Abstract

An anti-needlestick sterile urine collection kit includes a supporting device, a needle, a connecting head, a hose, a connecting arm, an elastic device, a releasable clamping device, a test tube and a stopper. The supporting device is detachably fixed on a urinary catheter. The connecting head is detachably attached to the supporting device. The hose is connected between a tail end of the needle and the connecting head. A free end of the connecting arm is attached to the tail end of the needle. The releasable clamping device is operated to release the elastic device clamped by the releasable clamping element such that the free end of the elastic device actuates the connecting arm to rotate from a first position to a second position relative to the supporting device to cause a tip of the needle to puncture into the urinary catheter. The connecting head penetrates the stopper, and a urine in the urinary catheter is sucked into the test tube through the needle, the hose and the connecting head due to a negative pressure in an interior of the test tube.

Description

Anti-needle stick sterile urine collection kit

The present invention relates to a needlestick-proof sterile urine collection kit, and in particular to a needlestick-proof sterile urine collection kit that can safely, quickly and accurately collect urine samples.

When a patient is bedridden and unable to urinate on his own, a retention catheter is placed on the patient. If the patient's urine needs to be collected for testing, the urine sample will be taken directly from a certain section of the urinary catheter.

The current practice for medical staff to collect urine from patients through urinary catheters is to first clean their hands with soap and water. Then, the medical staff adjusts the urinary catheter to properly expose the part of the urinary catheter where urine is collected. Then, the medical staff disinfected the catheter with sterile cotton swabs and 75% alcohol. Next, the medical staff uses an empty needle to extract 8 to 10 mL of urine from the exposed catheter site using sterile techniques. Finally, the medical staff pours the urine from the empty needle into a sterile container, and quickly closes and locks the lid of the container. It should be emphasized that urine samples cannot be collected from urine bags.

However, the current method of collecting urine from patients is to puncture the urinary catheter with an empty needle with a capacity of 10 ml, and then use back-aspiration to obtain the urine. This process will cause five problems: (1) There is no support for the empty needle during puncture. The needle is often used to draw urine in a suspended manner, so the operator's finger is often accidentally pricked by the needle; (2) When drawing urine, the position of the punctured urethra cannot be correctly judged, which may result in the fixed urethral opening being pulled out. Distilled water or saline solution in the urinary catheter water balloon instead of urine will cause incorrect test results; (3) When using an empty needle to draw urine, the operator must fix the needle with one hand and slowly withdraw the needle center with the other hand. Due to the principle of negative pressure in the syringe, resistance will be generated when urine is withdrawn, resulting in the inability to obtain at least 8ml of urine at a time; (4) after the urine extraction is completed, the needle must be removed, and this process also increases the operator's risk of needle stick; (5) Finally, the urine in the syringe must be poured into the test tube and then sent to the laboratory. There is a risk of contamination of the urine sample. In the process of pouring urine into test tubes, aseptic techniques are greatly reduced due to too many uncertainties in the operating environment. Moreover, during the process of injecting urine from the syringe into the test tube, the urine sample will deteriorate due to contact with the air or be contaminated by contact with the open external environment. In addition, the urine sample is often carelessly injected, resulting in urine leakage. liquid flows out, thereby affecting the accuracy of the numerical value.

At present, no relevant technology has been developed or proposed that can assist medical staff to collect urine samples safely, quickly and accurately.

Therefore, one of the technical problems to be solved by the present invention is to provide a needle stick-proof sterile urine collection kit that can assist medical staff to collect urine samples safely, quickly and accurately.
