Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of modular construction of inflating anti-bedsore mattresses, specifically is the connecting device of a kind of anti-bedsore mattresses and air pump.
Background technology
The anti-bedsore mattresses of inflated type need charge into air by the outlet nozzle of the outside air pump gas inlet rubber tube by anti-bedsore mattresses in use, thereby improve the comfort level of sickbed patients in anti-bedsore mattresses, prevent the generation of decubital ulcer.In traditional product, the gas inlet rubber tube of anti-bedsore mattresses is general direct to be connected with the outlet nozzle of air pump, and there is easy aged shortcoming in sebific duct in life-time service, numerous, the effort of dismounting in the use, simultaneously under powering-off state, the gas in the anti-bedsore mattresses also leaks easily and influences result of use.
Summary of the invention
Technical problem to be solved in the utility model is, gas leaks in a kind of simple in structure, easy to use, may command anti-bedsore mattresses the anti-bedsore mattresses and the connecting device of air pump are provided.
The connecting device of anti-bedsore mattresses of the present utility model and air pump includes a pedestal, be provided with some inner connection tubes in the pedestal inboard, the gas inlet rubber tube of anti-bedsore mattresses and inner connection tube socket are fixed, present external side is provided with the outer connecting pipe that connects with inner connection tube, the external diameter of outer connecting pipe matches with the internal diameter of air pump outlet nozzle, simultaneously on the outer wall of outer connecting pipe, have annular seal groove, in the sealing ring ring recess, be mounted with sealing ring.
Described pedestal is provided with has certain elastic elastic hook, shell end at the air pump outlet nozzle is provided with the positioning step that can match with elastic hook simultaneously, when above-mentioned outer connecting pipe inserts the air pump outlet nozzle, described elastic hook can articulate mutually with positioning step, throws off to prevent outer connecting pipe and air pump outlet nozzle.
Described elastic hook is arranged on the front end of an elastic pressuring plate, and the middle part of this elastic pressuring plate is connected with pedestal by one section elastic cantilever.
The connecting device of anti-bedsore mattresses of the present utility model and air pump also includes a capping, described capping inboard is provided with the blind hole that matches with above-mentioned outer connecting pipe, the housing of capping simultaneously is provided with the capping positioning step that can match with elastic hook, when above-mentioned outer connecting pipe inserts described blind hole, described elastic hook can articulate mutually with the capping positioning step, takes off from outer connecting pipe to prevent capping.
This utility model is simple in structure, connection is reliable, and it can carry out dismounting with the air pump outlet nozzle easily; In addition, can carry out shutoff to the air inlet of sebific duct by capping, thereby can when air pump is not worked, keep gas in the bedsore cushion, improve comfort.
Description of drawings
Fig. 1 be this utility model with the structural representation of air pump outlet nozzle connection status;
Fig. 2 be this utility model with the structural representation of capping connection status.
The specific embodiment
As shown in Figure 1, pedestal 1 inboard of the connecting device of this anti-bedsore mattresses and air pump is provided with some inner connection tubes 11, the gas inlet rubber tube 4 and the inner connection tube socket of anti-bedsore mattresses are fixed, present external side is provided with the outer connecting pipe 12 that connects with inner connection tube, the external diameter of outer connecting pipe matches with the internal diameter of air pump outlet nozzle 2, simultaneously on the outer wall of outer connecting pipe 12, have annular seal groove 13, in the sealing ring ring recess, be mounted with sealing ring 14.
As shown in Figure 2, this device also includes a capping 3, and when pedestal 1 was thrown off with the air pump outlet nozzle, the blind hole 31 of capping inboard can match with outer connecting pipe, with its sealing.The housing of capping simultaneously is provided with the capping positioning step 32 that can match with elastic hook, and when outer connecting pipe 12 inserted blind hole 31, elastic hook 15 can articulate mutually with capping positioning step 32, takes off from outer connecting pipe to prevent capping.
