leads to breaks, and the condition of frequent change alleviates patient's burden, reduces nurse's work load.

A stool drainage device comprises an anal bag, a drainage tube and a drainage bag, wherein an apple-shaped anal opening is formed in the top of the anal bag, and a fixing disc is arranged on the outer ring of the anal opening; one end of the drainage tube is connected with the bottom of the anal bag, the other end of the drainage tube is connected with the drainage bag, and a drainage clamp is arranged on the drainage tube; the drainage bag is internally provided with a spring which plays a supporting role, and the top of the drainage bag is provided with an air vent.

Furthermore, the anus opening is made of soft silica gel, and is 3.5cm long and 4cm wide.

Furthermore, the fixed disk is made of silica gel, and is 9cm long and 9cm wide.

Furthermore, the fixed disk outside is provided with the cockscomb structure and pastes the area, paste the material of taking and be the silica gel, long 2cm, wide 1cm, the corner is circular.

Furthermore, a non-woven fabric layer is arranged at the contact part of the anal pouch and the skin.

Furthermore, the connectors at the two ends of the drainage tube are made of hard plastics.

Furthermore, but the connector of anus bag and drainage bag is automatic closure, and the material is silica gel.

Furthermore, the drainage bag is a negative pressure drainage bag.

Furthermore, the drainage bag is in a circular cylinder shape, the diameter of the drainage bag is 15cm, and the drainage bag is made of elastic plastics.

Furthermore, the air vent is externally connected with a soft rubber tube, and an air clamp is arranged at the tube opening and is a Z-shaped clamp.

The utility model has the beneficial effects that:

1. the pasting position of the anus bag and the anus is designed into an apple shape which is convenient to fix, the material is soft silica gel, manual shearing is not needed when the anus bag is used, and pressure injury to the skin around the anus caused by too hard material and irregular edge is avoided;

2. the adhesive tape at the sticking position is a silica gel sticking tape, the edge is in a zigzag shape, the tooth tip is round, the adhesiveness is strong, the edge curling is not easy, and the replacement of the anus bag is reduced, so that the economic burden of a patient is lightened;

3. the negative pressure drainage device is connected outside the collection bag, excrement drained from the anal bag is timely discharged into the negative pressure drainage bag, and the phenomenon that the collection bag is broken due to accumulation of excrement and gas exhausted from the anus in the collection bag is avoided; meanwhile, the skin injury caused by the impregnation of excrement to the skin in the bag is also reduced; need not the nurse to open and collect the bag and seal the clamp and clear up shit and clean the collection bag, the nurse's that has significantly reduced work load.
