Description

Technical Field

[0001] The utility model relates to the technical field of medical drug delivery catheters, in particular to a cross-head nerve block anesthetic drug delivery catheter. Background Art

[0002] Anesthesia surgery refers to giving patients certain drugs during surgery to make them painless, unconscious, and amnesic, and to ensure that their vital signs are stable. There are many types of anesthesia. In order to achieve more precise, safer, and more effective anesthesia effects, it is usually necessary to use a combination of anesthesia. Combining different types of anesthetic drugs and techniques can act on pain conduction pathways at different levels at the same time. This includes using local anesthesia techniques to anesthetize the surgical area and reduce the pain sensation in the surgical area, while using general anesthetic drugs to put the patient in an unconscious state and block the transmission of pain signals to the brain, which can achieve better pain control and relieve the patient's pain; it can be personalized according to the needs of the specific surgery and the characteristics of the patient, which can improve the effect of anesthesia and reduce the side effects and risks of using a single anesthetic drug. Compound anesthesia can also be flexibly adjusted according to the different stages and needs of the surgery to ensure that the patient is in a stable and safe state of anesthesia during the operation; compound anesthesia can provide better surgical conditions and control, allowing surgeons to operate better.

[0003] However, in combined anesthesia surgery, since different catheters are required to deliver anesthetic drugs in a short period of time in different layers and sequences during the operation, the surgeon is highly focused on the patient during the operation. During the intubation, the anesthetic drug delivery catheter may be inserted into the wrong drug delivery catheter, resulting in the mis-injection of anesthetics, improper anesthesia depth, and even allergic reactions.

[0004] In summary, a cross-head nerve block anesthetic drug delivery catheter needs to be designed to adapt to the injection of multiple anesthetics for combined anesthesia, and connectors are set between the catheters to avoid different types of anesthetics being mistakenly injected into the wrong anesthetic catheter.

The color is used to warn medical staff to prevent the mis-injection of anesthetic drugs.

[0031] Example 2

[0032] like Figure 2 The figure shows a schematic diagram of the structure of the connector 3 of the utility model. In the utility model, a connector 3 is provided, and the connector 3 includes a plug 302, a connector 301, and a pressure plate 6. The connector 301 is a hollow cylinder 3021 as a whole, and a thread is provided on the upper inner wall, and an annular baffle 3014 is provided on the middle inner wall. A sealing plate 3013 is provided at the lower end of the baffle.

[0035] Different diameter joints 301 are provided, and the joints 301 include a plug 302, a joint 301, and a pressing plate 6. The pressing plate 6 is pressed by rotating the joint 301 to drive the lower end of the U-shaped connecting rod 7 to contact the locking of the sealing plate 3013. The top column at the front end of the plug 302 presses the sealing plate 3013 to push the sealing plate 3013 open, and the sealing of the contact joint 301 is closed. The anesthetic drug can be delivered to the catheter 2 along the drug delivery tube through the joint 301 to inject the drug into the patient's body. The joint 301 provided in the utility model can only be assembled to form a complete joint with the plug 302 and the joint 301 of the same diameter. Head 301, if the diameter of the plug 302 does not match that of the connector 301, when the diameter of the plug 302 is larger than that of the connector 301, the plug 302 cannot be screwed into the connector 301; when the diameter of the plug 302 is smaller than that of the connector 301, it cannot be screwed in and can only be inserted, and the plug 302 cannot press on the pressure plate 6 in the mounting groove on the inner wall of the connector 301, or can only press on one side of the pressure plate 6, and cannot contact the restriction of the pressure plate 6 on the sealing plate 3013.
