Summary of the invention
Use the end that exists in order to overcome above-mentioned common stethoscope at lazaretto ward, the purpose of this utility model provides the special-purpose stethoscope of a kind of lazaretto ward, and it can prevent the infected sick chance that infects of doctor with having.
The technical solution of the utility model is the special-purpose stethoscope of this kind lazaretto ward, and it comprises ear piece, and conduit and body spare is characterized in that also being provided with between ear piece and conduit and patch connector.
Further program of the utility model is that described connector is the connection tube of TBE (threaded both ends), and the inner sleeve on one end and the ear piece is fastenedly connected, and the other end and supravasal interpolation pipe are fastenedly connected.This kind mode, simple in structure, but troublesome poeration.
Further program of the utility model can also be that connector comprises shell, trocar sheath, and intubate, ball, spring, movable inner sleeve is led spring, inner sleeve and back-up ring; Intubate one end connects with conduit, and its other end outer wall is provided with annular groove; Trocar sheath one end outer wall is a boss, its inwall and inner sleeve thread connection, and inner sleeve connects with ear piece; From the trocar sheath end of thread, in trocar sheath, be provided with successively compression lead spring, with the airtight movable inner sleeve of trocar sheath internal chamber wall, the intubate that end face cooperates with movable inner sleeve end face; Trocar sheath and the corresponding tube wall of intubate annular groove are provided with circular hole, and the circular hole outside diameter is greater than the ball diameter, and the ball diameter is greater than the circular hole inside diameter, and ball places in the circular hole; The trocar sheath other end is established the annular stop groove, card one back-up ring in the groove, and the outer wall of trocar sheath boss inboard overlaps a spring; Shell is enclosed within on the trocar sheath, and the diameter of step I is greater than the diameter of trocar sheath boss in the inwall of shell one end, and the distance in its other end inwall between step II and the trocar sheath outer wall is greater than the distance between outer sleeve inner wall and the annular groove bottom.This kind mode is pegged graft conveniently.
The special-purpose stethoscope of lazaretto ward is stronger deadly infectious disease Fang doctors such as the atypical pneumonia design of infectiousness specially.This design is to have designed a connector between common ear piece and body spare connecting duct, by connector can make easily two parts from.Connecting duct that connector is following and body spare can make easily two parts from, following connecting duct and the body spare of connector can be disposable products, also can be through the reusable product of sterilizing.
The beneficial effects of the utility model are: because stethoscopic body spare can separate with ear piece, ear piece need not be taken in the ward, remain the good isolation of protective garment, make the doctor not by pathogenic bacteria and viral infection, be particularly suitable for this control doctor who passes through the infectious disease of air droplet transmission of SARS and use.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is this utility model structural representation;
Fig. 2 is the longitudinal sectional drawing of connector.
Among the figure: 1 connector, 2 ear pieces, 3 conduits, 4 body spares, 11 shells, 12 trocar sheaths, 13 intubate, 14 circular holes, 15 balls, 16 springs, 17 movable inner sleeves, 18 lead spring, 19 inner sleeves, 20 back-up rings, 21 annular grooves, 22 limited impressions, 23 trocar sheath boss, 24 interior step I, 25 interior step II.
The specific embodiment
Shown in Figure 1.Overall structure of the present utility model is: it is by ear piece 2, and body spare 4, connector 1 and conduit 3 are formed.Connector 1 comprises shell 11, trocar sheath 12, intubate 13, ball 15, spring 16, movable inner sleeve 17, leads parts such as spring 18, inner sleeve 19 and back-up ring 20.Ear piece 2, body spare 4 and conduit 3 are same as the prior art.
Among Fig. 2, connector structure of the present utility model is: intubate 13 1 ends and conduit 3 sealed attachment, its other end outer wall is provided with annular groove 21.Trocar sheath 12 1 end outer walls are trocar sheath boss 23, and its inwall connects with inner sleeve 19 thread seals, inner sleeve and ear piece sealed attachment.From trocar sheath 12 ends of thread, in trocar sheath 12, be provided with compression successively and lead spring 18, movable inner sleeve 17, the intubate 13 that end face cooperates with movable inner sleeve 17 end faces with the sealing of trocar sheath internal chamber wall, external diameter equates with external diameter in the intubate in the movable inner sleeve; Trocar sheath 12 is provided with circular hole 14 with intubate annular groove 21 corresponding tube walls.Annular groove 21 is provided with 3-4 circular hole 14 perpendicular to the same plane of tubular axis line, and ball 15 is arranged in the circular hole 14, and circular hole 14 is tapered, and circular hole 14 outside diameter are greater than ball 15 diameters, and ball 15 diameters are greater than circular hole 14 inside diameter, and ball 15 places in the circular hole 14; Trocar sheath 12 other ends are established annular stop groove 22, and card one back-up ring 20 prevents the shell slippage in the groove.The outer wall of trocar sheath boss 23 inboards overlaps a spring 16, and during spring 16 naturalness, the inner chamber narrow of shell 11 can block the ball on the trocar sheath; Shell 11 be able to cover ball near an end of intubate during compressive state.Shell 11 is enclosed within on the trocar sheath 12, the diameter of step I24 is greater than the diameter of trocar sheath boss 23 in the inwall of shell 11 1 ends, and the distance in its other end inwall between step II25 and trocar sheath 12 outer walls is greater than the distance between trocar sheath 12 inwalls and annular groove 21 bottoms.
