Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0027] see figure 1 , The embodiment is made up of parts such as needle head 1, air bag 2, soft rubber pad 3 and extension rod 4.

[0028] see Figure 4 , the needle is an elongated medical needle, and the rear end of the needle point 10 of the needle is a needle tube 11 with an enlarged diameter.

[0029] see Figure 5 , Image 6 , the airbag is made of flexible transparent plastic, so as to observe the liquid inside; the airbag is cylindrical, and the front and rear ends of the airbag are in a hemispherical shape; the neck 21 at the front end is used to attach needles; The thin wall of the cylinder makes the air bag easy to pinch. The front end of the airbag is shaped on three cards 23 that are staggered from each other by 120 degrees, and the cards 23 can be made into an inverted trapezoidal shape.

[0030] see Figure 7 , Figu...

Abstract

The tympanic membrane aspiration syringe belongs to medical equipment; the invention includes a needle and an air bag, and is characterized in that it also has a soft rubber pad and an extension rod; the neck of the front end of the air bag is connected with the needle; the soft rubber pad surrounds the outside of the air bag, and the soft rubber pad The front end has a block, the rear end of the soft rubber pad has a base, and the base is fixed on the front end of the extension rod. The invention adopts the posture of holding a pen to treat the tympanic membrane. The design of the product can well adapt to the physiological characteristics of people, making it more convenient and easy for doctors to work, and the puncture positioning is more accurate and safe; the invention is suitable for use in medical departments at all levels.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a tympanic membrane puncture device. Background technique [0002] The most widely used method in tympanocentesis is to use a conventional syringe (mostly 1ml, 2ml or 5ml syringe) connected to a long thin needle (mostly No. 7 needle), and the doctor will pierce it into the back of the tympanic membrane with one hand. Tympanum, and then use the other hand to pull the injection handle of the syringe back to realize the injection of the tympanic fluid into the syringe; when injecting medicine into the tympanic cavity, the doctor holds the needle and fixes it with one hand, and pushes the injection handle of the syringe with the other hand; this technique The solution needs to be completed with the help of light sources such as the reflection of the doctor's forehead mirror or headlights. [0003] With the gradual popularization of ear endoscopes, it is becoming more and more common for doctors ...
