Description

A PROTECTIVE APPARATUS SUITABLE FOR USE IN PERIPHERAL VENOUS

ACCESS APPLICATIONS

Technical Field

This invention relates to an apparatus which prevent the patient or the items in the surrounding to be contaminated with blood by protecting the vessel access point in peripheral venous catheter and injector applications for blood drawing, intravenous drug applications and fluid treatment.

State of the Art

Peripheral venous catheter and injector applications for blood drawing, intravenous drug applications and fluid treatment are applied to the most of the admitted or hospitalized patients. During this application, it is very important that the blood coming out of the vessel does not touch any surface in terms of preventing infections. However, blood coming out of the vein during the application has the risk of contaminating sometimes the patient's own skin, sometimes the skin of the practicing health care personnel, sometimes the patient's clothing, the chair armrest, or the floor.

Living surfaces contaminated with blood are cleaned with skin antiseptic and thereby, growth of microorganisms is prevented. Nonliving surfaces, on the other hand, are often wiped out with only water or only disinfected with disinfectants. Although applications may vary according to the policies of the institutions, only disinfection can be provided in most of the institutions. Similar to the skin antiseptics, the disinfection process only stops the growth of microorganisms. Since blood is both a source for growth and reproduction of microorganisms and one of the most important ways of carrying microorganisms, preventing the risk of blood contamination in peripheral venous access is of critical importance especially for preventing infections.

Patients who have to come into contact with surfaces contaminated with else's blood may experience psychosocial problems such as disgust and anxiety, and patient comfort may be impaired. Furthermore, the difficulty of eliminating traces of blood on patient beds, bed sheets, mattresses and pillows means an extra workforce and creates a serious economic burden.

In the literature, use of treatment fabric and cloth is recommended in peripheral venous access applications to prevent blood contamination, but unfortunately, in practical applications in health care settings, it is observed that the use of these protective equipment materials is not preferred. As a result, traces of blood can be found on many surfaces. This condition is too frequent to follow and poses a serious risk for infection. It is reported that infections related to peripheral venous catheters and injectors constitute approximately 80 - 90 % of the blood circulation - related infections that develop in the hospital environment.

More than one documents can be found in the technique on finding and eliminating the causes of these infections.

In one of them, the patent document CN108324291 A; an injector connected to a valve system that prevents the blood flowing back from the injector is mentioned. With the invention, it is prevented that the blood drawn from the patient and possibly contaminated with bacteria contact to flow backward into the patient's body when drawing a blood sample. It has been thereby stated that the costs regarding the sterilization of blood sample tubes may be reduced.

Another document of in technique, the utility model document number CN203446618A describes a hospital gown. There are openings in certain areas of the dress such as neck, waist, chest that can be opened when necessary. These openings can be opened or closed in case of blood expulsion, patient vomiting, or any kind of fluid overflow, preventing contamination.

When the current technique was examined, no apparatus which prevent the bleeding to contaminate the points other than the point of application when still in the point that they are developed are found.

When the studies and improvements to prevent infections due to contamination are considered, a protection apparatus that can be applied directly to the patient's skin on the related limb, allowing catheter / injector access while at the same time preventing blood to flow outside the application point, is still needed.
