A tri-ring syringe which includes a barrel () having a distal end and a proximal end. The proximal end of the barrel () is provided with a double ring handle. The syringe also includes a plunger () including a distal end and a proximal end, the proximal end of the plunger () being provided with a single ring handle (), the distal end of the plunger () connecting with a rubber stopper () and being inserted into the interior of the barrel (); and an insertion part () connected to the barrel () and rotating synchronously with the barrel. The invention allows the torque of the rotation of the barrel () to be transmitted outward.

Tri-ring syringe

A balloon pressure pump comprising a cavity () having a distal end and a proximal end; a push rod () having a distal end and a proximal end, and provided with an external thread and inserted into the cavity; a handle () fixedly connected with the proximal end of the push rod (); a locking member () having a distal end and a proximal end and arranged on the proximal end of the push rod () and used to lock same; the distal end of the locking member () is fixedly connected with the proximal end of the cavity (). The handle () is internally provided with a sleeve () to accommodate the push rod (); said sleeve () is fixedly connected with the proximal end of the locking member (). The proximal end of the push rod () includes a spring () which is enclosed within the sleeve. The simple structure of the pump simplifies operations such as pressure application, pressure relief, negative pressure evacuation and the like, and is greatly convenient for a user.

Balloon pressure pump

A triple three-way valve device comprises: a valve body () having a distal end and a proximal end, wherein the proximal end of the valve body () is connected with a control knob () that is radially rotatable relative to the valve body (); and a valve rod () having a distal end and a proximal end, wherein the valve rod () is provided within the valve body () and is fixedly connected with the control knob (). The distal end of the valve body () is connected with a seat body (), which is connected with a plurality of liquid passages and a high pressure pipe passage; a selection member () provided at the distal end of the valve body (), wherein, depending on the position of the control knob (), the selection member () selects the communication relationships between the plurality of liquid passages of the seat body (), the high pressure pipe passage and the valve rod. With the triple three-way valve device, angiocardiography surgery is simplified, and surgery safety and efficiency are improved.

Manifold valve device

A rotary medical manifold, for delivering various fluids through a patient delivery mechanism is described. The rotary manifold can include a manifold body and a valve stem. The manifold body can include a central cavity, an output port, a first fluid port, and a second fluid port. The valve stem can include an injector port, and a single central fluid passage. The valve stem can be adapted to slidably engage the central cavity of the manifold body and provide selective fluidic connectivity between the injector port and the output port, the first fluid port and the second fluid port.

Rotary medical manifold

A locking syringe with an integrated bias member, for delivering medical fluids at high pressure, can include a housing, a shaft, a piston, a cap assembly, a bias member, and a locking member. A distal end of the housing can interface with a patient delivery apparatus. A piston can be connected to the distal end of the shaft and can include a peripheral sealing surface that can slidably engage the inside surface of the housing to form a movable seal. The cap assembly at the proximal end of the housing can engage the shaft. A base cap can secure the piston within the housing. The bias member can have a distal end coupled to the piston and a proximal end restrained, such as to help pressurize the internal cavity. The user-actuatable locking member can user-selectively engage and inhibit unwanted movement of the shaft.
