Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a pre-filled surface anesthesia device for bronchoscopic examination. Background Art
[0002] Bronchoscopy is a widely performed procedure in clinical practice and is of great significance in the diagnosis and treatment of respiratory diseases. It is mainly performed by inserting a slender bronchoscope into the patient's lower respiratory tract through the mouth or nose, that is, passing through the glottis into the trachea and bronchi and further distally, directly observing the lesions of the trachea and bronchi, and performing corresponding examinations and treatments based on the lesions. When performing bronchial examinations, the patient needs to be anesthetized to ensure that the patient does not feel pain or discomfort during the examination. At present, there are three main anesthesia techniques used in electronic bronchoscopy technology: local anesthesia, local anesthesia combined with intravenous sedation and analgesia (the so-called painless bronchial endoscopic technology) and general anesthesia. Currently, the vast majority of patients undergo electronic bronchoscopy under local anesthesia. The drug used for local anesthesia is mainly lidocaine, but most of the existing anesthetic drugs are stored in ampoules, and the injection specification of a general ampoules is 5ml, while the amount of anesthetic drug required for local anesthesia is about 20-30ml. It is necessary to manually break 4-5 ampoules and then use a syringe to manually draw out the drug solution again and again, which is time-consuming and labor-intensive. In addition, when medical staff break the ampoules, there are risks of broken glass of the ampoules, loss of drug solution, medical staff being scratched by glass and needle injuries, and increased nosocomial infection. Utility Model Content
[0003] The utility model aims to provide a pre-filled surface anesthesia device for bronchoscopy which is simple to operate, saves time and effort and has high safety, so as to solve the technical problems in the prior art that when performing anesthesia, multiple ampoules need to be broken and then drawn out, which is time-consuming and labor-intensive, and the glass of the ampoules is easily broken, scratching medical staff and causing loss of liquid medicine.
[0004] In order to solve the above technical problems, the solution adopted by the utility model is as follows:
[0005] A prefilled surface anesthesia device for bronchoscopy, comprising an outer sleeve, a piston, a core rod, a conical joint, a core rod handle and a clamp; the bottom end of the core rod is fixedly connected to the piston, and the top end is fixedly connected to the core rod handle; a solution cavity is provided in the outer sleeve; the piston is located in the solution cavity, and the volume of the solution cavity is 5-30 ml; the bottom end of the outer sleeve is fixedly connected to the conical joint; wing handles are provided on both sides of the upper end of the outer sleeve. The wing handle provides a support when the medical staff pushes the anesthetic, making it convenient for the medical staff to press the core rod handle and move the piston; the clamp is in a "concave" shape, with the lower end clamped on the outer sleeve and the upper end against the core rod handle; the clamp is limited by the wing handles on both sides of the outer sleeve to prevent the piston from pushing the anesthetic out of the solution chamber due to external force pressing the core rod handle during transportation; the solution chamber is provided with anesthetic, and the core rod is pushed by the core rod handle to drive the piston to move in the solution chamber, pushing the anesthetic from the opening of the conical joint into the operation hole of the bronchoscope; the outlet at the bottom end of the conical joint is spherical and is provided with a matching sealing cover.
[0006] Furthermore, the clamp is composed of two arc-shaped clamps A; the clamp A is provided with a clamp B; the clamp A is provided with a clamp slot matching the wing handle; the bottom end of the clamp B is fixedly connected to the clamp A, and the top end is against the core rod handle; the two clamps A are mutually engaged through clamp teeth, or are fixed by winding with a fixing belt. The clamp slots of the two clamps A are respectively sleeved on the wing handles on both sides of the jacket, and are combined and connected into an integral clamp, the top end of the clamp B is against the core rod handle, and the core rod and the core rod handle are fixed and limited by the clamp A and the clamp B. The design of the clamp A and the clamp B is convenient for medical staff to remove the clamp from the device when using the device and push the anesthetic in the device.
[0007] Furthermore, a groove for winding a fixing belt is provided on the card block B. The fixing belt is a wire or a plastic tie, and the fixing belt is wound on the groove of the card block B to wind and fix the card block A.
[0008] Furthermore, the diameter of the spherical outlet of the conical joint is 4 mm, and the diameter of the inner wall of the outlet is 1.5 mm. The spherical outlet with a diameter of 4 mm is larger than the end of the pipeline of a general intravenous catheter, which avoids the phenomenon of mistaken insertion of the intravenous infusion catheter and facilitates the insertion of the fiberoptic bronchoscope operation hole to anesthetize the patient.
[0009] Furthermore, the anesthetic is lidocaine injection; air is provided between the lidocaine injection in the solution chamber and the piston. The piston pushes the gas to completely push the lidocaine injection in the solution chamber out, thereby avoiding drug waste and improving drug utilization.
[0010] The working principle of the utility model is as follows:
[0011] When in use, the medical staff cuts the fixing belt in the groove on the block B of the card or pries open the teeth on the block A, removes the blocks A and B from the wing handles on both sides of the outer sleeve, releases the limit of the core rod handle on the card, and then removes the sealing cover of the conical joint, inserts the spherical opening into the operating hole of the bronchoscope, presses the index finger and middle finger of the medical staff under the wing handle, presses the core rod handle with the thumb, and drives the piston at the bottom of the core rod to move through the core rod handle. The piston pushes the air and pushes the lidocaine injection from the opening of the conical joint into the operating hole of the bronchoscope to anesthetize the patient.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. The utility model directly fills the anesthetic in the solution cavity, and the core rod handle pushes the core rod to drive the piston into the solution cavity and press downward to push the anesthetic into the operation hole of the bronchoscope through the outlet of the conical opening to anesthetize the patient, thereby reducing the time for drug preparation, alleviating the workload of medical staff and improving work efficiency, reducing the risk of scratches and needlesticks for medical staff, and hospital infection during drug preparation. The overall operation is simple, saving time and effort.
[0014] 2. The clamp of the utility model can limit and fix the core rod handle to avoid the phenomenon that the piston pushes the anesthetic out of the solution chamber due to external force pressing the core rod handle during transportation. The two arc-shaped clamping blocks A of the clamp are engaged with each other or fixed with a fixing belt, which is convenient for medical staff to remove the clamp from the device.
[0015] 3. The solution chamber of the utility model is filled with air, and the piston pushes the air to completely push the anesthetic out of the solution chamber, thereby avoiding drug waste and improving the utilization rate of the drug.
[0016] 4. The outlet of the conical connector of the utility model is spherical, and its diameter is larger than the end of the pipeline of a general intravenous catheter, which can effectively avoid the phenomenon of injecting anesthetic into the intravenous channel due to misoperation.
