[0027] In the description of the present utility model, it should be noted that the terminology nouns in the various embodiments, such as words indicating directions such as "upper", "lower", "front", "back", "left", "right", etc., are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the referred elements and devices must be operated according to the specific directions and specified operations and methods and structures in the specification. Such directional nouns do not constitute limitations on the present utility model.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Specific implementation plan 1: Combine Figures 1 to 4 As shown, the utility model provides an adjustable drainage device for anesthesia site, including a catheter 2 and a puncture needle 1, wherein the puncture needle 1 is provided at one end of the catheter 2, an anesthesia area is provided in the middle of the catheter 2, and the anesthesia area is used to place anesthetic drugs, and a drainage area 4 is provided at the lower end of the catheter 2, and the drainage area 4 includes a plurality of through holes arranged on the catheter 2, which are used to discharge the liquid in the cavity through the through holes.

[0030] When in use, the part requiring puncture and drainage is first subjected to routine disinfection, paved with sterile towels, and local infiltration anesthesia. The skin is pierced at the puncture site with a pointed surgical blade, and then the puncture needle 1 is obliquely punctured from the skin rupture. The puncture needle 1 enters the cavity until the anesthesia area and the drainage area 4 are both located in the skin. Local anesthesia is performed by the anesthetic in the anesthesia area, which reduces the pain caused by the patient during drainage, and effectively reduces the pain and discomfort of the patient during the intubation process and the use process. The dosage of the anesthetic used here needs to be determined according to the doctor's advice; the puncture needle 1 is pulled out from the cavity and blocked with a blocking block such as a rubber plug. The drainage area 4 is provided with a through hole to introduce the body fluid into the catheter 2 and then discharge it, thereby reducing the possibility of the drainage hole being blocked due to the change of the contact position of the drainage tube in the body. The provision of multiple through holes can increase the drainage speed compared to drainage only through the end of the drainage tube.

[0031] Specific implementation plan 2: Combined Figures 1 to 4 As shown, the anesthesia area can be an anesthesia coating 3 for carrying anesthetic drugs. When the drainage tube is inserted into the body, the anesthetic drugs on the anesthesia coating 3 are slowly released and take effect under the action of body fluids, thereby reducing the pain of the patient. The other combinations and connection relationships of this embodiment are the same as those of the specific embodiment 1.

[0032] Preferably, the length of the anesthetic coating 3 is 2 cm-3 cm, and the thickness of the anesthetic coating 3 is 2 mm-5 mm.

[0033] Specific implementation plan three: Combined Figures 1 to 4 As shown, the anesthesia area may be an anesthesia cannula 5, which is arranged outside the catheter 2, and the side wall of the anesthesia cannula 5 is in a hollow state, and a plurality of penetration holes 7 are arranged on the outer wall of the anesthesia cannula 5. It is used to fill the inner wall of the anesthesia cannula 5 with anesthetic drugs, and perform local anesthesia through the slow penetration of the penetration holes 7. The other combinations and connection relationships of this embodiment are the same as those of the specific embodiment 1.

[0034] Preferably, an anesthetic drug introduction tube 6 may also be included, wherein the anesthetic drug introduction tube 6 is located inside the catheter 2 and one end of the anesthetic drug introduction tube 6 penetrates the side wall of the catheter 2 and is connected to the inner wall of the anesthesia sleeve 5, and the other end of the anesthetic drug introduction tube 6 is located outside the catheter 2, and the anesthetic drug can be introduced into the anesthesia sleeve 5 through the anesthetic drug introduction tube 6 and seeps out through the permeation hole 7. This solution can be used for patients who need long-term drainage, and the intake of anesthetic drugs can be supplemented according to the patient's condition.

[0035] The types and dosages of anesthetic drugs used in this plan must comply with the standards for anesthesia injection and must be administered based on the orders of an anesthesia technician.

[0036] Preferably, a spring may be provided in the catheter 2 to support the catheter 2 to prevent the patient from compressing the catheter 2 and affecting the drainage. The provision of the spring can make the catheter 2 more susceptible to stress, making it easier to adjust the insertion depth or angle of the puncture needle 1 when it is inserted.

[0037] Preferably, the catheter 2 is an anticoagulant catheter 2, which is used to prevent blood coagulation caused by bleeding during intubation and blockage of the drainage tube.

[0038] Preferably, a scale is provided on the outer wall of the catheter 2 to facilitate observation of the depth to which the drainage tube has entered.

[0039] Preferably, combined Figure 5 As shown, the puncture needle protection cap 8 is also included. The puncture needle protection cap 8 can be sleeved on the catheter 2 to protect the puncture needle 1 from hurting the patient.

[0040] Preferably, the puncture needle protection cap 8 is detachably connected to the outer wall of the catheter 2 via threads.

[0041] Preferably, a plurality of buckles 9 inclined in the opposite direction to the puncture needle 1 are provided on the outer wall of the catheter 2 below the puncture needle 1, and the buckles 9 are rubber buckles. A buckle boss matching the shape of the buckle 9 is provided at the opening of the puncture needle protective cap 8. The puncture needle protective cap 8 can be buckled onto the catheter 2 in the direction of the drainage area 4 in this cavity. The buckle 9 in contact with the buckle boss is slightly deformed, which facilitates the insertion of the puncture needle protective cap 8. However, when the puncture needle protective cap 8 moves in the opposite direction, the shape of the buckle 9 prevents the puncture needle protective cap 8 from being removed, which is used to prevent the puncture needle 1 from injuring the patient after puncture. The puncture needle 1 does not need to be pulled out in this cavity, which avoids the tissue fluid filled in this cavity from wrapping the puncture needle 1, and the force point is small, making it difficult to remove the puncture needle.

[0042] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art of the utility model may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
