Things To Remember Before Buying Suction Pumps

There has been an influx in the manufacture of suction pumps for the last few years as its popularity lies in its simplicity and easy handling. Almost every other month, most hospitals are brooding over the better model to buy, and it is an endless hunt, as suction pumps have been designed to effectively solve the problem in the minimum time required.

What are Suction Pumps?

A suction pump is just a common pump in which the liquid that is given is raised into a partial vacuum by means of atmospheric pressure through a valve piston meant for retreating on an upstroke and a check valve present in the pipe prevent reflux.

Suction Pumps

Medical Suction Pump is used to inspect a variety of diseases. It is widely used in cases to clean the trachea of blood, vomit, saliva and such secretions to allow the patient to breathe. It may also be used to suck out the mucus from stomach and intestines. High-grade suction pumps may also be used in endoscopy chambers for suction, during vacuum-assisted cesarean delivery and cleaning wounds.

Since choosing the right surgical pump is a tough decision, this article has discussed the wide range of pumps available and how to select them based on accuracy, prevention of fluid slip (migration of fluids around the moving parts such as gear, lobe and vane pumps).

Which Ones to Choose?

To begin with, syringe pumps should be chosen over ceramic displacement pumps. This is because Syringe pumps are ideally designed for the process of aspirating precisely along with the dispensation of reagents and samples. They are frequently used in IVD and analytical instruments. A primitive syringe pump that uses a glass cask having a kind of plunger, that’s Teflon, as a syringe is used to navigate the fluid. Its advantage is, it is replaceable easily and enables the changing of syringe sizes to facilitate multiple volumes.

A ceramic pump, in contrast, has the mechanism of one motor that uses a piston made of ceramics internally located for the aspiration and dispensation of liquids. The disadvantage of this instrument lies in the fact that it is not easily replaceable and a set of multiple pumps performing particular functions are to be required in it. Rotary displacements pumps and Linear Pumps are at par with each other. But the difference lies in the fact that rotary pumps use faster dispensing mechanism than linear pumps. In rotary pumps, rotary valuing motions and linear displacement motions work simultaneously.

Things to Remember Before Buying a Suction Pump:

Minimization of Fluid Slip: The factors that determine slip rate are time, pressure and viscosity. A slip wouldn’t be a big factor when there will be constant liquid viscosity and pressure, in a rate pump, that has high repetition, is quite high, rather than through a low rate of repetition pump. So, to reduce slip of the fluid, the reservoir height and the height of the tip ought to be equal, and the position of the tip, as well as the reservoir, should be optimum as it determines the lines of input and the lines of output of the fluid and observes fluid movement when not in use. So, application testing is important. It is always recommended to test the fluid or a placebo before selecting the pump.

Cycle Time: In case of rotary pumps, the cycle time and the capacity to generate a constant flow rate are the perks. Because of its mechanized dispense profile; it has the exclusive advantage of darting off small volumes of fluid in a quicker manner. Taking the example of such a mechanism, the cycle time of pumps should be prioritized.

Portability: The feature of portability makes a medical pump most beneficial because it meets emergencies. They should be portable enough to be placed in endoscopic towers, on the bedside of the patient and in OTs, having mobile suction units.

Reusable or Disposable System: To avoid unnecessary expenses over daily situations, reusability of units must be ensured. Also, in cases of accidents, the disposable system must be present.

Speed Regulation: In cases of vacuum-assisted delivery, there must be a highly mechanized and sensitive regulation system that can effectively control the suction rate when cups are attached to the baby’s head.

Suction Pumps

Simplicity: Simplicity is always preferred besides advanced mechanism, for rapid and effective results. So the mechanism must not be complicated that might turn result in time consumption and prove to be disadvantageous. Quick set up should also be ensured.

Aesthetically Pleasing: Smooth finishing and aesthetically appealing model is an added pleasure and even a must condition to ensure steady portability.

Choosing the accurate suction pump lies in the proper understanding of the application and mechanism. This article aims at resolving the confusions regarding the choices from the buyer’s side.
