Description
Technical field
This utility model relates to medical instruments field, particularly, relates to a kind of disposable artificial rupture of membrane crochet hook.
Background technology
In clinical birth process, often can run into the problem of puerpera's polyhydramnios, or normal labor needs artificial rupture of membrane to observe the situation of amniotic fluid, or need artificial rupture of membrane to flow out amniotic fluid, accelerate stages of labor.Frequent use syringe needle or cotton swab or metal pliers one's water breaks, all need palace mouth open large could one's water breaks to 3cm.In order to solve the problem of artificial rupture of membrane when palace mouth is not opened, a kind of apparatus must be used to carry out one's water breaks.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of disposable artificial rupture of membrane crochet hook, when cervix uteri mouth is not opened, only need medical personnel's shirtsleeve operation, the rupture of membranes of puerpera can be completed, slowly release amniotic fluid, bring out product million, shortening labor, termination of pregnancy.
For solving the problem, the technical scheme that this utility model adopts is as follows:
Disposable artificial rupture of membrane crochet hook, comprises sleeve and crochet hook, and described jacket casing is located on crochet hook, and described crochet hook front end is provided with barb.
Preferably, described barb is 2.
Preferably, described crochet hook end is provided with and pushes away handle.
Preferably, the barb of described crochet hook and push away between handle and be provided with banking stop, described banking stop diameter is greater than sleeve diameter.
Preferably, described crochet hook front end is to the length 3-5cm longer than the length of sleeve of banking stop.
Preferably, in described sleeve, be also provided with the limited block preventing crochet hook from rocking, described limited block be provided with the spacing hole passed for crochet hook.
Preferably, described sleeve is also provided with non-slipping block outward.
Compared to existing technology, the beneficial effects of the utility model are: this utility model, when cervix uteri mouth is not opened, only needs medical personnel's shirtsleeve operation, can complete the rupture of membranes of puerpera, slowly release amniotic fluid, brings out product million, shortening labor, termination of pregnancy; And push away the setting of handle, limited block, banking stop and non-slipping block, decrease the probability that error appears in one man operation, ensure that the safe and reliable of operation.
Accompanying drawing explanation
Fig. 1 is that this utility model does not use structural representation;
Structural representation when Fig. 2 is this utility model use;
Wherein, 1 is sleeve, and 101 is limited block, and 102 is non-slipping block, and 2 is crochet hook, and 201 is barb, and 202 for pushing away handle, and 203 is banking stop.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, disposable artificial rupture of membrane crochet hook, comprises sleeve 1 and crochet hook 2, and described sleeve 1 is set on crochet hook 2, and described crochet hook 2 front end is provided with barb 201.
In a preferred embodiment, disposable artificial rupture of membrane crochet hook, comprises sleeve 1 and crochet hook 2, and described sleeve 1 is set on crochet hook 2, and described crochet hook 2 front end is provided with 2 barbs 201; Described crochet hook 2 end is also provided with and pushes away handle 202, barb 201 and push away between handle 202 and be provided with banking stop 203, and described banking stop 203 diameter is greater than sleeve 1 internal diameter, prevents crochet hook 2 from too much releasing the damage causing tissue; Described crochet hook 2 front end is to the length 3cm longer than the length of sleeve 1 of banking stop 203.
In a further advantageous embodiment, disposable artificial rupture of membrane crochet hook comprises sleeve 1 and crochet hook 2, and described sleeve 1 is set on crochet hook 2, and described crochet hook 2 front end is provided with 2 barbs 201; Described crochet hook 2 end is also provided with and pushes away handle 202, barb 201 and push away between handle 202 and be provided with banking stop 203, and described banking stop 203 diameter is greater than sleeve 1 internal diameter, prevents crochet hook 2 from too much releasing the damage causing tissue; Described crochet hook 2 front end is to the length 5cm longer than the length of sleeve 1 of banking stop 203.Also be provided with the limited block 101 preventing crochet hook 2 from rocking in described sleeve 1, described limited block 101 be provided with the spacing hole passed for crochet hook 2, crochet hook 2 slides in sleeve 1 through spacing hole; Described sleeve 1 is outer is also provided with non-slipping block 102.
Before cylinder uses, barb 201 is hidden in cover 1 (as shown in Figure 1), when appropriate location shifted onto by sleeve 1, promotion pushes away handle 202, and crochet hook 2 is released, under the position-limiting action of banking stop 203, ensure that crochet hook 2 can not be released long (as shown in Figure 2), to pull back afterwards crochet hook 2, utilize barb 201 to be broken by film hook, release amniotic fluid.
to one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of this utility model claim.
