Problems solved by technology

[0005] 2. When pulling out the needle tube while fixing the anesthesia catheter, it is better to pull out the needle tube smoothly without any movement of the anesthesia catheter relative to the patient. At this time, the operation of pulling out the needle tube will often bring out the anesthesia catheter, resulting in the insertion of the anesthesia catheter. Failure is also the most difficult point in the entire anesthesia process

Embodiment Construction

[0027] like Figure 1~6 shown, see figure 1 , 2 , 3, a kind of adjustable anesthesia catheter system of the present invention comprises

[0028] a needle tube 100 for insertion into a patient;

[0029] Anesthesia catheter 200, which is used to input medicine, is arranged in the needle tube 100;

[0030] Tube base 300, which is used to fix the needle tube 100, and a support ring 301 is fixed on its outer surface;

[0031] The adjustable needle puller 400 is between the support ring 301 of the tube base 300 and the patient, and the two horseshoe-shaped support blocks are separated by a guiding structure, so that the needle tube 100 is pulled out perpendicular to the patient, and the needle tube 100 is pulled out through the rack and pinion mechanism Drive the two rollers to move the anesthesia catheter 200 towards the patient.

[0032] Through the above structure, the present invention can bypass the position of the patient's small bulge through the horseshoe-shaped support...

Abstract

The invention provides an adjustable anesthetic catheter system. The system comprises a needle tubing (100), an anesthetic catheter (200), a tube seat (300) and an adjustable needle withdrawal part (400), wherein two horseshoe-shaped support blocks can be separated between the supporting ring (301) of the tube seat (300) and a patient by a guiding structure, so that the needle tubing (100) can bepulled out vertical to the patient; and two rollers are driven through a rack and pinion mechanism to stir the anesthetic catheter (200) toward the patient. Through the structure, firstly, the needletubing (100) can be pulled out smoothly without secondary injury caused by tissue stretching since the needle tubing (100) is pulled out obliquely; and secondly, the anesthetic catheter (200) is prevented from being pulled out along with the needle tubing (100).

Description

technical field [0001] The invention relates to an anesthesia appliance, in particular to an adjustable anesthesia catheter system for epidural block anesthesia. Background technique [0002] Epidural block is a widely used anesthesia method in clinic. During anesthesia, in the median approach operation, 1% lidocaine needs to be infiltrated into the skin, subcutaneous, and interspinous ligament layer by layer. At this time, a small bulge will appear on the skin at the injection point or puncture point. In the operation of the circumstantial approach, the needle tube avoids the supraspinous ligament and the supraspinous ligament and goes directly to the ligamentum flavum, and then the catheter is placed. During the catheterization operation, after confirming that the puncture needle of the needle tube has entered the epidural space, the anesthesia catheter for continuous injection of medicine can be slowly injected into the epidural space through the needle tube, and the ca...
