Abstract
The utility model relates to a continuous microscale syringe which is an appliance used for slowly and continuously injecting physic liquor into a patient. The utility model comprises an outer shell 1, a cover 7, a core post 4, a capsule 2, a flexible pipe 13 and an interface of an injection needle 9, wherein, a current limiting block 12 made of poromerics is arranged in a liquid outlet hole 11 on the core post. A one-way valve 8 is arranged in a liquid feeding hole 6. Physic liquor is fed from the liquid feeding hole to enter the capsule, and the capsule is braced to be large. Through the elasticity of the capsule, the physic liquor is slowly injected into a human body through the liquid outlet hole, the current limiting block, the flexible pipe, the interface of the injection needle, and the injection needle connected with the interface, and the purpose that the physic liquor is slowly injected can be obtained.
Description
This utility model relates to and a kind ofly slowly continues the utensil of fluid injection to patient, and a kind of trace continues impregnator.
Postoperative patient or cancer patient need be injected analgesic drug product at si dol urg, and this analgesic drug product needs slowly and constantly to inject.
The purpose of this utility model is exactly to propose a kind of utensil that can continue to carry out micro-fluid injection to patient.
This trace continues impregnator and comprises shell, lid, stem stem, capsule, flexible pipe and entry needle interface, capsule set is outside stem stem, lid is passed in the upper end of stem stem, and fix with lid, lid is enclosed within the upper end of shell, stem stem and capsule stretch in the shell, there is a liquid filling hole stem stem front portion, the outlet of this liquid filling hole is in the capsule, and a liquid outlet is arranged on the stem stem in addition, and the import of liquid outlet is in the capsule, the outlet of liquid outlet is connected with flexible pipe, the entry needle interface links to each other with the other end of flexible pipe, and the current limliting piece of a poromerics is arranged in the liquid outlet, and a check valve is arranged in the liquid filling hole.
This trace continues impregnator, and behind liquid filling hole adding medicinal liquid, medicinal liquid enters in the capsule, capsule is stretched, rely on capsular elasticity, medicinal liquid by liquid outlet, current limliting piece, flexible pipe, entry needle interface and be connected entry needle on the interface, is injected in the human body.The metering function of the current limliting piece that the dependence poromerics is made, the speed of injection is very slow, reaches lasting aim of alleviating pain.
Accompanying drawing 1 is the overall structure figure that this trace continues impregnator;
Accompanying drawing 2 is the structure chart of stem stem;
Accompanying drawing 3 is the structure chart of entry needle interface.
As shown in Figure 1, this micro-continuous injection device comprises shell 1, lid 7, stem stem 4, capsule 2, flexible pipe 13 and entry needle interface 9.Capsule 2 is enclosed within outside the stem stem 4, and the upper end of stem stem is passed lid 7 and fixed with it, and lid is enclosed within the upper end of shell 1, and fixes with it.Stem stem and capsule stretch in the shell, and there is liquid filling hole 6 the stem stem front portion, and the outlet 5 of liquid filling hole is in the capsule, and a check valve 8 is arranged in the liquid filling hole, and the medicinal liquid that guarantees to add in the capsule can oppositely not flow out from liquid filling hole.One liquid outlet 11 is arranged on the stem stem in addition, and the import 10 of this liquid outlet is in the capsule, and medicinal liquid injects in the human body by liquid outlet 11, flexible pipe 13 and entry needle interface 9 and top entry needle thereof.One current limliting piece 12 is arranged in the liquid outlet 11, make, medicinal liquid is carried out blood pressure lowering and current limliting by poromerics.
As shown in Figure 2, the check valve in the liquid filling hole 6 on the stem stem 4 of the lasting impregnator of this trace also can be to be in one section spring-backed quill 14 that the stem stem liquid filling hole exports 5 places, and the stem stem in liquid filling hole exit has an annular depressed portions 15.Above-mentioned spring-backed quill 14 is stuck in the above-mentioned annular depressed portions.Rely on the elasticity of spring-backed quill, the outlet 5 of liquid filling hole is sealed.Medicinal liquid can only flow in the capsule from liquid filling hole, and can not reverse flow.Some projectioies 3 can also be arranged, so that medicinal liquid adds and fashionable capsule strutted on the bottom outer wall of stem stem.
As shown in Figure 3, the current limliting piece 16 of a poromerics can be arranged also in the entry needle interface 9 of the lasting impregnator of this trace, such structure can make the process of fluid injection slow more and steady.
