Description

Fixing device for syringe drainage

Technical Field

The invention relates to the technical field of medical instruments, in particular to a fixing device for syringe drainage.

Background

The syringe negative pressure drainage is to utilize the principle of negative pressure suction to generate pressure lower than the atmospheric pressure at the wound surface to suck out the subcutaneous liquid of the wound surface. The disposable syringe negative pressure drainage is applied after plastic surgery, so that effective drainage can be maintained, the drainage liquid property can be conveniently observed, the drainage quantity can be accurately recorded, and the occurrence of complications such as skin flap necrosis, infection and the like can be reduced.

After an operation of an orthopedic patient, a disposable syringe is usually left for continuous negative pressure drainage, and a needle is usually arranged between the bottom of a syringe and a piston rod to support the piston rod clinically so as to fix the piston and ensure the negative pressure in the syringe. However, in the long-term fixing process, the needle is easy to fall off due to the movement of the patient or external reasons, so that the piston moves, and the negative pressure in the syringe cannot be kept. And because the length of the needle head can not be adjusted, the syringe can not meet the requirements of negative pressure suction in different degrees. In addition, the injector is fixed on the patient by using the paper breathable adhesive plaster clinically, but the adhesive plaster is not sticky due to long-time adhesion and turning over or getting out of bed of the patient, so that the danger of tube detachment is caused. Moreover, in the negative pressure drainage process, the effusion in the syringe is discharged at intervals, and the syringe is fixed on the patient body by using the adhesive plaster again after the effusion is discharged, so that the operation is troublesome, and the working efficiency of medical personnel is reduced.

Disclosure of Invention

The invention aims to provide a fixing device for syringe drainage, which solves the problem that a piston rod is not stably fixed due to the fact that a needle head is easy to fall off in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a fixing device is used in syringe drainage, which comprises a supporting fram, support frame one end is provided with the through-hole, be provided with in the support frame and place the board, it is provided with the standing groove on the board to place, all be provided with a plurality of draw-in grooves on the lateral wall of standing groove both sides, the draw-in groove top transversely is provided with the spout, the draw-in groove all communicates with the spout, it is provided with the slide to slide in the standing groove, the slide both ends are provided with can block into the pawl in the draw-in groove, one side that the through-hole was kept away from to the slide and place and be connected with the spring between the board other end, the slide opposite side is provided with the mounting hole.

The principle of the scheme is as follows:

the placing plate is used for placing an injector, the supporting frame is used for supporting the placing plate, the through hole is used for placing a guide pipe for drainage, the clamping jaw in the mounting hole is used for clamping a piston rod of the injector, the piston rod is connected with the sliding plate, the piston rod can be pulled through the sliding plate to realize negative pressure, and the pawl on the sliding plate is used for being clamped in the clamping groove to fix the piston rod. During actual use, the injector is placed in the placing groove on the placing plate, the piston rod of the injector is inserted into the mounting hole, gas in the air bag can be extruded into the air pipe when the piston rod is inserted, the gas pushes the slide rod in the air pipe to slide, and the slide rod pushes the clamping jaw to enable the clamping jaw to clamp the piston rod of the injector, so that the connection between the piston rod and the sliding plate is realized. After the fixation is finished, the sliding plate is driven to slide, so that the pawl on the sliding plate is clamped into the clamping groove on the side wall of the placing groove to fix the piston rod, and the syringe and the catheter are connected to finish the negative pressure. When the piston rod is released, the sliding plate is pushed upwards to enable the pawl on the sliding plate to slide into the sliding groove.

The beneficial effect of this scheme does:

1. through being connected the piston rod and the slide with the syringe, set up the pawl on the slide to set up the draw-in groove on the standing groove lateral wall, can accomplish the fixed of piston rod through going into the draw-in groove with the pawl card, compare and rely on the syringe needle to support tightly fixed piston rod between syringe and piston rod among the prior art, adopt this scheme fixed piston rod fixed more firm, can guarantee to last the negative pressure in the syringe.

2. Set up the mounting hole on the slide to set up the gasbag in the mounting hole, can extrude the gas in the gasbag to the trachea when the piston rod of syringe inserts in the mounting hole, utilize gas to promote the clamping jaw in order to press from both sides the piston rod of tight syringe, realize being connected of piston rod and slide from this, easy operation, and connect firmly.

3. The sliding plate can be released by upwards pushing the sliding plate to enable the pawl on the sliding plate to slide into the sliding groove from the clamping groove, so that the piston rod can be conveniently adjusted under different negative pressure drainage conditions.

Further, place the board middle part and articulate on the support frame, place and all be connected with the telescopic link between board both ends bottom and the support frame bottom, the through-hole below is provided with the blow off pipe. The one end that will place the board and be close to the through-hole is pressed downwards and is made to place the board and rotate, can make syringe and pipe break away from, then can realize the discharge of hydrops in the syringe with syringe and blow off pipe intercommunication. The whole process does not need to take down the syringe, the operation is simple, and the working efficiency of medical staff is improved.

Furthermore, a pressing plate which can be clamped into the through hole is arranged above the through hole in a sliding mode, and pull ropes are connected to the two ends of the pressing plate and one end, close to the through hole, of the placing plate. The pressing plate can be pulled through the pull rope when the placing plate rotates, so that the pressing plate presses the conduit in the through hole, and effusion in the conduit is prevented from overflowing after the conduit is separated from the injector.

Furthermore, the inner side of the clamping jaw is provided with anti-skid teeth. The anti-skidding teeth can increase the friction between the clamping jaw and the piston rod, so that the piston rod is fixed more stably.

Furthermore, an elastic band is connected to the side wall of one side of the support frame, and a connecting piece is connected between the other end of the elastic band and the side wall of the other side of the support frame. Through twine the elastic cord on the patient body to utilize the connecting piece to connect the elastic cord on the support frame, so can fix whole device on the patient body, the patient of being convenient for gets off the bed activity during negative pressure drainage.

Furthermore, an elastic piece is arranged on the side wall of the placing groove. Can extrude the elastic component on the standing groove lateral wall when the standing groove is placed to the syringe, the elastic component can utilize the elastic restoring force of self to support tight syringe for placing that the syringe can be more firm in the standing groove.
