Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] The threaded rod 9 of the base is screwed with the threaded hole at the lower end of the force sensor 8, the threaded rod 15 at the lower end of the connecting rod is screwed with the threaded hole at the upper end of the force sensor 8, and after the needle plastic tube 17 is fixedly connected with the lower end of the needle 1, put the needle 1 into the In the middle of the clip 4 at the upper end of the connecting rod 5 , after putting the cap 2 over the metal needle of the needle 1 , cover it on the clip 4 at the upper end of the connecting rod 5 to fix the needle 1 .

[0020] After the above-mentioned parts are assembled, they are fixed in the shell 7 together. The lower circular chassis 11 of the base 12 is snapped into the lower half of the circular slot 10 of the housing 7, and by adjusting the depth at which the connecting rod 5 is screwed into the forc...

Abstract

The invention relates to a novel quantifiable intravenous injection and puncture simulation training device, including a shell, a syringe needle, a cap, a connecting rod, a base and a force sensor. The syringe needle is clamped on the connecting rod and is connected with the force sensor, the force sensor is fixed to the shell through the base, and puncture force is transmitted to the force sensor through the connecting rod, thereby realizing measurement of the puncture force. The beneficial effects of the novel quantifiable intravenous injection and puncture simulation training device provided by the invention are that a blood return situation is observed through a special extraction method of a syringe needle plastic tube; and the puncture force can be measured in real time, a change of the puncture force in processes that the syringe needle misses a blood vessel and advances after stabbing into the blood vessel is displayed, the internal structure limits a maximum stroke of movement of the syringe needle, thereby protecting the force sensor from being damaged, and medical staff reduce the puncture force by adjusting a technical action, thereby achieving an optimal injection and puncture training effect. In addition, small and exquisite design of the device enables the device to be similar to a real application situation, thereby facilitating transition of the technical action mastered by the medical staff from practice to clinical application.

Description

technical field [0001] The invention belongs to the fields of clinical medicine and biomechanics, and relates to a novel quantifiable intravenous injection and puncture simulation training device. Background technique [0002] Intravenous injection and puncture are commonly used and very important technical means in clinical practice, and they are invasive. During the process of intravenous injection and puncture, it is easy to cause pain to patients. If puncture fails, it will aggravate the pain of patients. For children and the elderly, the damage caused is more significant and affects Curative effect, for the rescue of critically ill patients, a successful puncture is very important, if the operation is not done properly, it may be life-threatening. Therefore, as a medical staff, it is very important to be proficient in intravenous injection and puncture techniques. As a clinical technology, the improvement of intravenous injection and puncture technology requires medica...
