A kind of gravity venous transfusion acoustic transmission deviceTechnical field
The present invention relates to a kind of gravity venous transfusion acoustic transmission device, particularly a kind of transmitter for gathering and conduct sound wave in disposable gravity intravenous transfusion device dropping funnel.
Background technology
Along with the development of science and technology and improving constantly of people's living standard, the requirement of people to medical service level is more and more higher, current venous transfusion nursery work is also badly in need of improving, particularly transfusion nursing work occupies the service for life space of a large amount of human resourcess and hospital, makes service quality be difficult to improve; For improving this situation, this field is successively proposed multiple venous transfusion monitoring and managing method, up to the present a kind of design is not still had can to meet transfusion nursing demand completely, its main cause is that intravenous transfusion monitoring signals collecting is more difficult, the signal that existing method gathers is reliably not accurate enough, have impact on the general effect of monitoring nursing, it is very necessary for therefore developing new simple and reliable transfusion signal acquisition method.
Summary of the invention
The invention provides a kind of gravity venous transfusion acoustic transmission device, particularly a kind of transmitter for gathering and conduct sound wave in disposable gravity intravenous transfusion device dropping funnel, in order to achieve the above object, technical scheme of the present invention is achieved in that
Described gravity venous transfusion transmitter 1, it is made up of taper sound collecting tube 1-1, acoustic waveguide tube 1-2, mounting limit platform 1-3, shielding position-limiting cover 1-4, observation panel 1-5, position-limiting cover chamber 1-6 six positions; Its structural relation is: the sound collecting tube wide-mouth 1-1-1 of taper sound collecting tube 1-1 is positioned on the negative camber of shielding position-limiting cover 1-4, the corresponding position-limiting cover chamber 1-6 in center, the sound collecting tube slot 1-1-2 of taper sound collecting tube 1-1 is communicated with acoustic waveguide tube 1-2 one, the outer ring surface of taper sound collecting tube 1-1 is tapered, the termination transition of sound collecting tube slot 1-1-2 is mounting limit platform 1-3, and sound collecting tube wide-mouth 1-1-1 is connected as a single entity with shielding position-limiting cover 1-4; The outer ring surface tapering of acoustic waveguide tube 1-2 is less, and comparatively thick with one end of mounting limit platform 1-3 disjunctor, other end port is slightly thin; The outward appearance of shielding position-limiting cover 1-4 is overlooked as C shape, and side-looking in a tubular form; The opening of shielding position-limiting cover 1-4 is observation panel 1-5, and observation panel 1-5 is corresponding with the taper sound collecting tube 1-1 on shielding position-limiting cover 1-4 negative camber; Cavity in shielding position-limiting cover 1-4 is position-limiting cover chamber 1-6, and infusion unit titrimeter 2 is just in time stuck in the 1-6 of position-limiting cover chamber, the negative camber of shielding position-limiting cover 1-4 and the external annular surface of infusion unit titrimeter 2 seamless applying.

Beneficial effect
Gravity venous transfusion acoustic transmission device, for gathering and conducting the acoustic information in infusion unit titrimeter, can conduct to outside corollary system by the physical message producing and imply in dropping funnel in transfusion device work, make it further to be developed; Its good airproof performance, can shield filtering external noises, and structure is simple, and cost is little, and manufacturability is strong.
Detailed description of the invention
Gravity venous transfusion acoustic transmission device 1 is casting integrated, can injection moulding one-shot forming, and its profile adopts two points of split cavity molding, the negative camber of its shielding position-limiting cover 1-4, the pore of taper sound collecting tube 1-1, and the pore of acoustic waveguide tube 1-2 adopts line position to loose core injection mo(u)lding.
Gravity venous transfusion acoustic transmission device 1 provided by the present invention in the application, the shielding position-limiting cover 1-4 of gravity venous transfusion acoustic transmission device 1 is enclosed within the bottom medicinal liquid remaining portion of infusion unit titrimeter 2, the lucky sealing paste of sound collecting tube wide-mouth 1-1-1 is combined in the outer ring surface of infusion unit titrimeter 2, both can collect the acoustic information produced in infusion unit titrimeter 2, maskable falls the external noises of infusion unit titrimeter 2 again; Its acoustic waveguide tube 1-2 is communicated with outside corollary system by extension tube attached, and also directly can embed and be assembled in ambient systems, the relevant information gathered is conducted and is used to outside corollary system; Observation panel 1-5 can observe directly the amount of liquid medicine in infusion unit titrimeter 2.
