Touch-sensing injection needle leakage detecting device

The present invention provides a leakage detecting device, in particular, a touch sensing injection needle leakage detecting device which is accurate and sensitive to detect leakage and has a small size and is convenient to use.

According to medical treatment, in order to inject the medicine into the body of the patient, most of them are carried out by means of injection. Clinically, the injection method often used when injecting the medicine into the body is injected or is assisted by an automatic injection device. That is, the needle enters the blood vessels of the body and injects the drug into the blood vessel and enters the body; in medical institutions, many medical or examination items are often used for drug injection, because the blood vessels vary in different parts of the body, and the blood vessels The state of the body may also change due to a number of physical conditions, especially in the medical practice of using an auxiliary automatic injection device for injection, often because the injection force set by the machine is too large and is not easily detected by the medical staff immediately, so that the needle body displacement occurs. The occurrence of rupture of blood vessels causes the injection of the drug to be incorrectly injected into the blood vessel of the patient, causing the patient to have abnormal swelling of the body surface at the site of the application, causing so-called medical negligence of the injection of the injection or causing physical damage to the subject. Medical Dispute.

As shown in the first figure, it is a schematic diagram of a conventional pneumatic injection injection leak detecting device, which is mainly composed of a control device 91, an inflator 92 and a cover device 93. The inflator 92 and the control device 91 are included. The gas output device is connected, so that the inflator 92 is inflated. After the inflation is completed, the injection needle 94 is traversed by the through hole in the center of the inflator 92 and left in the human blood vessel where the injection is expected to be applied, and then inflated. The device 92 is fixedly attached to the surface of the skin to which the injection is intended to be applied, while the cover device 93 is pressed against the inflator 92 and the inflator 92 is pressed against the surface of the injection position, due to the inner side of the cover device 93. A pressure sensing element for sensing the initial distribution and subsequent changes of the gas at each point in the inflator 92 is provided, so that it is possible to determine whether or not leakage has occurred.

However, in actual use, the inflator 92 needs to be inflated to a specific pressure each time, which is troublesome, and the inflator 92 is prone to uneven force application, which makes it impossible to accurately determine the leakage or not, and the volume and weight are difficult to be reduced. It is inconvenient to carry, and the refilling device 92 and the cover device 93 will shield the injection site and cannot be visually assisted.

Therefore, how to solve the above problems and deficiencies in the past, that is, the applicants of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party assessment and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed such accurate and sensitive detection. A new type of patented touch-sensing injection leak detection device that is leaky and small in size.

The main purpose of this new type is to be sensitive and accurate to detect leaks.

Another main purpose of this new model is to make it easier to use and carry.

In order to achieve the above object, the main structure of the present invention includes a device body, and one side of the device body is provided with a touch detection device for detecting changes in the body surface of the user, and the device body is provided with a touch detection device. The control device of the information connection device is used for controlling the action when the touch detection device detects that the user's body surface changes; and the application of the present invention places the device body on the user and uses the touch detection The measuring device is attached to the user's body surface, and a needle is injected from the side of the touch detecting device to the user. If the needle is not inserted into the blood vessel or the injection force is too strong, the blood vessel is broken, causing the user to rupture. The swelling of the body surface occurs, that is, the user swallows the swelling area of the body surface due to leakage of the injection at the injection site of the injection, and the touch detection device detects the protrusion and transmits a message to the control device, and controls the device to actuate Sending a warning such as sound or light or sending a signal to interrupt the injection. With the above technology, the use of the conventional pneumatic injection leak detection device is troublesome and easy to judge. Leakage distortion problems to be breakthroughs to achieve accurate and sensitive detection of leakage circumstances and the small size of the ease of use of practical progress.
