Problems solved by technology

[0003] The current nerve block drug injection device has the following disadvantages: 1. The puncture structure, the drug injection structure and the retraction structure before drug injection are set independently. Positioning operation, and the operation of withdrawal and injection requires the cooperation of assistants. On the one hand, there is a problem of personnel occupation. On the other hand, anesthesiologists and assistants only communicate verbally, which greatly affects the accuracy and efficiency of anesthesia operations. ;2. The negative pressure state of the withdrawal and the positive pressure state of the injection can only be judged by the physician's experience. Whether the negative pressure is unstable or the pressure is too high during the injection, there is a risk of increasing the patient's pain and anesthesia complications

Embodiment 1

[0022] Such as figure 1 As shown, a device for nerve block drug injection that is easy to be operated by a single person includes a base plate 1, a puncture needle 9, a withdrawal unit, and a drug injection unit. The base plate 1 is provided with a negative pressure display window 2, Positive pressure indicating window 16 and joint 8, the observation sides of the negative pressure indicating window 2 and the positive pressure indicating window 16 are made of transparent material, which is convenient for observing internal conditions, and the joint 8 and the puncture needle 9 are detachable connect. The negative pressure display window 2 and the positive pressure display window 16 are respectively provided with a negative pressure display diaphragm 4 and a positive pressure display diaphragm 17, and the negative pressure display diaphragm 4 and the positive pressure display diaphragm 17 are composed of Made of elastic material, such as a thin rubber layer, the negative pressur...

Embodiment 2

[0027] Compared with embodiment 1, the difference of this embodiment is: as image 3 As shown, the inner wall of the positive pressure injection chamber 15 is provided with a pressure regulating capsule layer 19, and a pressure regulating chamber is formed between the pressure regulating capsule layer 19 and the inner wall of the positive pressure injection chamber 15, and the pressure regulating capsule layer and the positive pressure A return spring 20 is arranged between the inner walls of the injection chamber. The pressure regulating chamber communicates with the outside world through an airflow duct 21 or an airflow hole. The pressure regulating bag layer is made of elastic material, such as a thin rubber layer. In the specific injection process, when the injection pressure is too high (excessive pressure can easily cause nerve damage), the liquid medicine squeezes the pressure-regulating capsule layer and overcomes the spring force of the return spring, causing the press...

Abstract

The invention discloses a device used for nerve blocking drug injection and convenient to operate by a single person. The device comprises a base plate, a puncture needle, a pumpback unit and a drug injection unit, wherein a negative pressure indicating structure, a positive pressure indicating structure and a connector are arranged on the base plate; the negative pressure indicating structure andthe positive pressure indicating structure communicate with the connector through a pumpback pipeline and a drug injection pipeline respectively; press type switches are arranged on the pumpback pipeline and the drug injection pipeline; and the pumpback unit and the drug injection unit communicate with the negative pressure indicating structure and the positive pressure indicating structure respectively. By the adoption of the device for nerve blocking anesthesia drug injection, on one hand, the puncture needle, the pumpback unit and the drug injection unit are integrated through the base plate, so that single-person nerve blocking operation is achieved, the labor cost is saved, and meanwhile the accuracy and efficiency of anesthesia operation are improved; and on the other hand, a negative pressure state and a positive pressure state can be accurately displayed through the pressure indicating structures, so that the pain of a patient and the risk of anesthesia complications are reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for nerve block injection that is convenient for single-person operation. Background technique [0002] Ultrasound technology has brought changes to many medical professions, and anesthesiology is no exception. In recent years, ultrasound technology has been increasingly used in various fields of anesthesiology, and has become the third eye of anesthesiologists. Ultrasound-guided peripheral nerve block The hysteresis significantly improves the accuracy of anesthesiologists' operations, avoids the pain caused by repeated blind detection of traditional operations, improves the success rate and safety of anesthesia operations, and realizes precise anesthesia, which significantly reduces the rate of general anesthesia and significantly reduces the cost of anesthesia drugs , in line with the two aspects of dual control and double reduction of medical institutions and comforta...
