Description
技术领域technical field
本发明涉及一种麻醉过程中的给药装置，特别涉及一种全身麻醉自动治疗支气管痉挛的给药装置。The invention relates to a drug delivery device during anesthesia, in particular to a drug delivery device for automatic treatment of bronchospasm under general anesthesia.
背景技术Background technique
呼吸道痉挛一般指喉头,气管,支气管,细支气管,终末支气管的平滑肌剧烈收缩,引起的管腔狭窄,导致气道梗阻。主要原因是由于呼吸道粘膜过于敏感，当遇到过敏源或气温变化时，造成呼吸道痉挛，多发生在幼儿以及过敏体质者。Respiratory spasm generally refers to the severe contraction of smooth muscles in the larynx, trachea, bronchi, bronchioles, and terminal bronchi, resulting in narrowing of the lumen, resulting in airway obstruction. The main reason is that the mucous membrane of the respiratory tract is too sensitive. When encountering allergens or temperature changes, it will cause respiratory spasm, which mostly occurs in young children and those with allergic constitution.
在一些大的手术过程中，麻醉剂与氧气混合后，通过气管送入病人体内，以维持手术的进行。In some major procedures, anesthesia is mixed with oxygen and delivered to the patient through the trachea to keep the operation going.
在手术过程中，病人有时会发生呼吸道痉挛，导致气道梗阻，阻止麻醉剂进入体内。这时，需要医生紧急给病人注射或喷入防痉挛的药物。During surgery, patients sometimes experience airway spasms that block the airways and prevent the anesthetic from entering the body. At this time, the doctor needs to urgently inject or spray the patient with antispasmodic drugs.
但是，上述过程都需要人工进行操作，且没有一种全身麻醉过程中能自动给药的装置。However, the above processes all require manual operations, and there is no device that can automatically administer drugs during general anesthesia.
发明内容SUMMARY OF THE INVENTION
针对上述问题，本发明所解决的技术问题是，在全身麻醉过程中，当出现支气管痉挛时，提供一种全身麻醉自动治疗支气管痉挛的给药装置，可以自动喷入治疗痉挛药物，解除痉挛，防止病人窒息。In view of the above problems, the technical problem solved by the present invention is to provide a drug delivery device for automatic treatment of bronchospasm under general anesthesia when bronchospasm occurs in the process of general anesthesia, which can automatically inject drugs for the treatment of spasm to relieve spasm, Prevent the patient from suffocating.
本发明是通过以下措施来实现的The present invention is achieved by the following measures
本发明公开了一种全身麻醉自动治疗支气管痉挛的给药装置，包括提供麻醉药物的麻醉机、连接在麻醉机和人体之间的螺纹管，其特征在于：所述的螺纹管通过气缸管连接有一气缸，所述气缸的活塞上固定有一气缸轴，气缸轴的上端套有一气缸轴套，气缸轴的上端设置有一弹簧；所述气缸轴套上还设置有一个与气缸轴相交叉的导药管，导药管的一端连接有药物瓶、另一端连接螺纹管；所述气缸轴与导药管相交叉处设置有一能与导药管相通的通孔。The invention discloses a drug delivery device for automatic treatment of bronchospasm by general anesthesia, comprising an anesthesia machine for providing anesthetic drugs, a threaded pipe connected between the anesthesia machine and a human body, and characterized in that the threaded pipe is connected through a cylinder pipe There is a cylinder, a cylinder shaft is fixed on the piston of the cylinder, the upper end of the cylinder shaft is sleeved with a cylinder shaft sleeve, and the upper end of the cylinder shaft is provided with a spring; the cylinder sleeve is also provided with a medicine guide that intersects with the cylinder shaft One end of the medicine guiding tube is connected with a medicine bottle, and the other end is connected with a threaded pipe; the intersection of the cylinder shaft and the medicine guiding tube is provided with a through hole which can communicate with the medicine guiding tube.
上述本发明的全身麻醉自动治疗支气管痉挛的给药装置，其特征在于：所述的药物瓶内放有具有一定压力的可雾化防痉挛药物，所述的药物为布地奈德气雾剂或特布他林气雾剂 。The above-mentioned drug delivery device for automatic treatment of bronchospasm by general anesthesia of the present invention is characterized in that: the drug bottle is filled with a nebulizable antispasmodic drug with a certain pressure, and the drug is budesonide aerosol or Terbutaline Aerosol.
上述本发明的全身麻醉自动治疗支气管痉挛的给药装置，其特征在于：所述气缸的活塞面积为气缸管面积的6-10倍。The above-mentioned drug delivery device for automatic treatment of bronchospasm by general anesthesia of the present invention is characterized in that: the piston area of the cylinder is 6-10 times the area of the cylinder tube.
上述本发明的全身麻醉自动治疗支气管痉挛的给药装置，其特征在于：所述的导药管上还设置有开关。The above-mentioned drug delivery device for automatic treatment of bronchospasm by general anesthesia according to the present invention is characterized in that a switch is also provided on the drug guiding tube.
本发明的装置的使用方法为：在手术时，药瓶内放有可以雾化的治疗痉挛疾病的药物，将导药管的一端插入药瓶内，打开开关。将螺旋管的端口固定在病人喉管处，开启麻醉机，麻醉剂与氧气的混合气体被送入病人体内。The use method of the device of the present invention is as follows: during the operation, the medicine bottle for treating spastic diseases is placed in the medicine bottle, one end of the medicine guiding tube is inserted into the medicine bottle, and the switch is turned on. The port of the spiral tube is fixed at the throat of the patient, the anesthesia machine is turned on, and the mixed gas of anesthesia and oxygen is sent into the patient's body.
在正常情况下，在弹簧的压力下，气缸轴上端的通孔位于导药管的下方，也就是通孔不与导药管相通，药物不能经导药管进入螺纹管内。Under normal circumstances, under the pressure of the spring, the through hole on the upper end of the cylinder shaft is located below the drug guiding tube, that is, the through hole is not connected with the drug guiding tube, and the medicine cannot enter the threaded tube through the drug guiding tube.
当病人出现呼吸道痉挛时，人体气管收缩，混合气体不能进入体内，螺纹管内的压力升高，气缸内的压力也随之升高，当气缸轴的力量大于弹簧的力量时，推动气缸活塞和气缸轴运动，使气缸轴上的通孔与导药管相通，药瓶内的气雾剂经导药管进入螺纹管内，再进入人体内，快速消除或缓解病人的气道痉挛。当病人不再痉挛时，螺纹管内的压力迅速下降，当气缸轴的力量小于弹簧的力量时，气缸轴回缩到原来的位置，气缸轴上的通孔不再与导药管相通，气缸轴将导药管堵塞。When the patient has airway spasm, the human trachea contracts, the mixed gas cannot enter the body, the pressure in the threaded pipe increases, and the pressure in the cylinder also increases. When the force of the cylinder shaft is greater than the force of the spring, the cylinder piston and the cylinder are pushed The shaft moves to make the through hole on the cylinder shaft communicate with the drug guiding tube, and the aerosol in the medicine bottle enters the threaded tube through the drug guiding tube, and then enters the human body to quickly eliminate or relieve the patient's airway spasm. When the patient no longer cramps, the pressure in the threaded tube drops rapidly. When the force of the cylinder shaft is less than the force of the spring, the cylinder shaft retracts to its original position, and the through hole on the cylinder shaft is no longer communicated with the drug catheter. Block the catheter.
所述气缸的活塞面积大于气缸管面积，可以在相同的压强下，增加气缸活塞的压力，有利于推动气缸轴运动。The piston area of the cylinder is larger than the cylinder tube area, which can increase the pressure of the cylinder piston under the same pressure, which is beneficial to push the cylinder shaft to move.
本发明选取布地奈德等可雾化的药物，当药物与混合气体（氧气和麻醉剂）混合后，通过进入体内，快速缓解痉挛反应，不影响手术的进行。The present invention selects nebulizable medicines such as budesonide, and when the medicine is mixed with mixed gas (oxygen and anesthetic), it enters the body to quickly relieve spasticity without affecting the operation.
本发明的有益效果是，在手术过程中，当发生气道痉挛发生时，可以自动给病人给药，快速消除或缓解病人的痉挛，使手术能顺利进行，防止病人窒息。The beneficial effect of the invention is that during the operation, when airway spasm occurs, the drug can be automatically administered to the patient, the spasm of the patient can be quickly eliminated or relieved, the operation can be carried out smoothly, and the patient can be prevented from suffocation.
