Description

Disposable sterile protective bag for hemodialysis catheter

Technical Field

The utility model belongs to the field of medical auxiliary equipment, a disposable aseptic protection bag of pipe is passed through to blood is related to.

Background

Hemodialysis is one of the kidney replacement treatment modes of patients with acute and chronic renal failure. The blood and electrolyte solution (dialysate) with similar concentration of organism are arranged inside and outside one hollow fiber by draining the blood in vivo to the outside of the body through a dialyzer consisting of a plurality of hollow fibers, and the material exchange is carried out by dispersion/convection, thereby removing the metabolic waste in the body and maintaining the balance of electrolyte and acid-base; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis.

After a patient with chronic renal failure is subjected to maintenance hemodialysis treatment, the survival time of the patient is long, a stable and reliable hemodialysis access is a basic guarantee for long-term dialysis, and partial patients are one of the best methods because of poor vascular conditions, and arteriovenous internal fistula cannot be established or an indwelling deep venous double-lumen catheter cannot be maintained for a long time to serve as a permanent vascular access.

In the hemodialysis activity, in order to prevent inflammation, a hemodialysis catheter used by a patient needs to be fixed on the patient, and a joint needs to be wrapped so as to avoid external contact pollution, the current method for wrapping the catheter by simple gauze clinically has the defects of inconvenient use and operation, for example, when a red/blue end is polluted by bacteria, the other red/blue end is easily infected, cross infection is caused, certain difficulty is brought to disassembly due to irregular adhesive plaster adhesion, and the like, and the gauze is not tightly wrapped, so that the catheter is easily polluted by external bacteria to cause infection; the gauze wrapping the catheter is not adhered to the catheter, and is easy to shift and fall off; the adhesive plaster stuck on the skin in front of the chest is not easy to be used for home care (bathing and cleaning), and the skin is easy to be allergic to the adhesive plaster; the catheter is easy to fall off and shift, and if the catheter is pulled by external force, the catheter is easy to fall off, so that potential safety hazards are caused, a lot of inconvenience in operation is caused to medical workers in the actual use process, and meanwhile, a lot of inconvenience is brought to the use of patients.

Although CN201721082047.2 discloses a disposable sterile protection bag for a hemodialysis catheter, the principle is that the disposable hemodialysis catheter is placed in a wrapping bag, the disposable hemodialysis catheter is fixed on a patient by using a back adhesive layer on the back of an inner fixing sheet at the inner side of the wrapping bag, and the lower end of the disposable hemodialysis catheter can be connected with a connecting pipe of hemodialysis equipment through an upper channel bag opening with an upper sealing pressing strip sleeve; the label written on the upper part of the outer layer fixing adhesive tape can be used for noting medical advice matters, and when hemodialysis is finished, the disposable hemodialysis catheter can be tightly sealed in the packaging bag by using the sealing layering sleeve, so that the external contact pollution of the disposable hemodialysis catheter can be avoided; the device passes through back viscose layer to be fixed on one's body at patient, glues on one's body for a long time, can cause patient's skin discomfort or skin allergy ulcerate even, and after the hemodialysis, also do not make things convenient for the patient to walk or move, and skin can sweat very easily takes place to drop.

One side of the fixed paste is provided with a magic paste female paste B, and the other side of the fixed paste is provided with a magic paste sub-paste B so as to enable the fixed paste to bind the two ends of the binding belt and then clamp the binding belt between the binding belt and the skin, thereby avoiding discomfort of the two ends of the binding belt to the skin of a patient in a messy state.

The utility model discloses a theory of operation:

after the hemodialysis of a patient is finished, a medical worker sterilizes the hemodialysis catheter, seals the catheter, screws a heparin cap, presses a snap fastener, loosens a binding belt, expands the opening of a packaging bag, sleeves the packaging bag into the hemodialysis catheter, separates the hemodialysis catheter from a red catheter at the moment by an interlayer, completely sleeves the hemodialysis catheter by an aseptic gauze sleeve, presses the snap fastener, and contracts the binding belt, so that the opening of the packaging bag completely wraps the head of the hemodialysis catheter, thereby achieving the effect of sealing and isolating bacteria; and then the whole packaging bag is fixed at the installation position of the hemodialysis catheter by obliquely crossing and tying the packaging bag to the shoulder of the human body through a binding band.

Compared with the prior art, the utility model has the advantages and beneficial effect as follows:

1. the utility model discloses increase parcel bag and parcel bag sack and adopt the design in constraint area, can effectively seal the blood and pass through the pipe, prevent the pollution of bacterium, parcel bag easy dismounting moreover, easily medical personnel pass through the change of the aseptic parcel of pipe to disposable blood, easy operation is convenient, and the device cost is cheap, adopts disposable use, and is extremely low to the pollution rate that the pipe was passed through to blood.

2. The utility model discloses an increase aseptic gauze cover, the pipe is passed through to laminating blood, and the difficult displacement that takes place maintains the sterile environment that the pipe is passed through to blood.

3. The utility model discloses a through the red blue pipe parcel of interlayer with the blood pipe of passing through, and separate and come, the red blue pipe is separated the management and is avoided cross infection.
