Description

Fingertip pusher for manual fingertip blood collection

Technical field

The present invention relates to the technical field of medical appliances, and in particular to a finger-side pusher for manual fingertip blood collection.

Background technique

Diabetic patients rely on insulin to control blood sugar and must always pay attention to changes in their own blood sugar. It has become routine to measure blood sugar before and after meals. As the most convenient method, fingertip blood testing for blood sugar testing has been recognized and promoted, and can be easily implemented not only in hospitals and clinics, but also at home.

However, due to the complications of diabetes and differences in personal physique, blood collection operations must be completed four or more times a day, which has also brought a lot of inconvenience to patients. For example, the amount of blood after puncture is too little, squeezing causes interstitial fluid to precipitate and affects the test results, the wound is too large, and the pain is great. In terms of current testing technology, fingertip blood sampling for blood glucose testing requires high blood purity during the collection process and is not standardized. The operation will affect the quality of blood glucose testing. For example, the dilution of blood by tissue fluid will reduce blood glucose values, and less blood volume will affect the test results.

Personal self-service blood glucose testing must also rely on fingertip blood collection, standardize blood collection operating procedures, popularize reasonable and effective blood squeezing operations in clinical practice, and minimize the pain and inconvenience during acupuncture blood collection. For the majority of diabetic patients, it is expected and Real needs.

"Low amount of bleeding due to needle stick" is a very common problem that occurs during fingertip blood collection in diabetic patients, or poor blood circulation caused by poor peripheral circulation in the elderly, obesity, low ambient temperature, or other complications. Although there are various "standard specifications", such as hanging the arm for 15 seconds before blood collection, shaking hands, rubbing hands, soaking in hot water and other methods to increase peripheral blood circulation and filling the peripheral blood; collecting blood from the side of the fingertip; deepening the puncture depth, etc. However, in most cases, it is still necessary to rely on "squeezing" bleeding, and irregular extrusion techniques directly affect the test results. For example, it is common for the thumb to squeeze the periphery of the fingertip puncture, causing tissue fluid to be squeezed out and diluting the blood.

In the clinical field, medical staff rely on clinical experience and finger blood vessel distribution characteristics to often use the finger side pushing method to solve the problem of small bleeding. The key point is: by gently pushing the blood vessels on both sides of the fingertips to the front of the finger, The blood in the blood vessels on the finger side is squeezed toward the fingertips, allowing the blood to slowly overflow from the wound to avoid tissue fluid from escaping with the blood when the periphery of the wound is squeezed. Based on this empirical standard, this patent is disclosed, and the instrument is used to realize the standardized blood squeezing operation process and ensure the accuracy of blood glucose test results.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned phenomenon in the prior art that in the process of blood glucose testing for diabetic patients, the blood volume is insufficient when fingertips are collected, and the interstitial fluid dilutes the blood and the red blood cells are squeezed and destroyed due to irregular extrusion, resulting in inaccurate detection. A finger-side pusher for manual fingertip blood collection is provided.

A finger-side pusher for manual fingertip blood collection, which is composed of a fixed frame and a pushing structure, and the pushing structure is arranged on the fixed frame;

The fixed frame includes a first fixed block and a second fixed block, the first fixed block and the second fixed block are connected and fixed, and the first fixed block and the second fixed block have the same structure;

The first fixed block has a first sliding groove and a second sliding groove, and the first sliding groove and the second sliding groove have the same structure;

The pushing structure includes a first pushing structure and a second pushing structure, and the first pushing structure and the second pushing structure have the same structure;

The first pushing structure has a rotating shaft, an adjusting block, a pushing slide block and a return spring. The adjusting blocks are set at both ends of the rotating shaft and are respectively arranged in the first sliding groove and the second sliding groove. The pushing slide block It is placed on the rotating shaft, and the return spring is inserted and fixed in the adjusting block.

Working principle and process of the present invention:

When in use, slide the adjusting block outward, the patient inserts his finger from the connecting through hole of the first fixed block and the second fixed block, loosen the adjusting block, and the return spring returns to its position. At this time, the patient's finger is clamped. Then the patient uses the other hand or under the operation of the medical staff, the first pushing structure and the second pushing structure rotate along both sides of the finger, and by gently pushing the blood vessels on both sides of the fingertip to the front of the finger, the finger side The blood in the blood vessel is squeezed towards the fingertip, allowing the blood to slowly overflow from the wound. After the operation is completed, slide the adjustment block outward again, the through hole will expand, and the patient can take out the finger.

Beneficial effects of the present invention:

1. The present invention has a simple structure, is easy to use, and has strong practicability. It standardizes the squeezing operation technique during finger blood collection in order to obtain accurate blood test results;

2. The present invention helps to reduce the size of the puncture needle, lower the depth of the puncture, reduce the wound surface, reduce the puncture pain, reduce the psychological and physiological burden on diabetic patients, and also reduce the workload of medical staff;

3. The present invention has low cost and is suitable for widespread promotion and application.
