Embodiment 1

[0036] In order to solve the problem that the existing syringe has only one needle seat, the inconvenience caused by the need to pull out and insert the needle many times during use, and the problem that bacterial infection is prone to occur, the present invention provides a figure 1 , figure 2 , image 3 , Figure 4 The multifunctional combined double-barreled syringe shown includes a syringe 1, a needle seat 7 arranged at the top of the syringe 1, a stem 3 arranged at the bottom of the syringe 1, and one end of the stem 3 is placed in the syringe 1 , the other end is placed outside the syringe 1, and is connected with the baffle 6, and also includes the second syringe 2, the second needle seat 9 arranged on the top of the second syringe 2 is arranged on the second needle seat 9 at the bottom of the second syringe 2 Core rod 4, one end of the second core rod 3 is placed in the second syringe 2, the other end is placed outside the syringe 1, and a second baffle 8 is connect...

Embodiment 2

[0043]On the basis of Embodiment 1, the automatic pressure check valve 15 is not provided on the Y-shaped infusion tube 14, but the automatic pressure one-way valve 15 is arranged on other medical instruments connected with the Y-shaped infusion tube 14, like this The flexible use of the automatic pressure one-way valve 15 and the multifunctional combined double barrel syringe can be realized.

[0044] Above-mentioned Y type transfusion tube 14 is connected as Figure 7 The infusion tube 21 is shown, and the infusion tube 21 is provided with an automatic pressure check valve 15 . In this way, the first branch liquid channel 16 of the multi-functional combination double-barrel syringe can be connected with the injection needle 24 when rescuing the patient, and the second branch liquid channel 17 can be connected with the infusion tube 21, so that the effusion in the patient can be extracted without repeatedly pulling out the needle and inserting it. The needle is used to compl...

Embodiment 3

[0050] The first branch liquid channel 16 or the second branch liquid channel 17 of the above-mentioned Y-shaped infusion tube 14 is connected to a Y-shaped infusion tube 14 to form a multi-functional combined double-barreled syringe with three channels, and then combined and connected to Example 2 The medical appliance will have a greater expansion of the various applications described in Embodiment 2.

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and particularly relates to a multifunctional combined double-tube syringe which comprises two needle tubes. Two types of liquid can be sucked in sequence and injected several times, and injection can be conducted without frequently pulling and inserting needles. Functions such as circulating injection, sterile liquid separation, rapid blood transfusion, circulating hydrops drawing and the like can be achieved after the multifunctional combined double-tube syringe is connected with a self-control pressure check valve, the problem of bacterial infection caused by frequent needle inserting and pulling is avoided, pain of patients is reduced, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional combined double-barreled syringe. Background technique [0002] Syringes are a common medical appliance. As early as the 15th century, Italian Catinel proposed the principle of syringes. Mainly used for injecting liquid medicine or drawing liquid. Syringes are also used in medical equipment, containers, and scientific instruments such as some chromatography to inject through a rubber septum. Injecting gas into a blood vessel can cause an air embolism. The way to remove air from the syringe to avoid embolism is to invert the syringe, tap it gently, and squeeze out a little fluid before injecting into the bloodstream. [0003] The syringes currently used in medical equipment are all piston-type syringes. Liquid is fed in when the piston is drawn, and liquid is discharged when the piston is pushed, and a needle seat is provided. This type of ...
